+# Using the PicoCalc with Home Assistant
+
+This example demonstrates how to use your PicoCalc with Home Assistant via the [ESPHome Project (https://esphome.io/)](https://esphome.io/)
+
+![Home Assistant Example](../../Pictures/homeassistant_example.jpg)
+
+## Prerequisites
+
+* A working Home Assistant installation with ESPHome installed
+* PicoCalc with a Pi Pico 2040 W or Pi Pico 2 2350
+
+## Setup
+The easiest way to get started is to use the ESPHome dashboard and make a new device,
+get your Pi Pico W flashed and registered/connected with ESPHome.
+
+You can then copy the configuration bit you want from picocalc.yaml into your
+new devices configuration and you can now reflash wirelessly.
+
+## Current Status
+
+What Works:
+* WiFi
+* SPI with the Display
+* LVGL (UI) with widgets and updates
+* OTA Updates
+* Using a text_sensor to live-update my garage light status (example)
+
+## TODO (in no particular order):
+
+- [ ] Enable I2C
+- [ ] Enable the keyboard
+- [ ] Enable Backlight Adjustment
+- [ ] Enable Backlight Keyboard
+- [ ] Enable the SD card
+- [ ] Enable the GPIO pins
+- [ ] Enable Audio
+- [ ] Enable... whatever else.
