Once the different Twinkly have been connected to the home Wi-fi network (see How can I connect Twinkly to my Wifi network?), it is possible to create a group of devices up to a maximum of 4 and Join them so that they are seen as a single string of multiple LEDs (the connection is not via physical cable but via app).
How to activate the Join between multiple Twinkly? From the Devices menu, create a group of devices and assign the Join mode from Type.
Step by Step Guide
To create a JOIN Group go on:
Tap on “Create Group” Button
Give a name to the group by pressing on “Name”
Select “Join Devices” from Type
Tap on Choose Devices and select the Devices You want to group, A rescan button helps in case some device is missing.
Select “Save” on the top right of the Screen
Once the new device group is created, a new device will be visible in the device page, showing also the number of devices included in the group.
