I spent a long long time to get working communication between HA and /dev/ttyUSB0 device.
I want do a SIMPLE action : Send a command and receive a answer. Send a command isn’t a problem, but NOBODY was able help me how to receive a answer. It looks like that HA isn’t able receive a answer. If HA isn’t able do it, it’s scrap for nothing.
Is somebody has a working solution, please share. I have a HA sw running on the Odroid.
