I don't really get his point. Wifi is super cheap. You can get a full stm32 with builtin wifi for like $6 for a single one. Installing a cable would be far more expensive in labor.

He's a software engineer not a electrical engineer/electrician. Before I worked in building services I would never have imagined the astronomical price some contractors charge for labour. Have you never assumed anything in your whole life?

I think even people who don’t have diabetes could benefit from this. Would having access to my own glucose levels throughout the day give me some insights into how what I eat influences my own mood, energy levels etc?

You absolutely can, but having a needle in you 24/7 isn't the most convenient thing, not to mention the cost when it's not covered by your health plan. There's one theory which is that the most effective form of weight loss might be simply to always keep blood sugar below a certain level. Still just a theory, though. It's possible that sometime in the next decade the Apple Watch might be able to monitor glucose level…

You can buy something for 130$ or 70€.

Still I wouldn't bother, watching a YouTube video on sugar should be enough for everybody

A few years ago I came to the realisation that if you want people to be more environmentally conscious or economical in terms of utility consumption, (electricity, water, gas, etc), they need far better data than a single figure per month. You want to be able to see usage to a resolution of at most 5 minutes. That way people can spot things like “having my electric heater on for those couple of hours used more electr…

It's ridiculous we don't have unlimited free or almost free energy, the future truly sucks.

Likewise it's ridiculous devices are not automatically saving energy when unused, it's such a simple change it should be standard.

Asking the user to worry about it should not be needed. That's the goal we should strive for. For now monitoring will have to do but I think a combination of solar + iron air battery will make everybody living in a sunny-enough place independent from the grid with ample margin - and we can supply the rest with nuclear.

I always wondered why we cannot find hot filled appliances in the old continent. Also, I wonder why compressors in heatpumps are not multi-speed (basically energy consumption can be modulated). If you are an expert please let me know I'd love to talk more.

> I always wondered why we cannot find hot filled appliances in the old continent. You can find them but they'll be in the semi-professional space and above (relatively expensive high-duty). They're very rare in the consumer space because - it requires running more hot water lines / extensions, historically houses are built with lots of cold water lines but hot water lines only where required - for their heating requ…

> 50-53C is common to avoid risks of scalding but some are set as low as 45

Wait what, isn't the minimum temperature where Legionella will die around 60°C? Are you talking of a country where they (noticeably) chlorinate the water? I thought that was very uncommon, except for Southern Spain and Italy. If you set your boiler to 45°C in a country with (nearly) unchlorinated water you'll have a nice Legionella culture after your 3 week vacation.

What luck that the author found the single IoT device out there that's a cobbled together piece of bodged electronics designed by a graduate from a webdev bootcamp with a Corel Draw focus. A device that, while only ~15 years old is not only hopelessly useless, but also obsolete an…

You're going to care when you wake up one day and find out you can't buy health insurance because of your data.

See this is the kind of thing I’m talking about. To me, you’re like a digital prepper. You have a bunker full of canned food and guns because you think “you’re gonna wake up one day and …” So be it. The way you live your life doesn’t negatively affect me so do what you gotta do. But maybe you don’t have to prep. Btw, rationally speaking, those who opt into monitoring their glucose are going to be much healthier by se…

I understand what you mean and I agree with you that one cannot prepare for, and shouldn't worry about, every possible future scenario. But is the scenario I'm describing really that far fetched? I'm honestly not sure.

That seems really low. Most houses in the UK have a 60 - 100A supply. Just my stove alone can draw about 7.3kW - about 32A.

Probably depends on the country. In Italy we usually employ natural gas stoves and we use natural gas furnaces for heating, so normally you get a 3kw to 6kw max inbound power. I think you can easily get to 10kw, but above that it's quite difficult.

That's interesting. I wonder if that's part of the reason why electric car uptake has been so low in Italy? Most houses here in the UK have enough capacity to run a 7kW charger alongside other household stuff. My house electricity supply must be 50 years old and 80A (about 18 kW) - so it's not even a recent thing. Do people in Italy never have electric showers? How much power do they run to a new house?

From a decarbonisation point of view it's a real challenge - the only current path to low carbon living is through electrification of heating, cooking and transport.

Oh yes, what's up with that anyway? I recently noticed laundry detergent companies making some magic "wash in 20 degrees Celsius" product, and heavily advertising it on the grounds of energy savings. I wonder how that works. I'm not sure my washing machine can even go as low as 20 degrees.

My US appliances have a tap cold setting, warms the water 0. 20F isn’t an uncommon water temperature for water coming from the city. Can even go a tad cooler in the winter.

Do you really mean "20F", or was that just a typo?

Because if you really do mean F, this tells me something I didn't already know about additives to the US water supply.

> nobody wants to pay the costly people that can do microcontroller programming The embedded world isn't known for paying well.

Actually competent microcontroller programmers definitely earn way more then bargain barrel front end devs.

You can easily say the same for the actually competent front-end devs.
