Solar - Solis Inverter real time Dashboard

Solis inverter / Pylontech battery arduino integration for remote panel etc without a dependency on third party cloud services. The inverter and batteries expose RS485 integration potential.

Arduino seems lighter/simpler for, effectively an HTML data and Webserver front end on the inverter.

Current state:

Shelly control integration to enhance SOLIC functionality - turn on when batteries are full and solar in production. + POC off the shelf device control accessing the JSON/HTTP arduino interface.
Self contained/zero install dashboard served from the Arduino at path solis.local
Arduino web server & internal cross client cache
Inverter integration working with Modbus/RS485 connection.
Basic HTML/JS Dashboard consumer showing real time/~2 second updates.
Todays total kWh added.
mDNS hostname to IP lookup
Basic wifi reconnection on loss logic
Integration with browser animation callbacks to reduce load for background windows

Known issues:

mDNS seems to lockup sometimes esp. moving between mesh wifi transmitters.

Intention:

Local physical, moving coil, meter readouts for inverter real time data display.
Potential to locally consuming any inverter parameter for logical control of other devices.
