@Lewis-S, what if you run that from a bash prompt while you're ssh'ed into the Pi?
This is what I get:
pi@pi:~ $ ./test.sh
Fri 3 Apr 19:31:08 UTC 2020
./test.sh: line 2: pihole: command not found
{"errors":[{"message":"You sent an invalid key."}]}./test.sh: line 8: pihole: command not found
{"errors":[{"message":"You sent an invalid key."}]}
To confirm whether it's running the commands after the sleep, can you add a line like this to see if it creates the log file?
echo Testing after the sleep > /tmp/log.log
I did that and I get the log file, including if I run it via TRIGGERcmd:
pi@garagepi:~ $ cat /tmp/log.log
Testing after the sleep
My commands.json entry looks like this:
{"trigger":"testsh","command":"\/home\/pi\/test.sh","ground":"background","voice":"test"},
