How to use SmartGrid mode with Panasonic Aquarea L

[andiwirs]

Hello everyone,

I am using a 7 kW Panasonic Aquarea L-Generation heat pump and would like to know how to utilize the SmartGrid (SG-Ready) mode.

I have installed the addititonal board CZ-NS5P and set SG setting in the installers menu, but haven't wired anything related to the SG-Ready signal yet. I have already tried to enabled the emulation of the additional board in HeishaMon, and I can also see the SmartGrid entity in Home Assistant. However, changing the settings or modifying the SmartGrid entity there doesn't seem to have any impact on the heat pump's behavior.

My goal is to simulate the SG-Ready input to increase the heat pump's output when there is a PV surplus, allowing me to regulate it based on PV generation using the SG-Ready signal.

Could you please provide guidance on how to properly set this up?

Thank you for your support!
