@bp2008 Sorry, you are correct. I didn't realize you had added MQTT capabilities months ago for switching cam/group view.@actran that is some good info about Music Player Daemon. If that works well on Android, it might be better than UI3 even if UI3 is always running, simply because it will never require user input after the page load to allow audio to play.
Basic remote controls via MQTT were added months ago. Not the ability to switch tabs though. I don't think that would actually offer any value. More valuable would be the ability to load a clip or a timeline position, but I have trouble thinking of how that would be useful to automate.
As you can see in screenshot below, I tried to switch from UI3 current "main2" group to "Doorbell" cam using MQTT Explorer but I don't see UI3 responding to that publish.
I can confirm that UI3 is connected to MQTT and when I manually switch groups from UI3, I can see that reflected in MQTT itself.
Any ideas where I am going wrong? Is my payload correct?
P.S. Side note, I do have BlueIris sending MQTT msgs to Home Assistant correctly, via Mosquito MQTT server installed on Home Assistant VirtualBox.
