Hi,
I had the problem that sometimes my Homey would lose the MQTT connection, which is why the dashboard would stop working. This would not be immediately visible, so I created a status indicator.
Just sharing the example here:
The signal symbol is orange if all is OK, it blinks orange/grey if no mqtt message was received in the past 30 seconds or longer, and turn red if no message was received for more than 2 minutes.
Here’s the flow:
Have fun with the code:

Are there things that changed the interaction with Node-red?
thanks for your feedback!
