JN5168 - Zigbee multi endpoint dimmable light

[peeveeone]

Hi, I am in the process of creating a multi endpoint dimmable light and have been using a JN5168 and the JN-AN-1171 demo project as a starting point. Overall the results are great, the device connects to the HA network and all (4) endpoints/lights are discovered and controllable. However, there is one issue I have been unable to resolve:

When more than one endpoint is assigned to the same group, only the first endpoint reacts to group commands, scenes do work as expected. Some examples:

- With all four lights individually assigned to a group, all lights react to their group command

- With the four lights assigned to the same group, only the first light reacts to group commands

- With the lights assigned to two groups, only the first light of the group reacts to group commands.

I cannot find anything related to endpoint group assignment and handling in the (cluster) documentation and by looking at the SDK sources I can only assume it closely related to scenes.

Can anyone point me in the right direction?

Thanks, Peter.

Hi Peter,

The Controller device can operate the Lighting device(s) using one of two addressing modes – unicast or groupcast. Unicast mode allows the user to operate a single Lighting device.

Groupcast mode allows the user to operate a group of Lighting devices simultaneously.

Use the button ‘?’ to toggle between these two modes.

What is the Shift Mode that you are using?

 Please take a look the The four tables summarise the button functions in the four Shift modes.

Hope it helps.

Hi Mario, 

Thanks for your reply. While this was not the direct solution, while reading about the Groupcast/Unicast I found out about the queueing system used for messages. Increasing the appropriate queue size turned out to be the solution, everything is working fine now.

Thanks. Best Regards, 

Peter
