Hi,
Been running HA for a while on an RPi2, had a bit of a disaster last week and ended up replacing it with an RPi3. Fresh Raspbian install and clean HA install. Problem is that on the RPi2, the RFLink device showed up as /dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_556323138383518111F1-if00, and this goes into the rflink component config and it all worked lovely.
But on the RPi3, /dev/serial/ doesn’t even exist, so I don’t know what to put in the configuration file for the port.
The RFLink is seen by lsusb:
pi@homeassistant:/dev $ lsusb Bus 001 Device 004: ID 2341:0042 Arduino SA Mega 2560 R3 (CDC ACM)
If I look in dmesg, I can see the device is recognised:
[ 1.948695] usb 1-1.3: new full-speed USB device number 4 using dwc_otg [ 2.063796] usb 1-1.3: New USB device found, idVendor=2341, idProduct=0042 [ 2.066298] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=220 [ 2.071103] usb 1-1.3: Manufacturer: Arduino (www.arduino.cc) [ 2.073593] usb 1-1.3: SerialNumber: 556323138383518111F1
In raspi-config, the serial login shell is disabled, and the serial hardware is enabled.
I’ve got this in /boot/cmdline.txt
dwc_otg.lpm_enable=0 dtoverlay=pi3-disable-bt root=/dev/nfs nfsroot=10.10.1.8:/volume1/piboot/homeassistant-root rw ip=dhcp rootwait elevator=deadline
Same result if I remove the pi3-disable-bt overlay bit.
This is what I’ve got in /dev
