I just installed a new ceiling light and it is very bright. The light themselves are not smart, but I have a smart dimmer switch. Is there a way for the light to always turn on at the same percentage (of dim-ness)?

I usually either turn them on with the wall switch (which keeps the last setting used) or through Siri. Obviously I could ask Siri to turn it on at a certain percentage, but since it is always the same, was wondering it I could set a percentage as a baseline whenever I turn the light on?

I already had an automation to turn another light when this light is switched on, so I made sort of a circular automation where when that second light is turned on, it dims the ceiling light to 65%. It works, but it’s not super elegant. Is there a better way?
 
In the automation with the accessory, edit it and press the accessory button (press the right side of the button, not the left side with the icon) and you should get a percentage slider. Set it there, and it should work. Failing that, you could use a scene (again where the brightness is pre-set using the right-side of the accessory button)

If you're triggering with just the switch, then an automation "when the light turns on" set a scene where the light is "dim" is probably your best bet. It may kick in before the light reaches full brightness.

Hope this helps!

Thanks, making a scene seems to work better as there is no delay (there was a tiny tiny delay in my previous automation)

It seems kind of a fail of HomeKit not having some sort of default state though…
