Unifi kit from Scottish Power for monitoring power and switching a device.
It is at least 10 years old and I don't know if the back end servers are still running or whether this can be used in the original way but it might be interesting for someone who wants a project to try to repurpose it. Searching on "Unifi Scottish Power" gives a few hits including one from someone who tried to reverse engineer it.
At the very least you get a couple of 9V power supplies!
