Kangaroo’s new sensor (we’ve previously reviewed its motion-only sensor) makes for an enticing choice given its no-tools, no-hub setup, not to mention its $30 price tag.

Outdoor sensors are even more limiting than outdoor lights which is why we were so excited during CES 2019 to see the Hue Outdoor Sensor. This is the first — and only — HomeKit-enabled outdoor ...
