Heishamon Homeassistant with Multiple Heatpumps

Hi,

I am using: GitHub - kamaradclimber/heishamon-homeassistant: An integration for heatpumps handled by heishamon

I have added a second heatpump by changing the second topic prefix to panasonic_heat_pump2.
It´s working i got all entities. But now i have the problem that sometimes commands are not beeing send.

For example:

Right now i set Force DHW Mode. The switch jumps up. But after refresh its back down and state is not changed to dhw only.
Maybe 1h later i set Force DHW Mode and it works immediately.

Same think for other parameter like Aquarea Mode or heat request shift.

Sometimes the command works in real time and sometimes its not working at all.

Any idea where the problem could be?

Thanks a lot
