Credits: github @gboudreau for the initial Nest APIs discovery
You can now download the code at
http://www.ecomatiqhomes.com/storeP.S. Technical support packages are also available.
Setup time: about 15-25 minutes depending on your ST skills.
Some technical skills & manual tasks are required to setup your Nest devices under ST as the Nest Web APIs used are not the "official" ones and don't have an oAuth flow (see LOGIN INFO For NEst or Google Account users below).
-
a) [Nest] Your Nest products fully operational and connected to Nest Home via the internet
Please note that all Nest thermostat devices are supported except the Nest thermostat E in the UK (with the heat link). Next Cams & Door Bells, and the Nest Secure Alarm are not supported.
-
b) [Nest] Nest setup completed for your Nest devices under your Nest Primary account (don't use any Nest secondary accounts for the integation with SmartThings!!)
-
c) [ST CLASSIC APP] The installation must proceed with the SmartThings classic mobile app, so you have to download it first from your appStore. This is required as any custom DTHs can only be instantiated or created via the ST classic mobile app
However, after creating the devices under SmartThings, you can return to the new Samsung Connect app if you prefer as both apps (ST classic, STSC) can run in parallel without any issues.
- d) [ST CLASSIC APP] Location set for your ST account under the ST classic mobile app
Under the ST classic mobile app, click on the 3-horizontal lines- "hamburger"- menu in the upper left corner, and then the "gear'" icon to review your location and save it. You can refer to the SmartThings' documentation for more details.
https://support.smartthings.com/hc/en-us/articles/205956850-How-to-edit-Location-settings
- e) [ST IDE] Determine your shard, please consult this thread:
Or the SmartThings documentation here for more details:
http://docs.smartthings.com/en/latest/publishing/index.html#ensure-proper-location
If you are on a different shard, you need to change the links below for your right shard. As an example, in North America,
replace https://graph.api.smartthings.com/ide/devices by https://graph-na02-useast1.api.smartthings.com
Or use https://consigliere-regional.api.smartthings.com/ to point to the right shard.
-
Once you log in to your Nest account as described in the steps below, please keep the connection active to avoid any disconnect in ST (i.e., do not log off, but you can close your browser and even turn off your desktop/mobile), and don't change your Nest account password or 2FA settings.
-
Google recently introduced reCAPTCHA when logging to Nest. That means username and password cannot be used directly any more. Instead, you have to obtain
user_idandaccess_tokenfor your account by logging in manually. -
For some visual guidelines, refer to screenshots in the link below
7 Steps for Nest users who have NOT migrated to a Google account:
-
[Chrome] To do that, open
developer toolsin your Chrome browser, switch to theNetworktab, -
[Chrome] Hit
preserve Logsin the Network tab -
[Chrome] Log in to home.nest.com and look for the request similar to https://home.nest.com/session?_=157XXXXXX.
-
[Chrome] You can use the filter "session" to get the exact info needed.
-
[Chrome] You will find
user_idandaccess_tokenin the response to the request. -
[Chrome->ST] MyNestManagerV2- AppSettings section: Copy over the Nest login information to the corresponding nest_* fields in App Settings (ST IDE) for MyNextManagerV2, refer to step 2g) below at https://github.com/yracine/device-type-myNext/blob/master/README.md#2-create-a-new-smartapp-mynextmanagerv2.
FYI,the login info for Nest account users looks like the following:
nest_user_id=4783742 nest_access_token=b.4783742.xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- [ST IDE] MyNestManagerV2- AppSettings section: After copying and pasting the login info, press "update" at the bottom of the ST IDE to save your variables.
Do not copy the double quotes in the ST IDE variables.
Notes:
-
If you lose your auth tokens, then you'd need to redo the steps above and copy over the new nest access_token back to the ST IDE. You can then reset the Nest connection by executing MyNextManagerV2 under Automation/Smartapps in the ST classic mobile app by pressing "Next" till "Save").
-
You don't need to re-install the devices, just reset the Nest connection.
Notes:
-
Once you log in to your Nest account as described in the steps below, please keep the connection active to avoid any disconnect in ST (i.e., do not log off, but you can close your browser and even turn off your desktop/mobile), and don't change your Google account password or 2FA settings.
-
If you lose your auth tokens, then you'd need to redo the steps below and copy over the new google cookie and issue_token_url back to the ST IDE. You can then reset the Nest connection by executing MyNextManagerV2 under Automation/Smartapps in the ST classic mobile app by pressing "Next" till "Save").
