@T_Ja I have tried the parent control functions further now. The internet access is stopped according to plan, but when bedtime is over, access is not set back on. I cannot achieve access again...

@David-TP I have not included any time limits, only the bedtime function. Removing the device seems to solve the problem. I will try to do some more tests as you suggest when I return home in about 2...

@INIMOD77 I have the same issue. Information regadring solution is highly appriciated.
