Hi,  
I was wondering if someone could help me add an LED on the dashboard that would blink when it receives any payload which is connected to a MQTT in node ?

Thanks In Advance  
Stuart

Something like this

```auto

Hi HotNipi,

Thanks I will give it a try, heres me thinking it would be a case of putting "If Payload" or something similar

cheers

Hi hotNipi,

Thanks for the solution it works great, I can also plug a stock LED node into the trigger but it doesn't look as good as yours with the shadow.

Cheers  
Stuart
