wayland/scd30-co2-rh-temp/set-temperature-offset
The on-board relative humidity and temperature sensors are influenced by thermal self-heating of SCD30 and other electrical components. A temperature offset can be specified to compensate for self-heating. Temperature offset value is saved in non-volatile memory. The last set value will be used for temperature offset compensation after repowering.
