Lights with 2 way or 3 way or even 4 way - Master/Slave Relationship

[u15jtau]

What’s the most efficient way to setup lights that have a master slave relationship eg I have 1 switch that controls the light (wired to the light) but I have multiple other “slave” switches that I want to control the same light via automation (not wired to the light). Each time I’ve set up a flow in node red it creates a loop. The loop eventually ends but I’d prefer to have something that doesn’t create a loop. Here’s what I currently have for 3 light switches.

If the switch can be detached from the lamp, then it can be used to run a script.

Other than that you will have to look into a trigger id.

I think this is the best I can do with no loops.
Hopefully this helps someone given the amount of help I’ve received from this community reading old threads

In short the solution is

1. State change - list all entities where there can be a change as this is an “or” node
2. Get entities - I used a group helper as this is an “and” node and you’d need either 3 nodes or a group and given I’ll have 4 and 5 way switches then this is probably the easiest. The entities need to be the same as in 1 above. You can’t use groups in 1 above as if 1 item is on in the group then the group is on so turning off doesn’t work.
3. Function - Part a: Put all the entities through a function to compare their state to the state change and if the state is the same then exclude them from the output
4. Function - Part b: Pass the turn_on/turn_off. This makes everything a variable in the action node. This means you only need to maintain 1 and 2 above.
5. Action - empty as it gets everything from the function node
