In this tutorial we will show how to use Raspberry Pi and relay module as internet controlled switch. You can control up to 17 devices over internet by your phone or remote computer.
EasyIoT server v0.4 is released. New features are:
If you upgrade from previous version clear WEB browser cache or app will not load correctly.
In this tutorial we will show how to build low power NRF24L01 Arduino door/window sensor.
Sensor has low power consumption. 2AA batteries could last at least between 5-10 years. In my test case battery drops for 1% in 43 days. In theory it means 100% in 4300 days, which is about 12 years. Power consumption of this sensor is so low that I'm using wasted batteries from electronic toys and sensor still work. Sensor reports battery voltage back to EasyIoT Server.
