H801: Seperate ON/OFF for all Channels "RELAY_PROVIDER_LIGHT"

I'm trying to get one H801 work for different LED-Stripes, so it is necessary to control each channel separately.
At the Moment there is only ONE ON/OFF SW-Button witch powers all channels the same way. Additionally I would like to use Hardware-Buttons (e.g. GPIO0, GPIO3) for the old electric setting in my house.

My try to add 5 Relays and 5 Buttons in the hardware.h failed, because every Button on the Web Interface turns all 5 channels On/OFF as long as

#define RELAY_PROVIDER RELAY_PROVIDER_LIGHT.

Otherwise fading and dimming don't work.

Yes, that not how it works. If you check the _relayProviderStatus method in relay.ino you will see that for the RELAY_PROVIDER_LIGHT it doesn't care what button or relay was triggered, it will just send the status to the light module.

This will require a minimum change in the relay module and a bigger one in the light module to store the on/off status per channel instead of having a global "status" variable.

Is there a plan to enhance the actual relay behavior? At the moment it is possible to define relays and buttons and connect them e.g. to Alexa as power plugs. So, if I use a ligh controller (e.g. H801) and connect it to Alexa it is also a power plug, and the light-functionality (dimming) can't be used.
It would be nice for the future to add an additional relay-type (e.g. #define RELAY#_TYPE: RELAY_TYPE_LIGHT_BULB) where it is possible to connect these relays as light bulb with Alexa to use on/off/dimming. Additionally there is the question how to use a HW-button in this mode if pressed: turning on/off the "relay" or powering up/down the pwm. (for all channels or each channel separately)

I will give it a try. For the moment it's assigned to milestone 1.13

That sounds good. I'm curious about it.

Just pushed a preliminary support for this. This is how it works: basically, you have to define a number of dummy relays that matches the number of channels of your light. Then each relay will control the ON/OFF state of each channel. If you define one dummy relay more the first one will control all channels, just like now. Any other number of relays will make them behave just like now, they will all control all the channels.

Note these dummy relays behave just like normal relays, this means you can use MQTT also to control the channels.

This is kind of a hack so I wouldn't go further for the moment. Just give it a try and tell me if it's what you needed. It's in the dev branch.
