KaKu doorsensors not working

[Andro]

So last week my domotica server experienced some problems and I decided to install homeseer again. Everything seems to work, but I can't get the RFXcom receiver to pick up the signals of the KAKU door sensors. The former installation had no problems whatsoever, but somehow this one won't. It does receive (and send) the KAKU plugin modules.

Anyone have any ideas why this could be?

Enable the AC protocol in the receiver configuration.
To be sure the receiver is correctly initialized enter Modify-Save for the receiver with AC enabled.

did that... doesn't work unfortunately.

What I did notice that it could find the sensor when I removed the battery of the sensor... but it didn't do anything after that. Battery is brand new btw.

The KaKu doorsensors are not very reliable products. I also bought one but threw it away.
I use normal X10 doorswitches now.
I have no problems with the other KAKU transmitters.
