HomeAssistant, modbus & E3DC Inverters

[creis (Christian)]

Hey folks,

anyone here got Homeassistant to work with E3DC & ModBus TCP working?
I have been searching the net and trying stuff for ages. I really would love to get this working by TCP polling. I have seen a howto that describes using rscp…

There are enough howtos for homematic, iobroker and the likes. But none for HA? Seems odd.
Or its too trivial and I am going this the wrong way.

You guys have any advice?

I think that’s all you need:

Read bitmask value of register in Modbus sensor

Hi. I’m working on the integration of my PV system into HA. My PV battery unit has a modbus interface to read the values from. I managed to get most of the desired values displayed in HA except for one particular register. The register is holding a bitmask UINT16 value and each of the bits (0-6) represent a boolean state of a sensor (on/off). Any idea how I can tell HA to use a specific bit for a sensor entity?

Huh.

That easy. Works like a charm. Thanks!
