With a bit of luck and hard work I will have my KNX certification in two weeks time.

I am just reading and researching it now. but the options are endless.

KNX is a standard / protocol used by over 420+ suppliers, and scientific groups 1000's of bodies/members. The standard has been developed for over 20 years and used in most of Europe and now America are starting to adopt it. KNX allows integration across multiple platforms from Blinds, Lighting, Heating, HVAC, Security, Intercoms and to a lesser extent AV but it can control it.

What I like about KNX is that you are not tied to one supplier, something you installed 20 years ago will still work today, and in 20 years time...

Based on BUS technology it has many positives including solid and robust performance its only flaw is based on the size of your system and design. telegrams are sent to each item at a rate of 9,600 bytes - remember the old modems 'yes' that speed.

but for turning a light on and off using 1 bit 9600 bits are like lightning, it only can get problomatic on very big installations with lots of telegrams of data being sent (but then you just make use of KNX to IP Routers and gateways and spread the load over Cat cabling).

KNX can be as simple as you like or complex as you want,

Below are some pictures of KNX topology and what it does.

Far better than Lutron and rako in my opinion, done quite a few installs of it over the years (although never the programming ). Well done on getting your certification

I'm studying now, fingers crossed :)

Not yet certified, but I agree it's a very professional way of doing things
 
I'm a RadioRa L1, I though Lutron will become cheeper as other smart solutions comes to the market. (800 US for a Grafik Eye QS its too much for these days)

Its KNX easy as Lutron and much cheeper?

do you think Z-Wave its mature enough to substitute RarioRa 2 or Homeworks QS?

Thank you

KNX is not easier than Lutron, what it can do in comparison is far greater, and with KNX it is a protocol / Lutron is a Manufacturer of a range.

KNX has over 420 suppliers making KNX products. Lutron makes Lutron.

KNX = 1 wall plate to control heating, lighting, AC, AV.
KNX = Smoke alarm goes off you can light an escape path, or open an electric roof window.
KNX = Weather station detects direct sunlight on one side of the building, it closes the blinds.

To name a few examples...

Thank you! I didn't know that KNX was so capable. You made so simple that I want to know more!
Does KNX have a Online training like Lutron LCI?
Can I buy without pass to a local exame?
