Why thermostat is still heating after setpoint is reached?

Hello, enable debug mode and look at the values of pid_p, pid_i, pid_d and pid_e attributes. Their sum controls the PID output.

Hey @andriuskr , looks like your kp and/or ki values are too low, so it takes some time for PID controller to increase its output and heat more to compensate temperature drop. As ScratMan told, enable debug mode in Parameters and draw your pid_p, pid_i, pid_d values to see a proportion between them and their dynamics.
