Implementing E220 LoRa Remote Switch to Conserve Wyse Cam3 Battery

The main goal here is to save battery power for a Wyse Cam3 video camera, which uses 180 mA at 5 volts. Since the camera is web-based and only gets a few views a day, we want to stop it from draining power all the time. Right now, a 10,000-mA battery bank only lasts a day, so we need a better way to manage its power. By using a remote switch controlled by an Async Web Server request, we can ensure the camera isn’t wasting battery when it’s not being used.
