tl;dr
usb_pathis ignored in config for HA > 0.81
I’m in the process of migrating from a Raspberry Pi based HA setup which used a ZWave.Me controller, on port /dev/ttyAMA0 to a NUC and a ZWave USB stick on port /dev/ttyAMC0.
I started HA several times before I got as far as plugging in the zwave stick and it seems to have cached the original value I had in config from the Pi.
The odd thing is, even when I destroy the container & bring it back up, it still keeps the old config in place, even though the config in HA is now correct.
zwave:
usb_path: /dev/ttyACM0
debug: true
I’ve grep’d the HA config folder for the old port, but nothing comes up, could it be encoded in a file somewhere?
Here’s the error from the HA logs:
