Generator Manager

This auto starts the generator when it's below "auto-start-soc" until it's "stop-charge-soc". Also adjusts shore or generator limit on the multiplus based on the generator status.

Requirements:

• adjust config (see config.example.json)
• It can talk to LCI gateway on http://192.168.1.4:8080/rest/things/.
• You have a generator connected to your LCI system.
• You have a Victron MQTT endpoint with a multiplus

Dev notes:

Code is very messy right now. Needs a heavy rewrite/refactor- though it's one of those things that works even though it's messy.

LCI Gateway Exporter

Requires: LCI gateway available on http://192.168.1.4:8080/rest/things/.

Exports the current state of your connected devices. It is designed to be used with Prometheus to capture the state over time as metrics. And a tool like Grafana to visualize as charts, text, bars, etc.
