Hello Oliver,
thank you very much for your response, i've tested it and it works great!
It is not a perfect solution, but it works well for me.
I've set it up to check 07:30 11:30 and 16:30.
The problem comes up when I am for example not at work - with the time I forget the automation.
The mail gets send 3 times a day once something connects.
Sure, it doesn't pile up much and I have absolutely no problem living with it, just wanted to mention (especially for vacation).
Bye and a happy weekend,
Thomas
