Hot Body Alert is a plugin that will send an email to an address you specify whenever motion is detected by a sensor. You can only define 1 sensor as the trigger though and the email subject line just says HotBody Alert, which makes it virtually useless in the real world. Additionally the body of the message has this: "Click the link below to connect your iWatchMobile PRO to the ActiveHome Pro system.", with a 3G link and a WiFi Link. Lotta good that will due you if you don't have that plugin as well and a camera setup in the area of that particular motion sensor!
