I wrote the plugin. I hope to have the config app done this week, and then I'd be happy to let you try it. It creates HS devices that wrap the 1-wire funtionality. For example, my Garage Door Control HS device consists of one 1-wire input, and one output. It shows the status, and has an Open/Close button. The motion sensor HS device shows motion/no motion, and I'm using events around it to turn lights on/off.
The plugin currently supports the relay boards from Hobby Boards & Midon Design, the 18S20 and 18B20 temp sensors, 2405 and 2406 I/O, such the Hobby Boards mini motion sensor, and the Embedded Data Systems IO boards.
I'm going to be using a lot of relays to control window & skylight shades.

What HomeSeer plugin are you using to read the motion sensor?
