I enjoyed the description of your home automation setup! I learned about the wide range of sensors and devices that can be incorporated, and that technically it's possible for the owner to programmatically control everything. I can see you're riding the edge of the coming wave.

Looking at the differences between the KNX standard and the "Connected Home over IP" project.. From the latter's home page [0]:

> By building upon Internet Protocol (IP), the project aims to enable communication across smart home devices, mobile apps, and cloud services and to define a specific set of IP-based networking technologies for device certification.

This seems like a higher level of abstraction than KNX (unless "smart home devices" in the above description includes the kind of individual sensors you mentioned) - and exclusively focused on using the Internet Protocol.

Reading the Wikipedia article on KNX, it does sound like it has all the elements needed for home automation, including what this new standard aims to achieve.

EDIT: Now reading about the ZigBee specs, I find there's a big overlap in protocols/functionality. As a complete newcomer, it's hard to disentangle the pros/cons of these standards.

Yes I'm riding the automation wave, but only because after working for 20 years as a developer I was finally able to afford buying an apartment and wanted to try to push automation to it's limits. I haven't done it all and could go even further, which is why I like KNX, it's not closed or bound to a single company so I can buy add even more stuff from a lot of providers (see some example of companies in my other comment).

The alexa bridge is not perfect, sometimes it has hald a second of delay. Twice a year the servers are down and it doesn't respond for few hours, but besides that I'm very happy with it. B.t.w. I used this server from PRO KNX to connect my Alexa(s) to the KNX server: https://proknx.com/en/news/2017/realknx-2-0-voice-control-al... (it is also compatible with Google Home as well as Apple Homekit).

Thx for the clarifications about the differences. I don't know much about the KNX standard. I fiddle around a lot with NodeRed (nodejs / javascript) and use some Alexa routines but I never tried to implement the standard myself. As far as I understand it, KNX is also using IP Networks, because all my devices have IP addresses and my servers are open on different ports.

I hope the Google, Apple, ... alliance decided to do create a new standard for good reasons, but I have doubts as I can't find someone that explains me what is so bad about the existing standard. Why Apple, Google and the others don't just join the KNX foundation and why this already open and royalty free KNX standard can be built upon!?
