This product is a Sonoff G1 switch based on GPRS remote control. Its operation is based on a GSM / GPRS communication module, a relay switching to certain devices (devices, lights, etc.) and a few additional circuits. Also, because the data sent is very low, the device communicates via GPRS, ie 2G. Caution - the product does not work with 3G or 4G networks, even if the data transmission frequencies are the same.

Another important feature of the app is to turn the device off and on at certain times. For example, you can schedule that gardening watering starts at 6 o'clock in the morning and ends at 6:30.

The product can be used in a wide range of fields, from agriculture, in your home or at work.
