Quick Start - tjhorner/wifi-desk-controller GitHub Wiki
This page is intended to guide you to the simplest way of setting up your desk controller based on your situation. If you want a more detailed guide that goes over the pros and cons of each way, see Getting Started.
Do you already have ESPHome (cli/dashboard) set up?
Yes!
Alternatively, you can flash the stock firmware and adopt the device through the ESPHome Dashboard (it should show up automatically once connected to WiFi).
