Assign Battery backed button to Bulb

Got it working!..didnt use anything in HA as such but used the bindings within Zigbee2MQTT - this works but maybe i need to tidy it up ?

What are those “source and destination” endpoint numbers…i just left those as 1…but goes to 247?
Ive got no dimming either but im happy for the moment as it goes on and off!!

I never really worked out how binding works
Try enabling LevelCtrl on all of them

Cheers - ill have a play when i get home from work…just to say that the reaction time between pressing the button and the light coming on is instantaneous…fastest reaction time to anything ive used yet on my network…am i right in saying the above “binding” is directly linking the button to the bulb…cutting out the home assistant server?

From what I’ve read, binding supposed to work even when z2m is offline?
You could try it out

Yeah - the way i see it yes…ive got some memory turning up for the VM box so ill try then…
