Posted December 23, 20222 yr Hi all, I had my Sunsynk 5kW firmware updated earlier today and have now noticed that I'm no longer receiving data into my Home Assistant via the RS485 connection. I've restarted HA and also done a complete power off. I've also tried changing the Baud rate in the Modbus setting in Node Red, my /dev/ttyUSB0 is still the same on my HA. All was working fine until the update was done, which included the inverter resetting itself... I'm just getting the following back in Node Red debug. "Modbus Failure On State sending Get More About It By Logging" old: M 3.1.6.2 / S -- / C E.4.1.9 new: M 3.3.8.2 / S -- / C E.4.2.6 I see the new MCU has "-0513" at the end Anyone seen this or got any ideas please? Apologies - I meant to start this topic in the Home Automation forum... recreating it there... Edited December 23, 20222 yr by RhysMcW probably incorrect forum...
December 23, 20222 yr Author I just tried moving the cable from the BMS485 port on the inverter to the RS485 port but no change...
