My Shelly arrived (thanks for the recommendations Fedi!) and I've got to say, it seems pretty good..

The biggest annoyance is that it's clearly designed for European form factor wallboxes, which don't have ring mains. So it's a little difficult to cram in.

The device itself does get warm...

@crablab Wait, Europeans don't have ring mains ?
I just assumed _everyone_ did.

Gosh.

@steely_glint Ring “main” (more correctly called ring final) circuits are a weird UK thing brought about by copper shortages in the early post-war (WW2) years plus a conviction on the part of planners during the war that post-war house heating would be mostly use electric powered by nuclear. Almost nobody else bothers with them.

AIUI, they're becoming less common now in new build even in Britain which is, IMHO, a good thing as, if they were ever used at the power levels they were originally designed for, would be intrinsically fail dangerous.

If you're actually using the power delivery capabilities provided by the two paths to a group of sockets but there's a break in one side of the ring the devices will appear to continue to work but the half ring will be overloaded. Luckily, in real life it's very rare to draw enough power for that to actually matter.

A ‘ring split’ test button might’ve been a useful part of the design/spec for a 2 gang 13A outlet.

Been thinking that EuroMod 13A outlets would be a good complement to Shelly 1 units (as replacement for a 2-gang outlet). Need to check regs…
