3 months ago I think the issue is linked to a connect optimization that keep the last connection, but it can't work if you have several inverters
My change was to keep the last serial used. If it's the same, so ok use the current connection. Else it's probably necessary to close the current connection before opening a new one, not sure about that
def connect_to_server(self):
if self._modbus and self.last_serial == self._serial:
return self._modbus
log.info(f"Connecting to solarman data logger {self._host}:{self._port} (serial: {self._serial}, modbus: {self._mb_slaveid})")
self._modbus = PySolarmanV5(self._host, self._serial, port=self._port, mb_slave_id=self._mb_slaveid, logger=log, auto_reconnect=True, socket_timeout=15)
self.last_serial = self._serialNow it works :-)

Hi Stephan,
I add in ha my first inverter and it works well :-) Then a couple of days after I configure another inverter as a slave (with parallel option) and add it too to ha. Configuration seems ok in the plugin, but no info are reported on this second device.
So the log show some interesting errors. Most interesting log is " failed with exception [V5FrameError: V5 frame contains incorrect data logger serial number" But I'm sure that my logger SN (not inverter SN) is correct since with another tool I grab data ('192.168.2.142', 8899) => this is the IP of the second inverter 2907701578 is the correct SN of the second inverter.
Notes:
in this log, we can see the config of the 2nd device:
2024-03-19 16:42:53.205 DEBUG (MainThread) [custom_components.solarman.config_flow] config_flow.py:step_user_data_schema: {'name': 'deye2', 'inverter_host': '192.168.2.142', 'inverter_serial': 2907701578, 'inverter_port': 8899, 'inverter_mb_slaveid': 1, 'lookup_file': 'deye_hybrid.yaml'}

Laurent
