Name: L308 Auto
Author: mchardysam

A Garmin data field that changes a Magene L308 taillight's pattern automatically while you ride, to match how you're riding and to help the light's battery last.

You pick a pattern for each situation in the settings, and the field switches the light as things change during the ride. Each rule is optional, turn on the ones you want:

- Group mode: a steady, calmer pattern so you're not flashing the rider on your wheel
- Speed over a threshold you set
- Power over a threshold you set
- Cadence over a threshold you set
- The light's battery running low, drops to a lighter pattern to make it last
- Otherwise it holds your default pattern

It works with the patterns already stored on your light (put them there with the OnelapFit app), connects once when the ride starts, and only writes to the light when the pattern needs to change. There is also a manual mode that leaves the light alone.

Add it to a data screen on one of your ride profiles. Requires a Magene L308 taillight. Unofficial, not affiliated with or endorsed by Magene. For use with hardware you own.

Optional: you can also draw your own patterns for the light in a free browser editor (also unofficial): https://mchardysam.github.io/magene-l308-taillight/
