Sonoff 433Mhz scenes + timer

A) Is it possible to add a timer to a scene? In other words, when my PIR activates a light due to movement, can I have it switch off again? B) Is it possible to add a schedule within the trigger can occur? In other words, the PIR only activates the scene between 19.00 and 6.00 when it's dark. Currently, moment anytime activates a light

I'm trying to make a rudimentary hot tub controller. I'd like to schedule a normal heating scene and a low heat scene to run at different times of day. 

Also, the ability to disable/enable a scene so if i wanted to use the hot tub during the low heat cycle i can override it.

I was looking in the same before buying. In the app there seems to be no option to activate a timer when pressing a button or after PIR detection. There seems to be only one device that can work with timers and pir. The sonoff 4ch pro. But that isn't a device you normally use as wall switch in your living room, toilet, e.d. Even in the garden you want some lights to be on until turned off and others with timer. This device can only handle the one or the other. :( So I am not buying a T1 wall switch, pir and bridge at the moment. It doesn't has the functionality I wished. Not even for the garden.

Exactly what I want, too. Looking forward for a solution. Ambient light sensor would also be nice, and possibility to combine trigger conditions (AND/OR etc.) in software. Turn light on IF sensor movement AND time is in range OR it's dark... turn light off after 10 minutes from last detection... instead of the ambient light sensor, an astronomical clock would probably be sufficient, too (but sunrise and sunset times differ greatly on different areas, in my country the difference is several hours between the north and south in the winter, so you would need latitude, longitude and time zone to make it work).
