easySwitchBox: Remote LoRa® wall switch powered by coin cell battery and Arduino IDE

easySwitchBox does one simple thing - it sends an on/off signal to any relay, actuator or other item. It can be used to trigger any event wirelessly and over long distances (even up to several kilometers using LoRa®). Programming is easy using the Arduino IDE, and communication is protected by a certified chip. easySwitchBox not only makes your projects more efficient, but also looks more professional.
