I came across this post searching for the same answer. I have several locations that require non-neutral switches, however the connected lights are regular (not smart) and non-dimmable lights. While this thread got me close, it still took some trial and error to figure out completely.
After updating my switch to the 1.48 firmware, I tried using Smart Bulb Mode. This did disable dimming, however it also disabled local control of the relay. In other words, the lights were always on and could no longer be turned off using the switch on the wall.
Almost what I wanted, however setting parameters 1-2 to 0 just make the lights dim instantly. I don’t want them to dim at all.
So here’s what I’m currently testing and so far seems to be working
Parameters 1-2 set to
100 – This controls the dimming speed, that is how fast or slow the light dims. I don’t want the light to dim at all. So setting this to the highest number possible, slows the dimming effect as much as possible.
Parameters 3-4 set to
0 – This controls the ramp rate, that is how fast or slow the light turns on/off. As noted in the manual, 0 = Instant On / Off
I also set parameters 9-10 to
99 – This sets the default brightness, this ensures that the light is always turned on with full brightness. (just in case it dimmed somehow)
I feel fairly confident that setting parameters 1-2 to
100 is effectively disabling the dimming. Even if it’s still happening very slowly, the rate is so slow, it will prevent any significant amount of dimming by accident.
I’ve tested holding down on the switch for various amounts of time, up to ~6 seconds. Sometimes I notice a slight flicker after a few seconds, but the light (and the LED status bar) remains a full brightness. If I hold the down on the switch longer than 4 seconds, the light will just shutoff instantly when released.
