Title: Cheap knx push buttons?
Post by: Raginglynx on March 08, 2011, 10:07:08 am
Hi!

I've been through the eibmarkt site and the voltus site, but I think finding things on both of those is hard.
I'm looking for knx push buttons at a good price. I'm mostly looking for 8-fold (8-channel), but of course all types are interesting. The ones I've found with bus coupler included are at around 150 EURO and I thought there must be cheaper ones.

Or is the best way to realize it in a cheaper way to use non knx retractable push buttons with binary inputs?

Best price I've found for binary inputs are 15 EURO per channel - for an 8-fold switch that is 60 EURO and the button switch itself maybe costs 2-30 EURO at best.

Any other ideas?

I'm planning for a central touch panel, so this is only for the lights, curtains/blinds and so on..

Thanks!

Christian

That's really a big difference to what I've found! :D

Are MDT always pretty cheap even if they aren't on special offers?

Yes, I have found MDT to have the best prices looking around.

Disclaimer: MDT graciously sponsored a bit of hardware for setting up the LinuxMCE demo house I am living in.

EDIT: And it took me quite some time to find fairly priced KNX equipment. Even eBay was sometimes outrageously expensive. And with KNX it really helps to check out REG devices with multiple channels.

Device you can attach to a DIN rail http://en.wikipedia.org/wiki/DIN-rail for example http://www.eibhandel.de/MDT-BE-1600001-Binaereingang-16-fach-8TE-Eingaenge-potentialfrei which plugs onto a DIN rail and gives you 16 inputs into KNX

Yes, as soon as things are complete.

There will be a video tour demonstrating LinuxMCE integration into the house. But this will have to wait for all the work to be completed. Due to a mishap by the heating installer the original grand opening will be postponed to 2012.

Hi Posde,

It was a long time since I was logged in. I'm about to build the house now, starting today actually.
A question about the MDT push-buttons you mention above. Do they include the bus-coupler part?
