[Issue]: Circulating power consumption without heating demand

[turbolooser]

I am see a weird power consumption on my daikin equipment when using this Integration vs the Daikin app.

My equipment

1. DAIKIN Perfera Wandgerät FTXM20R 2,0 kW
2. DAIKIN Perfera Wandgerät FTXM20R 2,0 kW
3. DAIKIN Perfera Wandgerät FTXM25R 2,5 kW
4. DAIKIN Multisplit Außengerät 3MXM40A 4,0 kW

When running 1 internal unit (just as example unit 2) in this case) I do see this oscillating power consumption although there is no heating demand.
target temp: 18.5 C
current temp > 21 C

power consumption:

current inside temp:

Time windows between 18:00 (6 pm) and 21:00 (9 pm) is being set by this Integration. As you can see power consumption goes up and down for no obvious reason as there is no heating demand and no other unit is enabled.

Starting 21:00 (9 pm) I have disabled any settings from this integration but enabled the daikin app including a timing program. Since then there is no oscillating power consumption anymore.

Would anyone have an idea on this weird behaviour?
Coould anyone confirm the same or has a different experience?

I have no idea
