Nest Device Type for SmartThings
/**
* Nest Direct
*
* Author: dianoga7@3dgo.net
* Date: 2013-07-18
* Code: https://gist.github.com/Dianoga/6055918
*
* INSTALLATION
* =========================================
* 1) Create a new device type (https://graph.api.smartthings.com/ide/devices)
* Name: Nest
* Author: dianoga7@3dgo.net
* Capabilities:
* Polling
* Relative Humidity Measurement
* Thermostat
* Custom Attributes:
* presence
* Custom Commands:
* away
* present
* setPresence
*
* 2) Create a new device (https://graph.api.smartthings.com/device/list)
* Name: Your Choice
* Device Network Id: Your Choice
* Type: Nest (should be the last option)
* Location: Choose the correct location
* Hub/Group: Leave blank
*
* 3) Update device preferences
* Click on the new device to see the details.
* Click the edit button next to Preferences
* Fill in your information.
* To find your serial number, login to http://home.nest.com. Click on the thermostat
* you want to control. Under settings, go to Technical Info. Your serial number is
* the second item.
*
* 4) That's it, you're done.

Question on this (from a noob) -- does the tile show the temperature it polls from the Nest service?

how long does the polling take?

Answers: Yes, the tile shows the temperature that the Nest reported on the last poll.
Initial polling takes a minute or two, I found that if I went into the Activity feed, I could get it update the tile faster.

Dianoga: Just noticed that your weather method uses a hardcoded zip code for IA.
I modified my version to create a new setting called zip and then used that setting in the API call.
Probably worth a mod, I didn't think it warranted a fork.

Great work!

Question: How does one handle the case where 2 people live in the house, each having a SmartThings presence sensor (iPhone)? If one person leaves and the other remains - who 'wins' the away/present vote? Is this handled in the current release?

Thanks in advance!

Question: Is it possible to use '+' and '-' tiles for the temperature instead of the slider? If so, how would this be written? The current way of altering the setpoint is the slider, and this is not really smooth. When I let go of the slider it ends up either a few degrees higher or lower then the temp I actually want, because of my big fingers. Also, the slider is hard to "grab" in both the iPhone and Android. (I tried but i'm kind of a noob to this language as I just got my hub a few days ago)

Great work, by the way, integrates with nest pretty much seamlessly.

Hey pickerin: I followed all the steps but the new devices in the app doesn't seem to be updating with any of the data from my Nest. Any thoughts?

Nevermind, I just needed to adjust the code for the Device Type a bit from how I had it. Thanks

dianoga - question:
I'm with you on steps 1 and 2 - but where do you do #3 at in the instructions?

Question, when I copy and paste it I get the following error.
