BTF-LIGHTING Wireless Bluetooth Controller SP105E iOS/Android APP for WS2811 WS2812B WS2815 WS2813 WS2801 SK6812 WS2815 SK9822 APA102 etc LED Strip Pixel Fairy String Module Panel Light

I initially encountered issues with this controller, but all is well now! I am using the BTF-Lighting 5VDC 20A power supply which does not maintain 5VDC under the load of a 5m LED strip. When voltage drops to 4VDC this controller will not respond. (This is likely not be a concern when using 12VDC LED strips.) I was able to work around the low voltage issue by powering the controller from a separate power source -- I happened to have a 6VDC power supply with correct polarity on the barrel connector. I disconnected the red LED strip wire from the controller VCC and connected the spare power leads from the same end of the strip to the power supply (white & green to the controller, white and red to the power supply). Using this controller with a SK6812 RGBW (natural white) LED strip, I am able to select any static color for the entire strip, including RGB white and natural white. There are also 200 light patterns from which to select the effect of chasing lights in multiple color options. The brightness and speed of the selected color or pattern can be adjusted. Under 'settings' you can specify the number of pixels you wish to have lit. I've seen it mentioned to always select 2048, but selecting more pixels than you have on the stip only causes the pattern speed to slow down.

Works great. I am powering 5v ws2812b’s with a 12v power bank using a step-down converter. The controller gets 12v power (saw other reviews that seemed to indicate 5v to the controller was unreliable) . I split the ground and positive wiring before the controller, also routing power and ground through the step-down, and a capacitor for the 5v lights. Everything works well! (Yay, bc this is my first time working with LED’s) The app works great (restart your phone after install) and it seems there are other apps available that are compatible with the sp105e controller. There seems to be a few different directions included with this product as how to send power to your lights using this controller. I tend to think some of the bad reviews are from people who didn’t have the wiring done correctly. Almost did not buy it, but happy I did. I would recommend doing it right by drawing yourself a wiring diagram and soldering all your connections.... but wtf do I know. I’m an Industrial Designer/ Fashion Designer, not an Electrical Engineer. I do know my client is going to be pumped when they receive their LED wearables project with bluetooth controls!! Adafruit and Stack Exchange are excellent resources for those playing around with LED’s.

Be sure to download the correct app: LED Chord - the wrong one is listed somewhere. Works as described, although the app is pretty amateurish - you have a spinner that you have to rotate to access all of the patterns. Why not just a numeric entry field you can type into, with +/-1 and +/- 10 buttons? Even better, since most patterns are just repeated with a different color, give me one control to pick the pattern, and another the color variation? Then I could select the pattern 10x faster. Also needs a favorite/memory function to store your favorites in a short list. A notes field would be a bonus. As others have noted, eventually the app disconnects from the lights - WITHOUT ANYNOTICE. No amount of refreshing the device list will fix it. This probably leads to most of the negative reviews come up and returned devices because people just starting with it think it's broken, not realizing the connection has failed. The only solution I found was to go into the android task list and kill the app. Then when I reopen it and re select the 107 device, it reconnects again, quickly.

I wasn't expecting a lot from this controller so it exceeded my expectations. Great starter unit. Has about a dozen good light patterns in various color combinations plus several music settings. The mounting ears split when I screwed it down but otherwise was OK. It handled over 100 feet of WS2811 LEDs connected to a 300 watt power supply. Bluetooth connection is a bit finicky but Android app works fine. Not much control over lighting but for the price this little thing was impressive. I haven't found anything with a better reputation without spending a lot more money. Better than "good enough".

Bon fonctionnement, facile à mettre en œuvre et à utiliser.

Works Great the app was easy to setup no problems other than on my phone the app does not display the brightness setting but that is probably my cheap old pone the app worked on my pad . These are 200 selections for effects i am using 5v strip so added a 5v 10a power supply and that easily runs 5 meter lights .

Super practico y facil de enlazar con el movil y con diferentes tipos de magic led incluso de rgb normales

Ce contrôleur de Led est très simple d'utilisation et il y a un nombre incroyable d'effets intégré dans l'application

Bargain just buy it. High quality. Despite some bad reports I find this brilliant. Having gone through 3 of the tiny it controllers I wanted something more permanent. Works brilliantly with the magic led app on my android phone. 1 minor issue : doesn't pair up with Google home app. Who cares, apart from that works flawlessly. 5 🌟🌟🌟🌟🌟
