I am looking for a temperature sensor so I can check the room temperature and humidity.
Which brand and model would you recommend?
I’m looking for one which has:
My plan is to setup automation to turn on or off airco when the room temperature is X degree.
I have Xiaomi 's. Batteries lasted 2 years before I had to replace them.
I use the aqara. Very small and reliable. IN best case pair them at the place where they will be positioned
Those are the latest I bought. Fine so far

Just out, didn’t try:
are you happy with their accuracy ?
I bought 3 and it seems they work fine with HA, but I have no idea how to check if they are accurate 
I compared against digital thermometer which I have and the results were similar, so I think they’re accurate.
Did you use a gateway with them?
I use my Aqaras with deConz. That’s my “hub”.
Thank you!
Does this mean that you don’t need more hardware than the Raspi? As I understand this must run on a PC?
I run HA and deConz on a PC but I would think you could run both on a Raspi.
Yes, deConz will run on Pi.

Thank you!
Great, now i’ve learned a lot.
Hi Chris, got the same , but how do you integrate them in HA ?
Got 3 different aqara models for zigbee, all of them terrible, not accurate at all, bad signal.
Trying to find some proper ones…
The only reliable ones I have are super old 433 based ninjablocks humtemp sensors which last forever, even outdoors!
Would love to see a proper review of such sensors with proper tests…! Maybe a video idea for andreas spiess 
I’m having this issue now.
Had SkyConnect with Aqara and they seemed great but then had one recently stall.
Trying Sonoff Zigbee 3.0 USB Dongle Plus and it seems even worse with Aqara. 10min reporting intervals and no battery status.
You find a better combination? Contemplating going Tuya WiFi ones even though I dont want to install their app.
