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?

I got these: https://www.pearl.de/a-ZX7311-3110.shtml;jsessionid=nAF84CDBD95715305C44924424332C488?vid=953&curr=DEM

Not sure how precise they really are but they connected easily. Have them running for 34 months now, they run for months on rechargable AAA (I got high quality ones, Varta I think)

Isn't this the same tuya linked for 5 usd elsewhere in the thread?

Seems like they have the same chip. I didn't buy for the price in the store, it seems to change frequently
