I’m looking for a temperature sensor that will report temperature changes of 0.3°C (or less) to Home Assistant. I’d like it to be wifi/thread-based or pluggable via ethernet port and if necessary, I could e.g. power it over USB. I’m not familiar with soldering boards, so I’d like to buy something that only requires inserting a battery.
I’ve recently purchased two Qingping Temperature Sensor (Thread), but unfortunately they only transmit temperature changes of at least 0.5°C, which makes them useless to me.
There is an old thread from April 2021, so I wonder which sensors have been made available in the past 2.5 years since. Thanks!
