Light from PRTG uses an unknown service

[sebgroves]

Getting the following error on the Home Assistant Setting page:

Light from PRTG uses an unknown service
The automation "Light from PRTG" (automation.light_from_prtg) has an action that calls an unknown service: script.unknown.

This error prevents the automation from running correctly. Maybe this service is no longer available, or perhaps a typo caused it.

To fix this error, [edit the automation] and remove the action that calls this service.

Do you have a sensor: sensor.prtg_script?

I removed everything and started again. the error has gone, but I am not getting and data pulled in and on the entities card I get the following error "Entity not available: sensor.prtgsensors". I have checked and I have no such sensor, just I can see it should be there from the prtg.yaml
Am I missing something obvious?

Do you have filled the secrets? And is the PRTG server available from HA?

What happens if you run this on HA:

t=$(cat secrets.yaml|grep prtg-api-token|awk '{print $2}');
u=$(cat secrets.yaml|grep prtg-url|awk '{print $2}');
curl  "$u?id=0&apitoken=$t"

that is quick and dirty a way to get the URL and token from the secrets file, and use it.

If it goes right, you will get a JSON back with some stats. That JSON is used in HA to get the counters.
