@Henk, did you change the device number of the code to match the SND device that was created?
(luup.call_action( "urn:upnp-ap15e-com:serviceId:SND1", "SendMail", { message = 'Message from Vera' }, 11 )
*(replace 11 with the SND device ID.)
@Ap15e, works great.
"Message from Vera" appears in the emails subject (which is easily changed for the event)
Each of the 12 test emails generated had a single random letter or number in the body of the email when they were received.
w,u,5,a,d,c,u,m,o,f,0,5
