I’ve got a temperature item I think mis-reports possible by 9 degrees (C) each time.
Is there something I can add to the incoming MQTT state to add 9 to the incoming number (without using a rule or seperate .js file)
Yes I know mqttv1 is old, I’ve moving, but slowly…this is one of the items that slows down my move because of how the sitemaps etc are working for item selction.
Number rm3_lounge_temperature "Lounge Temp (RM3) [%.1f °C]" <temperature> (g_rm3_lounge_samsung,g_temperature)
{mqtt="<[openhab:broadlink/c5_f9_b2_34_ea_34/temperature:state:default]"}
No. When you move to use Things and channels, you can apply an offset to the channel with a profile.
For v1 you are stuck with rule or js transformation, they don’t cost much.
