Merge into ESPHome Core?

[BradleyFord]

Would it be possible to have this added directly into ESPHome?

Also it is really great that this in ESPHome, it is now super easy to setup and get running.

I guess it needs some more work on the modbus stuff. Needs to use the modbus component from esphome. Currently it uses the modbus code from the hcpbridge.

I definitely have this on the list, but currently I am a little time constraint. Since it is working fine at the moment, this is not my highest priority project ;)

Now that esphome/esphome#4874 (comment) is merged this should possibly be easier?

I had a look on the esphome modbus component. but I think at the moment not all needed functionality are present there.
In the source code there is mentioned that the needed modbus fuction Read write multiple register is not implemented.
This implementation is definitively above my capability.
READ_WRITE_MULTIPLE_REGISTERS = 0x17, // not implemented
