Hello,
Recently I had an idea of connecting Athom controller with relay and ESP32 with WLED 0.15 to analog CCT lights, specifically Auxmer CCT 24V. Controller currently successfully controlls WS2805 light strip and now I wish to add analog CCT strip to it. I looked online and, from my understanding, it should be possible, I just need a few tweaks (or so I think).
So Athom controller can run 4 channels and all of those 4channels can control addressable led strip and can be reconfigured in WLED. That was good news for me, since I could use 1 channel to control WS2805 and 2 channels for CW and WW of CCT strip.
I have also bought power amplifier with MOSFETs as requirement by WLED to control analog strip. More specifically power amplifier A212 (black metal box, and I have made sure it has MOSFETs and it has 2 of them, don’t know if that is ok, but it is specified as a WW and CW amplifier).
Then I have added connection from Athom controller to the amplifier:
- VCC —> V+ input
- GPIO 18 —> CW input
- GPIO 17 —> WW input
I have also connected power supply directly to the amplifier to power input and connected CCT strip to amplifier output.
Then I have powered up my setup and everything lights up just fine. I went to LED settings and selected PWM CCT led and assigned GPIOs 18 and 17 as LED controls. GPIO 5 is for existing WS2805 run. I left everything else at default, as well as other settings except I have checked that it creates segments for each LED strip.
And here is where my problem arises. When I try to control the analog strip, nothing happens. no brightness changes, no temperature changes, nothing. I see only two control settings, brightness and temperature (as I suppose I should have) but when I change them nothing happens. Also if I change global brightness, only my existing WS2805 strip changes. And yeah WS2805 works just as before with no problems, when I try to control its segment separately or both together. The only thing that seems to work with the analog strip is when I turn off lights, when relay clicks to change its status. So on and off works (I assume VCC line gets disconnected physically and hence amplifier shuts it of or something).
I have also tried to isolate problem and could not find anything that would be faulty. I have connected just the CCT strip to the controller and amplifier, changed GPIOs, connected strip directly to the controller, using only CW and WC lines from controller to amplifier, removing power supply to the amplifier (light does’t turn on in this case)…
I’m lost and would be really glad to get some help. I would also try to exclude option of getting a controller just for analog strip, since my smart home network already has too many devices and not many controllers have relay…
Thank you for any help.
