Our take
YoLink uses LoRa instead of WiFi, giving up to quarter-mile open-air range and rock-solid coverage across basements, garages, and outbuildings. The Sensor 4 adds a loud onboard siren, and Control-D2D lets sensors trigger valves or sirens even if internet is down. The required hub and somewhat dated app are the main trade-offs.
What we like
- Exceptional LoRa range that reaches far-flung spots WiFi can't
- Loud 105dB built-in siren on each sensor
- Offline device-to-device triggers can shut a valve without internet
- Works with Alexa, IFTTT, and Home Assistant; one hub scales to hundreds of devices
What to keep in mind
- Requires the YoLink hub, which is a single point of failure
- App interface feels dated and has a learning curve
- Cloud-dependent for remote notifications and reliant on YoLink's servers
