FS20 developments

Looks like the FS20 remote-controlled system from Conrad and ELV has gained a few new units. Here’s a 60-euro 2-channel power-strip, controlled from 868 MHz, hence also from a JeeNode:


Also a 42-euro repeater to get through multiple layers of reinforced concrete.

Great options to avoid having to deal with line voltages. Not ultra-cheap, but still.

The one drawback worth noting with FS20 is that’s it’s not replay-safe. If someone picks up these signals, they can re-send them at a later time, even from outside the house. This means there is essentially no security at all with this approach. But for things like lighting and office equipment, that’s probably not an issue.
