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?

Of course! From an end-user the experience between Bluetooth and ZigBee sensors is basically indistinguishable, except for range.

I have a detached garage, on the opposite end of my property from my HA controller, so the Bluetooth sensor out there specifically was a little flaky. The BT sensor is rated for ~160 ft but realistically it's 50-100 ft if your home has walls.

Swapping that one sensor to ZigBee so it could tie into my mesh network solved the problem. All other BT sensors have had zero issues, and their AA batteries unsurprisingly last longer than the 3R ZigBee AAAs, but both last at least 6mo.

Some Shelly devices can be used as "Bluetooth repeaters" but I'm unsure of the specifics of how that works.
