Ok, so if my thinking is correct I’m a bit out of bounds here but I’ll take a swing in case anyone might happen to have any insight
I’m looking to find out if a WLED/NodeMCU (or another controller) could support outdoor landscaping LED lights/lamps that I’m about to install which includes these Par36 LED lamps (Input Voltage: 8-25 VAC/DC/60Hz)?
- This light appears to be supported by this controller, but of course I’d like to use custom firmware like WLED/NodeMCU
- I’ve read about this controller which appears to be rated to handle up to 20A total (5A per color (red, blue, green, warm white, cool white) and that I can wire into just the WW channel which is all I want and I know I can install Tasmota on it to meet my custom firmware requirements, I just don’t know enough to determine if this, or some other controller/custom firmware would work?
Thanks as always for any feedback 
The “Chameleon Series Setup Instructions” document leads me to believe these lights are entirely wi-fi controlled. Each light seems to have it’s own built-in controller, and they all communicate on your home wifi network with a mobile app.
I believe this means that both of the controllers you sent are superfluous for those Brilliance LEDs. The first one looks like it’s meant to add wifi control to a 110V socket, to be used on a “dumb” light, or to control the transformer that is powering all your lights at once. The second controller is meant to add control to (I think non-addressable) LEDs.
The problem is that, out of the box, those lights are only going to want to talk to their app. This can maybe be made to work, depending on how much effort you’re trying to put in and how lucky you get.
The basic idea is that wled can be configured to send sync information in a few different formats. It may be that these lights support one of those formats, but they might not. Best way to find out is to get one and get testing! Here is the first of several pages that describe these sync interfaces, I’d recommend reading through those to try to build up some background information (or at least get an idea of what you’re getting into)!
Hopefully someone with some more first-hand experience using the UDP sync protocols will stop by and help you out! If it is uncovered that this cannot be achieved via sync protocols, the only realistic options I would see is to either try to flash wled onto the Chameleon controllers (which may or not even be possible, who knows what their hardware looks like) or to modify each light to remove the existing controller and install an esp with wled on it (which is a non-trivial amount of work).
Insightful as always, thanks @mjg1088, you’ve given me a start. I’ll dig in a bit more and see what I can discover
