The YOYOPower 4G Relay connects directly to the mobile network, making it easy to control electrical functions remotely. You can choose to use a mobile app, SMS commands, or automation via a connected sensor. The device is flexible and suitable for many different applications – from properties to vehicles.
🔧 Functions and control options
-
Remote power control
Control electrical circuits via SMS, call, or app – no matter where you are. -
Alarms and notifications
Receive instant SMS alerts for power outages, temperature fluctuations, or if a connected sensor is triggered, e.g., due to leakage or burglary. -
Automation
Power control can be scheduled, controlled via thermostat, or activated with a delay. You can also use external sensors like motion detectors to automatically activate the relay. -
Two separate relay outputs
Ability to control two different electrical circuits (5–24V DC or 110–230V AC) independently – manually, automatically, or with sensor control.
📌 Applications
✔ Control or open gates, doors and garage doors
✔ Manage heating systems, fans or pump installations
✔ Monitor and control 12V systems in vehicles, boats or solar power installations
✔ Use with external sensors such as smoke detectors, water sensors or motion alarms
✔ Remote control based on temperature changes – e.g., to start heating or cooling
