I've built a script that pulls status of units from the Tellstick and compares to previous pull. Changes will be reported to given IP address. It's not as clean as having the Tellstick report changes but it gets the job done.
The IP of the Tellstick is configured in a config file so it's not required in this syntax. The '1' is for timeintervall, in this case one second and the IP is the address of the server to witch we report the changes.
I use eventGhost as server for my home automation and this sends a UDP message to that server so I can trigger events.
