The Aqara temperature sensors[0] wouldn't stay connected to my SkyConnect USB dongle. No issues with my Zigbee switch and thermostats though, so I think some vendors aren't fully Zigbee compliant but it's probably the exception.

I've had great results with their buttons/light switches and Home Assistant Yellow, and the SkyConnect prior to that, for what its worth. I especially like the PoE version of Home Assistant Yellow - can power the entire server from its ethernet port.

Do you use ZHA? I had to change to zigbee2mqtt (and thus get more compatible device to go with it) to make my Aqara sensors stop disconnecting.

Probably? It's a SkyConnect on Home Assistant OS.

What would you recommend for a ZigBee thermostat?

I'm not who you asked, but I replaced my baseboard heater thermostats with the Sinope Zigbee ones and have been very happy with them. I think their products only work with heating systems though, not heat + A/C.
