Home-Assistant EPEver eBox-Wifi-01 using MODBUS over TCP

How to extract data from the EPEver TRACER-AN using the eBox-Wifi-01 with Home Assistant.

• Make sure you're able to connect your eBox-Wifi-01 to your WiFi network, so your Home Assistant can reach it!
• Follow my quick guide here: https://github.com/gabrielpc1190/eBox-Wifi-01-hacks
• Some of the registers that worked came from this PDF: http://www.solar-elektro.cz/data/dokumenty/1733_modbus_protocol.pdf
• More info on registers available: https://files.i4wifi.cz/inc/_doc/attach/StoItem/7068/MODBUS-Protocol-v25.pdf
