My swimming pool setup is as follows:

1. Sonoff Thr320d is used for measuring humidity and to turn on ventilator OUT
2. Sonoff Dualr3 is used to turn ventilator IN and to turn ventilator heater

When I set conditional scene to turn on all devices if humidity goes over 65% this works perfectly. The problem occurs when I want devices to work until they reach 55% or at least to work 10 minutes.  
This is not the case because all devices will turn off after 1% drop (64%).  
I would like for devices to work some time (for example 10 minutes) or conditional turn off for example when humidity reach 55%.

Is there possibility for this to work, thanks in advance.
