sunlight-mqtt

Emit over MQTT when sunlight phases change (using SunCalc)

Breaking: v2.0 now emits true/false instead of {"value":true}/{"value":false} on night/dark events

Topics

Emits {prefix}/night and {prefix}/dark with data true/false where prefix is set in config.

Emits the current position of the sun every minute {prefix}/position with data {"azimuth": 0, "altitude": 0} where prefix is set in config. See suncalc for the values. You can also listen to {prefix}/azimuth and {prefix}/altitude for the individual values.

Beta: Emits {prefix}/phase with data "sunrise" "sunriseEnd" etc where prefix is set in config and values can be found on suncalc. The phase value emitted is the most recent phase entered.

Running

It is intended to be installed globally, ie npm i -g sunlight-mqtt

Create a YAML file somewhere. See config.example.yml

You can also use Consul for config. See mqtt-usvc for more details.
