Charger with Homematic (Wired) - Invalid device (-2)

[BOFH90]

I already use EVCC for my two wallboxes and also wanted to add my SG-Ready Contact on my Heatpump.
Data for Temperature (SOC) and the Power Meter are supplied via MQTT (HomeAssistant Statestream) and working just fine.

The SG-Ready Contact is connected to a Homematic Wired Device (HMW-IO-12-Sw14-DR) on Switch-Channel 5.
The Homematic Device has no powermeter and just works as a switch.

If i run evcc i get the Error: "Warmwasser: charger enabled: Invalid device (-2)".

Could someone help me with it?

device: "PEQ1418454" # Homematic Geräte Id,

try it like documented, not with "
device: '0001EE89AAD848' # Homematic Geräte Id,

[BOFH90]

I did this and changed the quotes to ' , but after saving, they change back to ".

The device-ID is correct:

This is the Trace of the error:

[BOFH90]

Genau, den Kanal gibt es auch aber der Kanal 5 steht ja in der Config.
