@dougl I connected PPG to my 18kPV inverter and started reading the data (in ugly format) on Home Assistant. (I'll work on that later.) However, I also have a GridBoss on my system and when I started polling with the Python Protocol Gateway I had a Para Sync Loss event. Do you have any paralleled devices (Inverter or GridBOSS) and have you had this event occur? I shut down polling and disconnected and reconnected one of my parallel cables and the system resynced. I have not tried to reconnect since then. Looking for guidance.

@EG4 Eric Please review my comment to Doug and let me know if you have any insight.

@weertske I do not have any parallel devices, just the 18KPV so maybe EG4 is using that rs485 port for parallel comms and there's too much traffic on the bus.

I've left the default refresh rate for PPG which is far faster than the 3 minute update rate of the WiFi dongle. Speaking of such, that might be an option, ie remove the WiFi dongle and use that RS485 port.  If you need remote control then you could swap the WiFi dongle back in momentarily. Or you can try slowing down the refresh rate of PPG.

@dougl I had the dongle off when this occurred. I'll try changing my read rate from 10 seconds to 60 seconds. Thanks.

@weertske if you are using the RS485 port with the RJ45 connector(eithernet) then that shares with the WiFi dongle IIRC.

I'm using the 2nd RS485 port which is located in the green screw terminal block in the bottom right of the communications board and below all the RJ45 ports.

@dougl I am using the green terminal also but I disconnected the wifi just to remove variables.

@weertske then if you are willing to go without the WiFi dongle, I would go back to that and use the RS485 which is shared with the WiFi instead of the B channel RS485 which appears to be used with parallel systems. It makes sense for EG4/LuxPower to us that secondary RS485 for parallel comms because they'd want to keep the remote control capability(WiFi) operational.

@dougl I can confirm that switching back to the A channel which shares the WiFi dongle works fine. I also slowed down my data polling to 60 seconds and both WiFI and data collection work.
