Smart Thermostat

Former Member

Hi,

 

Do you think it would be possible to add the sensors and controls to the Raspi for it work as a smart thermostat.

Like the Nest http://www.nest.com/ or ecobee http://www.ecobee.com/solutions/home/

I obviously would require a thermostat and control switch to turn the central heating on and off, and possibly a motion detector to monitor when people leave/enter their home.

Are these sort of items available to connect to the GPIO ?

 

Then the really hard bit for me, I would need to create the software to control it all (but that's why I ordered a Raspi, to challenge myself).

Although some might think it's easy, I haven't done any real programming in 20 odd years.

 

Cheers.

  • Yes, that is in fact possible.

     

    I sell exacty the expansion boards that make this possible.

     

    You will need the RPI_SERIAL, the I2C_TEMP (possibly not yet up in the store), and I2C_RELAY.

     

    If you want to do PIR detetion I suggest you add an I2C_DIO.

     

    I'll help you for sure so that you can control the relay from the commandline and read out the sensors into a file. (the core of your smart thermostat will then consist of reading those files, or executing the program to control the relay.)
