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 think the options either that combination are limited. IKEA Zigbee devices use removable batteries, but they don’t have a temperature sensor. They do have a USB air quality sensor but it’s a bit more complex/expensive.
There are some good WiFi, Bluetooth or RF options with removable batteries but they won’t be Zigbee.
I’ve heard of some people modifying the coin cell devices to used a wired power supply, maybe that would be an option.
@thehatfox @ueiqkkwhuwjw Aliexpress has plenty of ones with a screen (its a low power LCD screen like a casio watch) that uses AAA batteries. - It has a backlight that you can put on to read it in the dark.
