I have a large room with three different light switches controlling lights throughout. All of the switches are zwave dimmers. I want to be able to turn on/off and dim all of the lights from any one of the switches. I’ve tried groups and some logic in node red with no success pressing the switch. I can obviously control the group from the hass gui, but that’s not what I’m after. Please help.
I can imagine at least two solutions.
If you see the buttons on dimmer as separate entity, just attach automation on it.
If not, try attach automation on state change, automation which will ‘synchronize’ other dimmers.
Look into group associations if they are available for the type of switch/dimmer, so it even works when HA is down.
Have you used Home Assistant Events.
I did this for my Philips Hue - then pressed each button.
I then created an automation for each button that controlled several lights.
This is exactly the kind of thing I was looking for. I guess I thought it would be done in HA not zwave. Thank you!
