A small tip, look at the following wiki page: https://www.domoticz.com/wiki/PersistentUSBDevicesrenerene wrote:I have managed to solve the permisseon denied issue on ttyAMA0 with help from this post
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?
Use the lsusb command to see all the devices connected on your Raspberry Pi.
