Smart Bike Lights (Data Field) / Bike Lights Control (Widget)

I've made two open source CIQ applications to control ANT+ lights:

- Smart Bike Lights (data field): https://apps.garmin.com/en-US/apps/0d9fd828-c932-4470-9c37-fd2828881888

Configurator: https://maca88.github.io/SmartBikeLights/

- Bike Lights Control (widget): https://apps.garmin.com/en-US/apps/fa3c2332-76e3-4ba1-8528-32a0fd617ab1

Configurator: https://maca88.github.io/BikeLightsControl/

Smart Bike Lights features:
- Automatic light control (Smart mode) based on the configured filters (sunset, sunlight, speed, ...)
- Manual light control (only for Edge devices with a touch screen or devices with CIQ 3.2 and more than 32KB memory)
- Records lights modes that are displayed in Garmin Connect

Bike Lights Control features:
- Manual light control (available to all devices)

Both applications can be installed on the same device, which can be useful for low end devices (e.g. Edge 520) where "Bike Lights Control" can be used to change light modes manually and "Smart Bike Lights" for automatic light control.

Currently registered ANT+ lights:
- Bontrager Ion Pro RT
- Bontrager Ion 200 RT
- Bontrager Flare RT
- Garmin Varia RTL500
- Garmin Varia RTL510
- Garmin Varia RTL515
- Garmin Varia HL500
- Garmin Varia UT800

in case your ANT+ light is not on the list you can help by doing the following:

1. Install Bike Lights Control
2. Pair your bike light with your Garmin device
3. Open the widget:
- Edge with a touch screen: post which numbers are displayed on the buttons and what mode each button represents when pressed
- Other devices: Select the "Light modes" menu and post which numbers are displayed in the menu and what mode each menu item represents when selected

Example for Bontrager Ion Pro RT:

1 -> High steady beam
2 -> Medium steady beam
5 -> Low steady beam
63 -> Day flash
62 -> Night flash

There are some features that could be possible to add in the future, but would require Garmin to add them to the CIQ api. In case you are interested in any of the below features, consider upvoting their feature request thread:

1. Control lights based on the ambient light sensor available on some devices:

Thanks a lot for creating the test version — I really appreciate it.

I tested it and overall it does work, but in some cases it behaves a bit inconsistently.
Here’s what I observed step by step:

Expected / correct behavior:

When I open the activity, the data field initializes and the light is off.
When I start the activity, the light switches to the configured mode (in my case in the evening: mode 1).
When I pause the activity, the light turns off.
When I resume the activity, the light switches back to mode 1.

So far, this works exactly as expected

Unexpected behavior:

If I manually change the mode using the widget (e.g. to mode 6):
- The light correctly switches to mode 6.
- The widget highlights 6 and switches to manual mode.
But if I then switch to “S” (Smart mode):
- Mode 1 gets highlighted in the UI,
- but the light itself does not change and keeps flashing in mode 6.
Now, if I pause the activity:
- The light turns off correctly.
When I resume the activity:
- Mode 1 is highlighted,
- but the light still continues flashing in mode 6.

Manual (“M”) mode also behaves oddly:

Switching to mode 6 works and highlights correctly.
After that, switching to any other mode does nothing — no mode change and no highlight change.

Let me know if you want me to test any specific scenario or build.

Got this working on my 1050 and RTC715:

###0,73535488::1:#4,4!CARON:1:7:2:0I[120]0!Brake:1:4:2:0A[-10!Night:1:6:2:0Es-1800,r1800!:1:0:0:0D=1##6,5:Varia 715:0:16777215:-1!2,:-1,Off:0!1,Solid:4!1,Peloton:5!1,Day Flash:7!1,Night Flash:6#0::#0:1#123!:123!#0#0#B4440##11#0#0
