LED strip lights

hello all

this is my first post and am not sure where to post so I’ll start here. I am trying to control 2 zones of LED strips that will have 2 separate power supplies. I am unable to hard wire them together, but I would like for them to function as one. In each zone there is white and blue and I would like to be able to control each color separately and have dimming function. I have a generic Chinese led controller with wifi dongle and it works, but only for 1 strip on 1 zone. Can anyone point me in the right direction?
Thank you
Kyle

Hmm. I know it’s a bit disheartening to post a query that gets zero replies, so…

I have no idea.

Dunno how they’re controlled, what “generic Chinese controller” it is or what it does, etc. Maybe throw in some more details?

I ‘m also interested about solutions to manage several RGB led strips in sync.

So far i installed one under a sofa and would like to have a second one under another piece of furniture. Same situation with two power supplies and two RGB drivers, each with a remote. Even though i choose RF drivers, sometime one remote will affect both strips, sometime not and they get out of sync – different colors…

I guess the only reliable way is to have a single driver and both strips connected, which implies to run wires from one to the other, which is often unpractical.

Would mi-light controller be what you need? I don’t have one…but consider buying.

I have seen some YouTube videos where people are using amplifiers to control several RGB strips in sync.

Maybe an Inline RGB LED Strip Controller

…well, that’s what a “RGB controller” is. As cheap as a few dollars with a remote, IR, RF or even Wifi. The problem is keeping two of them (or more) in sync.

Consider hiring an electrician. And make sure any cheap Chinese power supply is mounted inside a fireproof electrical box, not just tucked up into the attic insulation out of sight.

Inside a cheap eBay LED power supply. (With arcing flaw.) bigclivedotcom Published on Feb 15, 2018 This fairly common power supply has a very silly flaw involving the choice of assembly hardware. It also has what I would describe as just-acceptable separation of tracks with no anti-tracking slots.

I pm’ed Vegas LED Fan who is into multicolored led strips – in liberal and multiple length. Here is what he says:

Quote:

I have used the RGB relays to connect strings of lights that were too long to control with a single controller. I do not know of any way you can synchronize two strip controllers without connecting them with a 4 conductor wire and using the RGB amplifier. The amplifier allows you to use the signal from the first strip while injecting power from a second power supply to the second strip.

I do have a workaround that will let you turn two strips on and off in tandem but also allow you to turn each strip on and off individually so as to synchronize them. The strip controllers keep the last controller setting so turning them on and off individually will not change the light color. This works if you are using 12V RGB strips.

You will have to purchase two 433mHZ wireless relays ($1.89 US$ on eBay) and either one hand-held or wall mounted controller ($1.89 or $8.33 on eBay). The relays can be programmed to turn on and off with up to 16 sources. I would program both relays to turn on and off with button “A” on the four button controller. Then program relay 1 to turn on and off with button “B” and relay 2 with button “C.” That way you can control both relays together or separately. I would do this so you can turn off either relay to synchronize either strip with the other strip. Once you get the color you want in both strips turn both on with “B” or “C” and use“A” from then on. If they accidentally get out of synchronizing, just reset them.

Here are sources for the parts on eBay:

wireless 3 gang wall mounted switch https://www.ebay.com/itm/Wireless-3-Gang-Touch-Screen-Smart-Home-Switch-… $8.33 postpaid This is a “smart touch wall switch” that you can mount anywhere on the wall. I used a couple of these to control lights in my home. It’s a battery operated switch slo there is no wires between the switch and house wiring.

Bottom line: to have several strips synced they have to be physically connected via an “amplifier” if need be.

However, several strips can be turned on or off simultaneously by using remote controlled relays.
