I have been trying to get modbus working on HA 2024.3.3 but it doesn’t seem to do anything except giving an error:
Logger: pymodbus.logging
Source: components/modbus/modbus.py:448
First occurred: 8:39:11 PM (47 occurrences)
Last logged: 8:50:38 PM
Connection to (010.010.010.014, 502) failed: timed out
It’s not even trying to make a connection when I monitor the connection from a monitor port with Wireshark. What I at least expect to see is some traffic to the modbus slave device from the TCP handshake.
I tried several configurations, but nothing works really, not even when I simulate a modbus client from a modbus slave.
It appears to me your problem may lie with the connection?
Have you tried using: 10.10.10.14 for the IP instead of 010.010.010.014? That failed to connect “First occurred: 8:39:11 PM (47 occurrences)” so that seems to be your problem to me atm?
Worth checking/eliminating in any case don’t you think?
Your config looks fine to me otherwise.
PS: Did this just stop working with HA 2024.3.3? Or are just setting it up under HA 2024.3.3?
