Hello,
I'm going to add my problem similar to this question.
I purchased xG18 and connected it to Neuron L203, in which I use node red. I have two xS11s besides the xG18 and I connected everything via /etc/evok.conf, so I can see all the extensions in the configuration panel.
However, I can relay outputs through Unipi Nodes (input,output) but I can't read temperatures from xG18 this way.
The thermometers are reported as UART 3 3.1-8, but cannot be read.
I have also tried a form such as UART 3 3 1 (As in the configuration panel), but also to no avail.
I also tried the MODBUS RTU node but there I reached an Error on the bus. "Error: data length error, expected 21 got 1"
Did you come to any solution like temperature read out?
Thank you and happy thinkering
