I'm planning to power a Flukso off a DIN-rail power supply, I haven't got the Flukso yet since I need to get some wiring changed first, but I'd need to know in advance what size the power jack is. The manual says it's centre-positive, I assume it's something like a standard 2.1mm jack?
Yes, it is. I use a distribution cord with several 5.5mm/2.1mm-Powerjacks on a "bigger" power supply to power the FLM, a switch, a data logger... The FLM is delivered with a switched wallwart 12V/1A with 5.5/2.1-standard power jack.

Great, thanks! I have some 2.1mm jacks so I just need to solder up the cables.
(I do the same thing with power distribution, a Delta (efficiency class V) 12V 4A with a splitter cable for CCTV use running to several 12V devices, it's a good thing that that's a near-universal standard for networked devices).
When the electrician installed my DIN rail power supply for the FLM we just cut the supplied power pack's cord in half and used the DC jack end to connect the DIN power supply to the FLM.
It is easy enough to rejoin the DC cable in the future if it is ever required.
Also don't forget to get a breaker switch installed for the DIN power supply (if it doesn't have its own power switch) so that you can easily power cycle the FLM if required.
I have run the FLM for about a year and only had to power cycle it on 2 or 3 occasions, lightning storms seem to get it a bit upset sometimes.

Oh, it includes a power supply? Since a European plug won't be too useful here I hadn't even considered it, but in that case it'll make a perfect sacrificial cord source.

There's a better option than that available (local link, but I'm sure the same thing is available in Europe), I already use these on some other embedded devices that occasionally need to be power cycled (although a few days ago I'm pretty sure I toasted an Alix board by power cycling it by pulling the power connector out, since I had no other way to do it... argh).
The Flukso FLM i received came with an Aussie power pack.
If you are curious here is how i setup my FLM.
The FLM hides behind the metal circuit breaker panel.

So once the breaker surround is put back on the FLM is hidden and the panel looks just as it always did except for the additional FLM breaker and DC power supply.
I was originally worried that the FLM inside a metal distribution box wouldn't get enough wifi signal but it has been flawless. Been running for a year without issue except for a couple of FLM resets required after particularly bad lightning storms. I suspect they were due to power flicker.
The next thing i am going to do is add a Kw/h meter (i have the meter) to the solar circuit but before that i have to make room. So some of the double DIN Clipsal safety switches need to swapped for single DIN safety switches. But this is not urgent as it works so well as it is.
Woops, did the image attachment all wrong, try this instead.
