bond sees my Hunter fan light and provides buttons in the app that can be tapped to raise/lower the brightness. Each tap will raise/lower the brightness 1 step. I do not need to enter an absolute % to set the light to.
This is similar to the control Alexa provides for my television volume. I can tell Alexa to raise/lower the volume X times, which sends one or more signals for volume up/down.
So, we know bond can do this in its app.

Can’t bond use this functionality as a model to provide a fan light dimming capability?
