For one of my projects, I am using a SG90 servo connected to a Wemos D1 Mini and controlling the servo via Home Assistant using an input_number helper and automation there.
For another project, I am wondering if anyone here did the same, but without Home Assistant. So using the ESPHome webserver to serve a page with buttons or a slider to control the SG90 servo, without the need of Home Assistant, so stand alone on the ESP?
