Describe the problem

Hey guys,

I have a clean install of homebridge and this wonderful plugin. Unfortunately, I get the following errors (couldn't find anything related on google or github):

[1/24/2024, 10:21:41 AM] [UniFi Protect] Dream Machine Pro [XXX] Front Door [G4 Doorbell]: Unable to process MQTT message: "". Error: Unexpected end of JSON input. [1/24/2024, 10:21:41 AM] [UniFi Protect] Dream Machine Pro [XXX]: Unable to process MQTT liveview setting: "". Error: Unexpected end of JSON **input.

Anyways, [homebridge-unifi-protect] is working for quite some time but without any notice it stops doing anything and not recognizing any more motion or ring events.

Any advice?

Thanks! Markus

Thanks for the report - the error is because something is trying to speak to HBUP via MQTT and trigger an event and is doing so incorrectly or in an unsupported way. What’re you doing with MQTT?

[marrrkus]

Sorry, I was on a business trip.

I am pushing ring and motion events to ioBroker. There should not be any request coming from ioBroker.

I would take a closer look at what’s coming across MQTT. This message is because someone is publishing a message to unifi/protect/XYZ/liveviews/set - I’m afraid there’s not much more I can do here. Look at the MQTT documentation for more detail on what HBUP expects (in this case a JSON) when using that message.

Best of luck!
