This is a weather plugin for homebridge that features current observations, daily forecasts and history graphs for multiple locations and services. You can download it via npm.

Screenshots Screenshots 2 and 3 are taken from the Elgato Eve app.

If you like this plugin and find it useful, I would be forever grateful for your support:

Buy Me A Coffee

Feel free to leave any feedback here.


  • Get 27 observation and forecast values for up to 7 days
  • Choose from 3 different weather services
  • Add multiple locations/services
  • See the weather history in the Eve App
  • See all values, translations and icons in the Eve App
  • See all values in the Home app with compatibility mode "Home"
  • Use all values in HomeKit rules with the Eve App
  • Configure everything easily with the homebridge config-ui-x

Choose your Weather Service

This plugin supports multiple weather services. Each has its own advantages. The following table shows a comparison to help you to choose one.

OpenWeatherMap (recommended) Weather Underground 2 Tempest weather station 7
Current observation values 15 12 20
Forecast values 186 0 0
Forecast days today + 76 0 08
Location city name, geo-coordinates station id local
Personal weather stations ✔️ ✔️ ✔️
Free ✔️ ✔️ (only if you own a station) ✔️ (you need the station)
Register here here -

You can add more services easily by forking the project and submitting a pull request for a new api file.

2 You can use the weather underground service only if you can provide weather data from your own station in exchange.
6 uv-index, dew point, sunrise, sunset are only available after registering for the new OpenWeatherMap One Call API 3.0, which is free as well. The old API also has 4 instead of 7 forecast days.
7 Weatherflow's Tempest is a physical weather station that can be installed in your home. Current weather conditions are published on home network.
8 Weatherflow does provide an API to retrieve forecast. That capability has not been added to this plugin.


  1. Install homebridge using: npm install -g homebridge
  2. Install this plugin using: npm install -g homebridge-weather-plus Note: The installation might take 5 minutes.
  3. Gather an API key for a weather service from the register link in the table above
  4. Configure via the plugin homebridge-config-ui-x or update your configuration file manually. See the explanations and samples below.

Observations and Forecasts

The following observation and forecast values can be displayed and used in HomeKit rules, though not all weather sources provide all values below.
I recommend using the Eve app to see all the values. However, if you don't want to use a 3rd party app, use the compatibility mode home for displaying most values in the Apple home app.

4 Detailed: clear (0), few clouds (1), broken clouds (2), overcast (3), fog (4), drizzle (5), rain (6), hail (7), snow (8), severe weather (9)


Below are example configurations for all weather apis.


The API key that you get by registering for the OpenWeather service API 3.0.

  • The service requires a payment method despite being free for 1000 calls per day. The plugin should not exceed this limit in the default interval configuration, but I cannot guarantee that!
  • To be on the safe side you can limit your api key to 1000 calls on the OpenWeather website under "Billing plans".
  • It can take up to 30 minutes until a newly generated ApiKey is accepted.

City name and optional country code, can be found here.

List with the latitude and longitude for your location (don't forget the square brackets). You can get your coordinates: here.

5 You need only one of these location options.

"platforms": [
		"platform": "WeatherPlus",
		"service": "openweathermap",
		"key": "YOUR_API_KEY",
		"locationCity": "Berlin, DE",
		"locationGeo": [52.5200066, 13.404954]

Weather Underground

Since March 2019 you need to register your own weather station with Weather Underground to get weather data in exchange. After you registered your weather device (here), you can use the API.

The API key that you get by registering for the Weather Underground service.

Your personal StationID.

"platforms": [
        "platform": "WeatherPlus",
        "service": "weatherunderground",
        "key": "YOUR_API_KEY",
        "stationId": "YOUR_STATION_ID"


WeeWX is an open source software for your weather station monitoring that can be found (here), to utilize this plugin you need to have the following extension that create a JSON input that can be found here. Once that is installed a JSON response needs to be created using the following template that creates a JSON file on your server which can be created by adding a new file called YOUR_FILE_NAME_HERE.json.tmpl and adding it to the skin.conf file.

Weewx doesnt use a key but uses the key as the location for your JSON file. Just place the URL in the key and the app will use that to pull the json location.

Used to indicate Weewx version. The homekit plugin requires an location field that is used to run. It technically can be any text you want but I just have added the Current Weewx versin..

"platforms": [
        "platform": "WeatherPlus",
        "service": "weatherunderground",
        "key": "http://weewx.lan/homekit.json",
        "locationCity": "V.4.3.1"

Tempest Weatherflow

The Tempest Weatherflow is a local weather reporting device that publishes the current weather on the local network via UDP packets. Data is broadcast once per minute, so the Interval setting is ignored. The physical station can only provide the current weather. Future forecasts are available with this weather source, though has not been implemented yet. This uses data published on your local network for the current weather, and therefore runs fine without an internet connection.

        "platform": "WeatherPlus",
        "service": "tempest"

Advanced Configuration

Below are explanations for a lot of advanced parameters to adjust the plugin to your needs. All parameters are optional.

