Logs structured information about your home's Nest thermostats to third-party logging services like Datadog. You can use this to:
- Learn about your home's heating and cooling performance & patterns
- Experiment with energy efficiency techniques
You could also fork & extend it to control your heating & cooling appliances via the Nest API.
- Create a file called
auth.json(see below) - Run
node nest-logger.js
That's it! You should see your home data in your logging service within a few minutes.
Sample:
{
"nestRefreshToken": "1//jkasdfjasdfjasdf-adsfaskdfaksdf-5d-AB--jXjLuU0S8XjDjf",
"datadogApiKey": " 4f089ce1054244157e53d92760cec66"
}Your Datadog API key can be generated via the website (docs)
(instructions & code copied from homebridge-nest README)
The "refreshToken" is a code provided by Google when you log into your account, and we provide an easy-to-use tool to obtain it.
Just run: node nest-login.js and follow the instructions on the screen.
You'll be prompted to navigate to a URL in your browser, log into Google, and copy and paste a code from your browser into the login tool. You'll then be provided with the "refreshToken" to add to config.json. The refresh token is a random string
of letters and numbers - it does not begin with, end with, or contain any spaces. Please make sure you copy and paste it exactly as shown, or it will not work.
When you run it, you should see something like this:
{"instance":0.9169385740067195,"level":"info","message":"starting up","service":"nest-logger"}

{"instance":0.9169385740067195,"level":"info","service":"nest-logger"}Then it might take a few seconds or a few minutes (I don't know why) before you see this:
