Extend the life of your LED Power Supply | WLED + Relay + DigQuad

[@AdamWelchUK]

For me (as a home assistant user) I think a small usb power brick powering the esp32 and a normal smart switch on the power supply is the way to go. Automation - when WLED is on, smart switch is on. Now we’re not messing with mains electricity and still saving the most power.

Another option is an old PC Power supply, as long as it is ATX. An ATX Power supply can supply a standby 5V line, which runs your ESP device, but low power consumption. The ESP can trigger the power on signal directly as the power on wire just needs to be pulled to ground, no significant current draw from it, to turn on the power supply. I've run my LED's with wLED like this for a long time and it is probably more power efficient than a separate power supply as an ATX PSU draws very little in standby, but can crank up the amps when fully powered up.

[@ZenMinus]

There is a potential minor problem with the first solution. If the fan is running, it needs to cool the PS components. Regularly switching off the PS when the fan is running allows HOT components to remain hot as the fan is switched off. This heat may destroy or shorten the lifespan of internal PS components. (Just a thought) 🙂

[@JonathanRootD]

Just don't push your ps beyond 80% rated capacity. Should be no problem.

[@Claudiu.]

This was actually the first thing I researched once I got my dig uno. I was very happy thst there's a pin available to do that and it's documented by Quindor with both options (interrupt just output to the LED strip - vs - separate power supplies and stopping the AC). I went with this separate power supply option and very happy I did so. Nice that you made a video about it.

If I use a 5v power supply with constant power to these three terminals. And then have my 12v power supply hooked up to a wall switch to power off. Would this allow me to keep the board running and then power of leds via the switch?

[@jonathanrollins2470]

I believe cycling power also causes stress. When a component heats and cools the causes stress/wear. Some things actually perform well running at a constant load. Think highway miles vs city miles on a car.

[@theaustindude]

Is there a way to do this if I'm already using the green terminals on my Quad for a 5th circuit?

[@billfoster6809]

Upon trying this out I find my only 5v relay board is a piece of crap that only triggers when pulled low. It has a jumper, but the jumper only disables the relay coil completely, rather than switch it to a high level input. In the video DrZzs shows leaving the GPIO 15 set on invert. Un-checking the Invert allows my relay to function.

Hey DrZzs I didn’t see this question in the comments… Is there a way to delay the relay from turning off the power supply? The reason I ask is that if the power supply fan is running, it means that the PSU is still hot! And turning the power off while it is trying to cool down may also shorten the life of the power supply. David M

[@_tim]

I get what you're saying but there's ultimately from the power supply's perspective there's no difference with the relay solution here, vs simply pulling the inbound power plug out of the wall. Either way the power is cut off and it will passively dissipate the remaining heat. If this is a concern maybe some active cooling like a fan or case fans in the enclosure on a separate power supply may be needed to keep moving air around the PSU?

[@MooreWoodWorks]

@@_tim I agree with your response if you simply pulled the power plug out of the wall. However, that’s not what happens when you turn off your lights via the WLED app. Doing that only stops the lights and the power supply continues to run (hence the subject of this video). My point is that pulling the plug from the wall -and- leaving the PSU running BOTH may reduce the longevity of the psu. Which is why I suggested a delay of the psu shutdown. However… That being said. The power supply will likely outlive the lights, controllers, wires, connectors, etc. The lights and controllers because of obsolescence. And the rest due to corrosion. So I guess that answers my own question.. -lol Good day @Tim 👋

Hi Can we use a Mosfet instead of the Relay?

[@PoisonWaffle3]

This definitely makes a lot of sense on a DigUno with a single power supply (switching power to the LEDs rather than the DigUno). I have two questions. If you have multiple strips fed from a DigQuad, is the relay is closed if any/all of them are on, and if it only opens back up when the last strip is turned off? I could see that working well when controlling the primary power supply with a relay. Also, is the power saving as drastic on 5v LEDs like WS2812 or SK6812? We know that 12v WS2815s are inefficient because they use resistors to get the voltage down for each LED. Thanks!

[@IntermitTech]

Let me jump in here. Yes, WLED intelligently turns on/off the relay. So if you have multiple strips/ports/segments once 1 goes on, it'll turn on the PSU and only once all are off, it'll turn it off. Regarding power draw, all LEDs generally use about the same idle current, ws2815 isn't too much less efficient in this case (uses internal regulator) vs ws2811 resistor or regulated version.

