Lyndel and Sebastian,

I've got it without the SingleShot module.

I've used Sebastian's library as it is but removed the TOKEN part.

I've putted the library at System level and the script runs every 30 minutes by itself (I've changed it to 5 minutes).

I've used the Big5 HomeSeer plugin, watched the tcp traffic and noticed data.

Then I did some parsing and filtered the Battery Status (as value between 0-100) and the serial numbers of my TSU's out.

Depending on the Battery Status now I can switch on/off a z-wave wall plug or give notifications to my Handy.

Now all is running perfect.

Many thanks,

Fischi
