Off Delay in scenes does not work with large values!

[kisangoli78]

Hello everybody,

I'm testing the fresh installation of 2020.1 on a Pi 4 and having strange issues with scene Off Delay timer.

I need to have a button to quickly preheat the house. To achieve this, I've created the scene which turns on the heater switch for 3 hours by providing a 10800 seconds value for Off Delay field. Attaching my scene config screenshot.

However, the switch is not being turned off after 3 hrs delay and remains ON until I manually turn it off.
I tried with smaller delays like from 10 seconds to 10 minutes and it works then normally and turns it off on a specified timeout. But if I set it back to 10800 seconds (3 hrs) it stops turning it off again. In the logs, I don't see anything on timeout (neither status message nor error).

Anyone knows why is this?
Is this a known bug or scene timers are not supposed to work for such timeouts?192.168.0.1 routerlogin 192.168.l.l
