I'm having no luck with my 3-way switches.
I installed a ton of Cooper Aspire Decorator switches about 8 years ago. (RF9501 main switches with RF9517 accessories switches and the RF9540 main dimmer with the RF9542 accessory dimmer.)
While I love everything else about the switches, I've never had any luck getting the accessory and dimmer switches to act together. At one point, I even tried getting the Cooper Aspire controller so that I could use direct association, and that would work great for a short period of time and then just become less reliable.
When I moved from SmartThings to Hubitat, I tried again. I've tried to Eaton switch built-in driver direct association, the joelwetzel Switch Binding method, Basic Rules, and Rule Machine. While those all mostly work, the lag time can be significant. I even got Eaton to send me some replacement switches at one point, but those didn't consistently keep working either.
We're redoing our kitchen, and I'm trying to figure out my options, hopefully having a 3-way switch option that works and (just as importantly from my perspective and my very patient SO's perspective), works as seamlessly and as quickly as a normal 3-way switch.
Since the switches are from 2015, they are all the old Z-Wave vs. Z-Wave Plus. So maybe the Plus versions are just magically better? The fact that the Aspire switch page shows the last update is from 4+ years ago doesn't install confidence, but if I could keep the same look, that would be preferred.
If the Eaton one's still aren't reliable, is there another option that is 100%? I don't know if there's an option that keeps the normal 3-way wiring (power and traveler?) so that they act immediately, but also work with Z-Wave?
Any suggestions or feedback would be appreciated!!
