Kaze
An all-in-one ambient sensor for Home Assistant, powered by the ESP32-C6.
Overview
Kaze is a compact ambient sensor that measures a wide range of environmental data and exposes it to Home Assistant via ESPHome. It supports Zigbee, Wi-Fi, Bluetooth, and Thread out of the box thanks to the ESP32-C6 module.
Sensors
| Sensor | Measurements |
|---|---|
| BME680 | Temperature, Humidity, Pressure, CO₂ / AQI |
| TSL25911FN | Illuminance (lux), IR |
| WS2812B | RGB status LED |
Connectivity
The ESP32-C6-MINI-1 module provides:
- Wi-Fi
- Bluetooth 5
- Thread / Matter
- Zigbee
These will be utilised to connect to your Home Assistant setup and provide temperature readings.
Software
Firmware is written for ESPHome, making it seamless to integrate with Home Assistant. (Work in progress)

Questions
How big is the Kaze PCB?
It measures 40 × 22.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kaze use?
44 parts, built around the BME680, TSL25911FN, AP2112K-3.3 and ESP32-C6-MINI-1. 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 Kaze KiCad files?
From the Las-Vejas/Kaze repository on GitHub, at the commit this page was made from: the board is pcb/kaze.kicad_pcb and its schematic pcb/kaze.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kaze design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
