I want to control a thermal mixing valve with temperature set point set from Homeseer.
The valve is opened or closed with 24V ac pulses, so I was thinking along the lines of an Arduino with 2 relay outputs and a 1-wire temperature sensor. Control should be fairly easy to do with the Arduino. I would like to be able to set the temperature from Homeseer, but the Arduino should be able to run the temperature control without a continuous connection to HS, so it still works when Homeseer has crashed.
Initially I thought that this plugin might let me do that, but it looks as if it just uses the Arduino as an I/O extension and needs to be connected continually.
Can you confirm if this is the case?
