OK. Made some changes to add system disable button.
To disable the system you have to define number of days to disable (a slider on V33) ,
and press the disable button (V32).
If you set V33 to 1 the system will disable until midnight if you set it to 2 the system will disable until tomorrow midnight …
When pressing the disable button all switches are turned off.
The disable date will be presented on V32 button.
Again this is not fully tested (each iteration is several days to test) so please let me know if you find bugs.
enjoy.
