The right Config for Altherma 3 H MT W

[jp3112]

I have now placed my ESP32 inside my indoor unit.

However, I'm receiving barely any values in HomeAssistant, and those that do appear are nonsense. In MQTT Explorer, I only see the following messages:

Time out! Check connection
Querying register 0xa1... 
Retrying...

For "Querying register 0xa1...", the values change (0xa1/0xa0/0x61/0x62, and various others).

I used this file for ESPAltherma:

def/German/Altherma(EPRA E ETV16-ETB16-ETVZ16 E_EJ series 8-12kW).h

And I have the following heat pumps:

• Indoor unit: ETBX12E9W
• Outdoor unit: EPRA10EW1

In HomeAssistant, under States, I only see the following:

friendly_name: AlthermaSensors
Maximale Anzahl - Inverterverdichter: 0
Maximale Anzahl – Standardverdichter: 0
Maximale Anzahl - Außengerätelüfter: 0
Max. Außengerät Leistung (kW): 0
WifiRSSI: "-78dBm"
FreeMem: "222664"

My def file looks like this:

What might be causing this? Is there an error in the configuration file?

Turns out I’m just to dull to read the wiring diagram.
I’ve overlooked, that the tx pin on the esp has to go into the rx pin on the heatpump.
I connected tx to tx and rx to rx.
