Hue Dimmer Switch no longer working via Hue integration

Hey all,

I’ve been using a Hue 4 button dimmer switch for ages to execute an automation when I long press it.

Has anything changed in how Hue integrates with HA? It was very useful to have this up and running.
Appreciate any tips to get this working again.

Here’s my automation:
