Update 01/27/2021:Cellar responded with specific instructions on how to proceed after an app update. The key was removing the existing Bluetooth device setting in your phone before reinstalling the updated app. Then once you selected the Bluetooth in the app only, not in your phone, The light settings begin to work again as well as the speaker.Update 01/22/2021:App is no longer fully functioning as only the music portion works, not the lamp. The remote control only controls the fan, fan speed, light on / off, and timer. Predemobile and colors are no longer possible without the app.November 2020:I had professionally installed free via my electric company's wire protection plan. It was short 2 screws, however he had the right type with him. Although I did find one on the ground afterwards, so don't be too worried since screw was easy to replace. Other than that, it works fantastic, once you figure out how to connect both bluetooth settings, separate one for music. It just takes a little patience, connecting them in their app, which is written in Mandarin unfortunately. I also plan to change out my dimmer wall switch for a regular switch as it isn't needed and should help it run smoothly and quietly. It has dramatically changed the ambience and comfort of my guest bedroom, soon to be a much needed walk in closet / dressing room and office. Now I'm tempted to get a recliner / futon to make it a resting space. It is also adjacent to 2 other bedrooms so we can appreciate the music and lights from adjacent space as well. I cast my Sirius music app to it and even the various scene settings work well, i.e. lights coordinate with music beats, colors softly / quickly change, etc. The remote control comes with a wall plate holder which I will hang soon so it doesn't get lost. It is similar to my Hampton Bay fan/light remote control. I'm so happy I chose this one, as the finish is perfect for the space. It was carefully wrapped to protect it from scratches and came with very small gloves to prevent smudges. The electrician was also impressed with the fandalier concept and product function itself.Everyone loves it! The only down side is that if the speakers and the light change can’t be used at once. It’s either the speaker or the light. If the light is in use, then the music plays through your phone.
