Updates on Groups require the the bridge to be restarted

[Muskelkatermann]

When I change the groupsettings with

• createGroupWithName:lightIds:completionHandler: or
• updateGroupWithGroup:completionHandler:

I have to restart the bridge (By unplugging the powerconnection) to make my changes take effect. Changes in this case are creating and removing groups and adding are removing lights to a group.

Example: I have a group with Light 1 and 2 and i can set the group state like On/Off that works fine.

Now I change the group: group.lightIdentifiers = [NSArray arrayWithObjects:@"1",@"2",@"3", nil];

And Update the bridge: [bridgeSendAPI updateGroupWithGroup:group completionHandler:^(NSArray *errors) ...

The bridge is updated correctly, Light 3 was added to the Lights Array. I can see that by calling: http://192.168.2.110/api/2beb86671081cadfa6d605712c826cf/groups/3/

When I send On/Off statechanges to this group only Light 1 and 2 are controlled. After I restart the bridge by unplugging the powerconnection Light 3 is controlled too.

I can create groups without any problems by

id<PHBridgeSendAPI> bridgeSendAPI = [[[PHOverallFactory alloc] init] bridgeSendAPI];
NSMutableArray *array = [NSMutableArray array];
[array addObject:@"1"];

[bridgeSendAPI createGroupWithName:@"test" lightIds:array completionHandler:^(NSString *groupIdentifier, NSArray *errors) {
    NSLog(@"Added group %@", groupIdentifier);
}];

but when I try to remove with removeGroupWithId nothing happens. Even the completion handler is never called. :(

Now deletion also works. I was storing the bridgeSendAPI in a weak property of my object and that seemed to be the problem.

Have you tried to use the group, like toggle the group's powerstate on and off?

I can create and edit the groups and change it's lightstate without problems. All changes i make to the groups are saved correctly in the bridge. But as long as I don't restart the bridge, the lights are not reacting to changes of the group's lightstate. Maybe there is an internal light / group assignment that is only updated when the bridge restarts?!?

Please not that using groups other than group 0 is not currently supported. See http://developers.meethue.com/2_groupsapi.html - section 2.1.1. If you are using other groups the functionality is undefined.

[kevintoms]

Please note that the bridge update to firmware that is being rolled out now, fixes this problem and groups other than 0 now work correctly.

[twam]

So the statement 'At present only a limited number of these APIs are supported in the firmware so only control of groups/0 is supported.' in the API documentation is no longer valid?

[kevintoms]

Yes it is only valid for the old bridge firmware. The API documentation will be updated to clarify this too.
