Control4 & Nest Thermostat

Supa · December 2, 2011

Here is an anonymized, wrapped, and indented dump of a Nest status with an example 2 setpoints a days schedule, but you can have as many as you want. The rules for schedule setpoints is use 15min(*60sec) increments, keep them an hour or more apart from each other (excluding continuations), and in ascending seconds in each day array. You could probably break these rules and the Nest would internally honor your unaligned or shortly spaced times, but the schedule interfaces view/edit code on the web, mobile app, or the nest might behave erratically since they follow these rules for UI spatial reasons.

Chris at Chili Technologies in NYC wrote a Nest ruby plugin for the SiriProxy to read current temp and read/set target temp.

It's based on sniffing the iPhone app traffic and has some Siri say feedback, but its a great starting point for a C4 plugin.

Ok so here is a port of the Siri Nest code to a stand alone ruby script that uses Mac OSX to speak the results.

This is all working for me in Lion 10.7.2. You will need to install json and httparty extensions for ruby first

In terminal

sudo gem install httparty

create this file with your nest account email and password

#>these are just to enable a native osx text to speech say

#do a command line arg
ARGV.each do|ab|
  num = ab.to_i
  # change user/pass to your nest account
  mynest = Nest.new('your.account@nest', 'yourpassword')
  if num > 49 and num < 86
    mynest.set_temp("#{ab}")
  elsif ab == 'home'
    mynest.set_away_or_home('home')
  elsif ab == 'away'
    mynest.set_away_or_home('away')
  else
    mynest.get_status
  end
end

#set nest away
user$ nest away
Ok, I set the Nest to away.

#set nest home
user$ nest home
Ok, I set the Nest to home.

#set nest temp
user$ nest 69
Ok, I set the The Nest to 69 degrees. The current temperature is 67 degrees.

uh, Ryan you maybe want to hire this guy ^^^^^ or something?!

Heh. I've seen worse applicants, that's for sure...

looks like BGR picked it up:

Kahn · December 6, 2011

Well....understanding there is no relationship between C4 and Nest, looks as if the curious are finding there way! Speaking for myself, I would most eagerly welcome an unsupported (yet working) installation!

Heh. I've seen worse applicants, that's for sure...

Sadly I have got too much on my full time plate already this xmas to even consider notions like that. With 5000 users, 4000 mobiles, 1000 desktops, 500 switches, 200 waps, 100 mobile home servers, 50tb sans, 25 web sites, 15 buildings, 10 hs22v blade vmware hosts, 2 sonic e6500 uplinks doves, and iSeries in a pear tree. I do play on the side with what I find interesting new tech and code integrations between them, but I don't have any C4 gear.

Anyway back to the nest, the more difficult code to make the nest truly an open platform has yet be written. The schedule editor and finding a way to gather energy statistics from the device for custom visualizations.

RyanE · December 6, 2011

I've written a thermostat driver to a thermostat that was HTTP controlled.

It could probably be done for the Nest as well.

That said, it's more likely a dealer or driver partner will do it, as Control4 probably wouldn't without support from Nest.

RyanE

c44me · December 7, 2011

what about with support from your customers??? I'd gladly pay for this. I am sure others would as well in a heart beat.

well_armed · December 7, 2011

Awesome business model, making your business customers pay for 3rd party integration of devices.

RyanE · December 7, 2011

Control4 has provided (and will continue to provide) thousands of drivers for free.

You're criticizing because Control4 isn't currently making a driver for a 3rd-party product that was just released, that doesn't have an official API? A 3rd-party that could change the interface method (HTTP) at any time, so the driver could possibly just break for no apparent reason?

Wow, you're pretty fast on the trigger finger there, slick.

RyanE

well_armed · December 8, 2011

Don't get your pants in a bunch...it was more of a dig at the lack of developers who support C4 not C4's own driver development.

HouseLogix is currently writing a Control4 driver for the Nest Thermostat. Version 1 is about 75% complete. HouseLogix has developed drivers for a variety of devices and systems such as Lutron RadioRA 2.

awesome! please post when its available? have a target date?

CFUG · March 9, 2012

I'm going to change my tune about the Control4 stat. I have worked on an algorithm that uses CA relay T sensors to talk back to the thermostat. It's taken a few months of billing to see the savings in gas from the programming but it's there. More importantly, to the family, is better climate control where it is needed. The nice thing about all of this is freedom to place the CA relays anywhere they work best (out of drafty areas, next to seating, etc.).

Aside from Nest, I already own C4 stats and the programming tools are already there. No reason to move away from Control4.

Loki · March 10, 2012

Controlfouruserguy,

Can you please explain the algorithm you used?

Thanks,

Tony

CFUG · March 11, 2012

Not really an algo in the sense of something proprietary or black-box-ish. It depends on how screwed-up the airflow is around the wall stat and cold-air infiltration situation in the living space. T averaging was the worst of it since there is no utility within CHE to do this. Also, many conditions exist that could change or modify the "automatic" operation portion of the routine.

I didn't think anyone was interested when I opened a thread about this but I could post something on C4DYI.

Shoot me an email and we'll make this happen.
