Why Won't My YoLink Sensor Connect to the Hub?

Smart Sensors • YoLink Sensor

Your YoLink sensor is not connecting to your YoLink Hub. In the YoLink app the sensor shows as offline, unreachable, or simply does not appear. YoLink sensors use LoRa sub-GHz wireless (915MHz in North America) — not WiFi, Zigbee, or Z-Wave. They communicate exclusively with the YoLink Hub, which connects to your router via ethernet. If the hub loses its internet connection, every sensor attached to it will show offline regardless of battery status. Most connection failures trace back to the hub being offline, a depleted battery, or a lost pairing link.

Why Won't My YoLink Hub Connect to Sensors?

Smart Hubs • YoLink Hub

Your YoLink hub is not discovering or connecting to sensors during setup. The hub communicates with sensors over LoRa (long-range radio), not WiFi or Bluetooth. The hub must be online (solid blue LED on the front) and the sensor must be in pairing mode. This guide covers checking hub status, putting sensors in pairing mode, and range considerations.

How Do I Set Up the YoLink Outdoor Motion Sensor?

Smart Sensors • YoLink Motion Sensor

You are setting up the YoLink outdoor motion sensor. The sensor is weather-resistant and communicates with the YoLink hub over LoRa. Mount it at 6-7 feet height pointing toward the area you want to monitor. Detection range is up to 30 feet. This guide covers mounting, pairing to the hub, adjusting sensitivity, and setting up alert notifications.

Why Won't My YoLink Water Sensor Send Alerts?

Smart Sensors • YoLink Water Sensor

Your YoLink water leak sensor is not sending alerts when water is detected. The sensor detects water through two gold-plated contacts on the bottom that must be in contact with a flat surface. If the contacts are dirty, raised off the floor, or the sensor is offline, alerts won't trigger. This guide covers checking pairing status, cleaning contacts, and testing.

How Far Does the YoLink Hub Signal Reach?

Smart Hubs • YoLink Hub

You want to understand the YoLink hub's signal range. YoLink uses LoRa (Long Range) radio technology instead of WiFi, Zigbee, or Bluetooth. LoRa provides significantly longer range — up to 1,000 feet outdoors and 200+ feet indoors through walls. Actual range depends on building materials, interference, and sensor placement. This guide covers range expectations and extending coverage.

Why Is My YoLink Outdoor Temperature Sensor Reading Inaccurate in Direct Sunlight

Smart Sensors • YoLink Outdoor Temperature Sensor

Your YoLink outdoor temperature sensor shows readings much higher than the actual air temperature during sunny days. The sensor may read 100°F when the actual temperature is only 80°F. Readings are accurate at night or on cloudy days but spike unrealistically when the sun hits the sensor.

Why Does My YoLink Door Sensor Battery Die So Fast?

Smart Sensors • YoLink Door Sensor

Your YoLink door sensor battery is dying much faster than expected. YoLink door sensors use either CR2032 coin cells or AAA batteries depending on the model. Battery life depends on how frequently the door opens and closes, and the reporting interval setting. Sensors on frequently used doors drain faster. This guide covers checking battery type, adjusting settings, and replacement.

How Do I Set Up the YoLink Valve Controller?

Smart Sensors • YoLink Valve Controller

You are setting up the YoLink water valve controller to automate a manual ball valve. The controller clamps onto existing ball valve handles (fits 3/4" to 1-1/2" sizes) and turns them open or closed via a motor. It communicates with the YoLink hub over LoRa. This guide covers checking valve compatibility, installing the motor clamp, and pairing to the hub.
