I'm the author of this program so I thought I would step in here for a second. PowerPatrol is designed to work with the HP1 and allow full editing of systems, favourite lists etc. As of this writing, we are still building it but hope to get the first version out in the next couple weeks. The first version isn't exactly going to have every feature under the sun, but as time goes on more features will be added and it will be continuously improved.
PowerPatrol is going to be a Freeware program and is designed to work in conjunction with Home Sentinel (HS is still used to download DB & firmware updates, for now). To download the program when it becomes available and for additional support please be sure to visit the official PowerPatrol website at scannow.org . Also available on scannow.org is FreeSCAN for Uniden DMA scanners.
