I have a design I have been using with an LCD that I have the backlight connected to a SX1509 IO pin to be PWM’d for brightness. This was working great with esphome 1.16.2, then today I updated to the latest ESPHOME 2021.8.1, and the backlight broke. It is either dim or it tries to go bright then flashes which may be due to too much current. Anyway the weird thing is in Home Assistant I no longer have the brightness bar for the backlight.
I can’t see any breaking changes in the SX1509, and I don’t know why it would drop the brightness information from a monochromatic light.
Does anyone know why the brightness attribute may have disappeared?
