If you already have ZigBee setup it's easy to use these, if not maybe look for something else.

I also use one of these outside with a 3D printed case. Still going strong after about 18 months!
Same one I use, also made an enclosure to 3D print and protect it from rain. It's been going on without issues since 2020 https://www.printables.com/model/169425-xiaomi-aquara-thermometer-outdoor-case
I have two of these outside, jankily sealed up with electrical tape, and they've survived the British weather for a year so far.
