I moved to a new house and I would like to install my Nest thermostat. The issue is that I cannot run new cables from the HVAC system to my house. Hence, I'm exploring the possibility of a wireless solution between my Nest and the HVAC.
They are already some wireless thermostat solutions like this one.
The principles are very simple: you connect to the HVAC a receiver, install the thermostat in your house and the HVAC commands will be sent wirelessly.
I would like to do a similar system for my Nest. The concept would be the following:
- Connect the current Nest thermostat to a Arduino board
- The Nest will execute the various command signals as usual: Heating on or off
- The Arduino product will read the commands sent by the Nest: it's a basic on/off contact with 2 wires.
- Once received, the Arduino will send over wifi the commands to a similar Arduino control board connected to the HVAC system
- The Arduino control board will receive the commands from wifi and will send the inputs to the HVAC system through the 2 wires
Do you think my idea is feasible? And if yes, do you know where I can find people willing to build it for me? I would of course pay for this!
