Not sure on what exact settings you need for the Eastrom SDM630, but the baud rate seems a bit high, I suggest starting with 9600 and see what happens.

Also, I see port 26 and 23 used, did you set those values? I would expect to see 502 there.

These are my settings for a similar waveshare device connected to a Growatt inverter:

I connected both my Growatt 3000TL3-S inverters to the module and after some fiddling on the Inverters (Giving each a unique ID) and in the module’s settings I got it working! Here the settings that work for me: I made the following changes that differ with de module’s default settings: Network Settings Device Port, set it to 502 IP Mode, switched it …

(Suggestion: set the IP type to DHCP and add a reservation to your router if possible)
