Hi - I fixed my issue with node-red and now the Envi-Cost interface works perfectly.
The issue is because HASS OS runs Docker in supervisor mode, it does not have the necessary privs to use the Serial Port.
I connected to the console via directly connecting a monitor/keyboard to the RPi, rebooted.
Changed to the full root user via. ha > login
Added the world/others to the privs via # chmod 666 /dev/ttyUSB0
From there it connected no problems, even after a reboot.
I hope this helps - very frustrating this sort of thing!
It turns out hat the problem was caused by a bug in the serial driver in node-red. This has now been fixed in an update. Many thanks to the “fixers”.
