Calibrate temperature on Third Reality temperature/humidity sensor

Devices & Integrations
1

Anyone using a Third Reality 3RTHS24BZ temperature and humidity sensor and notice that the temperature is a bit off? Mine reads about 1.5*F low, relative to a Thermworks digital thermometer. The ST Advanced Web page has a parameter for temperature offset but I cannot find a way to actually adjust it.

There’s no temperature offset setting in the device’s preferences (device card → three dots → …)?

So there must be a setting.

You nailed it–there are offset settings for both temperature and humidity there! Doh, it never occured to me to look there. Thanks very much.
