Allowing Multiple Alexa Devices to Allow Multiple Effects

Enhancements

There does seem to already be a post relating to this here, but it’s very confusing and seems to only include 50% of a conversation.

I hope that my suggestion makes it clear on what additions/changes I would like to be made to WLED. I have been able to do this already using espalexa, but it no longer seems to detect new devices whether I use a dot 1, 2 or app.

Basically, I would like to be able to define multiple names for the device and each one is linked to a specific effect so when you turn that device on it enables that mode. The initial setup would be something like this:

  espalexa.addDevice("Gutter", colorCallback);
  espalexa.addDevice("Rainbow Gutter", rainbowCallback);
  espalexa.addDevice("Rainbow Cycle Gutter", rainbowCycleCallback);
  espalexa.addDevice("Fire Gutter", fireCallback);

Then depending on whether it is a effect that allows colours or not, it may do this

void colorCallback(uint8_t brightness, uint32_t rgb) {
  Serial.print("Loading color preset with brightness ");
  Serial.print(brightness);
  Serial.print(" and colour ");
  Serial.println(rgb);
  loadPreset(color_preset, brightness, rgb);
}

or this

void rainbowCallback(uint8_t brightness) {
  Serial.print("Loading rainbow preset with brightness ");
  Serial.println(brightness);
  if (brightness == 0){
    ws2812fx.stop();
  } else {
    ws2812fx.setMode(FX_MODE_RAINBOW);
    ws2812fx.setSpeed(5000);
    ws2812fx.setBrightness(brightness);
    ws2812fx.start();
  }
}

Obviously this hard-coded method wouldn’t work for this project, but it shouldn’t be a huge addition to implement. In the settings, it could just have a load of tickboxes - one for each effect and you can tick maybe 5 of them. Each one would automatically add a new espalexa device with the name of the effect added before or after the device name and whether it supports colour or not.

What do you think?
