How to Connect Nest Thermostat

[Shady Hamilton 11]

Dear All,

 

This is my First topic here, i am moving from Vera to Fibaro, I always wondered which one is the better controller, so I have to have hands on i guess to know which one is the better...

My first issue is my Nest Thermostat controllers, i have two of them, i read around the forum that there used to be a plug in but it is stopped by Fibaro to be updated or something, and I contacted Fibaro support, they said they are not going to work on the Nest plug-in because they are working on their own thermostat, so they don't want to support Nest in a way....

 

so my question is, since Nest is one of the most popular thermostat controller, did anybody find a way to connect Nest thermstat to Fibaro HC2 please?

 

Many thanks,

Shady

But only one works

 

this is probably due to oauth certification, if you install more than one QA, each of them will try to auth itself, and probably the last one only will work. To use as multi thermostate one need project per thermostate (actually bad idea, because each need separate ggl account) or (and that's the way to go) device controller Quick App, which do the oauth and create multiple slave Quick App Heat Thermostates

We shall offer some beers for the ones to close this neverending story....

 

PS: offer is not valid for fibaro team, as they have ignored their customers for years in a row... (strange to see that nowadays, normally they should be happy to welcome AND SOLVE customers' requests).

Turning this into a Virtual Device for HC2 is the next step to get Nest working again.

 

Update

I've managed to create a first proof-of-concept scene which reads the Nest settings using the official API based off

Now it should be pretty easy to create a few virtual devices around it to control and display the Nest thermostatt settings.

Nice work, mooi werk. 
 

Did you pay 5€ to access the api?

that is a Dutch question ?

 

(But you need to pay to get the right credentials)

I've just pushed my proof-of-concept code to github. If you're brave enough you can check it out over here.

What currently works is setting (and reading) the temperature setpoint, reading the ambient temperature and humidity sensor.

 

UPDATE

Setting Nest thermostat mode through the virtual device now works as well.

Thanks Marc. I have a HC2 and Nest Thermostat at the office. I will give it a try monday.

Hi @marcfonteijn, did you already test some kind of automation? Example ... if no one is at home lower down the temperature or vice versa?

Not yet. That would be the next. Shouldn't be too hard though. Just create a new scene that monitors the nest status and triggers certain actions based on that. Probably involves some use of the heating panel. But that's all stuff that has been figured out by someone already

I'm stuck at the authorisations and tokens for the nest api, the CURL (Windows 10) doesn't work.....

For the authorization code you need to follow the steps here.

This means opening the URL in your browser.  If done correctly you'll be guided through a few steps. The authorization code will be in your browsers URL to which you have been redirected to after finishing the final step. It's very easy to overlook that the authorization code is hidden in there.

 

And then once you have the authorization code you can get the refresh code from here:

? And do you have the right OAuth client ID set there?

[SmartHomeEddy 1,005]

Yes, I created, after searching for the right buttons, a project and got back a Client ID, Project id, Client secret and API key. 

 

If I manually copy the Client ID to the Device Access Console, I get an different error:

What a *abuse* setup procedure. Look like Google doesn't want people to use it.
