The cable is succesfully tested, using my Windows10 laptop, after fidling with some settings (baudrate, stop bits, etc) in the terminal program.
However: still no smart meter devices show up in Domoticz after clicking 'enable hardware for 5 minutes'
Also, in putty i can not get correct screendumps.
- which port to choose? (ttyAMA0, ttyUSB0, ttyUSB1 or ttyACM0)
- what is the correct CU command line for a Kaifa MA105C?
A small tip, look at the following wiki page: https://www.domoticz.com/wiki/PersistentUSBDevices
Use the lsusb command to see all the devices connected on your Raspberry Pi.
