I‘m currently looking for a smoke detector with the following characteristics: Can be hooked up to openHAB No need to be run via a cloud service (e.g. smart life) Group alarm (meaning: if one gets triggered, all get triggered), ideally via the detectors talking straight to each other (rather than:…

Quick update: I followed @Oliver2 ’s recommendation in the thread… [image] Investigation of smoke detectors usable with OH Homematic smoke detectors (life time battery supply) … and settled for the HmIP-SWSD . My main rationales: Available in my region (Germany) Not cheap, but also not too e…

I have a solution that works but it might be a bit convoluted. I have 4 x Kidde KF10 mains/battery backed smoke alarms plus a CO detector. They all talk to each other so if one detects, they all sound. You can get an SMK23RU base unit that has a relay that closes when any alarm sounds. In my case, …

[image] barneyd: Smoke alarms from Kidde not Google. The Nest Protect is generally considered to be one of the best devices on the market. I agree that you have to be careful about companies (not just tech companies) going into unfamiliar markets, but that doesn’t preclude them from being goo…

You know these threads ? [image] Investigation of smoke detectors usable with OH Home Automation Hi all, I have been researching different smoke detectors usable with OH. This thread is meant to collect the information I have been digging out, and hopefully fo…

Thanks @barneyd , @rpwong & @Wolfgang_S . I am a bit embarrassed I did not find those great threads myself (I did do a search before creating mine though). I was hoping for the one dominant solution, but this appears not to be the case. Will investigate.

I had exactly the same arguments. Good choice.

Is anyone aware of a good documentation on the available channels of the HmIP-SWSD smoke detector? I remember a rather large but convoluted and mostly useless .pdf from eQ-3, so I am curious on whether there’s a good list somewhere of what the channels are, whether they are read/write and what the c…

Be extra cautious about wireless smoke detectors. Here’s why. You should classify your devices in separate groups, depending on their criticality. For example, if a motion detector for stray cats on my new lawn doesn’t always trigger the water sprinklers, I can tolerate that. Turning lights on and …

Thanks! Very valid thoughts, and generally the problem of every security-critical device being connected via a shared medium (like 868 MHz). I’m not sure on the Nest smoke detectors (–> whether they require WiFi to perform a group alarm), but the HmIP-SWSD’s don’t appear to require the CCU / AP to …

[image] Cplant: I’m not sure on the Nest smoke detectors (–> whether they require WiFi to perform a group alarm) The Nest Protect uses Weave for interconnectivity. Google discusses it in detail here, probably because it’s reasonable for people to assume that they require an active network con…