-
You don't need to re-install the devices, just reset the Nest connection.
13 Steps for users who have migrated to a Google account:
Similar as the Nest account user, open developer tools in your Chrome browser,switch to the Network tab, hit preserve Logs.
For some visual guidelines, refer to screenshots in the link below
The values of issue_token and cookie are specific to your Google Account. To get them, follow these steps (only needs to be done once, as long as you stay logged into your Google Account).
- [Chrome] Open a Chrome browser tab in Incognito Mode (or clear your cache).
- [Chrome] Open Developer Tools (View/Developer/Developer Tools).
- [Chrome] Click on 'Network' tab.
- [Chrome] Make sure 'Preserve Log' is checked.
- [Chrome] In the 'Filter' box, enter
issueToken - [Chrome] Go to
home.nest.com, and click 'Sign in with Google'. Log into your account. - [Chrome] One network call (beginning with
iframerpc) will appear in the Dev Tools window. Click on it. - [Chrome] In the Headers tab, under General, copy the entire
Request URL(beginning withhttps://accounts.google.com, ending withnest.com). This is your"google_issue_token"in the App Settings section of MyNextManagerV2 (ST IDE).Refer to https://github.com/yracine/device-type-myNext/blob/master/README.md#2-create-a-new-smartapp-mynextmanagerv2. - [Chrome] In the 'Filter' box, enter
oauth2/iframe - [Chrome] Several network calls will appear in the Dev Tools window. Click on the last
iframecall. 11.[Chrome] In the Headers tab, under Request Headers, copy the entirecookie(usually it starts withOCAK=...or orSID=...or with other values - include the whole string which is several lines long and has many field/value pairs - do not include thecookie:name). You can copy it in your preferred editor to split it in multiple fields of similar length. Depending on your cookie's length, you may have to split it into 3-6 fields in the IDE. - [Chrome->ST IDE] MyNestManagerV2- AppSettings section: This is your "cookie" in the Settings section of the MyNextManagerV2 smartapp in the ST IDE. In order to copy the whole cookie, you'd need to split it into different google_cookie_p* fields in the Settings section as the SmartThings platform doesn't support long text variables. If the text is too long, SmartThings will report an exception (500) when you try to save a too long cookie field. Refer to step 2g) below at https://github.com/yracine/device-type-myNext/blob/master/README.md#2-create-a-new-smartapp-mynextmanagerv2.
- [Chrome->ST IDE] MyNestManagerV2- AppSettings section: Make sure that all your google_cookie_p* fields contain the whole cookie from Google.
- [ST IDE] MyNestManagerV2- AppSettings section: After copying and pasting the login info, press "update" at the bottom of the ST IDE to save your variables.
1) Depending on your contribution, create one or multiple Device Handler Type(s) - DTH for My NextTstatV2 or MyNextAlarmV2 or NextSensorV2
For each device (My NextTstatV2, My NextAlarmV2, My NextSensorV2),

Following your financial contribution at www.ecomatiqhomes.com/store, the code has been sent to you by Sellfy via your paypal verified email address.
e) [ST IDE] Hit the create button at the bottom
f) [ST IDE] Hit the "publish/for me" button at the top right corner (in the code window)
a) Go to https://graph.api.smartthings.com/ide/apps (or whatever your shard is, and click on My Smartapps in the IDE's top menu)
b) [ST IDE] Hit the "+New SmartApp" at the top right corner
c) [ST IDE] Hit the "From Code" tab on the left corner
d) [ST IDE] Copy and paste the code from the corresponding txt file in the zip
Following your financial contribution at www.ecomatiqhomes.com/store, the code has been sent to you by Sellfy via your paypal verified email address.
e) [ST IDE] Hit the create button at the bottom
f) [ST IDE] Make sure that "enable OAuth" in Smartapp is active
- Goto app settings (top right corner, click on it)
- Click on Oauth (middle of the page), and enable OAuth in Smart app
- Hit "Update" at the bottom back to the code window, and hit the "publish/for me" button at the top right corner
g) [ST IDE] Click on App Settings and copy the required login info (Google or Nest account) whether you're still a Nest account user or a Google Account user.
h) [ST IDE] Click on the update button at the bottom to save your login information from Nest/Google.
If the instructions above are not clear enough, you can refer to the troubleshooting section below with some pictures:
[ST IDE] Go to the IDE in order to watch for any exceptions/errors in the logs.
https://graph.api.smartthings.com/ide/logs (or whatever your shard is, under Live Logging in the IDE)
You can click at the top of the window on the smartapp name to filter the logs.
