Something similar can also be done in Home Assistant with tommysense and espectre if you are interested.

There are also TOMMY ( https://tommysense.com ) and ESPectre ( https://espectre.dev/ ) in addition to the options listed under 'Smart Light Sensing' which are more Home Assistant oriented wi-fi sensing sol

Founder of TOMMY here. I'm glad you like the ESPHome support. It was one of the most requested features before implementation. Regarding the lifetime license for Discord members, that's primarily to ensure that beta testers aren&#

I can understand that. I used to do a lot of game streaming with Parsec and ended up with a similar setup. Right now, TOMMY only use Wi-Fi and doesn't support using ethernet for the communication with HA and Wi-Fi for peer-to-peer comm

It's possible to have the devices in-wall, but it might not be that practical as you point out. Or at least they would have to be taken out once for flashing, then OTA updates would reduce or eliminate the need for reflashing further.

Thanks! I'm glad you like it. Sounds like a great project. Using the Wi-Fi signal directly might work in your case. It would be nice to go back to actually using the bedroom as a place to sleep and not look at the phones all the time :

I'm connecting them to a 10000 mAh powerbank which lasts 2-3 days I think. But I think it's pretty specific to the board you have.

by mike2872 11mo ago
Actually, you are right. I confused myself. You would need to have them connected to the same Wi-Fi as that determines the bands and channels they communicate on even though the communication is peer-to-peer. How are your devices connected

Unfortunately not. Even though the concept is the same, Philips Hue uses Zigbee as the sensing protocol which isn't compatible with the Wi-Fi sensing TOMMY uses.

by mike2872 11mo ago
You actually won't need to configure a SSID at all. The peer-to-peer communication is handled by the devices internally without any manual setup.
13.
by mike2872 11mo ago
Yes, if I understand you correctly then it already works with that setup. So you can have the ESP32s over ethernet and it still works as long as it's on the same network as TOMMY (Home Assistant Add-on or Docker). Only thing to keep in

Thanks, I'm glad you like it! Let me know how it works for you. And if you need any help, feel free to reach out. A zone is 2 or more devices. So 2 works just fine. Instead of a straight line, image two flashlights pointing at each oth

Yes that would work. They don't need to be connected to the router on Wi-Fi, it can be ethernet too. The ESP's will connect with each other peer-to-peer.
16.
by mike2872 11mo ago
Right now it is a requirement that the device running TOMMY (e.g. Home Assistant) and the ESP32 nodes are on the same network. The communication between the ESP32's are peer-to-peer without needing the router, but the data needed for a

ESPresense and TOMMY solve different problems right now. ESPresense tracks specific people with IDs (even when stationary), while TOMMY detects anonymous motion across zones. For your use case, ESPresense is probably the better fit currentl

Unfortunately it doesn't support this yet. But it's on the roadmap and something I want for my apartment.

From my understanding, Wi-Fi sensing requires at least two antennas (transmitter and receiver) to measure signal disruption. This could be one device with both antennas, or two separate devices. There are also techniques that use one contro

That was also one of the papers I read early in my project. Really fascinating stuff. The use cases for Wi-Fi sensing are vast. Motion and presence sensing is only scratching the surface. My goal is for TOMMY to follow this technology and m

by mike2872 11mo ago
Yes it works outdoor too. Although experimenting with device placement is crucial for good results. I think there are different battery powered ESP32 you can buy. I have some of mine set up with small power banks.

by mike2872 11mo ago
Sounds good. Your application should be approved now. Otherwise let me know.

While theoretically possible, this would be a very involved surveillance method compared to simpler alternatives that already exist (cameras with telephoto lenses, thermal imaging, simply watching schedules, etc.). Wi-Fi sensing isn't

I believe that was the initial paper which really started the Wi-Fi sensing research. Although a lot of research has come after that. It's a really fascinating technology with a whole range of possibilities beyond just motion and prese

Haha, didn't even think of that song by The Who before someone mentioned it in another comment.

by mike2872 11mo ago
Sounds good! Talk to you there.

by mike2872 11mo ago
I'm glad you made an exception, though. I'll help you get the board flashed.

No calibration is needed for the motion sensing. You can adjust sensitivity in the dashboard if you get false positives though. In the future, when I add stationary presence detection, there is a good chance a small calibration will be need

Great questions. Neighbor detection: I haven't had issues with neighbor movement affecting detection in my testing. The devices form a mesh within your defined zone, so they're primarily sensing disruptions between your own nodes.

Could you open a support thread in the Discord channel? Some boards have some quicks to them. But it's all been solved by other users before. I'm sure there's a solution to your board too.
