Apologies if my description was misleading it wasn't on purpose I just didn't understand as I thought I did. That is a great help so seems like it is definitely possible so now I just need to get on with trying to make it work. Thank you again I really like the idea but will be on a very steep learning curve!
@Puneit-Thukral https://www.agafixspares.com/store/index.php?main_page=product_info&products_id=1007 this is the thermostat I am looking to replace/automate.
So I am totally new to all of this but am keen to learn and like a project to be the way I learn.
I have an oil vaporising Aga, they are super simple. Essentially they have a wick that burns oil and heats the Aga. The oil flow is controlled by an electric regulator and is either high fire, or low fire. The default is low fire, but when the thermostat detects that the temperature has dropped it sends a signal to the regulator to turn to high fire, when the temperature is reached it switches back to low fire and so on maintaining the temperature range.
This is all done with a manual dial you turn up and down on the thermostat. The Aga takes hours to heat up so essentially you just leave it at the same temperature all the time.
What I would like to be able to do is remotely change the thermostat. For example, we are going away for the weekend so turn the temperature down to save oil. But when coming home don't want to wait 5 hours to be able to cook, so I want to be able to send a signal to change back to cooking temperature before travelling back and moving the dial.
I am sure this is not impossible but as a total novice also wanted a steer on where to start?
Thanks
