Reduce power consumption on ESP32 #2

Open JshStadler opened 1 year ago

JshStadler commented 1 year ago

The below can be added to the YAML for the ESP to reduce the clock speed of the ESP32 to lower power consumption. It's the lowest speed that supports Wi-Fi, and it works perfectly for me:

esphome:
  platformio_options:
    board_build.f_cpu: 80000000L

I'm not sure how to share this here without logging an "issue".

How much does it reduce the power by? Is it a significant amount? Do you have any benchmarks?

JshStadler commented 1 year ago

@wernerhp Not exactly, but it does make a slight difference. And just for controlling the gate it doesn't need the extra speed. Below are some indications, but I can't confirm how accurate they are.
