Re: Mains but no phone line-still a way to communicate?

Available are two way systems that use the mains as both supply and signal transmission, and I believe I saw one as a baby alarm.
The cabling must be on the same phase though. So if there is 3 phase in the property, the houses may be on different phases.
This shows one type, but others are available. Maybe not cheap though, but can be removed when moving.
