I was scanning Reddit and noticed a completely ignored link to Hoobs. Also for a link to a claimed conversion of the Insteon hub to a PLM by replacing the ethernet circuit with a USB interface.
UD may ban me for this.....
I noticed my HubPro data is gone in the Insteon+ app the other day when I was no longer able to add a switch using the recommended "manual" method. I wonder if same happened to the other hub's data. All of my Insteon devices that HomeKit already knows about still work, though.
