The IP Switch app has been developed to control the ETH-RLY16 - 16Amp, 8 Channel Relay Module on a local area network. The ETH-RLY16 is only designed to allow one tcp connection from a remote device so using two apps at the same time may conflict with each other if operated at the same time.
The ETH-RLY16 module is a self contained unit which just need power and ethernet connected which allows you to switch 8 single pole double throw relays. It has a built in web interface which you can control the relay states or use tcp packets. Ip Switch App uses tcp packets to control the ETH-RLY16 module.
The app can be setup to operate many ETH-RLY16 boards swiping from left to right to access the next bank of switches. In the setup you swipe to the screen to the left to be able to enter the details in for another ETH-RLY16 board.
