The first thing you need is UPStart running on your laptop with either a PIM (powerline interface module) of your own or a way to connect to the PIM that's being used by the HAI system.

HAI UPB is not different, hardware wise, from plain UPB - it's simply a structured method of assigning unit IDs and Links, grouping 8 devices into a "Room", etc.

But I digress...

Back to UPStart - with UPStart you can run PIM-to-device communications tests and device-to-device communication tests to determine signal strength and noise level.

When trying to control other devices from a keypad it's typical that communication will be great to some devices and not others. When the communication gets to weak things don't work.

And it can vary with what electrically powered devices are running at any given time.

There are also devices, like a UPS, that can degrade the UPB signal.


So first you use UPStart to determine the current state of affairs and then determine what remedies you need to apply.
