Weird; it looks like that status string decodes to:

{[{"No":"1","Cfg":"1","State":"0"},{"No":"2","Cfg":"0","State":"0"},{"No":"3","Cfg":"0","State":"0"},{"No":"4","Cfg":"0","State":"0"},{"No":"5","Cfg":"0","State":"0"},{"No":"6","Cfg":"0","State":"0"},{"No":"7","Cfg":"0","State":"0"},{"No":"8","Cfg":"0","State":"0"}]}

…which of course is not valid JSON. You can't start a JSON document with {[. It looks like they took a proper JSON list and wrapped it in {curly braces} for no reason?

I guess we could detect the error, try just stripping off the { and }, and try again. Or we could pass a special flag just for the "zones" configuration that does that.

Since we have determined that LG can return a json wrapped in curly braces, I think detecting the error is the best long term solution. You never know when other json results might come like.

This is easily fixed by checking for such malformed json and than apply a fix at both start and end:

# Added fix to correct malformed JSON!
return json.loads(base64.b64decode(data).decode('utf8').replace('{[', '[').replace(']}', ']'))

in client.pi#435
To clean this up one could create a method to sanitize the raw json string before trying to json parse it
