The ESK-1 is designed in collaboration with the Open Home Foundation. A portion of the profits from each ESK-1 sold goes directly to the OHF team to support their work on Home Assistant, ESPHome, Music Assistant, and other open-source smart home projects.
ESP32-C6 Based: Built on the ESP32-C6-mini module with Wi-Fi, Zigbee, and Thread radios for versatile smart home connectivity.
Zigbee & Thread Support: Dual antennas for Zigbee and Thread protocols. Supports Matter over Thread for future-proof smart home integration.
USB-C Power: USB-C port for easy power and programming.
Expansion Ports: Two 13-pin FPC cable ports allow you to connect and power virtually any sensor or accessory.
Onboard Controls: Boot and Reset buttons for easy flashing and debugging.
Battery Powered: Includes battery connector with MAX17048 fuel gauge for accurate voltage and percentage monitoring.
Deep Sleep Support: Configurable deep sleep duration for extended battery life. Wakes periodically to report sensor values and returns to sleep.
RGB Status LED: Onboard fully addressable WS2812 LED indicates battery status:
- Red: Battery below 40%
- Yellow: Battery between 40-79%
- Green: Battery 80% or above
Prevent Sleep Toggle: Easily disable deep sleep via Home Assistant for OTA updates or continuous monitoring.
Accessory Power Control: GPIO-controlled power rail for connected accessories, automatically disabled during deep sleep to conserve battery.
