Ask HN: WiFi smoke detector that doesn't require Internet access

1 points by fml11223344 3y ago ↗ HN

I'm looking for a smoke detector and CO2 sensor that I can connect to a private isolated Wi-Fi network. I want to be able to get the alerts and send to myself, but I really dislike connecting things to the Internet.

I find it hard to discover things like this because connected almost always means connected to a cloud server somewhere, with an app that polls that server.

Apologies if this question has been answered before, I've tried searching on here and on the greater internet but the ad copy is not very clear.

Thanks in advance!

Use meshtastic and an ESP32 wired to the detector.

Thanks for the info. Do you mean something like the linked YouTube? https://youtu.be/NuwXAvgs4Ho

I like it and it certainly doable but it seems a little janky to me. I really wish there was a hacker friendly, non-cloud "connected" solution. I know we're in the minority with that sort of thing and most people want user friendly..

Again, thanks! I will start looking for smoke detectors that I can read the state with an esp32 or similar (maybe just put one of the detectors next to and already running raspberry pi?). I guess I was thinking of an out-the-box solution but maybe I'm dreaming (-:
