Can't find my "home"

[JoaLage]

First of all – thanks for this scripts! I have used them to get weather data from our Netatmo stations to our web page.

Now, suddenly?, I get "Unfound home with ID 0" from

$_splNetatmo = new splNetatmoAPI("xx", "xx");
if (isset($_splNetatmo->error)) die($_splNetatmo->error);

If I use a specific home ID eg. 1, I still get "unfounded". There are two "homes" in our setup.

I guess something has changed on server side, but I can't find out what.
