#Controlling QuinLED-Dig-Quad w/o Wifi (with smart relay)?

Hi!
I am planning some WLEDs using the QuinLED-Dig-Quad. I am a bit unsure if there is a way to use it in a "dumb mode" w/o WiFi in case the wifi/HA goes down?

For any other "normal/smart" lights I will have "dumb" switches connected to smart relays (DIN) and these connected to either dumb or smart lightbulbs. Here i know that with "Edge Switch" mode of Shelly relay i can either flip the switch to change the state of the relay OR change the state in HA, both will work.

But can I achieve this with the QuinLED WLED? Since there will be a power source which makes 240V -> 5/12V i can't (don't want to ) change the power IN of the PSU via the on/off of the relay because that would cause QuinLED to shut down/up every time the switch is pressed and likely cause delays in turning the lights on (as the QuinLED needs some time to boot and connect to Wifi).

The connection schema would be: DumbSwitch (or smart, but that is irrelevant here) -> Shelly SmartRelay -> 5V PSU -> QuinLED -> WLED strip(s).

Normal mode: QuinLED is connected to HA, so if i either flip the dumb switch or use the HA dashboard, i can turn on/off the WLED, no issues:

Wifi down mode: ??? Here i need some help. Consider Power and HA running, just the Wifi is down, so QuinLED gets disconnected. How to ensure I can still at least turn the light on/off (i can sacrifice any other controls like sections, dimm, etc...)

I see there is a "vEXT feature" which says:
`vEXT feature

  • Allows running the board with 2 power supplies
    -- Enables running off standby power (5v phone charger for instance) while main high-power LED power supply is switches off with a relay
  • Dedicated terminals for extra vIN, GND and relay trigger
    -- Relay trigger is 5.12v boosted (Q1R). Shared with Q1 pin`

But i am not trying to provide "backup" powersource, i need some sort of "hardwired" way of turning the light on/off...

Thank you in advance!

Wled will start up with whatever its default settings are.

I have one esp32 and one dig-uno powered off my landscape lighting transformer so they get shut down nightly. Sometimes they connect to wifi, sometimes they don’t. The only delay is the software starting up

If you want a dumb switch to power down the lights without affecting wled, put the light strip power supply behind the relay and keep wled powered fully with 5V supply

Ahaaa, okay, so the power goes on right away once the lighting transformer gets powered up, only the controller/Dig might have a delay. Meaning it works even with QuinLED-Dig not being configured at all -> Power itself is sort of a "pass-through" ?
put the light strip power supply behind the relay and keep wled powered fully with 5V supply
If i understand this correctly then the connection would be:

  • Dumb Switch -> Smart Relay -> lighting transformer (5V)-> LightStrip +/- pins //This turns the lights on/off
  • Another 5V power source -> QuinLED-Dig -> LightStrip DATA pin only //This is to control the colors, etc ... not sure about the brightness though?
