My device was back up this morning with the correct firmware, not sure what changed from last night. All I did was check the router to make sure the IP had not changed for the ISY-99, then when I went back into the device, it not only accepted my login without error, the firmware version was correct. Wonder if a port was being block by the firewall and opened after a timeout period. I'll have to create rule to make sure that does not happen again.
For the request failures, I will move the PLM around the house to see if I can get better connections to the switches. What device are people using to clean the line noise?
Thanks
