I don’t have a stateful remote, but I believe if you ONLY use the Bond Bridge, it will properly track (discretely/independently) the fan and the light once you get it synced once in the real world + app.
As in, in the middle of the night if you tell the Bond app (or use the Bond + smart assistant integration to do a voice command) to set the fan to Low, and it is currently on High spinning Clockwise and the light is Off, Bond would send the state command of fan to speed Low, Clockwise + light Off (keeping the light off and fan spinning Clockwise).
Now, I think that would require you using the original wall control to get the fan + light in the same state in the real world as the Bond app thinks the fan + light are, and then not using the wall control anymore, and exclusively using Bond.
This struggle with hybrid use of original device remotes / wall switches + the Bond Bridge isn’t unique to stateful remotes, but it definitely seems extra ripe for things to go wacky and get out of sync between original control and Bond extra dramatically.
This struggle is exactly why I use API-integrated (as in, using the Bond API) third party 8-button remotes, Harmony remote hacks, and/or in-wall switches/keypads to give physical controls to rooms that Bond is controlling the fan and light (the original fan remote is locked away in a drawer, never to be used again haha).
