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.

UPDATE: Seller contacted me to solve my issue. After providing details of power supplies being used and troubleshooting efforts already completed on my part, it was determined that I had a defective unit. The seller is sending me a replacement as well as some other items. Seller was very responsive and helpful in resolving my issue. Changed from 1-star for original product to 5-stars for responsiveness of seller. ORIGINAL: It does not power the entire strip. It only powers about half the lights. The other controller I bought at least powers them all. I am also unable to connect to the controller using the app. It never detects a SP105E device in Bluetooth like the picture indicates.

4-Stars only because the instructions are not suitable. You will have to do some digging online and watch a few DIY videos if you are not familiar with this type product and are just beginning to dive in. I purchased this for a solar address light I rebuilt with a three-wire cob strip. In order to find the right configuration you will have to basically match the wires coming from your LED strip to the out ports on the controller. One thing that isn’t clear is that once you download and start your controller’s app, once connected to the device you will need to go into the app setup and select the correct type strip light from the built-in scroll menu. After tinkering with it I figured it out, works great but will have to return to update on durability, connectivity, and overall functionality over time as it is yet to be verified through use, and normal product wear. Overall product-wise rating as far as working is concerned for the time being: I say 5-star because it works!

This works but the app to control it absolutely sucks. Since that’s the only way to control these lights: this product sucks. The app always forgets the controller it has connected to, just presents a list of all Bluetooth devices so you have to guess which one you need and then is needlessly complicated setting the light mode. The engineer who programmed this is a loser.

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.

Cons: 1) 5v doesn't give a bluetooth signal strong enough to get more than a few feet away. 2) None of the modes are very useful as they are not defined. 3) No apparent way to make presets in the app. The results above were achieved when I hooked up to a RGBW SK6812/SK6812NW that I got here: https://www.amazon.com/dp/B01N2PC9KK?ref=ppx_yo2ov_dt_b_product_details&th=1 Pros: This is really just a tester for me and it functions adequately for that function. I had to have 12v input to the controller and a seperate 5v to the strip power to get decent bluetooth. 5v for bluetooth just wasn't enough power. If you do this, remember to strap ground from the controller to ground on the strip or the controller won't drive the signal to the strip. Overall C+ grade for me. Functional but not robust.

Once connected and configured, it works as it should. The app picks up the controller easily, and communication between the two is very responsive. Range is pretty good as well! Tons of preset modes for you to try and find what suits your liking. App setup is really simple. You set the pixels, RGB configuration, and LED strip type.

I've used WS2811 lights with the SP105E controller in a few different applications including signage, DJ setups, and pontoon boat lighting. I've had nothing but great luck. The LEDs are insanely bright and the color patterns are great. I find the app to work fine as long as you know to initially setup the controller for the lights you are using (and selecting the RGB order that matches your desired to actual outputs. Once setup it's ready to go on any phone. My only suggestion would be to setup the app so you could only have it find relevant devices, rather than all bluetooth devices in the area. One of my setups is in a busy dining hall and there can be hundreds of returns when the app scans devices. Just having it find the SP105E would be great.

Ho utilizzato questo controller per pilotare la cornice luminosa del mio smart mirror e devo dire che funziona egregiamente, ha un gran numero di effetti RGB e si controlla facilmente dallo smartphone tramite l'app dedicata. Attenzione può controllare solo determinate strisce led RGB, verificare bene prima dell'acquisto.

Funktioniert super für meinen ws2812 Led Strip. Einfache Bedienung und schnelle Verbindung mit der App.

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

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

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 .
