I have two identical ceiling fans, ‘master fan’ and ‘kids fan’.
With the bond app, I can control both of them perfectly well, including fan functions (off, speed 1, 2, 3, off) and light (dimming, on, off).
Integrated with alexa, I get complete control over the kids fan (so “alexa, turn on kids fan light” works). However, with the master fan, Alexa claims sure, she’s doing it, but … no light status change. Fan works – “Alexa, turn on master fan” works perfectly fine. Just not the light.
