[FEATURE] Add qrcode for Bridge

[Shaquu]

Idea is to add generated qrcode to join Bridge just like in Homebridge.
From what I see it's sort off provided in HAP-Nodejs as Accessory.setupURI()

We have to find out where in UI we can show this qrcode.

I would like you to:

1. Vote with emote hand under this post
2. If you are against then please provide some arguments so I can understand why :)
3. If you are for idea then please provide some ideas how can we make it!

Would be REALLY cool if this could be provided in the debug panel on nodered.

Each time it’s deployed you could send a debug message with the code.

I have no idea if this is possible.

[Shaquu]

@crxporter I like to say that everything is possible.
So we have first idea to place it in the node-red debug panel.

Would be a really good feature. Also a good place seems to me the info panel of the node properties. But I guess this is static content? If the QR code becomes too complex what about the numeric code placed on so much home kit accessories for scanning and recognition

[radokristof]

Or maybe if you connect an URL node or some other nodes to one of your nodes in that bridge it should show that qr code on a specific website? Like http://ip_adress/homekitsetup. I don't know if this is possible with Node-RED

I like the idea of a homekit uri (we have ui for the dashboard stuff), for now it can just display the code + QR code, but the generic name allows for adding other things later.

For now I have made badge like this:

I based it on Homekit set up codes from the internet.

Cool! Have tried a camera scan with iOS and it redirects me directly to the home app ;-)

@Shaquu This is how a HomeKit badge/sticker looks like on a native HomeKit device :) This looks really cool if we can get it working somehow.

[Shaquu]

@djiwondee happy to hear it works.
@radokristof yes we can!

So once more. Where should we place this badge?

[djiwondee]

@Shaquu to me that would be the right place:

So once more. Where should we place this badge?

[radokristof]

@Shaquu do we know when a bridge is succesfully added to a Home? If yes, we can place this badge on the Debug panel as others suggested until the bridge is succesfully added. However if we can make a simple webpage displaying only just this badge (and a little footer text to scan this qr code), that would be the best I think. Mainly because it can be viewed in almost full screen (just think about small screens, or high dpi screens).

I think the issue is that many of us have/will have many bridges.

It needs to be easy to find or we will just use the old method of typing 111-11-111 every time...

What about a persistent set of node-red errors/warnings? Can it be placed there? Or at least a link there that says something like "successfully deployed, click here for the qr code"
