RE: Zigbee Group ID Generation

Hello Edvin,

I have tested this out, and can confirm that using a bulb's 16bit short address works just fine for setting group IDs.

In terms of the switch knowing the group ID, I am maintaining an internal struct which keeps track of found devices and their associated groups. It works well for its current purpose.

Thank you very much,
Angry Oatmeal

Hello,

[quote user=""]Is there a specific format or range that group IDs must follow in order to be valid (other than being 16 bits long)?[/quote]

I don't think there are any limitations.

I don't think the group IDs and the short addresses are using the same "space". They are different sets of IDs. Do you get any issues when using the first light bulbs address as a group ID?

What you need to think about is how the light switch(es) will know about this group ID, and where to send the messages. Is your coordinator handling this?

BR,

Edvin