[@whatsupwithsteve]

Why not just hard wire your power supply to a light switch and just turn off the switch? I love playing with relays but they just seem unnecessary in this application? My other question is; I run 90w uncooled power supplies on my lighting and never need to run a fan to cool them off. Why is your supply needing such cooling when running

[@DrZzs]

The benefit of the relay is that it turns on and off through the WLED UI. You certainly can use a light switch, you’d just have to switch in on/off manually. I would be curious about the power use of those power supplies you’re using when the LEDs are idle. Fan or no fan, it likely would benefit from being powered down completely when it isn’t required.

[@whatsupwithsteve]

@@DrZzs Thanks for your reply. I have the undercabinet lighting tied to a wall switch so when it is off there should be zero power to the ss. transformer. I am enjoying your exploration of amps in the led world. I come from a pretty basic electric education of amps equaling heat and I have a hard time wrapping my head around these 18ga wires handling any amount of current..:) My guess is it's overall "power" that the primary concern due to the low voltages?

[@canadave]

Question: I'm planning on hooking up some WS2815 12V LED strips to a bare metal power supply like the one in this video, but the power supply will in turn be connected to a Meross smart plug that I can turn off and on using Alexa. So if I were to turn the smart plug off, that would cut off power to anything "downstream"--including the power supply that supplies power to the LED strips. Do I still need a relay in this situation?

[@leighhargreaves4104]

Yes, this is solution avoids needing a relay. The thing with this solution is it depowers the controller, so you're rebooting it every time. The question then is what does is WLED's default behavior on boot up? By default I think when you boot up the controller it leaves the lights off. However, I think you can program the controller so that WLED will run an effect on boot as default. I think the only downside is you can only set one effect (at a time) that you want at power on, it won't do a "run last effect" or anything dynamic like that. But that limitation aside, the solution does work.

[@Jeroen_a]

What about just using the sonoff basic? And set it to hold the button to stay on (instead of toggling when pressed) at least you have got a nice cover for it and you might be able to share the 5v of the sonoff as well. Or would that not work, since the 5v of the sonoff is basically always on? As a bonus you might be able to create a switch in homeassistant that you can toggle at will :)

[@ianclarke4182]

After failing to get WLED working on a v1 Basic, I'm going to use a d1 mini for WLED and power it using 5v from the Sonoff.

[@sirgoodenough65]

The sonoff basic has a mains switch. It will work if you use the sonoff basic to power the LED Controllers supply, but it will not accept the wLED firmware and actually work. Several reasons. The power supply is just big enough to power the relay and the esp. Hardware connections to the relay and button are not configurable. etc.. etc.

that's a great question. I don't think it regulates the voltage that goes out to the pixels. Why so much variability from the power supply? The pixels will probably be fine with the fluctuation for a while. The low end might cause some dimming or data problems at the ends of the line, and the high end may cause some extra heat in the pixels and may lead to some failure at some point. Maybe the thing to do is get a more stable power supply if you can.

it draws 15amps of 240v? the 5v/9v/12v side is a controller, it just powers the control circuitry for the relay. Its rates to 10 amp 250vac, 10amps 125vac. If you're using an power transformer to turn mains voltage into 5v or 12v, and you have the relay turning off the mains supply to that transformer, then running say 12v 10amp transformer will only be consuming 120watts of power. for a 240v mains supply that is half an amp, or a bit more depending on the transformer efficiency. You would be pulling closer to 10 amps if you had say a 1700watt 4 slot toaster that would be pulling 1700/240 = 7 Amps or mains voltage. So unless your lighting system is a space laser visible from the moon i think you should be okay. You would have to be running 2400watt of led power supplies, which would be the equivalent 200Amps of 12V worth of led transformers to all on one relay to technically exceed the relays limit.

same. Q1 is GPIO15 on both.

@@DrZzs In an adjacent room when someone turned the ceiling fan off it would turn a few LEDs on my DigUno (ver2). I set up a relay on the power side of the LEDs. Found out that I had to set the GPIO relay to 5 rather than 15. Now it works perfect!! Thanks for your tutorials!!

Why

[@TonyPham-Creations]

I'm using 3x Dig-Octa boards & somehow its not pulling any current when LEDs are of

[@MrSupersidewinder]

Why not keep it simple and just turn off the sonoff plug... DONE.

The only issue is that wLED Integration in HA will complain when the controller is off. Not the end of the world, but if you look at your dashboards as much as me that is a nogo.

I added vscode via docker compose, any help configuring ssh connection would be greatly appreciated... Terminal in vscode shows me as user abc@2f69326953... HELP!!!

I really can't help you in this forum. Come over to DrZzs Discord and ask. We should be able to help you there. Join the DrZzs Discord Chat - discord.me/drzzs

what 5V ext power source was used it the video ?

[@DrZzs]

any phone charger will do. The relay needs very little power. 0.5 amp or bigger is sufficient.
