I’m sure you are correct Drezha, but it is a fact that a lot of the Met Office stations are contiguous with Military bases and wasbit’s comment is quite understandable in confusing Data with Forecasts.
There are in fact a multitude of weather stations in the UK, some accredited by the Met Office and others just interested amateurs who feed their data into a multitude of various networks.
You can get a feel for the numbers by searching on-line for ‘local weather stations’, you will probably find at least one within five miles of your location. Many of these stations also include ‘forecasts’ for the next few hours, but I’ll confess I have no idea how they do this except perhaps look at the wind direction/speed and pick another amateur that many minutes away up-wind!
@Drezha – I have been trying to use Home Automation to link with our Nest thermostat but that then gets into the mess of 2022 Google integration. I’m completely bogged down because I do not have a domain (a Google Cloud registration requirement it seems). Have you any ideas how one gets around this?If you delve behind different forecasts you will often find that they grab the forecast for your area from different locations. This can make a huge difference in what you get, especially if you are looking at hourly forecasts.
I notice for example that the hourly forecast I get from the BBC is often wrong compared with the iPhone forecast. These forecasts come from two different providers, and while the Apple forecast is based on actual location, the Beeb forecast is based on a very approximate area. The Apple forecast uses real time satellite/radar data while the Beeb’s appears to be based on looking out of the Window 50 miles away!
The Beeb forecast used to be much better, but unfortunately became the victim of the Government’s monetary vendetta against the Beeb, so they went to what is obviously a low cost provider.
True – that of course is another US problem they do not have a National Grid – smacks too much of socialism!
To be fair the problem in Arizona is that solar production does not match typical usage. In Arizona most electricity is used in household air-con systems which are typically at max during the summer evening and night. There are also local ordinances against using such excess in unproductive ways. The cure is of course electricity storage but that costs money.
The quick fix has been a local(?) charge to encourage householders to stick in their own storage systems. I put in a question mark because I suspect that charges change with location/infrastructure.
In an ideal world what you say JCD is true. Unfortunately you somehow need to get the single phase 240volt domestic generation out of your local transformer back into the 3 phase 132000 volt National Grid!
Excess domestic production can be a real problem and I believe even now causes problems in parts of Cornwall. A Yank friend of mine lives in Arizona and has to PAY to get rid of any excess power!
We have (or rather ‘had’ a battery with our solar, and frankly I would now not install anything without one. When we installed the battery six years ago I estimated the return on investment as marginal, Even with today’s lower prices it probably still is in the low percents. It does however allow you to take full advantage of the power you get on the mixed cloud and sun days. The reason for this is that without a battery your PV controller will shunt all excess power to the grid, so you go fully on the grid when a cloud crosses the sun, and lose out the excess power when the sun comes out. We have very very few wall-to-wall sunshine days without clouds.
The other thing I would insist on are micro-inverters (i.e. an inverter for each panel) without that any shading of a single panel has a disproportionate effect on your generation. This is however a location/setup specific thing as pointed out in the link
Cloud or local?
It depends if you want to put everything into Google’s Cloud then Chrome, if you want to stay local then Mint or any other Linux distro.
The brand new variant 2.75 seems to be gaining ground in India and Germany.
Yesterday was the first really sunny day around here which resulted in our Solar generating more than we use. We took full advantage of it and trickle charged the car for about six hours – roughly 15 units or about 60 miles range. Unfortunately we would need a much more sophisticated PV controller with a ‘smart’ outlet that only trickle charged any surplus to use the car as a bi-directional house battery.
Incidentally if you ever install a battery for your house think twice before using an LG battery. LG’s support and customer service stinks – it has taken them three months just to send a shipping box from Germany to take back for inspection an under-warranty, 6 years old, dead battery.
Tesla now look much more attractive battery provider and offer a full house UPS as an option. (Every battery ‘could’ do this but Electricity providers demand a certified switching system to ensure that in the event of a line failure their workers are not electrocuted by the battery feeding back into the system.). However, its worth checking how they too service their warranty.
He is an unabashed liar, who will convincingly say anything that will achieve his ends.
He lied in school, he lied as a Journalist and was sacked for it, he lied almost continuously during his Brexit campaign, he then lied as Foreign Minister and during his manoeuvres to oust Therasa May, he then lied over his General Election promises, and lied to convince the DUP over no border in the Irish Sea, he lied almost continuously during his tenure as PM. Even his ‘success’ at Covid vaccination was no success when compared against other countries The UK has twice the number of excess deaths than is the case in France, Sweden etc. Admittedly the US and Russia are worse, but really that does not say much!

