One sensor for presence detection and air quality monitoring?
I tested the Ultimate Sensor & Ultimate Sensor Mini to see if they truly live up to their name.

In this video, I take an in-depth look at the Ultimate Sensor and Ultimate Sensor Mini, two new Home Assistant–focused sensors developed by Dwain (known from Dwain’s Dashboard). These sensors combine mmWave presence detection with advanced air quality monitoring, all running 100% locally.
