Some time in the last 8 hours, something really got noisy in our house. We have a V3 (UI5) and a V+ (UI7). Devices on both were working 10am this morning. Noticed at 2pm that a scene had failed to turn on our greenhouse exhaust fan when the temperature warranted it. Tried actuating the GE outdoor relay from the GUI, nothing happened. So I went out and swapped another in for it, and turned it on via the relay button. Brought what I believed to be a dead relay in (althought it also turned on/off via button), but then noticed that the swapped-in guy showed “off” in the GUI, and I know it’s on…I can hear the fan running.
Looked at the UI5 GUI, and a lot of stuff being shown ain’t true. Tried turning on/off various things, no luck. Have powered cycled, done soft zwave reset, restored from backup…nothing makes any difference.
Then I looked at the V+ UI7, and it’s showing that it can’t talk to some of its devices. It’s more intermittent, but it’s mostly hosed.
These two things abruptly failing together makes me 99.9% sure that something is sending out so much garbage that the network(s) are now unstable. Here’s my question: any good suggestions on how to find the villain? We have 40+ devices on the network with the V3, and a dozen on the V+.
