I just got the solution:
When ur running Minepeon on your Pie, you have to change some code in the web ui:

#!/bin/bash
/usr/bin/screen -dmS miner /opt/minepeon/bin/bfgminer --http-port 8330 -S all -c /opt/minepeon/etc/miner.conf

After saving this and restarting the Pie u can set the Blades up with ur Pies Ip and the port 8330 as mentioned in the code.
Here is a picture of my current hashrate, seems to work quite well:
