White Switches: 3-way dimming

[harryh]

I have two white smart switches wired up so one is the master switch which controls the (dumb) load. The other has no load attached.

I’m totally good with just turning the load on & off. I just set up two automations in home assistant to keep the two switches in sync. Easy peasy.

But I’ve got a dimmable dumb bulb. Is there a good way to make both switches dimmers and keep them in sync using home assistant? It doesn’t seem so?

I guess that these switches can be paired togther and that would do the trick for me, but Home Assistant doesn’t make that easy for me yet. Maybe I just wait a bit for HA to get Thread pairing working?

HA Blueprint: Matter Switch Tap Sequences

[Open your Home Assistant instance and show the blueprint import dialog with a specific blueprint pre-filled.] I’ve updated the blueprint to add light binding. The UI is also a bit more polished as well. To update to the newest version you can click on the blue link above to reimport it. It sounds like matter binding won’t be available in HA for quite some time, so hopefully this can work as a bridge for some users for the time being. You can also use it to bind the switch to other smart light…

This is probably your best bet right now. Matter bindings are still not a thing on any platform.

I spent a couple hours today confused how to proceed with a 4-way setup (all white 2-1 smart switches) meant to be controlling a dumb load.

I can follow the wiring diagram provided, but was lost beyond that.

What do I need to do to make each switch independently switch the load, as a traditional 4-way circuit would allow?

Most of the other discussion I’ve seen is in regards to virtual multi-way switches spanning multiple non-connected circuits which will rely on a forthcoming hub feature called matter binding.
I think my case is simpler, where I’m just looking to understand what modes my switches need to be in if wired according to the Inovelli diagram, or if there are wiring changes I should make to easily have 3 smart switches (with neutral wires), switch a single load.

Thanks so much for any help.

Hi Nick, unfortunately, no - you are in exactly that situation you describe. Your switches happen to be powered by the same circuit, but that doesn’t get you anything. There is no way to WIRE together multiple smart switches. The intent is that they will be linked by binding (when that’s available). For a wired connection, you need one smart switch & one or more Aux switches.
(This is the same for red & blue series, except there the bindings/associations are possible)

Since matter binding is not a feature presently supported, you should use automations to control the load switch. The multi-tap capabilities of the switches vary by hub.
