Thermostat piston that works

[daniionescubrasov]

Hi.

I just only want to share share a simple thermostat piston that works and is based only on what’s inside the box of the SmartThings kit. It turns on the heat but only when you are at home. Otherwise it turns it off. Which is enough for most of the people…

Enjoy.

Post update: now with anti freeze protection at 16 degrees, when you are away.

Post Edit: I discovered that the above piston only partially work. (Only the second If with the 19 degrees was applied.)
So I split the piston on two pistons like bellow. Now they both worked. How can I gather the bellow pistons into one to work?

Thank you.
