Alright, here is an update to this…
I created another sensor in my currently working non-hassio HA in docker and strangely I get that same result.
Here is the sensor code:
- platform: command_line
command: 'curl -k --silent "http://192.168.1.56:8006/cgi-bin/CGIProxy.fcgi?cmd=getDevState&usr=xxxx&pwd=yyyyy" '
name: "livingroom Camera Motion test"
And here is the resulting sensor which is in the same format as the one I thought was not working correctly:
I still don’t know why the returned value is different running the same command as a command_line sensor compared to running the exact same command in the console.
And the “grep” portion of the existing command_line sensor works with that command too.
here is that sensor that is working exactly as expected:
- platform: command_line
name: "Livingroom Camera Motion"
command: 'curl -k --silent "http://192.168.1.53:8003/cgi-bin/CGIProxy.fcgi?cmd=getDevState&usr=xxxx&pwd=yyyy" | grep -oP "(?<=motionDetectAlarm>).*?(?=</motionDetectAlarm>)"'
value_template: >-
{%- if value == "0" -%}
Disabled
{%- elif value == "1" -%}
None
{%- elif value == "2" -%}
Detected
{%- endif -%}
scan_interval: 3
#friendly_name: 'Livingroom'
So, now I’m guessing it really is the way I’m setting up the regex_findall_index filter in the template that is causing the problem.
Here is the new non-working sensor:
- platform: command_line
command: 'curl -k --silent "http://192.168.1.56:8006/cgi-bin/CGIProxy.fcgi?cmd=getDevState&usr=xxxx&pwd=yyyy" '
name: "livingroom Camera Motion test template"
value_template: >
{% set status = value | regex_findall_index('(.*)</motionDetectAlarm>') %}
{% if status == "0" %}
Disabled
{%- elif status == "1" -%}
None
{%- elif status == "2" -%}
Detected
{% else %}
Not Determined
{%- endif -%}
scan_interval: 3
and here is the error generated:

So i’ll tag @123 & @petro to see if they can shed some light on this confusion.
Please?