[ST CLASSIC APP] Click on the Smartapps link in the upper section of the following Marketspace screen (last icon in the bottom menu), and then Smartapps/MyApps (last item in the list).
[ST CLASSIC APP] To execute MyNextManagerV2, find the MyNextManagerV2 smartapp under MarketSpace>Smartapps>MyApps, My NextManagerV2 should be in the middle of the list. To start the Authentication with Nest, press Next on the first page.
[ST IDE] Check the logs for any installation errors. Your login info may not have been copied correctly in the MyNextManagerV2's App Settings section.
As a reminder for the Google account users, in order to copy the whole cookie, you'd need to split it into different fields in AppSettings as the SmartThings platform doesn't support long text variables.
N.B. If you have any errors:
[ST CLASSIC APP] If you get a blank screen after pressing 'Next or you get the following error: "Error - bad state' or 'Java.lang.NullPointerException: Cannot get property 'accessToken' on null object" in the IDE', you'd need to enable oAuth as specified in step 2f) above.
[ST CLASSIC APP] At the end of the authorization flow, if you have the following error message: "Unexpected error" even if you press several times, this probably means that you have not "saved & published" one of the Device Handler Types (MyNextTstatV2,MyNextAlarmV2,MyNextSensorV2) under the right shard. Refer to the prerequisites & step 1 for more details.
[ST CLASSIC APP] Also, depending on the ST platform status, you may have to press "Save" several times if you have the following error message: "Error processing your request - please try again". This is due to some ST platform timeouts due to rate limiting.
After about 1 minute, You should see your newly Next devices instantiated under:
[ST IDE] a) https://graph.api.smartthings.com/device/list (or whatever your shard is and click on My Devices in the IDE's top menu)
And also
[ST CLASSIC APP] b) Under the ST classic mobile app, under MyHome/Things (main menu at the bottom of the screen).
[ST CLASSIC APP] If the fields are blank, you may have to hit the 'refresh' button on your newly created Next devices as the smartThings UI is not always responsive.
a) [ST IDE] Go to https://graph.api.smartthings.com/device/list (or whatever your shard is and click on My Devices in the IDE's top menu)
b) [ST IDE] Click on the Next Devices that you just created
c) [ST IDE] Click on Preferences (edit)
N.B. [ST CLASSIC APP] You can also edit the preferences under Things/Your Device/Edit Device using the app.
You only need to edit the following parameters
[ST IDE] (a) when needed, set to true to get more tracing (no spaces) (b) logFilter:1..5 Values=[Level 1=ERROR only,2=<Level 1+WARNING>,3=<2+INFO>,4=<3+DEBUG>,5=<4+TRACE>]
P.S. Don't enter any values for the internal ID or the structure ID as those values are provided by the Service Manager during the authentification flow

d) Zoning smartapps
/****************************************************
The following zoned Heating/cooling smartapps have many features to leverage your Nest Thermostat.
- User friendly Dashboard and workflow pages for easier setup (i.e. Dashboard->GeneralSetup->RoomsSetup->ZonesSetup->SchedulesSetup-> NotificationSettings).
- Flexible schedule definition: you can define up to 12 schedules for your zones (mornings, weekdays, evenings, nights, weekends, etc.)
- Remote Sensors: choice of temp calculation method (Average, Median, Minimum, Maximum, Heat/Min-Cool/Max) based on all room temp sensors inside the zone so that your heat/cool settings are adjusted at the main thermostat even if your rooms are far away. The average calculation is similar to the ecobee3's follow me feature with its remote sensors.
- For each schedule, ST users can define the start & end times, the thermostat's heating/cooling setpoints (or climates for ecobee), the max temp adjustment based on the chosen calculation method (avg, median, min, max, etc.)
- You can set your schedules to run only for some routines/ST hello modes (ex. 'Away', 'Home', 'Night', or your own customized ones )
- For each schedule, you can assign the included zone(s) according to your own requirements (ex. Upstairs bedrooms, 1st level, basement, etc)
- You can define up to 8 zones for your home which can include up to 16 rooms
- Ability to set your smart thermostat to 'Away' or 'Present' based on all rooms' motion sensors
- Ability to set the thermostat's fanMode ('on', 'auto', 'circulate') during a specific schedule
- Ability to trigger the thermostat's fan based on some indoor temp differential. The temp differential can be customized for each schedule.
- Ability to adjust your main thermostat's settings (every 5 minutes) based on an outdoor temp sensor (optional)
- and many more features...
