Hi all. Two separate projects which will need a relay of some sort to
run from a Pi or similar.

Second is something to switch mains safely - a full 13A to run a 3kW
heater. I've drawn a blank: best I can think of is to butcher one of
those wireless mains switch modules, which would at least provide a good
isolation gap :-)

I've used (an earlier model of) these

for that purpose (though I've only been switching a few tens of watts, I
*think* these are 3kW rated)
