Welcome to

2

:

the business of LoRaWAN,

where we dive into this long range,

3

:

low power, wide area network

and its impact on your bottom line,

4

:

the latest sensors and proven real world

solutions.

5

:

I'm your host, Nik Hawks.

6

:

Since 2020,

when I stumbled into LoRaWAN via helium

7

:

while hunting for a lost paraglider,

I've helped thousands understand

8

:

how it works and how to use it,

and I'm psyched to do the same for you.

9

:

I've installed everything

from soil sensors

10

:

to weather stations to retail foot

traffic counters.

11

:

Coming to the conclusion

that LoRaWAN is rad,

12

:

so I built the only show on the internet

fully dedicated to unlocking its potential

13

:

for your business.

14

:

Let's dig in.

15

:

Today I'm joined by Vasya

Tremsin, the founder and CEO of Torch

16

:

Sensors, a wildfire detection company

using LoRaWAN connected smart sensors

17

:

to catch fires at the spark, often

within three minutes of ignition.

18

:

Thus, his story is wild in the best way.

19

:

He came up with the idea for torch

as a high school science fair project.

20

:

After watching wildfires devastate

communities near his home in the Bay area.

21

:

His prototype won awards

at international science fairs,

22

:

and one of the judges, Michael Buchwald,

co-founder of Leap Motion,

23

:

was so impressed that he helped

to turn the project into a real company.

24

:

Since then, Vasya has gone from student

innovator to startup CEO,

25

:

building a company that's now deploying

26

:

wildfire sensors in high risk zones

across California and beyond.

27

:

Torch sensors are solar powered

multi-sensor and devices that detect heat,

28

:

smoke and gas in real

time, covering ten acres

29

:

per unit and sending alerts at the moment

a fire starts.

30

:

It's like smoke detectors

31

:

for the outdoors,

but smarter, scalable and connected.

32

:

Via LoRaWAN

33

:

after the devastating LA fires

in January of:

34

:

which destroyed over 18,000 structures

and caused upwards of $250 billion

35

:

in losses, Vasya and his team

rushed into the burn zone to install torch

36

:

prototypes in neighborhoods

like Encino and Griffith Park.

37

:

Now they're scaling up with plans

for thousands of sensors

38

:

deployed this year, including partnerships

39

:

with cities, utilities and communities

trying to get ahead of the next fire.

40

:

To understand

41

:

where LoRaWAN meets real world impact,

you've got to talk to people like Vasya.

42

:

Here's our conversation.

43

:

Vasily, thanks for coming on today.

44

:

Of course. Yeah.

45

:

Thank you. Appreciate appreciate

having me. I'm psyched to have you.

46

:

We got the LA. Fire is top of mind here.

47

:

It's the end of March 2025.

Those were two months ago.

48

:

And that's where torch

kind of sprung to the the public.

49

:

Walk me through,

50

:

like how you guys deployed for that?

51

:

Did you know that stuff was coming?

52

:

Were you deploying as they went down?

Like what?

53

:

What happened?

54

:

Oh, yeah.

55

:

So definitely very unexpected event

as it is for LA

56

:

or the wrestling that two states

or the rest of the world.

57

:

I think the biggest learning

we have from that all of us have

58

:

is that, you know, wildfire is our

not just a seasonal problem.

59

:

It can happen year round

and it can happen anywhere.

60

:

So for us, you know, as a start up,

the story goes that,

61

:

during that time,

we were actually preparing for a S&P

62

:

500 utility deployment of several

hundred sensors on the East Coast.

63

:

And so we're basically

we're doing some last testing

64

:

and some last checks

about the connectivity.

65

:

And then, you know, January 9th happened

and we saw the news

66

:

and the Palisades fires

basically burning through all of LA.

67

:

And so that's when we realized, like,

you know, oh my God, like, this is

68

:

this is happening, this is historic.

69

:

And it's such a tragic situation.

70

:

And at the same time,

our technology is literally built

71

:

to prevent this and to stop things

like this from happening.

72

:

As a early stage

outdoor fire detection sensor.

73

:

And so we basically

just sprung into action.

74

:

My CEO was actually in England

on a family trip, and he flew out

75

:

the next day was in, in San Francisco

the the same afternoon.

76

:

Just because,

you know, the time difference helps

77

:

in this case a little bit.

78

:

And we talked about, you know, 25 sensors,

how much we could fit in the car

79

:

and just drove down with Starlink units.

80

:

Sensors like the whole doomsday kit, the,

you know, gas mask, etc..

81

:

And basically,

you know, we didn't really have any,

82

:

any access to red tape

or any connections going into this.

