ᐅ Interconnected Smoke Alarms – But Which Ones?

Good morning everyone,

I still need smoke detectors for the house. It is important to me that the smoke detectors are interconnected (smart home capability is not absolutely necessary). The current plan is to have 4 Homematic smoke detectors in the required rooms and the rest with Xiaomi detectors (which use Honeywell technology). Which ones do you use? Do you have any tips?

Which system should they feed their alarm signal into, or is it just about having all alarms trigger when one detects something?

Based on a recommendation from a firefighter, we installed the Hekatron smoke detectors Genius plus x. After 10 years, you can throw away the actual detector but remove and reuse the radio module. By the way, it is a top performer in Stiftung Warentest (German consumer tests), with practically no annoying false alarms, unlike many competitors. Despite thick concrete walls, the signal reception is excellent.

We have them installed in our hallway, basement, basement utility room, ground floor hallway, upper floor hallway, attic studio, and in the bedrooms. For networking, it is important that the radio modules come from the same batch; buying additional units later is problematic. So, it’s best to buy all of them at once, at least the radio modules!

There is no smart functionality, but if I were to receive timely notification while on vacation that my house is on fire and I couldn’t do anything anyway, it would probably be better than missing out on the holiday enjoyment. Oh, and you can even read the status via an app.

Actually, that’s enough for me. If anything, the battery status should be accessible via IO-Broker.

Then you need to check which smoke detectors IO-Broker can communicate with. Otherwise, the Hekatron or FireAngel models are quite reliable.

Isn't there a more affordable alternative? The Hekatron models with radio modules are actually more expensive than the Homematic ones.
