Arduino to remotely reset a crashed miner

I have set up an Arduino (Arduino Uno + Ethernet Shield + Relay Shield) to remotely reset crashed miners. At a crashed state, no software can be executed and no remote connection (using TeamViewer, Remote Desktop) is stablished.

The relays control the "Reset SW" on the motherboard to allow the hard reset of any of the machines by setting the appropriate relay to "high". The arduino can be accessed from the network via .html (using a internet browser) to change the state of the relays. This setup is for 4 relays but it can also be implemented with more relays (Enclosure won't fit though)

The issue is discussed here: http://forum.arduino.cc/index.php?topic=214241.0. The code was taken from: https://www.proto-pic.co.uk/content/arduino/Ether_Relay.zip

    how do you select the rig to reboot when there is more than 1 rig connected? or you have it all predetermined in your program?
    I need to make this for 20+ rigs and I am confused a bit.

    Why would you even let the mining rig crash in the first place? That's some bad instability.

    Why not just use a Wi-Fi smart plug?

    I have been away for a while, only recently did I see anyone replayed.

    @racheta The code can be edited to fit the purpose. Also, there might be newer projects with better coding.

    @ShayanTheThief Sometimes when you have more than just a few rigs at a remote location this is very useful to do. Depending on the issue (raisers, MB, etc) it may happen every month or every week.

    @Jroc4653 Those seem great, they were a bit costly back then. Now they seem to be made cheap. Things to consider: The quality, getting one for each rig (with a double-PSU cable per additional PSU) and make sure they can handle your single PSU wattage and voltage (I use 220v)

    @MRG I wouldn't call that a complete RIG
