Hello everyone,
I would need a little help from automation experts. I am currently programming an automation for the hot water preparation of my heat pump. Here is the current state:
It checks if the feed-in power is > 3 kW for 5 minutes. If yes, the hot water one-time charge is activated if certain conditions are met.

I now want to adjust it so that the following is implemented:
1 Kelvin before the hot water target temperature is reached, it should be checked whether the PV generation power (not feed-in, because it is likely close to 0 due to hot water preparation) is still sufficiently high, and further conditions should be checked → What components do I need to use here?
If all conditions are met, the hot water target temperature should be reset (10 Kelvin higher than before) → This should be executed as a loop until either the conditions are no longer met or a maximum target temperature is reached (90 degrees).
Additionally, I need an abort condition: If the room temperatures fall below a certain threshold at any time during hot water preparation, it should be aborted.
Does anyone have an idea on how to best implement this?
Thank you in advance.
