Had a further dig and found the below errors in /data/log/rgpio_driver/current

And having has a look at that line of code, I can see it makes a call which returns the following (when I added the DingTian IP address):

I am able to ping the DingTian:

So guessing this is an issue with the config in the DingTian?
Final update - the issue was that the DingTian TCP Server value was set to Modbus-TCP. When I changed it to Modbus-RTU over TCP everything worked :)
Hi,
I have been trying without success to get either of a pair of DingTian 4 relay units (one is RS485 + Ethernet while the other is CAN + Ethernet) to work over Ethernet (also tried the RS485 interface with no luck). Initially I found the old venus_rgpio and this did not work either (tried both RS485 with a non FT232R USB interface and then Ethernet).
Having reinstalled the 'small' Venus OS and your RemoteGPIO package and followed (I hope!) the instructions, I do see 4 extra relays in the GUI but the actual interfaces do not operate.
I had a look in the logs and foundthe lLatest message (numerous times) in /data/log/RemoteGPIO/current rgpio_driver: RemoteGPIO driver restart triggered by watchdog
My configuration is below.
Are there any other logs I should look in, and per the below information is my config correct?
Thank you.
