I think I meant kW. My understanding of the line graphs is that you can see how much power was being consumed at a point in time and underneath the x axis it shows how much power was consumed in total.

I did that a while ago as my PV was occasionally tripping out and the advice was that a high mains voltage may be causing it. DNO did a week long survey which showed it was high but within limits, the limit being 253V. They told me that if they wound it down for me there would be problems with low voltage at the other end of the line. In a nutshell, I think I’m stuck with the high voltage.

@PeterW This is a ‘normal’ days charging: Below is Saturday, I woke up early to find that the Shelly had tripped off for ‘over power protection’ every time I turned it back on (via the app) the kW’s increased rapidly from 3.1 to 3.5 at which point it tripped off. The same happened a bit later in the day until it finally stayed on to complete the charge: it’s back on now, supply voltage is 248.6V and the Shelly is registering 3.4kWh

@joth I think I'm getting it. Just for clarity, the Shelly replaced the timer in a fused, timed, spur. The relay in the Sunamp controller which is downstream of the Shelly is doing the 'heavy lifting' as I see (and hear) it. Does that change things?

I find it very useful, but not at all vital. I don't understand what I'd be changing there as the Shelly 1 and 1PM are identical apart from the 'Power Monitoring' aren't they?

Hmmm. Think I'll give that a miss, ta. I guess it is, but it's been working fine for months, no 'overtemp' shutdowns, just the 'overpower' on a couple of occasions, but I've no idea how hot it gets. I fitted it on a recommend from @PeterW, which I hope I didn't misinterpret?

We have a Shelly 1PM controlling when our Sunamp charges, normally overnight. On two separate occasions now it's turned itself off due to "overpower consumption detected" (as reported on the Shelly app and by email). I've check the resistance of the Sunamp immersion and it's 18 Ohms. I think that's 'normal'. I checked the mains voltage in the wee small hours when it tripped out, and in the couple of minutes that I was monitoring it the voltage varied between 249.9 - 250.9V (it's now hovering around 248V). The Shelly 1PM trips out at 3500W. If my Googling is correct, when the voltage hits 251V the Watts will exceed 3500 tripping off the Shelly. Does that sound about right? I realise the DNO can pour 216.2 - 253V into the house and as we are right by the sub station we get the upper end of that range. So, to the main question, is there a small voltage regulator out there that can control the voltage to the Sunamp or will I have to get rid of the Shelly? Are there any other solutions?

Well, if you couldn’t convince her with a Miele I guess all hope is lost! Just out of idle curiosity, what is it about a gas hob that your wife prefers over a high quality induction? About the only thing I can think of that a gas hob would do better is wok cooking.

We used packers on the low spots and cut out the batten on the high spots. We were counter battening so any gaps in the first layer of battens didn’t pose a problem for our cladding, not sure if that would work for you though?

I spent hours researching those and came to the conclusion that, domestically, they were not a good option. I was researching pre Covid so I didn’t see that ‘virus’ reference, but it was all about the fact that air was spilling from the extract into the supply - which was what I was trying not to do, so didn’t go there in the end.

Lets face it. They make the rules.

Our down draft recirculating hob can be reassuringly noisy on its higher settings. It doesn’t stay on the high settings for long and soon just becomes a part of the general kitchen hubbub. Are you listening to your noisy hood in an otherwise silent house? Now you’ve got the recirculating kit you may as well live with it for a while and hold off drilling that big old hole through the wall until the noise really does become an issue. I’d hazard that it won’t be.

+1 to the induction downdraught hob, trumps a gas hob in every way (except price I suspect) and is so much easier to clean.

A match made in heaven?

@saveasteading Can’t find the one I bought but it was something like this Came in a protective case full of Wizard magic that stops it sticking to stuff when you don’t want it to (like the inside of the delivery van).

Got mine from Amazon. One big bugger and lots of small ones so when you’ve found a nail/screw you can pop a smaller magnet on it to ‘mark’ it. Probably overkill as a pencil would clearly do just as well! I’ll see if I can find the link...

I use one of those super strong magnets (idea nicked from @Jeremy Harris) it finds the fixings in no time. I wrap it in a wet wipe so it doesn’t scratch the finish and is easier to pull off when it’s found it’s target.

@Conor We have 20mm porcelain tiles on pedestals for our patio, seems to work fine.

It clearly varies quite a bit. Back in 2018 ours was £1093 to disconnect, we then received a £240 rebate as it was ‘cut off’ in the track outside our boundary and no road needed digging up. So, £853 to disconnect (no reconnection).

Yep, good point.

Very similar situation to yours. We cut ours off and it is terminated outside of the property. Would that lead to a standing charge? Not heard that before.

Also no expert and NHBC are just an insurance company (I think?) so they’ll try to dodge anything, but if the building hasn’t been built to the standard specified, which it sounds like it hasn’t, surely they have some responsibility?

@Littlebig I guess the house is still under NHBC warranty? It sounds like it hasn’t been insulated to the levels required by building regulations - if at all - in and around that bedroom. I’d kick up stink if I were you. Do you know anyone with a thermal camera?

Pedestals would definitely do it, and on a concrete slab I wouldn’t have thought it would be too problematic. I’ve used pedestals on a compacted base of type 1 and a bit of sand to level than as we didn’t have the articulated pedestals. Whilst it’s taken me an age, problems haven’t been too many. They’re not cheap, but not massively expensive either, however if you change your mind about any aspect of your patio (which we have) it’s really easy to start over, for example we decided to remove two tiles and put plants there instead, we dug out the type one to make a hole, lined it with some leftover geo textile membrane and planted away. Really easy to do with pedestals and equally easy to reverse. (It’s still a work in progress, but the olive tree has been pruned!)

We’re probably going to use the same microlouvre for our three easterly facing windows that don’t have external blinds. I was under the impression that once fitted, they stayed in place? I imagine that they would be quite vulnerable to accidental damage stored in a garage or do you not think that would be the case?
