Screencast somehow collides with Remote Control API and the Integration to Home Assistant

Open fribse opened this issue 3 years ago • 7 comments

Yeah, I know this is fluffy. There is an integration into Home Assistant that uses the Remote Control API. If I activate the ScreenCast module, the integration doesn't work. I'm posting it here, but I will of course also post it in the Home Assistant Integration. Maybe you can explain me how this might happen, so I can explain it to the developer of the integration?

@fribse Hmm my intial guess would be a port collision or something similar. Do you have any logs of this? and what exactly are you using for Home Assistant and Remote Control? I might have some time to dig into this.

Odd, Remote control uses port 8080, where can I find some extra log files?

I just tested some more together with the @sindrebroch that does the Home Assistant Integration. Weird results.

Without ScreenCast billede I then send requests to RemoteControl API: /api/test: {"success":true} /api/mmUpdateAvailable {"success":true,"query":{"data":"mmUpdateAvailable"},"result":false} /api/monitor/status {"success":true,"monitor":"off"} /api/brightness {"success":true,"query":{"data":"brightness"},"result":100}

With ScreenCast billede RemoteControl API: /api/test: "success":false,"status":"error","reason":"unknown","info":"Not initialized, have you opened or refreshed your browser since the last time you started MagicMirror?"} /api/mmUpdateAvailable {"success":true,"query":{"data":"mmUpdateAvailable"},"result":false} /api/monitor/status {"success":true,"monitor":"on"} /api/brightness {"success":false,"status":"error","reason":"unknown","info":"Not initialized, have you opened or refreshed your browser since the last time you started MagicMirror?"}

Hmmm? So both the module scheduler and the remote-control is somehow affected. I've done a reinstall of MagicMirror, so the only thing left is the Raspberry OS I guess.

I just did a complete reinstall on a new SD card. Raspbian Buster, monitor in portrait mode (display_rotate=1). I've tried to install MagicMirror with both sdetwell's script, and manually, the same thing happens. I did a basic MagicMirror install, added the RemoteControl module with API key. As soon as I added ScreenCast it lost the ability to do proper API commands. I tried adding a specific port statement as well to the ScreenCast, just to make sure nothing was coliding, still no joy.
