webCoRE as PID controller?

#1

1) Give a description of the problem
I have HeatIt z-trm2fx thermostat to control floor heat. The problem is that I want to regulate the room temperature based on the theromostats floor sensor and room temperatur by using SmartThings Multipurpose.

2) What is the expected behaviour?
I want make webCoRE function as a PID controller based on two temperatures, floor and room. Does webCoRE have such a function or similar?

3) What is happening/not happening?
The thermostat has connection for room temperature sensor, but I want to avoid wires.

**4) Post a Green Snapshot of the piston![image|45x37]

5) Attach logs after turning logging level to Full

While you probably could do the math, a PID controller is likely overkill for a thermostat as temperatures don’t usually change that quickly. Also, since WebCoRE is event driven, it lends itself better to a bang-bang type controller. This would also limit the frequency of execution to only when necessary.

As long as you have access to the temperature readings and are able to control the heater, you can accomplish just about anything.
