Home Assistant Automations to control battery charging and DFS Saving Sessions

Battery Automations.txt

Note: I have a SolarEdge setup, so all the sensors are specific to that system.
The "Join Saving Session" automation was converted from bottlecapdave's blueprint.
For the event-logging code, see: https://gist.github.com/ChrisWarwick/52af80db86bb4e7527e376e383a3096a
