Re: [PLUG] Home automation

The 3m thermostats do have a published API.  I had documented it a good part of it ( but am getting ready to take it down and have a volunteer rehost it.

If you want a traditional thermostat that also has an API, the
3M-Filtrete 3M-30 and 3M-50 (corresponding to the Radio Thermostat
Company of America CT-30 and CT-50) has a nice REST API with json

They run ~$100 for the *-30 and ~$200 for the *-50.  Main difference
being humidity sensors on the -50 and a section of alphanumeric
display on the LCD you can set via the API.

I have the -30 and most of my integration so far has just been data
collection.  Occasionaly I change the setpoint via the iOS or Android
app.  When I get around to it, I want to add auto-away mode based on
the security system and other such sexiness.

There seems to be something wrong with your exterior thermostat.  It's constantly saying 80F.

Also, does the *-30 have an API?  How does it connect to the network?  The *-50 after some research is the only model with a wifi module.
