Not sure if anyone has played with the original EP1 sensor, but cost was an issue for many. They just announced a 'Lite' version of this sensor, which is still a pretty impressive package, for a much lower price. I'm sure the backlog will be significant since the original sensor was almost always out of stock, but check out the specs.
There are a few of these mmWave sensors on the market now, but the open design, extremely affordable package, and not having to order from AliExpress makes this a winner IMO. S/H was $15 for 2 of these to US.
Features:
- Advanced mmWave Sensing: The included LD2450 mmWave sensor boasts an impressive range of 5-6 meters, making it perfect for small to medium sized spaces.
- Multi-target Tracking: Track up to 3 different targets simultaneously with near real-time information about distance, approach angle, speed and X & Y co-ordinates!
- Dynamic Zones & Analytics: Customize detection zones from Home Assistant, allowing you to detect where a target is located.
- Ambient Light Sensing: Equipped with a light sensor to gauge room darkness, making your automation even more responsive to environmental changes.
- Bluetooth Proxy for Home Assistant: Extend Home Assistant's Bluetooth range with ESPHome's Bluetooth Proxies!
- Powered by ESP32 & ESPHome: Easy integration with Home Assistant.
- Versatile Development Board: Compatible with 5+ different mmWave sensors, this is a developer’s playground for sensor testing.
- Case included: Encased in a 3D printed white shell with a right-angle braided USB-C cable (included). 3D Printing files will be made available soon.
