Is that the Passive house measure at 50% of minimum requirement - that's attention to detail.

Yes we did that cost a fortune, £2-3k including the pipe and the gas sign off for the pipe and won't now need it as we have decided against having gas but I guess it's there ready when hydrogen is a thing🤔.

People will be people.

So best part of 1000m for a decent shower @Nickfromwales I hope your friend has deep pockets cos he will have deep holes.🤔

I actually don't think you have a problem. I need to find out if the python libraries implement the interrupt driven features but either way as you have the pi doing only a couple of things it will be fine. The problems come down the track if you get the pi doing more jobs and loose track of what is happening where and when in the system.

Close them at the outer end but also protect the cables there as they can be chewed through. I have, in the past used stainless steel wool, oven cleaner type stuff, forced down to simply close the gap, this can be pulled out if needs be, does not rust, allows a little air flow - if you want to seal it to air you have to work harder and cannot be chewed through by your average rodent / vermin!

This won't and pretty soon your corner of the country will be ideal Panda habitat. Or not so slightly - if you subscribe to such things, I don't but its fun reading the output (politest way I could put it) then this article will put you square: https://www.dailymail.co.uk/sciencetech/article-7772477/British-gardeners-urged-NOT-grow-bamboo.html#:~:text=Like the notorious Japanese knotweed,and even cracks in concrete.

This is a great little device, and I will build one but using a WEMOS D1 Mini device, however I guess there must be a rate limit somewhere in this version and if you add in additional meters it will arrive much sooner, if its coming at all. Several concepts could, but don't think they will, indicate that although a terribly simple and reliable idea it may fail in exremis. I am not saying any of this is a problem for this system as implemented but it may be if you extend it without getting to grips with the nature of real time systems. Firstly the RPi OS is not really a real time system so although the quickness of the hand deceives the eye it can only do so much in a given time and probably cannot do things at a given time! You can programme it to give priority to aspects of the code but when everything is competing this become a real art - games programmers will tell you this is their biggest headache - my fraction of the CPU is this and spread over.... Real Time OS's do guarantee timings, it is the definition of a real time system that time critical events are handled. This all means that although the RPi will probably do this reliably it may miss a pulse here and there while it is busy housekeeping - a headless system will take less time doing this naturally and this system is not being asked to operate at very high speeds (See below) So, secondly, how fast does it need reliably to be. Most people have a 100A connection so if one was running that flat out (Approx 17Kw {240 x .707rms x 100A} of resistive stuff running) those pulses are going to be coming reasonably quickly, perhaps 5 pulses per second, and you might worry that your Rpi, usually running with Raspberry Pi OS, is busy doing some housekeeping while a pulse comes and goes without being spotted. This is assuming that the GPIO library does not implement any interrupt based process - if so all this is tosh - someone will tell me (See link below)! The sampling is not really a problem of the frequency of the pulses but rather their length, how long are the pulses anyway? If I can find a photodiode around here I will have a look at my meter and find out! Do they change length depending upon frequency one also wonders? For now I am going to work on 30ms pulses as a guestimate. So you need to guarantee your sample rate at least meets the Nyquist criteria (I was always taught that simplistically you need to sample at least twice the highest expected frequency / period to be reasonably sure you spot everything). So this means you need to sample at least every 15ms to be sure of catching a pulse of light. Rpi can sample at MHz so sounds like no problem but with an non RTS OS you might find that the writing of that CSV file actually takes a period of a of 15ms and you may have missed your pulse. The good news is that even if the libraries don't implement the interrupt driven GPIO functions you can still do it and there is a very good explanation of all this here: https://roboticsbackend.com/raspberry-pi-gpio-interrupts-tutorial/ This world we are living is getting increasingly demanding of the union between mechanical, electronic and software systems. So if you can get the electronics to do some of the work the RPi does not have to be so real time. I think the Rpi has a PIO that can be set up as a pulse counter which you can just read anytime, count the difference - measure the time between and it recycles at the top but I may be wrong on that one.

I have this extractor and with the sander attached you can send plasterboard drywall skims over your lunch no problem. I got it 2nd hand so not ridiculously pricey and it works well. Bags are costly though!

Clever - a hidden lintel.

Except at le Weekend! Seriously though if all 30 million French households implement this surely the savings will be valuable, most savings are when you multiply them by 30 million. Of course you have to think of the greater good not just your own personal enrichment / aggrandisement.

On the contrary we are all crying cos we pay 2 or 3 times as much for our electricity as you do and pretty soon it will be even more. So you are the one who should be laughing.

I hope it will enjoy its freedom.

Looking good - not sure I get how the lintels across those opening work but I guess you can see that better from the inside.

Respect - getting that bang on over 2m!

Welcome to THE forum for people like us! Can't really see what a big thermal store brings you here unless your electricity has a night rate or some such to allow you to move the demand window. As @PeterW says if you just need DHW to be stored then you only really need that at a worst case volume, rather than vast amounts of losses in a big system, and you can always fit an immersion heater to top it up quickly if needed.

Ok so you learn something every day don't you!

I already had a blog so it was just a new entry the whole thing worked out of the box.

How does he fix it, by creating a category or an entry?

Ah - that's interesting, more to follow there will be an easy answer to why Steamy's blog does not allow comments?

Yes I thought so. You wonder how many other similar issues are out there - Italian bridges notwithstanding!

You have chosen a good day for it and a bad day to be without it😁.

Seems like a plan.

Worth a look, if you can stand it, to learn how not to build in problems. https://www.bbc.co.uk/iplayer/episode/m0018t7t/why-buildings-collapse#xtor=CS8-1000-[Promo_Box]-[News_Promo]-[News_Promo]-[PS_IPLAYER~N~m0018t7t~P_WhyBuildingsCollapse_SEG_PNC]

Yes @TemperanceNI you need also to prepare for that aspect of the build. Smooth is NEVER the word in self building BUT it's great to see progress.
