This repository contains my devices based on ESPHome. Each yaml in this repository represents one of my devices and can be programed following the instructions bellow.
The devices folder contains the instructions for each device (firmware, schematics, 3D boxes, etc).
Programming
To program/update these devices you need to:
- create a
secrets.yamlfile. You can usesecrets_template.yamlas base - start the esphome dashboard with this git repository as config folder.
- Connect to the dashboard
- First time you program your device you will need to program via a serial port. You might use a CP2104

Questions
How big is the Pot watering controller v1 PCB?
It measures 64.6 × 87.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pot watering controller v1 use?
43 parts, built around the ESP32-WROOM-32, AMS1117-3.3, LIS3DH and MCZ33996EK. 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 Pot watering controller v1 KiCad files?
From the angelnu/esphome repository on GitHub, at the commit this page was made from: the board is devices/pcb-pot-watering/controller/KiCad/pot_watering_controller_v1.kicad_pcb and its schematic devices/pcb-led_lights/kicad/pcb-led-lights/pcb-led-lights.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pot watering controller v1 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
