Garmin Vivoactive 4 with Home Assistant
This morning I saw a Reddit post where someone connected their flipper zero to a Fossil HR through Gadgetbridge. I immediately started ducking, trying to find out if I could do the same with my Garmin Vivoactive 4 but ended up realizing that there was no apparent way to connect the two. I did however find a widget compatible with my watch named APICall on the Connect IQ store.
This widget interested me because it allowed me to call any webhook I wanted utilizing the onboard Wi-Fi as well as through the Connect IQ app. This was a very important feature for me because I canβt get the app to run on LineageOS as it keeps asking for the location permission even though it was already granted.
My first idea was to try to broadcast a message to the Google home using ismarslomic/google-assistant-broadcast, but it ended up being broken. I decided, therefore, that since the project was unmaintained to try Home Assistant with the Google Assistant SDK.
The setup was amazingly quick, using the linuxserver/docker-homeassistant image and their sample compose file, I was able to get it fully running in under 10 minutes.
Now for the Google Assistant SDK / APICall / Home Assistant tutorial. The first thing you want to do is follow this guide, Google Assistant SDK - Home Assistant, to install the Assistant SDK. Once you have completed that, go to Settings / Automations & Services.
This is where you can create the action that you want to trigger with your smartwatch. The first thing you need to do is to create a new automation. Save and name the automation you just created. Now add a trigger, scroll to the bottom of the list and select webhook. If done successfully, it will look like the image below.
Now add an action. I decided to use the media player to play a song on Spotify. Also go back to the webhook section and click the settings icon next to the webhook ID. Change the settings to reflect below screenshot.
Now for the fun part. Download APICall onto your Garmin smartwatch and go to the configuration section for the app.
Note: Iβll be using Garmin Express on my MacBook, but you can also use the Garmin Connect app on a phone.
If you are using Garmin Express, then you can access the app settings by selecting the 3 dots next to the app. You will have 36 possible API calls that you can enter.

These are the actions that I configured for my watch so far. To customize for your API calls you need to change the deviceName
, actionName
, and url
fields. The method
and headers
need to stay the same across all actions. If you want to add an icon to that action, then you can configure that with the actionIcon
field. A table with the possible icons is included below, sourced from APICallβs documentation.
In conclusion, you can use APICall to trigger actions in home assistant from your Garmin smartwatch. I hope this tutorial proved to be useful, and have a great rest of your day (or night).
