I don’t get it well. Do you mean 3 way connection? Such in stairs?

If so, here I use some Sonoff M5 with this method, but it isn’t easy. To do so, I use Home Assistant with Blueprint Shared On/Off State, which sync status from two devices. One Sonoff M5 act as a dumb switch and I have nothing connected directly into it. [I also gave a feedback about this feature to iHost](https://forum.ewelink.cc/t/ewelink-cube-sync-switch-state-for-3-way-setup-on/105341/2). Hope they implement it soon.

Another possibility is using [Sonoff S-Mate](https://www.pontobyte.com/s-mate-2/) connected into one Sonoff M5 to change status.

Sonoff could implement this feature directly into Sonoff M5, converting a switch button to a Scene button, or even implement a eWeLink Remote device into Sonoff M5 gateway to communicate to others.
