There’s something very common to me, and I imagine it’s common for a lot of people. I think it’s called “three-way switch” for when it’s done in normal switches with wires.
Sometimes we want a smart switch button to act synced with another smart switch button. Eg. A switch at the top of the stairs, and another one at the bottom to turn on the stairs light.
I think it’s a mix of the Group and Scene features.
The part that is similar to the Group feature is that I wanted the buttons working together (turn on and turn off), but different from the groups, I want it for specific buttons instead of the whole switch. And I also want it to work when I push the physical button of the switch (like the Scene feature behavior).
Currently, my solution is to configure many scene conditionals to turn on/off based on the state of the other button. But in cases where I want more buttons synced (3 buttons, for example) it starts getting complex, and it’s very hard to maintain.
I hope this can be introduced in ewelink to make this type of configuration easier!
I’ve recently been investigating the feasibility of splitting the app’s scenario '“if” into “trigger” and “state”, assuming that there are 3 switches A, B and C respectively. I configured them for the following scence:
Sence1
When the trigger is:
Switch A turn to ON;
The state is (or):
Switch A OFF;
Switch B OFF;
Switch C OFF;
Then do the action:
Turn on Switch A;
Turn on Switch B;
Turn on Switch C
Sence2
When the trigger is:
Switch A turn to OFF;
The state is (or):
Switch A ON;
Switch B ON;
Switch C ON;
Then do the action:
Turn of Switch A;
Turn of Switch B;
Turn of Switch C
In the union of the above two scenarios, when manually opening or closing A, it will necessarily open or close B and C; however, manually opening and closing BC does not affect A.
For you, do you find the above logics easy to understand? Do they meet your needs?
Thank you for checking this. This is exactly what I’m doing currently as workaround. But the issue is that I need to create a lot of scenes to manage these cases for the whole house, and it’s hard to maintain if I change something.
What I propose would be an easier setting to just set the buttons A, B and C to work in parallel.
As a reference, it seems the app Tuya has this feature with the name “multi-control association”.
