Since the last update of Home Assistant phase values are no longer available through modbus/TCP.
I get this error:
ERROR “Error processing function code 3, unit id 247, start address 865, quantity 2, src … : Error finding service with device type system at device instance 256”
Where should I start debugging?
That does sound like a question better asked on an HA forum.
If nothing changed on the GX side, then it is an HA implementation issue.
I wonder why Home Assistant is looking for unit id 247. It’s not listed under the available services on my Multiplus.
I am not that familiar with modbus.
unit ID 247 seems to be instance number 256 or vedirect port 1 on a CCGX, according to the docs.
