I followed the above steps and got to a point where the UI displays the camera stream and motionEye detects motion (pink squares, images are saved once motion is detected).
However, I’m running out of ideas to get the motion notification to work. I’m running motionEye as an addon to Home Assistant. I can’t get anything inside motionEye’s Run a command box to work. Are there any logs or loglevels that I could use? I reckon it has something todo with the containers but I’m not too familiar with containers.
I finally managed to get the webhooks runnings (verified on a shell command), i.e. the commands themselves. The last bit now is the trigger from motionEye to run a command.
