Hello, I just want to share how I hooked up a 1TE DIN Rail Energy Meter “WS100-1943” from “B+G E-Tech” to Home Assistant via ModBus RTU. Nothing special, works right away. Technical details including register list can be found here: https://stromzähler.eu/media/ee/97/41/1704818760/WS100-19xx_1123_DE.pdf
