Hi.

Could you Check this please?

Maybe you could tell me, If I did interprete the CanApiJson VG - telegrams in a correct way?

My WTC-GB 25 B has no menu item "json", perhaps its one of the first versions from 2017?

Here is a kind of a checklist, you can try out:

Maybe your device has a complete different / new protocol?
-->interesting for a new research project. :)

Kann ich gerade nicht nachprüfen da ich keine Verbindung zur Heizung habe, aber du hast dir echt dieses sauteure WEM-Modbus Teil gekauft?

Yes, I have got this device:

More and more users are interested in smart home technology, even if it’s just to monitor the status of their heating system, inverter, battery storage, car charger, etc.
Until now, for Weishaupt WTC devices, you’ve always needed either the WEM portal (disadvantages: lack of real-time capability, time-limited paid license) or a Weishaupt protocol converter (very expensive: 700 to 800 euros).

By analyzing the protocol, you can now read and display the values directly (e.g. in Node-RED, Home Assistant, Windows/Linux/AmigaOS [curl])
-- without needing expensive protocol converters or WEM portal licences.

These things...:
WEM portal disadvantages(...),
expensive WEM-Modbus protocol converter

...were the reasons for the research and for analyzing the protocol:
