just tested on mine,  adult no restrictions, child bedtime in 5 mins time. 

come that time, tested on all and all worked as expected.  non registered devices worked ok too. 

firmware is 1.2.4 too

Thank you thefunkygibbon!

I don't suppose you have enough devices lying around to test with more profiles and more devices... then let it run for a few days? 

In the case in question, we don't think it happened immediately.  It's almost like a leak... it works well blocking and unblocking things initially, then after a few cycles (a few days in our case), we think it started to just block everything after the first profile's bed time.

Really appreciate your help.

well i've had it set up in a similar way tbh for a few weeks.  child account bedtime 11pm , an adult account with no bedtime.  and my devices which are not associated with an account.   

never had it happen before to me :( 

weird. 

That really does add to the wierdness.  I've set up dozens of Deco meshes in various houses and haven't come across this before, so I assumed it was a 1.2.4 thing. 

Thanks ever so much for taking the time to reply though!

thats ok.  wish these forums were more alive :-( 

When it comes to that Adult devices go offline at bedtime set in Pre-teen profile, please try to add a new unassigned device into the Adult profile, then check if the newly added device will go offline or not.

Also we recommend to delete the current Adult profile, then create a new one and check if the issue persists in this case.
