Now SSS Siedle has system that you guys were doing already long time ago.

As a humidity sensor is measuring humidity of the air and the humidity does not transform so easily through solids as temperature does then I think that you should not cover it. You have to actually consider quite carefully in what place does the reading represent the room humidity the most - I.e. i...

If you did not notice yet then there exist now KNX Opentherm interface module from Theben - http://www.theben.de/en/International/Home/Topical-Themes/Press/OpenTherm-Interface-for-KNX-and-OT-BUS Price is around 200 euro. For example here http://www.voltus.de/schalterprogramme/knx-eib/theben/systemge...

Right, a watertap that requires reading an user manual before operation. Possible usage senario: "Where is the manual, I do not remember how to turn it off.". I would suggest voice controlled watertap. Possible usage senario: "Darling, with who are you talking there?", "Nobo...

In my opinion wireless KNX is waste of money because it does not provide any encryption. But so are almost all other wireless technologies pretty much exept Zigbee. I do not have any experience but my electrician claims that KNX TP (twisted pair) solution can actually work over normal power line wir...

Everything is possible but what is your current experiense with the programming and electronics?

I'm moving into implementation phase of my electricity system and because I desided to do the most of the works on my own with help from my friend and in supervision of the profecional electrician then it appears that I do have more degree of freedom on what to really implement or prepare (compared ...

Zennio 4 sensors input for temperature measurement - 101,15 € (as far as I read the maximum cable length for the sensors is 1,5m, I need about 10m) I think that this is not true. Check this http://www.zennio.com/images/stories/zennio/eng/doc_tecnica/sondas/Technical_Note_Temp_Probes_Eng_Ed1.pdf It ...

Is there a KNX module that can read 1-wire temperature and humidity sensors? There is a product named Wiregate but it is quite expensive (about 300 euro) so I think that it defeats the purpose. Voltus has Elsner temp+rH sensor http://www.voltus.de/schalterprogramme/knx-eib/elsner/eib-knx/elsner-701...

Yes. A power supply.

some kind of central heating control for 5 (or 4 points if the price is too high for 5). I don't need fancy wall thermostats, I just need a DIN module for temperature sensors and thermostat logic (or maybe I could do the logic in some application software that drives relays?). You can consider Zenn...

Eibmarkt links do not work (you actually should replace the session id in the url with the valid one but I do not bother and I'm using eibhandel.de instead). With inputs it depends what voltages you need. I guess that you want to connect switches? Then MDT is not a good option. With a bit more money...

Any domotica solutions to have prove that somebody used these keys to empty your house without leaving a trace? I belive that is would be rather hard to empty your house without you noticing it. But seriously talking, I suddenly do feel urgent need to the key that does use cryptography instead of m...

My personal opinion that not a single product has made it into the normal households. A lot of people seem to have a simple kika set for triggering things like lights outside ... but that's it.. I think that this is not true. There are many normal households that have just used professional install...
