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 to get them all connected.
When searching for “Zigbee Smoke Detector” I came across those four models:
So: Any recommendations which one to use? One of those or any other? They should be approx the same price range.
Ideally I would be able to recharge them via USB but it seems like they all need batteries, so I would like the battery to last as long as possible.
