Hello
I made a simple interface to my heat pump from Picco. The heat pump uses a controller from KEBA and I expect the interface to work for all KEBA heat pumps.

I have not seen an interface for HA, so I thought I should share it.
The communication is done via Modbus/TCP to the AP440 control unit, and no setup is needed in the heat pump except from establishing a connection to my local router.
Since Modbus/TCP is an integrated part of Home Assistant all setup was done in the configuration.yaml file. The configuration is shown below.