Compatibility for the Apple Home app, the Eve app or both. This is required due to limitations in the Apple Home app recognized weather conditions. The default is "eve".
"eve" (recommended) Use this for the Eve app or another 3rd party HomeKit App. All conditions will be displayed. The Apple Home app will show only temperature and humidity.
"eve2" Same as above but the values for temperature, humidity and pressure will be grouped into a single row. The Apple Home app will show nothing.
"home" Use this if you don't want to install a 3rd party HomeKit App but want to see as many values as possible in the Apple Home app6. 3rd party apps will show some useless sensors that are required for Home app support.
"both" Combines eve and home. You will need to hide some useless sensors in the Eve app that are required for Home app support. But after that you will get a solution that looks nice in the Home app and in 3rd party apps at the same time.

6 The following values will be represented as occupancy sensors that trigger on specific limits: CloudCover > 20%, UVIndex > 2, WindSpeed > 4 m/s, Rain, Snow

Detail level of the condition category. Not available for WeatherUnderground. Default is "simple".
"simple" 4 different categories
"detailed" 10 different categories

extraHumidity (compatibility "eve" or "both")
Separate humidity from the weather accessory to an own accessory if set to true. Default is false.

List of forecast days with 0 for today, 1 for tomorrow, 2 for in 2 days etc. Default are none []. Maximum depends on the chosen weather service.

List of observation and forecast values that should not be displayed. Possible options are ["AirPressure", "CloudCover", "Condition", "ConditionCategory", "DewPoint", "ForecastDay", "Humidity", "ObservationStation", "ObservationTime", "Ozone", "Rain1h", "RainBool", "RainChance", "RainDay", "SnowBool", "SolarRadiation", "TemperatureMin", "UVIndex", "Visibility", "WindDirection", "WindSpeed", "WindSpeedMax"]. Don't forget the square brackets.

Update interval in minutes. The default is 4 minutes because the rate for free API keys is limited.

Translation for the current day. The default is en.

Name for the current condition accessory. The default is "Now". You could set this to your city name or weather service type.

Name for the forecast accessories. Adds a prefix to the forecast days. You could set this to your city name or weather service type as well.

now Option to hide the Now accessory if you only need forecasts. Default is true which shows the Now accessory. Set to false to hide it.

Conversions used for reporting values. The default is "metric". The options are:
"si" or "metric"
"sitorr" to report air pressure in mmhg
"us" or "imperial"
"ca" to report wind speeds in km/h "uk" to report visibility in miles and wind speeds in miles/h

thresholdAirPressure (compatibility "home" or "both")
At what threshold should the air pressure sensor trigger? Provide a number without unit. The range depends on your unit setting (sitorr -> mmhg, otherwise -> hPa).

thresholdCloudCover (compatibility "home" or "both")
At what threshold should the cloud cover sensor trigger? Provide a number between 0 (clear) and 100 (overcast).

thresholdUvIndex (compatibility "home" or "both")
At what threshold should the UV-Index sensor trigger? Provide a number >= 0. See https://en.wikipedia.org/wiki/Ultraviolet_index

thresholdWindSpeed (compatibility "home" or "both")
At what threshold should the wind speed sensor trigger? Provide a number without unit. The range depends on your unit setting (si/metric/sitorr -> m/s, ca -> km/h, uk/us/imperial -> miles/h).

Customization of the history storage system. By default, the history is persisted on the filesystem. You can set your own option using this parameter. In order to change the location of the persisted file or to use GoogleDrive. Do not modify the parameter for the fakegato internal timer.

Multiple Stations Configuration

You can set up multiple stations for different locations and weather services by putting your configuration in a stations array. The following parameters are global and must be placed outside of the array: platform, interval, units.

Each stations must have a unique displayName. If you don't set one, the plugin will take care of that.


"platforms": [
        "platform": "WeatherPlus",
        "interval": 5,
        "units": "si",
        "stations": [
                "displayName": "Berlin",
                "displayNameForecast": "Berlin forefacst",
                "service": "openweathermap",
                "key": "YOUR_API_KEY",
                "forecast": [0,1,2,3,4,5,6],
                "locationGeo": [52.5200066,13.404954]
                "displayName": "Los Angeles",
                "displayNameForecast": "Los Angeles forecast",
                "service": "openweathermap",
                "key": "YOUR_API_KEY",
                "forecast": [1],
                "locationGeo": [34.0536909,-118.2427666]

Example Use Cases

  • Switch on a blue light in the morning when the chance for rain is above 20% today (or white when the forecast condition is snow / yellow when it's sunny).
  • Start your automatic garden irrigation in the evening, depending on the amount of rain today and the forecast for tomorrow.

Hint: To trigger rules based on time and weather condition you will need a plugin like homebridge-delay-switch. Create a dummy switch that resets after some seconds. Set this switch to on with a timed rule. Then create a condition rule that triggers when the switch goes on depending on weather conditions of your choice.
