It is completely reasonable if the heat system every so often "phones home", so report on usage, but it shouldn't actually stop working, if the network connection isn't available.
You can blame, DDoS, hackers, network outages, the Russians, I don't care, it doesn't cover up the fact that your system has a stupid design.
1) So they can bill you. 2) Bad design
Billing is almost always the reason if the design is sane. And it's always a PITA.
Bad design is self-explanatory. Most programmers think in terms of features rather than function.
I have this discussion every day with people creating battery operated IoT devices.
Me: "What is your most important function?" Them: "Well, we need to do <feature X>" Me: "<sighing> No. Your most important function is to protect your battery. If the device is dead, nothing else matters. Nobody should be able to make you drain your battery without your permission. After that consideration, you can do something useful."
They didn't even have a firewall.
2. Everybody can be smart after the case :) I'm sure now the'll design something more safe.
How true is this? Every Finnish person I've ever met has mistrusted and feared Russia.
What I CAN see is the glee on the Russian discussion boards whenever an incident like that is mentioned in the news. It's either that or outright denial blaming the Finns (British, Estonians, etc.) for making these claims up out of "russophobia".
You said you are OK with event, which can cause a war, and you dislike Putin.
I'd be quite interested in their perspective on world politics. My impression is that Russia has a lot of propaganda and filtering of the media, and I assume it has a different character from the propaganda and filtering of the media in western countries (... where it happens just as well, but in a more decentralized, money-oriented fashion).
To clarify: I'm not fan of Trump, but I glad to see such reaction.
They frequently bring up how they beat the Germans and the Russians in WW2. And how Finnish vodka is the best. And how it sucks that the world's most popular sauna heater is made in Sweden, because Finnish sauna heaters are superior.
Of course after Trump, the general feeling about US is pretty close what we think about Russia...
That said, no reason not to be careful after what has happened in Ukraine etc we should of course be careful: Russia can wipe out half of Norway just by turning around while they sleep.
That's why we try to be friends and we continue to be part of NATO
The civil war may or may not have been part of the plan, but the primary Russian goal was to secure their supply route to the Black Sea naval port.
A port that Ukraine had been happily leasing to the Russians since the dismantling of the USSR.
There are no such reason for Russia to enter Norway. They already have Murmansk as a naval port, and they export way more oil and natural gas than Norway.
Yes, but this is the kind of basic issue that everyone designing any sort of networked system should be aware of. The network is not reliable, and if you assume it is you're just setting yourself up for failure.
In essential systems you have to build for robustness over efficiency.
The management system can then receive information and MAYBE control some aspects of the heating system. If you remove or crash the management system, the heating system just reverts back to being a "dumb" heating system.
My question is: Why in the name of all that is holy does the heating system stop working just because the remote management interface decides to reboot?
This has to be design by the same idiots that believe that an in car infotainment system should be hooked up to the drive computer in a Jeep.
If there's already a fire present, whether furnace decides to stop operating or not is usually irrelevant (you can get a gas leak from a damaged furnace even if it's off). I do not see why _remote_ control should be able to prevent a fire from starting: whatever is remotely controlling this furnace doesn't have more data than the furnace itself.
So, in this case, "burn at max rate" _is_ the safe setting to be used when the controller dies. The only unsafe situation that it will cause is that the hot utility water will be scaldingly hot, but there will be no increased danger of fire nor of CO poisoning.
