Hi, check out my post. I use this in a drinking water boiler. Temperature control in an electric boiler for heating food water in a private house I put such sensors on all heating control points. Methods for controlling room temperature using Aqara devices
This is the sensor data (Aqara square thermometer) from my direct water pipe from the boiler, the temperature on the boiler is set to 50, the reading (at peak) is approximately 43 degrees.
