Now, my water heated today, the shelly switched off, as I made no energy anymore, but 15 minutes later, it started again, as the higest peak from pv as still reached.

Now, how can I set a reminder, that the water still heated today?

Make a date helper and set it as part of your script.

Thanks for your reply. Could you give me an example, I didn’t use this helper up Till now.
