Hello,
I try to read into a IPX800v4 (this is a PLC for domotic application) with a WebClient fonction
I use as url http://192.168.0.250:50543/api/xdevices.json?key=XXX&Get=C
XXX is replace by the correct key for sure
The status code is 200, it should works correctly
But the result is '{' that's my problem
When I try the same url with a web browser the result is correct like
{
"product": "IPX800_V4",
"status": "Success",
"C1": 16,
"C2": 2,
"C3": 0,
"C4": 0,
"C5": 0,
"C6": 0,
"C7": 0,
"C8": 0,
"C9": 0,
"C10": 0,
"C11": 0,
"C12": 0,
"C13": 0,
"C14": 0,
"C15": 0,
"C16": 0
}

When i replace the url by a web site like google for exemple it works

Can you help me please ?

If I try http://192.168.0.250:50543/api/xdevices.json?key=XXX&SetC1=1 it write correctly
Why can I write but I can't read the Json ?
