Hi, I may not have an immdeate solution but a very similar issue which I got solved. First: I do also run home-assistant in docker and recently upgraded to version 0.85.0 (kill me I am not sure of the previos version I believe something 0.7x…) before upgrade the shell command:
shell_command:
set_state_to_vent: '/usr/bin/phantomjs /config/vallox/click_vallox.js http://192.168.70.20 {{ states.input_number.state_vent.state | int }}'
worked flawlessly. Unfortunately phantomjs it seems was removed from the docker container. I had to install it manually and the manual version required an Env-var to be set to work.
for a
sensor:
- platform: command_line
name: Vallox Gesamt
command: "export QT_QPA_PLATFORM=offscreen; /usr/bin/phantomjs /config/vallox/read_vallox.js http://192.168.70.20"
this worked flawlessly, for:
shell_command:
set_state_to_vent: 'export QT_QPA_PLATFORM=offscreen; /usr/bin/phantomjs /config/vallox/click_vallox.js http://192.168.70.20 {{ states.input_number.state_vent.state | int }}'
it resulted in the same issue as above.
Finally I could resolve it for by putting the two commands into a script “click_sh”
shell_command:
set_state_to_vent: '/config/vallox/click_sh {{ states.input_number.state_vent.state | int }}'
Then I tried to get closer to the root-cause and confirgured a few “nonsense”-commands:
shell_command:
set_state_to_vent_1: '/bin/echo 1; /bin/echo 1; /bin/echo 1; /bin/echo {{ states.input_number.state_vent.state | int }}' # works
set_state_to_vent_2: '/bin/echo {{ states.input_number.state_vent.state | int }}' # works
set_state_to_vent_3: 'export QT_QPA_PLATFORM=offscreen; /bin/echo {{ states.input_number.state_vent.state | int }}' # fails
set_state_to_vent_4: 'export QT_QPA_PLATFORM=offscreen; /bin/echo 1' #works
set_state_to_vent_5: '/bin/echo 1' # works
set_state_to_vent_6: '/bin/echo te_st; /bin/echo {{ states.input_number.state_vent.state | int }}' # works
set_state_to_vent_7: 'export TEST=1; /bin/echo {{ states.input_number.state_vent.state | int }}' # fails
set_state_to_vent_8: 'export TEST_T=1; /bin/echo {{ states.input_number.state_vent.state | int }}' # fails
set_state_to_vent_9: '/bin/echo "_"; /bin/echo {{ states.input_number.state_vent.state | int }}' # works
set_state_to_vent_10: '/bin/echo "="; /bin/echo {{ states.input_number.state_vent.state | int }}' # works
I have the feeling for me the the error is reproducible if I use the export built in command plus a variable in the command but I am not 100% sure. Here the error for “set_state_to_vent_7”:
