Multiple Accessories

[rooi]

Hi KhaosT,

I would like to add more accessories to the hub. Could you give some tips on how to achieve this?
I've tried a couple of this and concluded that the target port for accessories need to be 2 apart to account for the read and write (+1) port. Besides this, my guess is that the serial numbers have to be unique.
Are these assumptions correct? Are there any other things I should keep in mind? Please note that I'm quite new to NodeJS etc.

With my try now I get the following error after I try to add a second accessory in the HomeKitDemo app.
buffer.js:188
throw new TypeError('First argument needs to be a number, ' +
^
TypeError: First argument needs to be a number, array or string.

After this I have to restore HomeKit on my phone to get the first accessory working again.

Hopefully you can give me some pointers in the right direction. Thanks again!

There are two ways to do this.
First approach, If you follow HAP's Bridge-Accessory Model, You can rewrite AccessoryController.jsonPresentation. In that dictionary, instead of returning a single accessory, you return multiple accessories with different AID.
Second approach, Under Core.js, create multiple Accessory instance with different Username("1A:2B:3C:4D:5E:FF") and its own accessory controller. This approach will requires HomeKit on iOS to pair with each accessory you created.

[rooi]

Ah, thanks KhaosT. I tried the second approach but probably did something wrong. I'll try the first approach tomorrow or retry the second one.

@KhaosT awesome work you are doing with HomeKit!

I have a question related to this. I noticed in Core.js, when the lightServices is created, a type identification number is given "00000043-0000-1000-8000-0026BB765291" (at least I suppose that is the light type identification number).

In case I want to create services of other types than "Lightpulp", where can I find a mapping of service type identification strings to the service types.

Such as...

HMServiceTypeLightbulb
HMServiceTypeSwitch
HMServiceTypeThermostat
HMServiceTypeGarageDoorOpener
HMServiceTypeAccessoryInformation
HMServiceTypeFan
HMServiceTypeOutlet
HMServiceTypeLockMechanism
HMServiceTypeLockManagement

[KhaosT]

@arnthorsnaer on iOS you can do a NSLog(@"%@", HMServiceTypeSwitch); to get the UUID you want :)

Hi KhaosT,

I'm still working on this and learning NodeJS and some HomeKit in the meanwhile. Just a quick update.
I've tried both approaches, but we unsuccessful until now. Using both approaches, the accessories are displayed in the app, but adding them does not work.
Perhaps you can give some more pointer? I'm working on the first approach (rewriting the AccessoryController.jsonPresentation) right now. I have one accessoryController in the Core.js and add different service for different aid's to it. This seems to work ok. But do I need multiple accessory_Factor.Accessory(), var storage, and .publishAccessory with different port numbers or not? Could you give some more information?

Below is a snippet of the Core.js code I have, perhaps this illustrates some of the problems I'm running into. Hopefully you can provide some more assistance. In either case, thank you very much!

Roy

// Funnel
console.log("Adding funnel");
var storageFunnel = new require('node-persist');
storageFunnel.initSync();

//var accessoryControllerFunnel = new accessoryController_Factor.AccessoryController();

var infoServiceFunnel = accessoryFunnel.generateAccessoryInfoService(service_Factor,"Light Funnel","Rev 1","A1S2NASF88EW","Nlr");
var lightServiceFunnel = accessoryFunnel.generateLightService(service_Factor);
accessoryController.addService(1,infoServiceFunnel);
accessoryController.addService(1,lightServiceFunnel);

var accessoryFunnel = new accessory_Factor.Accessory("Light Funnel", "1A:2B:3C:4D:5E:FF", storageFunnel, parseInt(51822), "031-45-154", accessoryController);
accessoryFunnel.publishAccessory();

// Greggs
console.log("Adding greggs");
var storageGreggs = new require('node-persist');
storageGreggs.initSync();

//var accessoryControllerGreggs = new accessoryController_Factor.AccessoryController();

var infoServiceGreggs = accessoryGreggs.generateAccessoryInfoService(service_Factor,"Light Greggs","Rev 1","A1S2NASF88EV","Nlr");
var lightServiceGreggs = accessoryGreggs.generateLightService(service_Factor);
accessoryController.addService(2,infoServiceGreggs);
accessoryController.addService(2,lightServiceGreggs);

var accessoryGreggs = new accessory_Factor.Accessory("Light Greggs", "1A:2B:3C:4D:5E:EE", storageGreggs, parseInt(51824), "031-45-154", accessoryController);
accessoryGreggs.publishAccessory();

I tried the second approach and it worked great for me... Here is the modified version of Core.js I used.

[rooi]

Hi KhaosT,

Thanks for this example. It worked instantly, and tried to apply the second approach to my situation once again. This try it did work! I'm not sure what was wrong initially, but I probably made some beginner nodes error... Well thanks for your patience!

[quiquoi]

I just watched the edited file for 2 accessories, it's good

but after that I see is two lights then how to add such an outlet or switch?

[KhaosT]

@quiquoi You can modify the accessory service type UUID :)
