I created a Homebridge Plugin so you didn't have too

I noticed the lack of HomeKit support and was surprised to see no one had put together a Homebridge plugin yet. I took the liberty and put one together for everyone to use. Now you can make Apple Home automations based on some of your Tempest sensor readings.

It’s currently limited to a Temperature Sensor, Light Sensor and Fan (used to mock wind speed). It allows for flexibly for what temperature and wind speed readings you’d like to target.



I updated it to also include a Humidity Sensor. homebridge-weatherflow-tempest - npm


Plugin is now officially Homebridge Verified. Enjoy!


Nicely done! We were just re-exploring creating a HomeBridge plug-in this week! (separate from our effort to build native HomeKit integration into the ProHub) Can’t wait to check yours out!

Thanks @dsj! Let me know if you or your team have any ideas or if any of your Engineers would like to collaborate? Thanks!

After updating to the latest version, I’m getting the following errors:

I have installed and reinstalled. Updated the settings. I’m not sure what I have done wrong.


I’m sorry to hear you are having an issue.

The new 3.0.0 release is not backwards compatible and in most cases will require you to delete all your accessories and restart OR directly edit the Homebridge configuration JSON file.

Please share your configuration JSON file for the Weatherflow Platform and please redact any sensitive information.

Additionally you can report the issue and your config here: Issues · chasenicholl/homebridge-weatherflow-tempest · GitHub

Thank you!

I deleted the weather flow plugin and reinstalled because of it not being backwards compatible, but it didn’t seem to help.

Here is my configuration JSON file:
“name”: “WeatherFlow Tempest Platform”,
“token”: “hidden,
“station_id”: hidden,
“interval”: 10,
“units”: “Standard”,
“sensors”: [
“sensor_type”: “Temperature Sensor”,
“temperature_properties”: {
“value_key”: “air_temperature”
“sensor_type”: “Humidity Sensor”,
“humidity_properties”: {
“value_key”: “relative_humidity”
“platform”: “WeatherFlowTempest”

Hi @lauraf13 you are missing the “name” property. For your two Accessories you need to add a “name”: “” above each Sensor Type.

For example.

    "name": "WeatherFlow Tempest Platform",
    "token": "hidden",
    "station_id": hidden,   
    "interval": 10,
    "units": "Standard",
    "sensors": [
            "name": "Outside Temperature",
            "sensor_type": "Temperature Sensor",
            "temperature_properties": {
                "value_key": "air_temperature"
            "name": "Outside Humidity",
            "sensor_type": "Humidity Sensor",
            "humidity_properties": {
                "value_key": "relative_humidity"
    "platform": "WeatherFlowTempest"

Please let me know if that resolves your issue? Thank you.

Yes, that fixed my issue. Thanks for your help.

Additionally for anyone else who runs into this. We just released a 3.0.1 patch that should prevent this happening to others. Thanks for the feedback!
