The ‘anonymous’ you see in the error message is just some JavaScript internal mechanic, nothing about this actual problem. You won’t find the answer there.
Homey tries to access http://192.168.201.170/json and fails on processing the result. As I don’t put the result in the log, I don’t know exactly what’s failing. Could you send me the contents of that page in a private message?
And could you also send me the expanded objects in the “units” array from your screenshot? I’m curious what the content is.
