Grouping - Slave_id and Master_id are not seen in the summary

[MarkAlanJones]

"group": { "mode": "master", "uid": "05EA11E8-64E4-4D28-A0A7-0679CA5DA684", "compat_mode": 0

    There is now a Uid --- is this the name of the group ? 
    
    How is a Group Created ? (is there a RestAPI ? )

I see in the movie sync information that this uid is the master_id

{"frame_delay":66,"leds_number":190,"loop_type":0,"frames_number":60,"sync":{"mode":"master","master_id":"05EA11E8-64E4-4D28-A0A7-0679CA5DA684","compat_mode":0},"code":1000}

the slave has the same slave_id in it's movie sync information

so there is only one "group id" and it is known to the master and the slave.
so i guess when the master sends a udp packet, the slave only reacts if the uuid matches

the key doesn't have to be a uuid. Twinkly is simply saving a uuid in a text field.
That's a change twinkly made in a recent app version. It's actually annoying as heck as there's no longer a way to get the group name unlesss you scrape their web api.
