When with the original remote, you hold a button to dim, the Bond team has explained that it’s difficult to have an effective dimming strategy outside of the app. If the original remote doesn’t have a “brightness percentage” indicator or discrete commands to say, “set brightness to 30%” directly, a Bond bridge won’t be able to magically add that ability to the fan’s receiver, nor turn that fan’s receiver into a real-time state transceiver.
I don’t see the RF range this fan series uses in the documentation, but I do see it listed on Amazon as compatible with Bond, so someone should have tried it before marking it as such.
If you got a Bond Bridge and only controlled the fan (power and speed) and light (power and start/stop dimming) through the Bond app and integrations using Bond, there is a “trust state” feature you can use to have Bond track whether or not it turned on/off fan, or turned on/off light (said another way, using the Bond Bridge sometimes and the original remote other times will make any integration unreliable as to power and speed state); however, as explained above, the Bond Bridge will not know anything about current brightness level, due to sort of a weak point of the majority of RF based fan kits from manufacturers. Doesn’t mean you can’t attempt something utilizing X seconds of “send dim” commands through Bond controls within SmartHome programming, but I feel like most forum members with these kind of limited fans (myself included) cannot achieve reasonably reliable brightness settings.
