Cannot create group with all my devices

I’ve got three wifi touch switch (one 3-gang and two 2-gang) and installed it, but when I try to create group, 2-gang finds the other 2-gang only and 3-gang only finds itself and cannot find 2-gang devices. Any ideas here to put all together in one group? All the firmwares are updated.

Hi there, currently it’s not allowed to add two-gang and three-gang devices to the same group. What you can do is add all the 2-gang devices to one group and all 3-gang devices to another group.
