The system does exactly that - But that is done automatically without intervention.
The system recognises by checking on our devices and the presence detectors if we are at home. If we aren't it reduces the temperature.* Then it looks into our calendars when we can be expected to be back and increases the temperature accordingly (additionally once we enter a certain Geofence).
*:The overall heating effort is also based on the current and expected weather and sun-influx,as I have some rooms that basically heat themselves when the sun is out. The system is using that effort to adjust shades (e.g. it would allow a lower living room temperature in the morning after we left when it knows that there will likely be a sunny afternoon heating the room without the need to add external heat)
This is what I mean with smart: A smart system is only smart if the user doesn't have to fiddle around with it. Everything else is a remote.
(My next goal is to add personalised heating. I want the system to recognise who is/comes home and adjust the temperature accordingly as my wife wants other temperatures as I do. O can do it room based, e.g. the kid's room is adjusted according to the kid being there, but overall I am not quite there yet)
The good thing is: You can easily replace OpenTherm with KNX. Afaik there are Gateways that mimic Opentherm towards the heater so you can use KNC for the actual control.
No,it isn't. But no open and local solution will be - but you pay for that in terms of long term usability, resilience and data. It's a choice a mature customer needs to make. Be cloud and manufacturer reliant,invest the time to do it properly or pay someone to do it.
And KNX.org works for me(even tried it with a VPN to be sure) - and do you really think that a standard that is supported by the largest companies in the field(Siemens, ABB, Bosch, Schneider, etc.) and has multi-billion of installations in professional buildings alone per year is not for the long term?
The thing is: The standard itself is rather well designed and didn't need too much updates (they just extended the possible packet contents in terms of possible parameters - which technically isn't that necessary as you can fall back to ASCI).
The last major updates were more towards extending functions (KNX over RF), connecting locations via IP tunnel, and securing the packets themselves (which is not really necessary for single household installations but VERY much for multi tennant installations).
The major strength of KNX is the bus packet system itself - as the packets are standardized there are only a few attack avenues. An attacker could flood the bus with packets, try to update with fraudulent code (if none did put a password on it) or try to put fraudulent content in a module that accepts ASCI packets. The problem is the access - the attacker would need physical access or the IP gateway (if existing)would need to be unsecured towards the internet... In the end it is a fairly resilient piece of software.
As someone in the final stages of a masters degree in healthcare management and economics:
Almost. It doesn't entirely cover the costs (at least from the data we have available worldwide, which is somewhat insufficient) but a focus on mental health(which always includes workers rights, women's rights and a few more social issues that create long term health problems on a massive scale) and prophylaxis in general is FAR cheaper than what most industrial nations currently do.
We do have a few issues that are not addressed in these concepts (e.g. end of life care and costs associated with that, new types of personalised medication, accessibility in rural areas,etc.) that still make a healthcare system like that something society has to pay for...But it does improve things massively, especially the quality of life of people that are not the actual patients.
And to add another unpopular opinion:
A smart temperature control is the one I never ever need to use. Because then the room always has the temperature I want.
Neff has a (magnetic/removable*) knob as well. (* Which is a great idea in theory. Unless you have kids. First it's great because they can't start the cooktop on their own. But then you are constantly looking for the knob. A friend nearly got insane...His daughter "accidentally" took the whole fucking thing on a schooltrip to France....HOW? That's why I have the Siemens one with touch.... It's okayish touchwise and it works...)
Haha, no. But I know someone who was part of the OpenTherm development.
To quote him:
OpenTherm exists because Plumbers don't trust Sparkys and Sparkys don't trust plumbers.
OpenTherm is easy to install but "stupid" as hell and not adaptable to modern needs mostly, especially if you consider modern heating concepts like passively heated houses, heat pumps,etc.
That's different from KNX (or Modbus in that regard) - They are much broader in their appeal. Singule use/walled garden systems are always a bad idea,imho.
Get a few components (e.g. Actors, a sensor), a gateway (USB is enough for the start,they often go cheap if you buy used,got mine for 10 bucks) ,a power supply (Meanwell is a good idea) and the free version of the ETS programming tool. (The ETS is the only downside of the system - it's expensive especially for larger installs)
So is windows and Linux if you just look at the year they were introduced.
Just because something is backwards compatible doesn't mean it does not get updates/improved.
And tbh, a light switch does not need that much improvement technology wise.
Tatsächlich muss man sagen,dass auf der Höri oft Tempo 30 indiziert wäre..Und wohl zu mindestens laut einem befreundeten kommunalen Verkehrsplaner aus Singen tlw. auch möglich - aber die Lokalpolitiker haben mit den freiwilligen Schildern halt den enormen Vorteil,dass sie so auf der einen Seite nicht den Zorn derer die 50 fahren wollen (ist ne Goldküste da hinten) auf sich ziehen, andererseits aber auch bei den 30 Befürwortern "wir haben ja die freiwilligen Schildern und ich würde ja,aber Konstanz/Stuttgart/Berlin..." rufen können.
