For our family house and for the house of my mom I would like to change from traditional 433 smoke detectors to Zigbee. Right now I have almost nothing, just a Raspi with Home Assistant on it. I would mount approx 30 smoke detectors, some water leakage detectors and of course a number of repeaters t…

[image] fair_dinkum: ave Z May I ask if you’re using Z-wave JS? If yes, did you manage to include them without issues? I’m asking because I’m considering to buy some but I see they are not officially supported in Z-Wave JS supported devices DB: https://devices.zwave-js.io Thanks!

Yes, using Z-Wave (Aeotec USb-Stick) and these Smoke Alarms since Years with no probs. If I would buy new, I would go for an RJ45 POE Z-Wave Device, rather than an USB Stick…

Allright, thanks they do work indeed. Including them in Z-wave JS was a breeze. I did notice though they there is no actual sensor entity that changes state when smoke is detected, just a switch entity and a light entity which both seem to do the same thing (turning the siren on and off). Does any…

The Frient/Develco and Bosch I mentioned before have a binary sensor with type smoke that will trigger on detection.

Yes, I have them connected to ZHA now. [Screenshot 2025-02-07 at 20.20.12] And these are the options for the Develco/Frient Smoke and Heat detectors: [Screenshot 2025-02-07 at 20.21.39] [Screenshot 2025-02-07 at 20.23.00]

I just buy First Alert ZCOMBO z-wave version from bestbuy.com I am able to add it into my HA. it is abit tricky thou. put in batteries and leave the battery caddy out then go to your zwave intergreation click to add device… press the test button and hold test button as you push in the battery …

These two seem great, and I was very excited to learn about them, especially cause I can’t go with hardwired options. Bosch is a trusted brand and it having an mqtt controllable siren is cool too. But I’m finding a lot of unfavorable (1-2*) reviews on them on Amazon.de , either complaining about fre…

I have three Bosch in the house and had one in the garage outside. The ones inside have never went off yet, so no false triggers. Batteries are still at 100% after 14 months of use. They are supposed to last 5 years, which is half of the lifespan. With the original SHC II and Z2M you can set the se…

Have you been able to start the alarm or make some kind of sound from within HA? There is a speaker symbol, and it’s possible to unmute, as well as an “advanced” view where you can pick a sound, level and duration and a play button, but so far I haven’t managed to make them sound other than pushing …

Recommended smoke detectors - reliability, no false alarms, battery life?

May I ask if you are still happy with the BSD-2? I am not planning to run it with ZHA but with z2m. Have you had any problems with false alarms?
