Feature request: One node-red switch to multiple in HA (one switch to rule them all) about hass-node-red HOT 3 CLOSED

At the moment I don't see a feasible way to accomplished this. The switches are identified in HA by the node id from NR. So each switch in HA is a one to one reference to a node in NR.

You could expose each event node to HA and then make an input boolean in HA that when changed it sets all the event node switches to the same state as itself with a single call service. That's not much different from what you're doing now though.

@xppx99 Just happened to be browsing and saw this -- I use a group in my Home Assistant config to give me single control of multiple NodeRED "Switches".

Hello guys! So actually there is a way to do what I was asking about with the functionality already provided by this integration.

The way is this: Exposing one of the switchs to act as "master switch", then replacing any "events: state" nodes by the improved "trigger: state" nodes, and then add a condition so that the msg are only propagated if the previously creater "master switch" is ON.

This way, everytime I deactivate the "master switch", every other trigger is also blocked, by the condition added.
This as been working great!
