Overview
- Full DIY package: enclosure, PCB, and firmware to build inki without a programmer.
- Quick‑start UF2s: prebuilt images to preview setup and the web interface on a bare Pico W; same firmware runs on fully assembled devices and supports OTA via the web UI.
What’s Included
- Hardware: 3D‑printed enclosure files and custom PCB (RTC, power management, ePaper).
- Firmware: C code for RTC wakeup, Wi‑Fi, web UI, HTTP client, XML‑RPC for Homematic, and ePaper rendering; build/flash/UF2 scripts.
- Prebuilt UF2s: single‑file images (bootloader + firmware + default config; valid_flag pre‑set).
Highlights Since v0.12.0
-
Improved support for different epaper support for each use case
-
weathermap use case: maps are fetched and stored - work in progress
-
Assets
Prebuilt images for USB writing:- inki_seatsurfing.uf2
- inki_historian.uf2
- inki_homematic.uf2
- Source code archives (zip, tar.gz)
Quick Start
- Hold BOOTSEL while plugging in Pico W → RPI‑RP2 drive appears.
- Copy one UF2 (inki_seatsurfing, inki_historian, or inki_homematic) → board reboots automatically.
- Connect to AP “inki‑setup” (password “12345678”) → open http://192.168.4.1. Configuration for respective application can be set via corresponding web interface.
Hardware For Full Functionality
- RTC: DS3231 (timekeeping and power management).
- ePaper: Waveshare 7.5" V2 or 4.2" V2 (select your panel in the web UI).
- The UF2s run on a bare Pico W to preview the web interface; ePaper rendering and time‑based features enable when hardware is present.
