Vremea a fost mult mai răcoroasă decât ne așteptam, motiv pentru care a doua zi umpleam bidoane și sticle cu berea rămasă – mai mult de jumătate din cât comandasem. Apetitul bulimic în organizarea meniului s-a constatat și la inventarul mâncărurilor rămase, atât gătite cât și în stare crudă. Frigiderul de împrumut e și acum ticsit cu pachete pentru grătar și fel de fel de alte ingrediente. Și vinul a rămas tot mai mult de jumătate.

Prin urmare ne-am decis să dăm în continuare mese în weekend – prietenii sunt invitați să ne calce pragul cât mai des în următoarea perioadă ca să dăm gata toate aceste provizii. Sau cum se spune în Ardeal, „Mâncați, mâncați, că oricum dăm la gunoi!”.

O parte din invitați au adus cadouri deși noi am sugerat că nu este cazul – le mulțumim bineînțeles pentru gestul lor. Celor care nu ne-au adus cadouri le mulțumim pentru că ne-au urmat sfatul și pentru că s-au simțit bine alături de noi.

• it is an open standard (apparently the only one to be European – CELENEC, international
  - ISO and recently adopted as national standard by China). It means the technology
  will survive no matter what happens with any manufacturer
• it is based on technology with some experience. Maybe it is 8 or so years old but
  the principles are there for around 30 years…
• it offers a range of products and applications to satisfy even the most pretending
  end users
• it is possible to link it with other systems such as EnOcean or DALI

On the dark side, I need to mention that most of it is used inside Germany where the
most product range can be found and also sold. As a consequence the English documentation
is less developed than German one. Another problem is that even if the devices follow
similar principles they embody a vast range of functionality that require profound
study of each one. This means the end user will need a specialist to receive advice
from or be prepared to pay the similar price in order to discover the best solution
alone.

My KNX system will cover a vast area of systems such as:

• heating/cooling management that involves automation of valves, A/C units and solar
  blinds. A weather station and various in house sensors are to be used as well
• lighting, with dimmers, stairs lights, presence detectors
• security, by using same sensors as security sensors or action devices when the security
  system is armed
• communication, shortly said, the ability to receive messages from the house and control
  it remotely (SMS, web, phone extensions)
• door entry system, it is not pure KNX but can be easily integrated. For both pedestrians
  and auto
• automatic gardening: measure the precipitation level and add necessary water by pumps…

The beauty is that in time more can be done with same or little additional devices.

Some of the manufacturers involved in my system: Gira, Siemens, Zennio, Theben, Agfeo, ABB, Hager

As a matter of last minute solution, check this link for multiroom audio. It is not
KNX (yet) but I think it can be easily integrated via Gira HomeServer if the manufacturer
will agree to offer an API toolkit: Sonos

After my 1 month vacation I believe I will be able to finish everything in another
month. I already cabled and programmed the upper floor in several days. The basic
things will be done very quickly. More time will require imagining and developing
the smart functions.

I will attend in July and hope will return home with KNX certification.

I was dropping the home automation project after I failed to find a reliable component
supplier. However at some point it happened to find such a supplier so I am back with
this project. The supplier is named Gewiss and comes from Italy. I found a full product
range (namely Chorus) based on KNX/EIB bus as described into an earlier post. No more
technicalities now but it has all I dreamed: the bus management tools, navigator panels,
internet and GSM interfaces, receivers and actuators, burglar system, video entryphone,
etc. It even has some less complicated devices such as wireless triggers and actuators
that listen directly for the wireless command.

Now I found that in Romania there is no company today to offer services around this
system therefore I am up to start learning this area and plan and install by myself
all the system. If it will be a succes, I plan to include this activity as a part
of my future business.
