Is there any way to get the return code from the shell_command
, so that I can send a notification if it failed?
I don’t think you can get the return code, but an exception should be logged if anything goes wrong: source code.
I guess you could use that as a trigger for your automation: System Log – Conditional Messages.
You could use a command_line
binary sensor, like (from the doc):
binary_sensor:
- platform: command_line
name: Printer
command: 'ping -W 1 -c 1 192.168.1.10 > /dev/null 2>&1 && echo success || echo fail'
device_class: connectivity
payload_on: "success"
payload_off: "fail"
Thanks a lot! For this use case I’ll use the solution @ondras12345 suggested, but the binary_sensor
solution might be useful some other time as well.
