there are 1-10V knx output modules. Another option would be to use a DALI/KNX interface.
I haven't been able to find any yet, do you have a suggestion of one?
Ok, I haven't really dug into DMX (haven't even heard of it before, actually). Does it have the dimmer modules or the analog outputs that can be integrated into KNX? Is it a lighting network only?
In case this is of any interest...
We're testing some pre-production ZWave load controllers that will dim standard GU10 LED replacement bulbs... Should be available later this year. We have seen a ZWave controller pre-production unit that will dim fluorescent lights - it needs an N feed and supports both 0-10 and 1-10V control wires and will be rated around 6AX. Again should be available later this year.
All the best
Sounds interestning, I was up for zwave, but everyone here seem to think it's a better choice to prepare the house for a wired bus system I'm searching for wired products matching led. But it's very nice to know there are coming more products modified for led lighting
What price will they land at?
BTW, does anyone think it's better to leave some parts of the automation to the wireless?
Motion detectors, fire-alarm's, thermostats for floor heating etc.
With knx I believe the standard accepted way is through a Dali/knx gateway, as mentioned by hari. You can get gateways, on ebay to control 64 Dali devices (128 in total with 64 mirrored etc.) for between £100 and £200.
As an aside the much maligned Heathrow terminal 5 building (which is not much maligned for its lighting) uses KNX/Dali. It's a very commonly used commercial solution.
Personally I felt that it was overkill for my house. I have fixed LED's (for example on the stair treads) which I switch with an ordinary output turning on or off the power supply. I have ordinary light fittings (including lamps) with fixed bulbs, which are all with non-dimable eco-bulbs, that are switched with ordinary outputs. I have ordinary halogen bulbs, again switched with ordinary outputs. I create lighting scenes by turning on, and off, a different pattern of lighting, not by dimming. It was a design decision we made.
To achieve this I have wired each power socket (and light fitting) individually back to my wiring cabinet where it is switchable by an output (on the live terminal). I felt that I didn't want to deviate from a standard device for each light fitting - so I wanted to keep them all 240V switchable, not dimable. I don't preclude the possibility that I may want to change this down the line. If so I need to just replace my ordinary outputs with appropriate dimable outputs in my electrical cabinet. The point? Well, I would say that initially your wiring scheme is more important than actually how you connect your devices.
If cost per output is an issue to you it seems likely that you might be somewhat limited on the scope of complex lighting that you end up using.
Intriguing to hear about your setup, thank you for sharing
I know that switching outputs will be both easier and cheaper in the initiation, but I hope it will pay off in long term and that I will enjoy the smooth light-up and light-down it will lead to and less energy costs too.
Cost is always an issue, but I need to know how cheap I can get away with what I exactly want and then weigh if it's worth the money
If I didn't enjoy the technology I wouldn't think of automating the house, because I really think it's more a cost than a saving. In 20 years when I hopefully will have had a great time of living with the family in my house I don't think the automation products will be worth anything anyway when selling. But that's just my way of looking at it
