If your device does not support this API level, this information is simply omitted. How do you know? Easiest way is to see if the data is reported. If your device does not support the background service, the application will clear this setting after you have enabled it. This tells you that you are unable to take advantage of the background reporting service for the functions below. ## Limits The values are merely samples of your device's current status. They are sent by a single background service at the repetition frequency you chose in the settings. The samples are sent at that one rate only, they _do not vary_ for example on in activity, on charge, time of day. You get one refresh interval and that is it. If you want to change the refresh interval, you change your settings. We do appreciate that may not be what you would ideally like to trigger actions on Home Assistant. Messing with the repeat interval of the background service requires more code, more settings and more complexity. That means older devices using widgets would have to be taken out of support to achieve it. **Please do not ask for these to be made 'events'.** Garmin's [Connect IQ background service](https://developer.garmin.com/connect-iq/api-docs/Toybox/System/ServiceDelegate.html) is limited in that while it does provide an `onActivityCompleted()` method, it does not provide an `onActivityStarted()` method, so you would not have the complete activity life cycle anyway. So we're keeping this implementation simple, you just get a sampling at one refresh rate. This probably limits you to updating a status on a Home Assistant Dashboard only. ## Battery Reporting From version 2.1 the application includes a background service to report the current device battery level and charging status back to Home Assistant. This is a feature that Garmin omitted to include with the Bluetooth connection. ## Location Reporting From version 2.6 the application includes reporting your location. The location data reported includes: - Location (latitude and longitude) - Location accuracy - Speed - Direction - Altitude You get whatever your device provides at the moment, i.e. at the accuracy the device currently provides. If your watch is not calibrated you get poor data. It might mean that you get more accurate location data when you are in a location tracking activity (i.e. not swimming pool lengths). The device [indicates an accuracy](https://developer.garmin.com/connect-iq/api-docs/Toybox/Position.html#Quality-module) in units of: - `Position.QUALITY_NOT_AVAILABLE` - No update provided - `Position.QUALITY_LAST_KNOWN` - No update provided - `Position.QUALITY_POOR` - We translate that to 500 m arbitrarily - `Position.QUALITY_USABLE` - We translate that to 100 m arbitrarily - `Position.QUALITY_GOOD` - We translate that to 10 m arbitrarily **You cannot rely on the radius of the circle of accuracy in any resulting maps as any meaningful indication of error.** ## Activity Reporting From version 2.6 the application includes reporting your activity. The activity data includes: - Activity - This is an integer as defined by [Toybox.Activity `SPORT`](https://developer.garmin.com/connect-iq/api-docs/Toybox/Activity.html#Sport-module) - Sub-activity - This is an integer as defined by [Toybox.Activity `SUB_SPORT`](https://developer.garmin.com/connect-iq/api-docs/Toybox/Activity.html#SubSport-module) The application only provides the integers without translation. When using the values in Home Assistant, you will need to provide you own mapping from the `Activity` enumerated type to the human readable text. As developers of the application we are pushing this translation to the server to keep the Garmin application code 'lean'. You will also need to add to both the list of activities (sports) and sub-activities (sub-sports) an interpretation of integer `-1` for no activity/sub-activity at present. ## Start Reporting The main drawback of this solution is that the Garmin application must be run once with the feature enabled in the settings before reporting will start. Reporting continues after you have exited the application. This is a limit we cannot code around. It should be as simple as starting the application (or widget). There should be a new device in the mobile app integration called `Garmin Watch` with the battery level and charging status. [![Open your Home Assistant instance and show an integration.](https://my.home-assistant.io/badges/integration.svg)](https://my.home-assistant.io/redirect/integration/?domain=mobile_app) If this is not the case, head over to the [troubleshooting page](Troubleshooting.md#watch-battery-level-reporting). ## Stop Reporting To stop the reporting, the option must be turned off in the settings and then the application run once. Running the application then removes the background service. Both the enable and repeat time settings can be changed whilst the application is running (i.e. live) and the background service will be amended. ## Renaming the device When the device is first created, it will be called `Garmin Watch`. This can be changed in the mobile app integration settings (button below). [![Open your Home Assistant instance and show an integration.](https://my.home-assistant.io/badges/integration.svg)](https://my.home-assistant.io/redirect/integration/?domain=mobile_app) Select the device called `Garmin Watch` and then click on the edit icon in the top right corner. You can then change the name of the device to whatever you like, then press `UPDATE` and then `RENAME`. ![Rename device](images/rename_device.png) ![Rename entity ids](images/rename_device_2.png) ## Fixing the icon In `configuration.yaml`: ```yaml template: - sensor: - name: " Battery Level" unique_id: "" device_class: "battery" unit_of_measurement: "%" state_class: "measurement" state: "{{ states('sensor._battery_level') }}" icon: "mdi:battery{% if is_state('binary_sensor._battery_is_charging', 'on') %}-charging{% endif %}{% if 0 < (states('sensor._battery_level') | float / 10 ) | round(0) * 10 < 100 %}-{{ (states('sensor._battery_level') | float / 10 ) | round(0) * 10 }}{% else %}{% if (states('sensor._battery_level') | float / 10 ) | round(0) * 10 == 0 %}-outline{% else %}{% if is_state('binary_sensor._battery_is_charging', 'on') %}-100{% endif %}{% endif %}{% endif %}" ``` ## Adding a sample Home Assistant UI widget A gauge for battery level with a charging icon making use of [mushroom cards](https://github.com/piitaya/lovelace-mushroom), [card_mod](https://github.com/thomasloven/lovelace-card-mod) and [stack-in-card](https://github.com/custom-cards/stack-in-card): In lovelace: ```yaml type: custom:stack-in-card direction: vertical cards: - type: custom:mushroom-chips-card card_mod: style: | ha-card { height: 0.25rem; } chips: - type: conditional conditions: - condition: state entity: binary_sensor._battery_is_charging state: "on" chip: type: entity icon_color: yellow entity: sensor._battery_level content_info: none use_entity_picture: false card_mod: style: | ha-card { border: none !important; } - type: conditional conditions: - condition: state entity: binary_sensor._battery_is_charging state: "off" chip: type: entity entity: sensor._battery_level content_info: none use_entity_picture: false card_mod: style: | ha-card { border: none !important; } - type: gauge entity: sensor._battery_level unit: "%" name: Watch needle: false severity: green: 50 yellow: 20 red: 0 card_mod: style: | ha-card { border: none !important; } ``` N.B. `sensor._battery_level` will likely need to be changed to `sensor._battery_level_2` if you have fixed the icon as above. ## Migrating You should remove your old template sensors before migrating to the new integration. You can do this by removing the `sensor._battery_level` and `binary_sensor._battery_is_charging` entities from `configuration.yaml` and then restarting Home Assistant or reloading the YAML. [Here is the old configuration method for reference.](https://github.com/house-of-abbey/GarminHomeAssistant/blob/b51e2aa2a4afbc58ad466f3b81667d1cd252d091/BatteryReporting.md) ## Deletion While all of the entries have the same name, you can identify which to delete by clicking through to its device which should have a changed name from when it was set up. ![Battery Device Deletion](images/Battery_Device_Deletion.png)
