valid carbon
I reflashed an Emporia smart plug (Uses an ESP8266) with ESPHome and have been working on configuring it to mimic the original functionality. The basic config did not include control for the blue LED, it just uses the red one as the status LED. I figured out that the blue LED is controlled by GPIO3, which is also the RX pin for the UART. I'm able to turn the GPIO on and off, but the blue LED is very dim when on, like it's being powered through a pull-up resistor instead of being driven by an output.
I tried adding
baud_rate: 0```
as an attempt to disable the UART, but it didn't change the LED behavior. I also tried to re-assign the UART to `UART1` with similar results.
Is there something else I need to do to get GPIO3 to be able to be a nice low impedance output?
