Step 1: Download the GMail Remote Controller from
http://www.gianniamato.it/grc/Step 2: Extract the file. There is no installation. It's just a simple, stand-alone program
Step 3: Setup a GMail account. (You may want a special account just for X10 but that's optional)
Step 4: Create a batch file using notepad to execute the desired commands. Mine is called on.bat and looks like this:
d:\Users\David\Desktop\ahcmdmods\ahcmd.exe "sendplc" "b10 on"
d:\Users\David\Desktop\ahcmdmods\ahcmd.exe "sendplc" "b12 on"
d:\Users\David\Desktop\ahcmdmods\ahcmd.exe "sendplc" "b13 on"
* Be sure to save this in your c:\ root directory! (or E or F or whatever drive letter you use)
Step 5: Open the GRC.exe file
Step 6: Click 'Settings'
Step 7: Change the Subject Tag Left/Right to something easy (I use a hyphen for both)
Step 8: Click Login, fill out the blanks and click the 'Sign in' button
Step 9: Text an email to your GMail account. The command goes in your subject line. Do not put text in the body. (Ex: -c:\on-)
Step 10: Wait about 1-2 minutes and the commands will execute
Step 11: Delete the email from GMail and close GRC.exe
Step 12: Repeat steps 5-11 to reset the process.
Note: Since I am unable to make a text template insert in the subject field, I save a copy of the text message in my phone and forward it to GMail when I want it to run. This causes the subject to insert 'FW: ' so I make my Subject Tag Left 'FW: -'
Also note that d:\Users\David\Desktop\ahcmdmods\ahcmd.exe is just telling the bat file where ahcmd.exe is.
Good luck!