83

:

We just knew that our technology

is something that can help,

84

:

and our technology is something

that can not only prevent this

85

:

from happening in the future,

but also in the current situation,

86

:

can help to detect

ember fires, re ignitions, Re sparks, etc.

87

:

and so we just come up to areas

that were close to the fires,

88

:

like kind of yellow evacuation zones,

89

:

and we just started talking

to everyone on the ground

90

:

and giving them sensors

and giving them access to our platform

91

:

that had, all the data

for fires in real time.

92

:

So it wasn't just like the satellite data,

but it was also data from our sensors

93

:

that we were just putting out,

you know, in different locations.

94

:

And so slowly, you know, actually

little very quickly this snowballed,

95

:

into, you know, big deployments

like in, in different areas.

96

:

So we were putting them in

Encino and, and, woodland Hills

97

:

and like Hollywood

near the Sunset Fire, etc..

98

:

On the second day, within 24 hours,

we were escorted by the chief Ranger of LA

99

:

parks to the top of Griffith Observatory

and putting sensors there.

100

:

And then basically,

101

:

you know, just getting more

102

:

and more plugged in with the scene

103

:

and with the whole kind of emergency

response crew there.

104

:

So slowly, you know,

we were able to basically help them

105

:

to get real time on the ground data

to as many people as we could,

106

:

which was our mission from the start.

107

:

So we, you know, given this B2B focus

that we had in the B2B deployments

108

:

that are still going on,

109

:

we still were able to help just normal

people with data as much as we could.

110

:

Got it.

111

:

Okay, so the torch sensors

112

:

are just a they're a sensor

that has a little bit of AI in them.

113

:

They're living on the edge.

They're connected via LoRaWAN.

114

:

So they're basically saying,

hey, I see this fire. It's over here.

115

:

You guys should know about it.

And they transmit that back over.

116

:

Helium is LoRaWAN network.

117

:

Is that the

the kind of encapsulated story there?

118

:

Correct. Yeah.

119

:

So these are solar powered sensors.

120

:

They are they're unique in the sense

that they combine

121

:

a lot of different sensing modalities

that we never combine before.

122

:

So we have infrared camera,

123

:

optical camera, spectral analysis,

gas sensing, temperature, humidity.

124

:

All these things happen at the same time.

125

:

And one solar powered sensor that works

indefinitely with no recharging.

126

:

And yeah, we're able to

because we were able to utilize the helium

127

:

network specifically in LA especially,

there's such a wide amazing coverage

128

:

and they were able to reach basically

129

:

any part of the city immediately,

just with one click of a button.

130

:

They just online connect

and it will monitor any ignitions,

131

:

near the sensor, you know, indefinitely.

132

:

And so we were able to detect fires

within three minutes of ignition.

133

:

And, you know, anything

within with good line of sight,

134

:

up to ten acres for one sensor

with worst line of sight.

135

:

You know, we have to rely a little bit

more on the gas sensing,

136

:

but that's why we combine

all of them together.

137

:

We combine

all of these different variables,

138

:

even if each one of them by itself

is not that strong.

139

:

The combination is what creates the most

accurate fire detection in the world.

140

:

It's right and you've been doing this

since high school.

141

:

I saw that in early high school.

You figured out a fire detection sensor.

142

:

So this this isn't something that you just

kind of thought of yesterday.

143

:

Exactly. Yeah.

144

:

So the story goes that basically I'm, I'm,

I'm from a family of scientists.

145

:

Both of my parents are PhD scientists.

146

:

So growing up,

I wasn't really going to parties.

147

:

I just to the science fair projects

with my dad, since middle school.

148

:

And so we would always develop

every single year,

149

:

like a device that could solve

some kind of real world problem,

150

:

whether it was for the California drought.

151

:

We made the sensor that I could

basically project in 3D, like,

152

:

moisture around plants

so you can see water,

153

:

or it was a device

to detect skin cancer, etc..

154

:

And so the, the

my my senior year of high school,

155

:

it was 2017,

we had the crazy Napa Valley wildfires.

156

:

And I'm from near San Francisco,

eastern, eastern, San Francisco Bay area.

157

:

So we had, you know,

158

:

these crazy smoke clouds and obviously

kind of seen the devastation firsthand.

159

:

Always driving by these, these crazy fires

on the way to Tahoe, etc..

160

:

And so, yeah, basically that's that's

161

:

how I had the idea that, you know,

why is this never detected early enough?

162

:

Why is it always allowed

to get out of hand?

