I changed the <wizardDone> to 1 and Toon displays its dashboard now. So I do not need to fool the meter sensors anymore. Thanks!
Now can the "customize all the dashboard" begin

Another thing. Since I 'm not using the meter-adapter. Is there any way of suppressing the warning? I don't want it to be connected and send unnecessary radiation. When I had to adapter connected(which was done in the setup-wizard) there was no warning in the top notification bar when the dashboard was displayed. Even while it was not plugged in the power socket at the time. But once I removed it though software a red triangle popped up and does not go away.
As a side node:
I blocked Toon in my routers firewall and executed all the Disable Eneco stuff. But still I see that Toon tries to contact the internet(hits on the firewall rules). I don't know if this is normal behavior of the OS but maybe I can just firewall it inside Toon so my router will not get useless packets to block.
