Thermostat and two heating sources

I was a long time insteon/ISY user and have moved to smarthings and never looked back.
I heat my house with oil and pellets. What I would like to do is round robin my heating sources.
Lets say oil now then pellets next…
I will be using a Enerwave Z-Wave PLUS dual relay module to control the call for the heat sources. And for sensing temp i will be using a Aeon multisensor hardware.

  1. I would like to be able to set a swing for each heating source
  2. Can a device handler be made to interact with web core so it can represent a thermostat? I would not like to make it easy to change the temp. ( wife needs to able to use it)
