Temperature offset

#1

1) Give a description of the problem
I’m trying to recreate a CoRE piston that compared my room temp sensor value to the thermostat heating setpoint with an offset of -1 deg F.

2) What is the expected behavior?
The piston will close the Keen vent in the room to 20% if the temp is 1 deg F below the heating setpoint.

3) What is happening/not happening?
I’m not sure how to add the offset value to the line of code since it was included in the original CoRE.

Use in value field
{[thermostat:heatingSetpoint] -1}

Switching heating for cooling where necessary

I tried the value field but it will only accept numbers. I tried the expression field and it took it so I’m thinking that solved my problem. Thanks!

Great! I usually give both value and expression replies but I’m on mobile and it was a lot of extra typing. Only difference is you won’t need the curly brackets in expression field.
