Hi
as there's people here playing as well with domotic system I wanted to share my progress regarding the subject.
I've added recently a Victron GX Tank to my install and now able to integrate SuperSense with Victron. As a results through the Victron modbus interface I'm now able to see my tank levels in Home Assistant:
My UI at the moment has:
- a Telsa style power reporting, showing Grid/Generator consumption, PV production, Battery charge and discharge, AC/DC loads, Quality of the Grid line and Volts of my battery
- The tank levels, including the LPG
- Starter Battery of the Iveco daily status (volts + charging current)
- Generator Applet to start the generator remotely, current run runtime and reasons for the start (automatic based on conditions or manual)
- Input current limiter
the next things I want to add are:
- Display the battery autonomy I'll have for the next hours (based on current consumption)
- Display the tanks autonomy I'll have for the next days (based on the current day consumption)
- Reminder of when the tanks have been filled / emptied the last time (day)
- Button to start the generator manually for 1 hours (so that I press a button and won't need to manually stop it after 1 hour)
- A condition that it I start the generator remotely but AC is not detected after 2 mins it will restart the generator 2-3 times. Sometime the generator won't start immediately at the first try 
- Integration with my Alarm system (both to arm/disarm - but also to report if one the flap or door/windows have been left open)
Hope you like it
