tldr: how do I bind (zigbee) the occupancy of switches so that they all share that state - similarly to how you can set the on/off or brightness state?
I received my Blue series mmWave dimmmers and am so far very pleased with them. I have a configuration issue I’m trying to resolve. My stair well is a 4-way configuration and I wanted presence detection at each location (garage door, entryway, landing) so I installed 3x mmWave dimmers.
The wiring is such that they don’t use traveler wires and so therefore don’t “know” each other’s state (on/off) like the would in the ‘Aux’ configuration. This means that the dimmer closest to the load is what actually controls it. They other switches just forward the line power along.
This means that the on/off and brightness states must be synced via binding. I’ve done this in Z2M without issue. That all works great… whenever motion is detected at any switch the lights go on. However, if you are in an area outside of the ‘view’ of the last switch in line… the lights will turn off in a few moments.
My assumption is that this is resolved by synching the “occupancy” state between switches via binding. I’ve tried binding them on endpoint 1 and selected msOccupancySensing but that doesn’t seem to have an effect. I’ve tried binding the switches on endpoint 2, 3, and 4 but there is no option for occupancy.
Is this something I have to do in HA? I hope not. Binding isn’t an ideal solution to begin with but acceptable. Automating in HA would be much less flexible.
