i have an Insteon 2413U. I suspect most people using Indigo+Insteon do also. This device is both the central master device in the Insteon mesh as well as the interface used by Indigo. I've had at least two (I think three) interface units go bad over the years in my system. Other friends and family who use Insteon have had the same experience, so this is not a fluke. My current one is old (>5yrs).
If mine dies tomorrow, I can't get a replacement - not from Smarthome, not from Amazon, not from E-bay - not new, not used, not refurbished. In fact, I'm starting to doubt whether there will be any new more new Insteon-brand devices manufactured and sold.
I know repair by replacing some of the components on the circuit board is sometimes a fix, and I'd probably attempt that.
Any chance Indigo will support the Nokia Lighting Smart Bridge? Are there any other known alternatives?
What do people see as the best long-term path for keeping legacy network of Insteon devices alive in a future world where other HA and IoT stuff moves to Matter - will there be enough market for someone to make a "bridge" device that makes legacy Insteon (and maybe z-wave) devices show up in a Matter network?
I don't feel ready to simply "write-off" my Insteon devices, of which I have a large number and many are "built-in" to some degree.
