Interested in the same but usb powered myself. For now using https://www.mylocalbytes.com/products/snzb-02-zigbee-temperature-humidity-sensor sensors. Got 5 of those but considering getting more. Had these for a couple of months but the battery still reports 100% for all of themm which is a bit suspicious and optimistic. Will update this oost once the battery will report anything other than 100.
I'd take USB-powered, not a problem. Just something that can be plugged into continuous power.
The packaging claims a run-time up to 2 years, but I assume that's for very optimistic placement right next to a hub. But who knows, maybe it's just a startup issue with reporting and it'll actually keep for a while.
Yes, i suspect its an issue in reporting that for a 2 year claim to still be 100% after a few months. But as a sensor they work great, experimented leaving it in the fridge to monitor that for example, thinking of getting more sensors.
But inalso live in a 1 bed flat. So yes distances are not massive at all.
