I am having difficult time to create a piston that control the Nest Thermostat based on a single Netatmo remote sensor temperature reading. Say, if the Netatmo sensor temp reaches or rises to 77F, then set the Nest “desired” temp 2 degrees below the current temperature on the Nest (which is very far away from the Netatmo sensor). Then, after 10 minutes of running the AC, then I want to set the Nest’s temp 5 degrees above the latest current temp to stop the AC.
