Regression: Power relay stays ON when HyperHDR turns off LEDs (0.0.4 → 0.0.5)

[TheFreizh]

Description

On firmware 0.0.4, turning off HyperHDR would turn off the LEDs and also cut the power relay pin (which controls the LED strip's power supply).

On firmware 0.0.5, turning off HyperHDR still turns off the LEDs, but the power relay stays ON — the LED power supply is not cut anymore. I can also see in Home Assistant that the Hyperk toggle stays "on" in this state. I have to manually press the toggle to actually turn off the relay/power supply.

Steps to reproduce

Flash Hyperk 0.0.5 on an ESP32-C3 board with power relay configured
Connect it to HyperHDR
Turn off HyperHDR (or stop the stream)
Observe: LEDs turn off, but the relay/power supply stays on
Check Home Assistant: the Hyperk toggle still shows "on"
Manually toggling it off in Home Assistant is required to actually cut the relay

Expected behavior

Same behavior as 0.0.4: turning off HyperHDR should turn off the LEDs and cut the power relay automatically, without needing a manual toggle.

Environment

Board: ESP32-C3
Hyperk firmware: 0.0.5 (previously 0.0.4, where this worked correctly)
Downgrading to 0.0.4 (factory flash via esptool) restores the correct behavior
Integration: HyperHDR + Home Assistant (WLED API compatibility)

Hi
Does the stats shows Effect source and you set default color to 0,0,0 (exactly)?

[TheFreizh]

Hi,
Thank you for your quick reply.
Yes, the default color was 0,0,0. I didn't understand what you meant by "Does the stats show Effect source", but I saw that the "Default Effect" option was set to "Rainbow", and changing it to "Solid color" seems to work.

Ah, "Rainbow" is not implemented yet but it would not work with the power relay anyway (always "on" for the animation) ;-)

Ah ok, sorry for the inconvenience, and thanks for your amazing work :)
