Made a new application for the Red Bokito. The Red Bokito is checking email for every 2 minutes. By sending an email it is possible to switch ON/OFF/TOGGLE the four relays of the board. And after succesfully switching receive a confirmation email. Used 2 socket of the WIZ810MJ, socket 0 is for receiving the commands with POP (PostOffice Protocol), and on socket 1 the confirmation email is done by SMTP. Sample code can be found here: Emailswitcher
The complete stream of commands can be followed by PRINT-statements.