163

:

And it's still is, as we see every single

time allows to get out of hand.

164

:

So yeah, we did a science fair project

with my father who

165

:

a you know, he's a, UC Berkeley

166

:

PhD researcher, or as he used to be after

that was founded, our company together.

167

:

And that project won,

168

:

the first place

at the Intel International Science Fair.

169

:

And then after, when I was already

in college, University of Pennsylvania,

170

:

I got connected with a couple investors

in San Francisco

171

:

who were just very interested in the idea.

172

:

So that's how we found that the company.

173

:

Yeah, yeah, yeah.

174

:

You're like a super nerd.

You got an asteroid named after you.

175

:

It's like I got every single nerd credit

that's out there.

176

:

And then a degree in, what is it? Computer

science and economics.

177

:

So the economics side,

let's maybe talk about that is

178

:

what does the business

model look like here.

179

:

Do you go to

I mean I can imagine this being

180

:

you go to a city and you're like,

hey, I can tell,

181

:

I can tell you guys before

you'll know when a fire is starting.

182

:

And this is what the subscription

costs or how does that work.

183

:

Yeah.

184

:

So definitely the the best use case

for torch is protecting high value assets,

185

:

whether it's a city or a large business

or utility or there's a lot of different

186

:

use cases, but

it's this kind of hyperlocal detection.

187

:

You know,

there is obviously other solutions out

188

:

there, such as satellites

or large centralized camera solutions

189

:

that are very expensive

and protecting vast areas of land.

190

:

And all of those things,

they don't detect fires as early as we do.

191

:

And, you know,

192

:

and that's why we're focused on this

more high value asset, local detection.

193

:

Right. And local data.

194

:

So, the way it works from a business

perspective, yeah, we basically, you know,

195

:

have a both a Asus aspect to it

in terms of the subscription

196

:

and also, kind of hardware costs

to cover the hardware as well.

197

:

The exact, breakdowns

of that depends on this.

198

:

It's kind of like a seesaw situation,

right?

199

:

It depends

on the preferences of the customer.

200

:

Some some budget, some,

you know, just kickback situations require

201

:

like capital to be more loaded

upfront for certain sure contracts.

202

:

Some people prefer

the more of the subscription model.

203

:

But obviously there's a lot of monitoring

that goes into this.

204

:

We combine a lot of the data,

both from our local sensors on the ground,

205

:

as well as all the

206

:

third party fire information, air quality

information, weather information, etc.

207

:

win information.

208

:

So I if you combine those two things

together, you create the most accurate

209

:

fire monitoring

because you now have both the local data

210

:

physically coming from real time sensors,

as well as all the data

211

:

that's available to something

like watch duty or weather apps.

212

:

Right.

213

:

And so that's that's something

214

:

that has not been done before

and does not exist right now.

215

:

And so that's how you

216

:

have these super accurate models of where

the fire is going to go next of like how

217

:

how you can spread where can be put out,

where's the highest risk, etc..

218

:

So there's a huge,

you know, data element to this as well.

219

:

Yeah.

220

:

Super cool.

221

:

So you're basically deploying a

222

:

a weather station as well

because you're tracking all of that.

223

:

Is that wind speed and direction

I'm assuming or now.

224

:

So we yeah, we have

we use third party for wind speed.

225

:

We have temperature, humidity,

relative humidity, etc.

226

:

on our sensors.

227

:

Okay.

228

:

I'm just saying that the other

229

:

the reason that wind speed and wind

direction, etcetera matters.

230

:

And there's other sources for that.

231

:

But the reason that it matters is because

you would know where smoke came from.

232

:

For example,

233

:

if you know where smoke came from

based on both die and on the ground data,

234

:

then you kind of know,

like where it's going to go next, right?

235

:

So there's a lot of again, combining

both is super, super important here.

236

:

Yeah.

237

:

One of the funny things about LoRaWAN

and for those of us

238

:

who do it is

it's like a super nerdy fun thing to do.

239

:

And you're like, oh,

I'm gonna get this codec.

240

:

And this uplink just came through.

241

:

But it turns out

when you're selling this stuff,

242

:

no one really cares

about hearing about it.

243

:

When you're talking to a customer,

244

:

do you ever mention LoRaWAN

or only if they ask about it?

245

:

Yeah. No. No one. Really?

246

:

I think in general, customers, care more

247

:

about the value that we bring to them

and how much money we can save them.

248

:

How much?

249

:

How much,

I guess, like emotional, relationship

250

:

they have with their assets

and their their their belongings.

251

:

And it can, you know, burn up in a fire.

