Adjusting Wi-Fi power save

The ESP chips produce a significant amount of energy (heat) constantly using Wi-Fi. This guide explains how to adjust the Wi-Fi power save mode to high to combat this.

This will negatively affect your Wi-Fi performance!

While some options can reduce the power usage of the ESP, they generally also decrease the reliability of the Wi-Fi connection, with frequent disconnections from the router in the highest power saving mode.

1. Open the ESPHome Device Builder.

Open your Home Assistant instance and show the dashboard of an app.
