README
README.mdHome-Assistant-Control-pad
This is a programmable Home Assistant Control Pad. It can control 4 Home assistant devices at a time, and has 4 togglable screens/zones (in total 16 devices). It uses buttons and rotary encoders to enable and control other HASS devices. It also has an OLED Display (1.33") to display the status of the devices. It is battery powered, it contains a 1800mAh Li-Po. The device uses an ESP32-S2 and ESPHome.
Why I made it?
I made this project as I wanted an easy and fast way to control the "smart" devices I have made. I'm making quite a few ESPHome devices and wanted something to control most of them easily.
Features
- Controls Home Assistant entities (lights, switches, etc.)
- Over-the-air (OTA) updates

Questions
How big is the Home Assistant Control pad PCB?
It measures 85 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Home Assistant Control pad use?
111 parts, built around the ESP32-S2-MINI-2-N4R2, TPS631010YBGR, B3F-4055 and PEC11R-4220F-S0024. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Home Assistant Control pad KiCad files?
From the Pegoku/Home-Assistant-Control-pad repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Home Assistant Control pad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
