Open SmartHome System "Prototype for Everyone"

Well then, back to the technical questions: - How do you switch sockets where, for example, a hairdryer or vacuum cleaner is supposed to be operated? The Controllino is only allowed to conduct a maximum of 6A, i.e. 1380W. - How long do the relays last if more than 6A passes through? A circuit breaker does not trip immediately, but only after a certain time, sometimes after minutes, if you, for example, draw 8A. - Because of the double outputs of some relays, the circuit breaker should be placed before the input so that both outputs are protected together with 6A. - How short-circuit resistant are the relays? Hang 6A circuit breakers in the circuit and deliberately produce short circuits. Does the Controllino survive that??

Hello hello... no one said that all sockets are immediately switchable (that wouldn’t make any sense in my opinion either). However, every socket will be made switchable (of course not all throughout the entire house, we run at least one 5-core cable into every room = 3 phases. So three sockets/groups can be switched per room)

Certainly the Controllino is not optimal for switching sockets, it is primarily intended for lights and possibly blinds. (Small consumers)
Blinds may possibly still be replaced by inner (inside the window itself, so between the panes!) blinds / I-Tec shading from Internorm. That depends on the offer (it would probably be controlled via i-tec SmartWindow + appropriate binding)

An Eltako would then be suitable for e.g. the socket in the bathroom for the hairdryer (if one wants to switch it)

Attention: Not every one of my statements is necessarily still true tomorrow. The system is currently being developed and adapted! This week: lights, next week blinds etc., then other sensors follow (PM, CO2 etc., then the GUI for it)

First, the excavator is coming in about 2 weeks. That takes priority

Sure, I understand that this is actively under development and changes occur constantly. Still, the question of short-circuit resistance is very important. An LED lamp may be a low-power device, but as soon as a short circuit occurs, current flows. Really high current. Therefore, the question of operational safety is fundamental and all these questions need answers, otherwise the marketing of the system will fail. In the worst case, you are liable.

Blockchain is not just about storing information forever. Through MAM/Streams, devices can be securely controlled remotely without relying on any server. You initiate a transaction in the blockchain with your phone, your front door monitors the blockchain for this transaction and then unlocks the door. This way, no "gap" needs to be opened in your home network, but you can still open the door from anywhere in the world with your phone. Through Smart Contracts, the control of absence/alarm systems could be made secure, etc. Of course, this is not a must and can be solved in 10 other ways that have existed for 10 years, but it is precisely that: another way to control without relying on a provider.

What you describe all works perfectly well without blockchain and has done so for decades. Secure for home and house and also your data.

Completely without any providers.

Also here no advantage through blockchain but only unnecessary complexity. It is another way that nobody needs and that nobody asks for.

I will quote myself right away:

Of course it’s not a must and can be solved in 10 other ways that have existed for 10 years already, but it is exactly that: another way to control without relying on a provider.

Whether it is more complex or not, everyone must decide for themselves. For me and many other interested users by now, it is not.

It is another way that nobody needs and that nobody demands.

The same was said about the car and the personal computer.
