Domoticz

I got my self an 433 door/window contact sensor from china, link http://www.dx.com/nl/p/Original-KERUI-D ... t4ALsiFO9I

However now i am stuck as i cannot add this sensor to domoticz. I have tried 'Manual light/switch' with various types such as X10, IT.. with no luck.
I did not buy the little remote as i thought adding can be achieved in domoticz directly.

Any suggestion, tips before i buy the crappy remote which i will never use.

PS using RFXcom, and do have KAKU remote which doesnt seem to work with this unit

enable Lighting4 and enable "Accept new hardware devices" on the Setup - Settings page.

Note: it is preferred to use the D026 as this sensors has an Open/Close status. The D025 has only an Open status.
