How to use webSocekt Server with custom source System (Custom Agent)?

pco-protocol.txtTo connect a machine with a crude network interface to our ME system I wrote a custom agent. For monitoring purposes I'd like to use the websocket server along with the ME-Target system.

I am able to create a remote subscription from a browser but the value is not updated after the initial send. The protocoll tells me, the remote alias is recognized as out of the deadband range. (See attached log-extract lines 9 and 10) After that nothing happens.

A "working" OPC-UA agent would show an entry "Expression evaluation completed" from "Notification" in the next line. However, for the custom source this does not happen.

What am I missing? PCo installation is version 15.1 Patch 9
