Insteon with Aluminum Wiring

Insteon with Aluminum Wiring

Aluminum wiring is less conductive then copper so the INSTEON signal may be slightly affected by that but the signal can go a long way on the powerline so the aluminum wiring does not have a major effect in a residential home.  Where it can be problematic it that aluminum wiring is more susceptible to oxidation which would create poor wiring splices and great care must be taken when joining aluminum and copper together.

These splices can affect the signal integrity and create bad/dangerous connections over time.   INSTEON does silver tip the wires on their devices to prevent the chemical interaction that can happen when you put copper wires together along with aluminum.  There is a product in the industry called Nolox that should always be used on Aluminum connections that do not have this wire tinning.