252

:

Sure. Specifically LoRaWAN. Yeah.

253

:

I think it's something that allows us

to create this, like one click solution.

254

:

I just press a button and it works.

255

:

And like seeing that is much more powerful

256

:

than saying specific details

about how we're going to do that

257

:

when they ask, of course.

So we describe it as well.

258

:

Yeah.

259

:

Right on.

260

:

And do these things

also have cell backhaul as well.

261

:

Or it's they're just running off LoRaWAN

just is there a an option for you,

262

:

depending on what coverage

is like to use different radio protocols.

263

:

So right now we have right now,

in the current version of the sensors,

264

:

we are using only LoRaWAN.

265

:

We have a, a couple different

developments in terms of IoT solutions

266

:

that I don't want to talk about right now,

but they're coming out really soon.

267

:

That will also basically be other options,

not just LoRaWAN.

268

:

Super, super cool. That's right.

269

:

I mean,

I always like to hear about LoRaWAN,

270

:

but it's good to have backups,

you know, when you need them.

271

:

Okay.

272

:

So when you're

273

:

going coming back to the business side,

when you're coming into a customer,

274

:

if it was me, I'd be looking at whatever

going into a new city to,

275

:

I don't know, in Oklahoma or Tuscaloosa

or Chicago or whatever and say,

276

:

hey guys, looks like you guys

might have a problem with fire detection.

277

:

Here's how much I think, here's

how fast I think we can detect it.

278

:

And here's

what I think the savings will be.

279

:

Or is the pitch something

a little bit different.

280

:

So it depends.

281

:

It depends obviously significantly

on who we're talking to.

282

:

I think if we're talking to big,

utilities and businesses,

283

:

the biggest pitch is that, you know,

we are we are saving this amount of money,

284

:

especially not just in terms of damages

that happened once a fire is there,

285

:

but also just in the sense

of like labor costs of monetary.

286

:

Right?

287

:

There's a lot of labor costs for monetary

and a lot of labor costs for coming

288

:

and checking on different things.

289

:

If you have remote plug and play sensors

that work,

290

:

indefinitely for solar power,

that saves you cost significantly, right?

291

:

So we focus more on that

when we're talking to cities on landmarks.

292

:

It's a little bit more focused on,

you know, protecting the city's history

293

:

and like the cultural aspects

and a little bit

294

:

more of an emotional pitch

towards that area.

295

:

I just, you know, that kind of topic,

I guess

296

:

the money aspect also matters a lot.

297

:

But this a little bit of a different pitch

there. Yeah.

298

:

Oh, interesting. Okay.

299

:

So just depending on the customer

you're tailoring I mean that makes sense.

300

:

You're telling the pitch them

301

:

and making sure that you're serving

the need that they have.

302

:

Of course. Exactly.

303

:

I always, I was pitching to the people and

and what connects them directly.

304

:

Right. Got it.

305

:

And then it sounds pretty cool

in that for folks

306

:

watching this who are wanting to deploy it

towards sensor.

307

:

Is that something I think you and I had

first talked when I was I mean, I'm

308

:

down in San Diego

309

:

and it was going on in LA

and I saw this thing like, hey, you know,

310

:

I want to put torch torch sensors

anywhere.

311

:

Is this something that you're going

312

:

to roll out for homeowners,

or is it just going to be street

313

:

kind of B2B beta G which B government

is going to be any kind of B2C aspect?

314

:

Should I be thinking

about protecting my neighborhood?

315

:

Yeah.

316

:

So currently we are focused

more on B2B deployments because, you know,

317

:

that's been going well.

318

:

And we have these, you know, multi hundred

319

:

sensor deployments that are going towards

protecting big assets.

320

:

Of course, even you know, me

personally as a founder,

321

:

I love the whole consumer angle

322

:

and of course very interesting

and fun to build up business.

323

:

And so we definitely have that in the plan

324

:

right now,

just operationally towards deployments.

325

:

We want to focus on continuing to prove

our technology with bigger customers,

326

:

taking their feedback

and really proving it through

327

:

use cases of fires happening,

how much money was saved, how many assets?

328

:

We protected different locations around

the United States, different stakeholders.

329

:

And when you prove it through that,

then it's easier

330

:

to get into the insurance business

and the other partnerships.

331

:

I can really quickly you know, basically

snowball the whole consumer angle as well,

332

:

because as soon as you have

333

:

an insurance partnership,

they can have lower premiums, etc.

334

:

it's really easy to spread

335

:

the safety net across entire communities

and protect them.

