Coming from Hubitat to HA and am tearing my hair out how to mimic their switch bindings feature. I have 2 dimmers (They are Z-wave but that doesn’t really matter) - and I want to make them act like a 3 way switch pair. In Hubitat you just used the switch bindings feature and away you go. Dimming one or the other dims the opposite one - the load can be connected to either one. No need traveller wires or anything. I have a few non-dimming switches I’ve setup with Automations to turn one off when the other is off etc, but I have no idea how to easily do this with a dimmer… I suppose I could create an automation that every time there was a state change on one, it would copy the level to the other? But that seems like a heck of a lot of work for something that was so simple on the Hubitat…
Both zwave and zigbee have association/binding within their protocols.
There are blueprints for home assistant that do this function.
I’m sure Perplexity.ai can give you several answers. Claude is good at writing HA templates if you don’t want to use a blueprint.
