Hi HansieNL,
I deleted again all the cache + cookies on my ipad, and I just tried a basic config.js and custom.js, with only the ip of my domoticz + user/pass, and same bad behaviour: dashboard still not loading on my ipad.
PS: my config is working on my computer with the beta+master versions ...

Looks like a python error in your code at line 341 or 342, the TabError. Python uses indentation which can be tabs or spaces and should be the same in the lines of the code. What did you use to get the indentation?

In plugin.py each indent is 4 spaces, so for this new line it should be 8 spaces ...

I have made a script to control my Yamaha CRX N560D radio which might be useful for others. This radio does not feature the Musiccast protocol but can be controlled over ethernet by http post. For FHEM a Perl module is available with all the commands and status requests. https://github.com/mhop/fhem ...
