JimTurner Posted February 3, 2021 Posted February 3, 2021 (edited) Poked around and did not find an answer. I have an ISY994 along with an Eero hub on a UPS. My issue is, I had a power failure that extended past the UPS support time. When power was finally restored, the ISY was inaccessible by any means. I am assuming it booted before the network did, and was not able to obtain a DHCP address. I unplugged the ISY and plugged it back in, and then it was addressable. I am wondering if setting a static IP in the ISY would solve this? If so, do I need to set the Subnet Mask, gateway, and DNS boxes? Eero uses 192.168.7.x IP scope. Basically I want to fully auto-recover on power restore without any manual intervention. Thanks! Edited February 3, 2021 by JimTurner clarification
larryllix Posted February 4, 2021 Posted February 4, 2021 I had that same problem a while back and resolved it by using a reserved IP address in the router DHCP reservation table as well as the same static IP address in ISY. Since I have discovered my router would not handle more than about 51 IP addresses (I have 26 WiFi RGBWW bulbs and strips), and I bought a new router that seems to handle 75 devices OK now.
