I/O Module - Low Voltage Controller

Disappointing this is not dual band

Seriously? How long have you been putting out this product and you still don't have a dual band option? It works, but only if you have great power line communication close to your PLC. Open/close sensor is at least wireless, but not powered by line, so you have to replace the battery (but who knows how often?).

I/O

Used the I/O device to control my garage door when I forget my keys are go on a bike ride it’s nice to have the app

Use them a lot

I have 8 of these in my system. I use them for garage doors, driveway gate (the later connected to the gate control board from via one pair of a CAT 6 cable 350' away) and to trigger a number of different things based on specific events. The reason for the "4" rating is because unlike nearly every other Insteon device, they have a shorter life (3 to 5 Years typically) and they are not dual band which means in some situation you need a range extender nearby to perform the dual band function if they are install a long way from the Eisy unit. I do appreciate how versatile they are.
