Hi all,

I'm looking for zigbee temp and humidity sensors that work with HA, are pretty accurate and either are mains powered or have use a battery that can be recharged e.g. AA or AAA.

I like the Sonoff SNZB-02D, but they use disposable coin cell batteries.

One I found that looks like it might fulfill these criteria is

But they're kinda spendy. Anyone have any recommendations?

Fair point! As far as I can tell, the temp sensors are just beacons - anyone can connect and see that somewhere in your house it's 72 °F, but who cares ¯\_(ツ)_/¯

If you're running on a Raspberry Pi, you can just use the onboard BT, whose drivers are updated regularly.

ZigBee ones get occasional updates automatically detected through HA, and have to be moved to somewhere near the controller to update. I assume, as temperature and humidity sensing hasn't changed, that these are security patches.

BT ones get no updates, which either means their security goes unpatched, or it really doesn't matter when all they do is shout out measurements into the void.
