I purchased a 2448A7 USB PLM and a Polisy Pro the day Insteon turned off there servers. I spent this morning and most of the afternoon setting things up. I have about 30 devices and everything, including Alexa integration is up and running. It was a bit of a pain having to do the work that was spread over 8 years of adding devices in a single day, but well worth it. I am pleased with the product and the tools UD provided.
