If I recall correctly,
IPLL is for insteon items with buttons
IPLD is for devices (without buttons) such as the inline linc.
In summary, I use IPLD for inline lincs!

I have my first in-linelinc ordered from Smarthome.  I noticed in the MisterHouse wiki that there is no .mht example for these devices.  Do I need to use IPLL or IPLD or something else?
