I'm getting the same thing. Several of my WEMO devices are still working, but 2 of them are "Offline".

Am following this thread to see if someone can figure out what is happening....

I am having the same problem. Maybe

Man now I can not get the app to work at all. When I go into I get this... but the wemo devices seem to be working, just throwing a lot of errors. Bummer since I was going to add a few more.

Looks like its trying to convert an IP address to Hex?
private hexToIp(hex) {
[
hexToInt(hex[0..1]),
hexToInt(hex[2..3]),
hexToInt(hex[4..5]),
hexToInt(hex[6..7])
].join('.')
}

seems like the issue is being discussed in Wemo Connect App error
