Dimming duration values not sent to bound devices when switching on/off

Best way is to remove the switch from HA, reset and rejoin the switch to ZHA and it’ll pull in the signature fresh.

I did more or less this, and it did the trick. Now I’m on v12.

Specific instructions for future reference:

1. Go to the device page, hamburger menu in the top left, and press Remove:
   
   This removes the switch and puts it in pairing mode.
2. Go back to the zha integration configure screen, press “add device”
3. When it shows up, give it the same name as before. This should preserve most automations that use it, but perhaps not all.
