Hello,
Let me start off with I'm new to the forum and a bit of a n00b when it comes to driving LEDs so I hope I'm posting in the right place. I purchased some 15 watt, IP66 LED RGBW fixtures that I want to modify in order to control via WiFi with Home Assistant (www.home-assistant.io). I also bought some MagicHome type WiFi RGBW controllers to interface with since they use an ESP8266 (or esp8252 in this case) and are easy to load custom firmware.
Here's what I've done so far:
Before hooking anything up to the wifi controllers, I opened up the fixture and disconnected the LED array from the built in IR controller. I used an O-Scope (dds-120 USB scope) to check the voltages coming off the original controller. From the looks of it, the LEDS are getting driven at around 21 volts. I dimmed the fixture a little and was definitely able to see the individual pulses getting shorter. So far so good. I also was able to get the firmware flashed on one of the Wifi LED controllers and it is able to drive an RGBW strip I bought for another purpose so I know the flash was successful.
Now, here's where it gets confusing to me. The panel inside the fixture has 6 RGB LEDs and 30 white LEDs. The markings on original driver show + G R B W X (X is a marking I can't read) and there are 6 wires. on the connector going to the array. Where the wires solder onto the array the markings are V G R B W P. The RGB LEDs are obvious but what's throwing me off is that half of the White LEDs are marked W and the other half are marked P. There is also a line of 13 SMD resistors with 1 each marked R, G, and B, 5 marked W, and 5 marked P. In comparison, the RGBW controller only has 5 outputs (RGBW+). The controller is rated 5v - 28v, 192W.
If anyone could provide some tips or pointers to get these working it would be greatly appreciated.
Thanks,
Chris.
P.S. I tried posting some pics but the links keep disappearing. I assume it's because this is my first post.
