Purple - 4 lights

[nigels0]

I assembled one of these glorious devices, the assembly seemed OK, it’s showing up in HA as a voice device and the logs look normal - though isn’t working. It is WiFi connected and starts up OK.

What do the four purple lights mean? Where am I going wrong!

thanks for a great project!

The 4 purple "blinking" lights (not really binking, but rather with random intensity) mean it's listening for wake word.

Could you please ellaborate a bit on "it's not working"? What have you tried? What are you expecting it to do?

[nigels0]

Well it isn't blinking - just a solid four sets of purple lights.

On powering on, it goes white, then flashes green for a while then just the four purple lights. I've connected it to HA (it seems OK) -

I'm trying to set this up to use OpenWakeWord (the voice parts otherwise work fine from accessing via Assist on my phone. Pressing near the four purple lights doesn't do anything, though volume up/down is working fine.

So even when you press the top, the volume tabs, anything at all, the logs don't register anything?

Make sure the physical switch is not set to Mute. Try toggling the "Use wake word" virtual switch in HA.

Although, the main issue that all your lights are solid purple. I don't think there's any case in which the config makes all top LEDs turn solid purple. Could you paste the entire config you used, too, please?

[nigels0]

**definitely purple!

The lights go briefly white to show the volume level - then back to four purples!

Please format the code properly.

[nigels0]

Sorry. Done.

[tetele]

Ah, now I get it! I suggest you either update to the latest version of my config or request support from the guy from where you got your config :)

Unlike Mark, I actually keep it up to date, because I understand what's there since I've written it myself.

[nigels0]

yes, that fixed it thanks.
