YOYOPower 4G Relay – Smooth remote control with alarm functions
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.
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.
✔ 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
