A compact Bluetooth-enabled clock and sensor that displays the current time, temperature, and humidity on a crisp e-ink screen. At just 110 × 55 mm with a minimal ABS enclosure, it fits neatly on a desk, shelf, or wall.
The sensor broadcasts temperature and humidity data over Bluetooth Low Energy (BLE) with a range of approximately 10 metres, making it a great addition to home automation setups. It works with ESPHome and Home Assistant as a remote sensor node, or simply as a standalone e-ink clock.

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- ESPHome
- ESPHome is firmware and a configuration system for ESP-based devices used with Home Assistant. It matters because a supported ESPHome configuration can make the sensor easier to connect to a smart home setup without writing low-level code.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
