January 7Jan 7 I have been running a full blown Insteon 50+ devices system on ISY 994i for nearly a decade.The system has proven to be reliable. Maybe once every 6 months or more I might find a device that did not turn off or on at the scheduled time, but that is very rare. I replaced the PLM after maybe 3 years but modified the replacement by drilling a dozen holes into the plastic case so there is airflow through the unit. The PLM has since been solid.The system has functioned so well over the years I decided to upgrade to the EISY R2. In a nutshell the upgrade was very easy. I simply made a backup of my 994 saved it to my local PC. Disconnected the ISY, Replaced it with the new EISY R2 with a new PLM cable. Running the ISY Launcher on the local PC located the EISY, I did a restore from backup. It booted and came up with all my nodes and programs intact. The only thing I needed to change was the EISY tome zone.Good job Universal Devices.
