@gioe 6 So in the console you see various read data timeouts. This is an indication that the data cable is not (properly) connected. Please check the cable on both ends.

I think he meant the cable between the Panasonic and the HeishaMon
Sarcasm is my superpower! What's yours?
Could it be due to an incorrect installation of the Mosquitto MQTT broker installed on the PC where I see Heisha Monitor? If I interrupt the Mosquitto service, the data remains the same.
No, it's the connection between your heat pump and HeishaMon which is not working: heishaMon isn't communicating with your Panasonic HP.gioe 6 schreef op vrijdag 31 oktober 2025 @ 18:14:

@gioe 6 hoe heb je de kabel aangesloten op de warmtepomp? Maak daar eens een foto van.

Now I have a doubt: I connected the CN-CNT connector of the pump to the CZ-TAW connector of the Heishamon card.
Yes, the CZ-TAW on the Heishamon card is a proxy for the CZ-TAW (if you have it). You need to connect the heatpump to the connector labeled HEATPUMP.

Ik heb al jaren de kleine Heishamon en ga hem dit weekend vervangen voor de grote. Vandaag binnengekomen. Voor de kleine gebruikte ik een externe voeding, gewoon 5V DC, die door de muur naar een stopcontact in huis loopt en dus lastig is te vervangen. De grote Heishamon wil een USB-C-stekkertje. Kan ik een USB-C kabeltje kopen, het stekkertje afknippen, en die verbinden met het standaard 5V DC (rood/zwart) voedingskabeltje? Moet ik nog ergens op letten?

@RichieB, thank you very much for the connection suggestion. The CN_CNT connector has the following pinouts (from bottom to top):
1) + 5 V
2) 0-5V TX (from the heat pump)
3) 0-5V RX (to the heat pump)
4) +12V
5) GND
Please, do you have the pin-outs for the HEATPUMP connector on the Heishamon board?
(Is the pin at the bottom the GND?)
Thanks, Giorgio

@gioe 6 I just ordered the cable with the Heishamon and plugged it in. I don’t know the pin-outs.
