thats if i change it to pymodbus

kellerza commented 2 years ago

Umodbus requires the port to start with serial:// so you end up with serial:///dev/ttyUSB0

McAllstar commented 2 years ago

thanks I realised it was an issue on my side with the configs

Hi

Hope you are well. Any idea why I could be getting this? I did a complete re-install of HA and only installed mosquito etc and then the Sunsynk addon and I get this below.

Thanks Brett

@.***

It seems as if it makes the connection but it’s unable to read. My cabling is correct, and I tried using umodbus with serial: ///dev/ttyUSB0 and also pymodbus /dev/ttyUSB0sr

The only other way to do this is to use mbusd as a tcp to rtu gateway then connect to tcp://ip:port

McAllstar commented 2 years ago
