Devices not added

I try to use this plugin. It adds one switch but there must be more. In the log of domoticz I get the folowing.

`

It seems that the "updateDeviceSettings: Did not find device with key='devicename', value = 'CA2538_MHZ19B_Model'" is not recognized or something.
How can I solve this?
