While you are waiting for Bond staff to see this message (you can also contact them via in-app chat or emailing customerservice@olibra.io), you can repurpose a button from a manually recorded fan device to be the color /light temperature changing command, and then rename it with the API to allow the name of the command which shows in the Bond app to make more sense.
It also doesn’t have to be from the LIGHT section of a manually recorded ceiling fan - could leverage an unused button from the FAN section since there are more in that group. For instance, if you didn’t need the Bond to be able to control summer / winter modes, or breeze (though yes, I think I see the original remote had those as well), you could record the color / light temperature toggle button as one of those.
It will help the Bond staff either on here, or when you contact them via app or email, to provide the FCC ID as indicated somewhere on the original remote.
