Hi guglulenun,

I am glad you have got it working.

The problem was with the syntactic construction of your XOUT line.

Once you have defined the House and Unit codes, the line should be in the format:

XOUT SIG_OUT,ZEROX,[HOUSE\UNIT,HOUSE\unitOn]

Since you have included modedefs.com, you can also use all the pre-defined X10 commands directly .

Also, you can use byte variables for House and Unit, as they only go up to 16.

Regards,

Anand.