I’ve been on the doorstep survey for six months or so, but apparently that is changing. I was sent an email saying that NSO (England) were changing over to a mailing arrangement. I guess it is a cost cutting exercise in England.
Quote from NSO Blog
“Firstly, we are changing the way that we collect our data. …..
Soon, all of this information will be collected online or by telephone, and participants will post their swab and blood samples, or these will be collected by a courier. We are offering participants different options for completing the questionnaire and returning their samples to make sure the survey remains as accessible and representative as possible. “
The NSO stats for England are still available here.
https://coronavirus.data.gov.uk/details/interactive-map/cases
(I have no idea how to get Welsh or Scottish data)
However, due to the Government diktat of ‘Living with Covid’ these stats are now only updated every Wednesday instead of daily. As the Government got rid of the test kits, these stats are obtained from volunteers who are now sent test kits to use and then return the vials. I understand that this may also include a blood test kit in future.
Scrolling along the timeline gives you a pretty good feeling to what is going on. It is a great shame that the Government did not keep the advice to mask-up in crowded places as quite a lot of people I know have come down with it. Although fully vaccinated the infection made them feel really ill, and ‘drained’ for weeks after.
I think there is more Covid around here than at the height of the second wave! I see that most people seem to be infected on the Isle of White and other holiday places.
We are seeing some potentially vulnerable friends this weekend so we will do a lateral flow test the day before. I suppose we should do it on the day, but we wanted to give them a chance to cancel the roast!
Thanks, I have never tried Home Assistant but I will now!
Not elected by the General Public however – so we will have an UNelected Dictator!
Apparently 12% of those over 75 have low sodium levels (8% of those under 60). It appears to me that the medical practitioners who objected to the mandatory reduction of salt in foods may well have been correct in saying more people might die from low salt levels than will be saved by lower blood pressure in the 10% of population at risk.
So Les and anyone else in the low sodium category, enjoy your salted crisps/peanuts but do abstain from taking your blood pressure for a couple of hours to allow your body to handle the salt as it will add 20 points or so to your readings .
You may remember that the
BoeingUS Air Safety Board certified the somewhat modified Boeing 737 Max as safe to fly. As a result RyanAir and others have resumed flying this heavenly ride.Fortunately for us, not all journalists have toed the American line, and ABC (Australia) conducted a safety audit of the first year of 737-MAX flights resuming. In this audit they found that there were at least 22 cases of flight control system failures, including autopilot malfunction, and at least 42 cases of malfunctions of other plane systems, including engine shutdowns, which lead to the partial loss of aircraft control for the flight crew.
These terrifying results have caught the eye of the frequent flyers in the US Congress and they have demanded a new audit to examine the production oversight of Boeing 737 MAX aircraft.
It might be worth checking what planes are booked for your packaged holiday this year, as our misshapen Government seems to have totally ignored this US Congress response!
A quite large factor can be your AV as most now check the boot process and measures taken to avoid side channel attacks on the CPU.
Yep it does, but apparently causing low sodium (Hyponatremia) is common to many calcium channel blockers. Medical Link
Like many medications BP pills work by poisoning you, and may cause unwanted side effects. That is why I suggested to Lee that he carefully read the bit of paper that comes with his medication. If he or you experience any of the side-effects that are detailed your first port of call in these days should be your pharmacy. (I haven’t yet read any script that doesn’t say ‘upset stomach’!)
but also the grand paper chase issue being another.
I have a number of friends who are or were in various public sector jobs (GPs, Teachers,Social Services) bar none they all complain(ed) about being snowed under with non-productive paper-work which is supposed to prove either that they had done their job properly, or to provide some sort of audit trail for management. Normally what was being audited was only of passing relevance to their actual job.
I used to work for a US company that was one of the first to adopt metrics as a management tool (IIRC it was McKinsey that forced it down our throat). We struggled with the additional non-productive work load for years before realizing that 90% of the metrics were useless, and were just Auditor fodder. After some years of frustration our business metrics were vastly simplified, and used purely as a management tracking tool, and a way of focusing on critical issues. Unfortunately I get the impression that our Public Sector systems are still twenty years behind getting to that point.
Integrated systems were one of the tools that enabled my old company to streamline things, but our Civil Service plus Systems is just a way of throwing money into the pockets of favored companies with nothing at the end of the day. Maybe Dave knows of a Government system that works efficiently and productively, but I certainly do not know of one.
