signalk-bang-displaydaynight

Auto adjust the display mode (night/day/backlight) based on different modes. Config can be created per network group.

The plugin supports currently 2 modes:

Mode

This mode subscribes to environment.mode and will switch between day and night. Backlight level for both can be set.

Sun

This mode subscribes to environment.sun and will switch between dawn, sunrise, day, sunset, dusk and night. Diplay mode and backlight level can be set for all.

Lux

This mode subscribes to a path providing the outside lux value and allows diplay mode and backlight level to be set for a lux range.

Commands are send out as N2K packets.

None / External

This mode doesn't do any automatic adjustment of the display mode or backlight, however you can use the PUT interface to manually change it with something like Node-RED. The path is: 'environment.displayMode.control'. The API expects a JSON object with 3 parameters:

• mode: day or night
• backlight: 1-10
• (optional) group: Default, or 1-6

Examples:

{"mode":"day", "backlight":"10"}
{"mode":"night", "backlight":5}
{"mode":"night", "backlight":1, "group": 1}

Here is an example flow for Node-RED:
