> 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…

Also, in quite a few houses, the initial run of water out of the hot tap is cold for quite some time until the hot water has either made it round from the hot tank, or if you have a combi boiler system then after that has fired itself up, got up to temperature, and then the hot water has made it round the pipes from there. It may be that the washing machine uses so little water that most of the water it gets from the…

I'm curious, how do people record the history of their adventures like this? I assume this doesn't all come from memory. And writing some kind of diary for everything you mess around with must be hard. Or is it common?

  mknote () {
   emacs -nw $HOME/notes/`date "+%Y-%m-%d-"`${1}.txt
  }

  $ mknote FooTopic

  enote () {
   local newest=$(ls -Ft $HOME/notes/\*.txt | grep "$1" | head -n 1) 
   emacs -nw $newest
  }

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

These are embedded devices, they do not need this complexity… Not surprising at all. I would expect that a lot of these are bought as retrofits, and not as a part of new construction.

> Running wires through existing walls can be annoying, and they don't want to put that barrier to sale in front of them. It also makes it more convenient to compromise the device from across the street (or across town with a directional antenna). Though of course that's not a problem if your security is up to par and the device continues to receive regular security updates, and we can only surmise that the author ha…

I like how the author is surprised by the technological aberration that form Linux powered home appliances. A node server to power and publish over wifi a web site, an API, a web socket, while the site is being displayed by a outdated webview engine within an heavily constrained terminal which cant be reused for anything else. That's... the norm. All this is very common. And yet displaying a couple of digits and a ba…

The LCA of the solution must be consterning as well, especially compared with few one dollard microcontrollers. At the average cost of electric in the USA this amounts to under $2/month.
