Networks, Relays and remote switching

Make your own cheap charlie Z-Wave type control, minus the RF stuff (so really nothing to do with Z-Wave, more of a remote controlled Home Automation relay), using an Arduino in conjunction with an Ethernet Shield and a Relay shield, with this Instructables guide, Ethernet Switching – with Arduino.

  • HC-06 – BT Slave only
  • HM-10 – BLE – The HM-10 can operate on a lower voltage at the expense of real estate.
  • HM-11 – BLE – The HM-11 has significantly less I/O exposed off the interposer PCB, including GPIO and USB [source]. See also the XBee Bluetooth blog

Which one is the right one?
