support for Dimmer with Start-Stop Telegramm #125

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
There are Dimmers (e.G. Hager TXA213) which need a Stop-Telegram for relative 
dimming. Stop is DPT 3.007 '0' or '8'. 
The Advantage of Start-Stop is less Telegramms are needed, only one 
Start-Telegramm and one Stop-Telegramm per dimming. 
It should be possible to set the Dimming behavior (cyclic Telegramms or 
Start-Stop) by Setting 'sendFrequency=-1'

I found this interesting document by ABB:

http://www.knx-gebaeudesysteme.de/sto_g/English/APPLICATIONS/2CDC500051M0202_App
likationsHB_lightingcontrol_EN.pdf

On page 26, you see the 4 bit telegrams for KNX dimming. Moreover, as also 
stated on this page, it seems that start/stop dimming is the todays standard 
solution.

Maybe IncreaseDecreaseType could be extended with an additional STOP value. 
This value shall be sent unconditionally when releasing the button after a long 
operation (in both cyclic and "one-shot" cases). Using sendFrequency=0 shall 
disable the cyclic sending of the INCREASE/DECREASE value.

My suggestion would be to handle these specifics in the KNX binding. With a 
special configuration, the binding itself could regularly send 
INCREASE/DECREASE to the event bus. The EnOcean binding already behaves this 
way and we discussed to possibly extract the so-called "profiles" from it, so 
that other bindings can use the same logic.
