I have about 30 Kasa Smart Dimmers, HS220, original WIFi models I assume.  I just added a new black HS220 and see that it is now Bluetooth for setup and also has several additional items in the app configuration for this dimmer.  This new HS220 replaced a white Wifi HS220. 

I set it up and have calibrated several times but when the connected light turns on or off, the dimming occurs in very abrupt steps.  Not the smooth ramp up or down I'm used to w/my WiFi HS220s.  

Am I missing some configuration step?

Thanks,

Steve
