What the differences mean

Outdoor use

The Ring Outdoor Contact Sensor is rated IP66, built for gates, sheds and garage doors exposed to rain and cold. The Ecobee SmartSensor for Doors & Windows carries no weather rating, so it belongs on interior doors and windows.

What it needs

The Ring Outdoor Contact Sensor talks Z-Wave and needs a Ring Alarm base station or another Z-Wave hub. The Ecobee SmartSensor for Doors & Windows talks to an Ecobee thermostat and does nothing without one. Neither works on its own.

Platforms

Through the thermostat, the Ecobee SmartSensor for Doors & Windows reaches Apple Home, Alexa and Google Home. The Ring Outdoor Contact Sensor works with Alexa and Home Assistant, but not Apple Home or Google Home.

Battery

The Ring Outdoor Contact Sensor is rated for 5 years on two AA cells you can buy anywhere; the Ecobee SmartSensor for Doors & Windows for 3 years on a CR2477 coin cell.

Extra sensing

The Ecobee SmartSensor for Doors & Windows adds occupancy sensing, which the Ecobee system uses to tell whether someone is home. The Ring Outdoor Contact Sensor adds tamper alerts instead.

Size and warranty

At 60 x 29 mm and 38 g the Ecobee is small and discreet, and Ecobee covers it for 3 years. The Ring is a bulky 136 g unit built for gates, covered for 1 year.

What owners say

Owners of both sensors agree on fast, reliable open and close notifications and an easy pairing with the system each one belongs to. Ecobee SmartSensor for Doors & Windows owners single out the thermostat pausing the heat or air conditioning when a door is left open, and small, discreet sensors, while their main complaint is that most security features sit behind an Ecobee Smart Security subscription, along with limited voice assistant control. Ring Outdoor Contact Sensor owners talk about monitoring gates and garage doors, reliable operation in deep cold, long Z-Wave range and a forgiving gap between sensor and magnet, and they complain about a sensor and magnet that slide off their brackets with a bump, a finicky tamper switch and a bulky housing.
