You can now download the code at
http://www.ecomatiqhomes.com/hubitatstoreP.S. Technical support packages are also available.
Setup time: about 15-25 minutes depending on your Hubitat skills.
Some technical skills & manual tasks are required to setup your Nest devices under Hubitat 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 hubitat!!)
-
Once you log in to your Nest account as described in the steps below, please keep the connection active to avoid any disconnect in Hubitat (i.e., do not log off, but you can close your browser and even turn off your desktop/mobile), don't change your Nest account password or 2FA settings, and do not re-login to keep your cookie valid.
-
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->IDE] MyNestManager- Copy over the Nest login information to the corresponding nest_* fields in the header (IDE) for MyNextManager, refer to step 2g) below at https://github.com/yracine/device-type-myNext/blob/master/README.md#2-create-a-new-smartapp-mynextmanagerv2.
In the header (code) section of MyNextManager, you will see "INSERT THE NEST LOGIN INFORMATION BELOW".
FYI,the login info for Nest account users looks like the following (your Nest user id will be different):
nest_user_id=4783742 nest_access_token=b.4783742.xXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
[Hubitat IDE] MyNestManager- header (code) section: After copying and pasting the login info, press "save" to save the code with your Nest login variables. Don't insert anything in the google section. Do not copy the double quotes from the nest login information in the 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 Hubitat IDE. You can then reset the Nest connection by executing MyNextManager under Automation/Smartapps in the Samsung connect app by pressing "Next" till "Done").
-
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 Hubitat (i.e., do not log off, but you can close your browser and even turn off your desktop/mobile), don't change your Nest account password or 2FA settings, and do not re-login to keep your cookie valid.
-
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 Hubitat IDE. You can then reset the Nest connection by executing MyNextManager by pressing "Next" till "Done").
-
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_url".
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. - [Chrome] In the Headers tab, under Request Headers, copy the entire
cookie(usually it starts withOCAK=...orSID=...orSMSV=...or with other values - include the whole string which is several lines long and has many field/value pairs - do not include thecookie:name). This google "cookie" needs to be copied over in the code (header) section of the MyNextManager smartapp under the instructions saying 'INSERT GOOGLE LOGIN INFO BELOW'. See https://github.com/yracine/device-type-myNext/blob/master/README.md#2-create-a-new-smartapp-mynextmanagerv2. - [Chrome->IDE] MyNestManager- Make sure that the whole cookie from Google is contained in google_cookiep1. There is no need to split the cookie anymore Please make sure to avoid inserting extra spaces or any other characters when you copy the google cookie as Google will not accept it and the list of devices will be empty.
- [Hubitat IDE] MyNestManager header: After copying and pasting the login info in the header, press "save" to save your global variables.
a) go to http://192.168.xx.xx/app/list (insert your own hub's ip address)
b) click on MyNextManager in the list of smartapps.
c) Copy the nest user and auth token into the header as global variables.
Do not copy the doubleotes in the global variables
1) Depending on your contribution, create one or multiple device driver(s) - DTH for My NextTstat or MyNextAlarm (for Protects) or NextSensor
For each device (My NextTstat, My NextAlarm, My NextSensor),
a) Create a new device driver
go to http://192.168.xx.xx/driver/list (insert your own hub's IP address)
b) Hit the "+New Driver" at the top right corner
c) Copy and paste the code from the corresponding txt file in the zip
d) Hit the save button on the right inside of the screen
go to http://192.168.xx.xx/app/list (insert your own hub's IP address)
a) Hit the "+New App" at the top right corner
b) Copy and paste the code from the corresponding txt file in the zip
c) Hit the save button on the right inside of the screen
d) Make sure to enable OAuth in "Apps Code" is active (click oAuth in the upper right corner)
- Hit "Update" at the bottom
e) Copy the login information from Nest or Google under the right global variables (see instructions above)
f) Click on the "save" button at the right corner to save your login information from Nest/Google as global variables
If the instructions above are not clear enough, you can refer to the troubleshooting section below with some pictures:
http://192.168.xx.xx/installedapp/list (insert your own hub's IP address)
a) Click on "Add User app" in the right corner of the window
[Hubitat IDE] Check the logs for any installation errors. Your login info may not have been copied correctly in the MyNextManagerV2's App Settings section.
http://192.168.xx.xx/logs (insert your own hub's IP address)
N.B. If you have any errors:
If you get a blank screen after pressing 'Next or you get the following error: "Java.lang.NullPointerException: Cannot execute null+1"' on null object" in the IDE', you'd need to enable oAuth as specified in step 2d) above.
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" one of the drivers (MyNextTstat, MyNextAlarm, MyNextSensor). Refer to step 1 for more details.
After about 1 minute, You should see your newly Next devices instantiated under:
[Hubitat IDE] go to http://192.168.xx.xx/device/list (insert your own hub's IP address)
a) Click on the My Next devices that you just created
http://192.168.xx.xx/device/edit/"device number" (Device number can vary from one location to the next)
b) Edit the preferences in the middle section of the screen)
You only need to edit the following parameters
(a) <trace> 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>]
And, press "save preferences" at the end.
N.B. The detailed logging will be set for the next 15 minutes only (deactivated after to avoid performance issues)
