We've just added a new project to our Projects area. It uses a Raspberry Pi computer and a DLP-IO8 to monitor up to 5 freezer temperatures, possible basement wetness, and whether there's a power failure. And there's room for adding additional sensors as well.
It has the standard Virtual Wiring web interface, and it also sends and receives text and email messages. See http://www.catalinac...nitoringProject.
