Hi,
I installed a new energy meter in my house, this little one has Modbus.
Now I never worked with modbus before, and i really want to integrate this into my Pimatic.
I have a rs485 shield and i have a usb to rs485 converter.
If possible i want to use the shield on the raspberry.
The shield is connected now, but now i get stuck…
How to test connection?
etc…
Please help
thanx