336

:

That said, you know, even though

337

:

we're not focusing on that as as heavily

right now,

338

:

we're still doing

we just dropped this La beta program

339

:

where we are, focusing on La residents

and just giving them, 50,

340

:

you know, limited amount of 50

torch sensors.

341

:

So we want to get, feedback

and learn from consumers as well,

342

:

even though we're not directly

selling to them right now.

343

:

We want to be able to give it

to a limited,

344

:

you know, set of people

who are very interested

345

:

and just passionate about the technology

and the subject and learn from them

346

:

and what their desires

and what their needs are,

347

:

and then create a solution for consumers

that is very tailored towards their needs,

348

:

very tailored towards

their wants and their, I guess, use case.

349

:

Yeah, yeah, yeah.

350

:

I mean, I want, I want to know

when my neighborhood catches on fire.

351

:

So as soon as those things are live

on the website for me to buy, let me know.

352

:

Is there anything else that

353

:

people should know before we sign off

about, about torch sensors?

354

:

Yeah,

I think, you know, we have a, again, like

355

:

I said, a lot of inbound interest

from a lot of different businesses, etc.

356

:

and of course,

357

:

especially homeowners and communities,

especially after the LA fires.

358

:

We're still looking to partner

with a few more,

359

:

you know, big B2B partners right

now, especially with governments or with,

360

:

businesses

that want to protect their assets.

361

:

We have,

362

:

you know, about, I would say, hunt 102

hundred sensors left for the spring.

363

:

And, yeah, we would love any,

you know, interest,

364

:

any more interest from partners

that want to the wants

365

:

to test out our technology

or want a demonstration of how it works

366

:

or just want to see, you know, a fire

being detected on their property.

367

:

Always,

always ready for those partnerships.

368

:

Yeah.

369

:

That's right, because you've done a bunch

of, detection with prescribed burns.

370

:

So it's pretty easy to say,

hey, there's there's no fire.

371

:

Watch this.

Now there's there's a fire. Exactly.

372

:

Yeah. We can also

we also do a lot of demos.

373

:

So, you know, go to a parking lot

or a certain

374

:

area of the customers

that are okay with burning a small flame,

375

:

and we'll put sensors around it

at different distances

376

:

and in different scenarios

in different kind of locations,

377

:

and then light up a flame it with show

detecting and everyone getting call

378

:

and a text message, an alert.

379

:

And it's like, oh,

it's like a magic trick, right?

380

:

Everyone's oh my, yeah, it works.

381

:

And it's always very, very effective.

382

:

And and fun to do for me as well.

383

:

Yeah, yeah.

384

:

Well, I'd be remiss

if I didn't ask this then.

385

:

How far? Like,

what are the parameters for detection?

386

:

Can you see something a mile away?

387

:

Ten miles away, 200ft away.

What does it look like?

388

:

Yeah. So, like I said,

we focus on this hyperlocal approach.

389

:

So one sensor covers up to ten acres.

Ten acres.

390

:

So a ten acre circle is a circle

with a radius of 113m.

391

:

That is our kind of bread and butter.

We do.

392

:

We can detect something

393

:

farther away if it's a very large flame,

if it becomes something big.

394

:

But we want to focus on things

that are basically the size of a campfire,

395

:

or the size of a car,

and the size of a car within three meters

396

:

within three meters from up to ten acres

is kind of our main claim.

397

:

Yeah. Oh, interesting.

398

:

Okay,

so in order to do much bigger deployments,

399

:

you either have to change the sensors

400

:

or just have a really dense

sensor deployment.

401

:

Yeah. Yeah.

402

:

So if you want, you know, let's say

cover a forest, that's very dense.

403

:

We would rely more on gas sensors.

404

:

But also like I said before,

that is not the primary use case here.

405

:

Right.

406

:

Because we want to protect the high

value assets that hold a lot of value

407

:

to their owners.

408

:

And they need this local,

409

:

very i.q protection at the stage

of a small campfire within three minutes.

410

:

Boom. Know about it, put it out.

411

:

Yeah, yeah, that's it's way easier

to put out a campfire than an entire city

412

:

that's burning.

413

:

Okay. Yeah.

414

:

We'd like to use this,

phrase that, you know, in, in the kitchen,

415

:

the the chef puts out a fire on the stove.

416

:

They don't call up the firefighters.

417

:

So same, same concept here.

418

:

So, you know, about early enough. It's

very easy to stop it.

419

:

You don't need to even involve anyone.

So love it.

420

:

Dude, thanks so much for coming on.

421

:

I know you're super busy as a founder,

422

:

so I appreciate you taking the time

to share torch sensors with us today.

423
