Just came across the MK Echo wireless switch system. Sounds quite
interesting.

And for prices, there are 58 results on amazon.co.uk.

The biggest downside seems to be their high cost. Are there any other
manufacturers of similar products. (It sounds as if the technology is
being made common to permit interworking.) Anyone got experience of using
them?

To be honest, for now, the ordinary plug-in devices that cost a tiny
fraction of those prices does everything I really need. So this is by way
of interest rather than serious intent.

Interesting that the transmitter works without batteries by
"harvesting energy". I wouldn't have expected it to work.
