I was able to get the switch set up correctly in HA and am now able receive scene events and trigger automations.
I wanted to shut off the internal relay now (because the bulbs I’m controlling are tradfri) but I don’t know how. Using OZW and connecting to the QT UI, I was able to see the setting for SmartBulb mode and I set it to enabled, but it seems like that isn’t the setting that controls the internal relay.
Smart Bulb Mode is the correct first step. It insures that the dimmer will also put out full power.
The next step is to turn turn off local control. That will prevent the dimmer from physically working like a dimmer. Once you do that you can turn the dimmer on via your hub. You should be good to go at this point, but if you want, disable remote control too. That will prevent you from accidentally turning the dimmer off via the hub.
Someone else has posted what the 3 settings do, but disable local control only is Protection by Sequence and disable local AND remote control (no scenes, etc.) is “No operation possible”.
Awesome, thanks for this additional info. While doing it through the config button sequence worked - It’s helpful to be able to do it through the UI as well.
