homebridge-eveatmo

This is a homebridge plugin which lets you integrate your non-HomeKit Netatmo Weatherstation and Indoor Air Quality monitor into HomeKit.

Whilst the original homebridge-netatmo-plugin goes a mostly HomeKit-standard approach (predefined services, characteristics, ...), this plugin tries to mimic the Elgato Eve devices as close as possible.

:rotating_light: Warning

Since Netatmo announced a change to their authentification-policies it was also necessary to update this plugin's authentication-mechanism. From 1.0.0 it is not recommended to use username/password auth anymore although it is technically still supported in the latest release (1.1.0).

You need to generate an OAuth refresh_token on your app's page at dev.netatmo.com instead. For more details see the instructions below or take a look at this issue: https://github.com/skrollme/homebridge-eveatmo/issues/62. Since some users have still unidentified problems with the new authentication-mechanism you can keep using the username/password auth, but it can be shut down by netatmo at any time.

Configuration

Because this plugin's base was taken from homebridge-netatmo (see above) you can adapt its config. Just use the plattform-code "eveatmo" and remove "ttl" and/or the other "refresh_" properties for the beginning.

You can also configure this plugin via ConfigUI-X's settings feature.

"platforms": [
        {
            "platform": "eveatmo",
            "name": "eveatmo platform",
            "extra_co2_sensor": false,
            "co2_alert_threshold": 1000,
            "weatherstation": true,
            "airquality": false,
            "ttl": 540,
            "log_info_msg", true,
            "auth": {
    	        "client_id": "XXXXX Create at https://dev.netatmo.com/",
                "client_secret": "XXXXX Create at https://dev.netatmo.com/",
                "refresh_token": "a valid refresh token for the given client_id",
                "grant_type": "refresh_token"
                
                ... or if you use password-grant ...
                
                "client_id": "XXXXX Create at https://dev.netatmo.com/",
                "client_secret": "XXXXX Create at https://dev.netatmo.com/",
                "username": "your netatmo account's mail-address",
                "password": "your netatmo account's password",
                "grant_type": "password"
            }
        }
    ],

• weatherstation Enables support for Netatmo's WeatherStation. Default value is true
• airquality Enables support for Netatmo's Indoor Air Quality monitor. Default value is false
• extra_aq_sensor: (optional) Adds an extra AirQuality sensor which is available via Apple's stock Home.app, reporting CO2 level. Default value is true
• extra_co2_sensor: (optional) Adds an extra CO2 sensor which is available via Apple's stock Home.app, too. Default value is false
• co2_alert_threshold (optional): Sets the co2-level [ppm] at which the sensors switch to alert-state
• ttl: (optional) Seconds between two Netatmo API polls. Lower is not neccessarily better! The weatherstation itself collects one value per 5minutes, so going below 300s makes no sense. Default value is 540 (=9min)
• auth: Credentials for the Netatmo API (see below)
• log_info_msg: (optional) Outputs log messages with loglevel set to info. Default value is true
• module_suffix: (optional) If this is set, the Netatmo's devicename will not be prepended to the modulename. Instead this config-value will be appended - with a space - to the module name

Control Accessories by device ID

Controlling devices can be done on a finer level by id. The id of a netatmo device or module basically is it's mac address.

In order to include or exclude a specific device, the corresponding id can be included in a whitelist resp. blacklist.

If the whitelist contains at least one entry, all other ids will be excluded.

Netatmo API authentication

There are two methods to authenticate against the Netatmo API, but first 4 steps are always the same:

1. Register at http://dev.netatmo.com as a developer
2. After successful registration create your own app by using the menu entry "CREATE AN APP"
3. On the following page, enter a name for your app. Any name can be chosen. All other fields of the form (like callback_url, etc.) can be left blank.
4. After successfully submitting the form the overview page of your app should show client_id and client_secret.

"refresh_token" grant

This one is recommended by Netatmo because it is more secure since you do not have to store your username and password in homebridge's config file. The downside is, that it is a little bit less stable, especially when homebridge is not running constantly. This is because the plugin always gets a short-lived token to fetch data for some time. When the token expires, the plugin has to fetch a new one from the API.

5. Do an initial auth with the newly created app via the "Token generator" on your app's page https://dev.netatmo.com/apps/ to get a refresh_token
6. Add the client_id, the client_secret and the refresh_token to the config's auth-section
7. The plugin will use the refresh_token from the config to retrieve and refresh auth_tokens. It will also store newly retrieved tokens in a file (netatmo-token.js) in your homebridge config directory. If you delete the netatmo-token.js file, you may have to regenerate a new refresh_token like in step 5) if your initial refresh_token (from the config.json) already has expired

"password" grant

This one is my preferred method, because in a single-user scenario and a most likely "at home and self-hosted"-setup it is totally fine for me. Netatmo deprecated this method but it is usable in cases where the user (here: homebridge) and the account (where the weatherstation is linked to) are the same. Since this is the normal use-case for this homebridge-plugin I use this as long it is possible.

5. Add the client_id, the client_secret, the username (your account email) and the password (your account password) to the config's auth-section

Retrieve client_id, client_secret and refresh_token

Siri Voice Commands

Here are sample English voice commands:

• How cool is it in the ROOM NAME?
• How warm is it in the ROOM NAME?
• How humid is it in the ROOM NAME?
• What's the temperature in my ROOM NAME?
• What's the humidity in my ROOM NAME?
• What's the air quality in my ROOM NAME?
• What's the CO2 level in my ROOM NAME?
• What's the carbon dioxide level in my ROOM NAME?

Siri understands variations of each command:

• What's the temperature ROOM NAME?
• What's the temperature in ROOM NAME?
• What's the temperature in my ROOM NAME?
• What's the temperature in the ROOM NAME?
• What's the temperature down in my ROOM NAME?
• What's the temperature down in the ROOM NAME?

Siri voice commands may vary by language. Since this plugin tries to mimic the Elgato Eve devices, you can search the Eve blog for articles listing voice commands in your language.

Thanks and disclaimer

This plugin's basic structure and most of its basic code is a fork (ok, lets say "copy") of homebridge-netatmo. So big thanks to @planetk and all the other contributors of this project.

Also big thanks to @gomfunkel and @simont77 for this gist and its fork, @KhaosT for this gist, @mplewis for this gist and @0ff for this (almost) working Eve Weather imitating homebridge-plugin and once again special thanks to @simont77 for his endurance in digging deeper in Eve's custom characteristics and its protocols.

Thanks go also to the following direct contributors:

• @jason-klein (https://github.com/skrollme/homebridge-eveatmo/pull/28)
• @lisanet (https://github.com/skrollme/homebridge-eveatmo/pull/36)
• @foliveira (https://github.com/skrollme/homebridge-eveatmo/pull/52)
• @RyanHS7VM (https://github.com/skrollme/homebridge-eveatmo/pull/54)
• @smhex (https://github.com/skrollme/homebridge-eveatmo/pull/65)
• @Tellicious (https://github.com/skrollme/homebridge-eveatmo/pull/76)

Since Netatmo announced some changes on what kind of authentication their API will support and I did not found a good solution to override the code of the netatmo-dependency to continue working, this module contains an altered full-copy of the module. All credits for the original code go to the respective authors.
