With people already reverse engineering the closed api of the Nest thermostat. It is possible for someone to create a plugin for Vera. This has me tempted to work on a plugin, but I do not have a Nest thermostat and not sure I want to spend the 250 dollars to tackle this project. If someone can convince me that the Nest thermostat is better than the Trane z-wave thermostat, I may go out and pick one up.

/forceon Garrett.. this is the thermostat you are looking for....  /forceoff

I want a reason to buy one as well so if there was a plug-in....

They're awesome T-Stats, but if you've got a Trane and have it tuned up (schedule, vacation-mode automation etc) then there's negligible financial reason to make the cutover to a Nest.

I have two Nests.  They look and operate a lot nicer than the Trane's, and they're a lot easier to config....  People who haven't transitioned to HA, or tuned their existing systems, will get a ton of gain from having these because they're incredibly simple to use.

In the beginning I missed the centralized control I had over my TStats with SQRemote, but now I don't really miss it at all....  I just fire up their app when I need to (which is rare).


NOTE: Their EUL specifically excludes the use of [undocumented] API's, presumably to protect their systems from rogue software, so use care with the hacks if you want to fly under the radar...

Looking at what others are using for the api, they are pretty much logging into the web interface and interacting with it. But to spend the 250 dollars for something that is already functional would be somewhat of a waste. I can take that 250 and spend it on a few other goodies.

I am very interested in getting a Nest plugin working. Could anyone give me some pointers for how I could port the python code linked above to luup?

If you're going to do it, it would pay to start by just getting the communications layer working, using pure Lua code (no Luup). 

You can make this into a Library (.lua file) that then gets included (require "nest.lua") into the counterpart Luup-based device files when you're ready.

It'll also be quicker to write-test-repeat this way, since you can just use a standard command line Lua interpreter on the platform of your choice (Windows, Mac, Linux, etc, etc)

The Lua programming manual is well documented at lua.org and loads of examples at lua-users.org.  When you're ready to integrate you can learn many of the luup constructs from the code over at code.mios.com (in particular, the thermostat plugins)

Awesome! Thanks for the quick reply.
I will see if I can figure it out.

When you figure it out, hook us all up :) . If you need me to test anything, I am willing.

It will be very cool to integrate the Nest.

The only issue is that is require a cable from Nest to the Valve. With the Trane this is not an issue as the communication is zwave.

Why is a cable needed when the Nest communicates via wifi? The problem seems to be the API, yet I thought I found some guy on the web had figured it out? O guess I need to do more digging.

There are examples of the api that has been reversed engineered on the Web. However there is no guarantee that it will change or they will prevent access.

Just wondering if anybody has a functioning plugin started for the Nest thermostat yet? I am still on a quest to find a high "cool factor" thermostat that I can integrate with my Vera 3.

No plugin has been developed for the nest yet.

Coming back to this topic, I was thinking of picking up the Nest again. Has anyone seen better performance from the Nest compared to the Trane? Does the Nest turn on when the temperature is above the set point temp? For example, if you have the nest set to 67, does it turn on when it is 68 or does it have about a degree of room? The one thing I hate about the Trane is that it always kicks in when it reaches past the set point. Does the nest also have some sort of fan cycle mode?

I have the first generation Nest with Software 3.03.

My nest indicated a room temperature of 67ºF. I set it up to 67º and the thermostat didn't call. I bumped it up to a setpoint of 68º and it immediately called.

Nest has either continuous or cycled fan control. There are a couple of features that delay the termination of a (cycled) fan call after the space is satisfied in cooling.

Let me know if I can be more help.
