Satellite1 Dev Kit is an Home Assistant-compatible DIY voice assistant with ESP32-S3 module, XMOS XU316 audio processor

DIY Voice Assistant in 3D printed enclosure

FutureProofHomes’ Satellite1 Dev Kit is a DIY voice assistant comprised of an ESP32-S3 WiFi and Bluetooth board running ESPHome and an audio “HAT” based on XMOS XU316 audio processor designed for Home Assistant compatibility. It can be used as a smart speaker with a 25W amplifier, a headphone jack, and a built-in 4-microphone array, a music player, and an environmental monitoring system with temperature, humidity, luminosity, and presence sensors. The HAT can also be used with a Raspberry Pi with a 40-pin GPIO header, and two extra 40-pin connectors are reserved for future accessories. Satellite1 Dev Kit specifications: Wireless SoC – Espressif Systems ESP32-S3 CPU – Dual-core 32-bit LX7 processor running at 240 MHz Memory – 512 KB SRAM, 8 MB PSRAM. Storage – 16 MB Flash Wireless – WiFi 4 and Bluetooth 5.x Audio Processor – XMOS XU316 (XU316-1024-QF60V-I32) 16-core 32-bit RISC processor running at 800 MHz with […]

Everything Presence Lite ESP32-based mmWave presence sensor tracks up to three targets simultaneously

Designed by Everything Smart Home, the Everything Presence Lite is a compact, ESP32-based mmWave presence sensor designed to be easily integrated with Home Assistant open-source home automation framework via ESPHome firmware. This sensor features a 24GHz mmWave sensor designed to track up to three targets simultaneously with real-time distance, speed, and positional data (X, Y coordinates). It supports dynamic zone customization, ambient light sensing using a BH1750 sensor, and acts as a Bluetooth proxy to extend Home Assistant’s Bluetooth range. The sensor comes in an injection-molded case, and the company also provides 3D-printable STL files, which you can customize according to your needs. Key applications include human presence detection, smart lighting automation, home security zone monitoring, HVAC efficiency control, fall detection for the elderly, and much more. Everything Presence Lite specifications: Wireless controller – ESP32-WROOM-32E WiFi and Bluetooth module with 4MB Flash mmWave Sensor Built-in Hi-Link HLK-LD2450 24 GHz ISM […]

Home Assistant-compatible 60GHz mmWave radar sensor features a built-in IR blaster (Crowdfunding)

The eMotion Ultra is a Home Assistant-compatible 60GHz mmWave radar presence sensor with a built-in IR blaster with a 15-meter range, a brightness sensor, and a temperature/humidity sensor. It is powered by an Armv8-M KM4 microcontroller with built-in Wi-Fi connectivity and is targeted at simplifying complex smart home setups. The eMotion Ultra 60GHz mmWave radar presence sensor module is reported to be able to “cover up to 40 square meters (430 square feet) using just one device.” It can be configured for up to 4 zones with personalized automations for each zone. The exact Armv8-M KM4 module used isn’t named but is likely based on a Realtek RTL8720CM wireless SoC or other Realtek Ameba microcontroller. Potential applications include security management, lighting automation, home climate control, energy management, and rental property management. We have seen similar presence sensors such as the RoomSense IQ, Seeed Studio’s mmWave fall detection kit, SONOFF SNZB-06P, […]
