I just purchased TL135, my first smart lights.  I was planning to flash them when Tapo doorbell was rung (button pushed), but discovered that was not an available action, which was unexpected; I assumed that was a basic function/operation for smart lights.  I found info on doing it with 3rd party apps/hubs/sites.  Is there a technical reason 'blinking slow/med/fast for x seconds" is not a standard/available action?  It looks like I could turn it on for a second, delay for a second, turn on again for second, and do that 30 times, but that will be tedious.

Speaking of tedious, is there a way to enter the RGB color directly rather than use that color selector?  I chase that little circle around for 60s trying to get on a specific color.  In some cases you cannot even see the value while you are doing it!
