No data showing in HomeAssistent, errors in log #62

Hi, I want to connect my vaillant EcoTEC VCW346 (with VRC720) with my home assistant, but nothing seems to work. I use this adapter: https://lectronz.com/products/ebus-to-wifi-adapter-module (I have version 5.1), and I succesfully upgraded the firmware to version 6.1. I tried several times to re-calibrate the variable resistor, that seems OK. Every time I get the error "received unknown MS cmd: ...." or something like this (see attached logs) What can cause this error? Notice that the adapter is powered by the eBUS. Kind regards and many thanks for any help on this issue!

Did you try back to switch to an older version of FW?

You can also try to use port 3333` without enhanced protocol support.

BTW, what is your wifi signal on the adapter?

Also to me this seems like a weak signal (messages are late). Can you check the output of status server? telnet esp-ebus.local 5555

Hi, I first tried with an older firmware and I had the issues. Now with this firmware, the issue persists. The WiFi-signal is 3 bars on the internal webpage of the device. (It is only a few meters between the device and the router).

-61 dBm is quite good. Can you please try the latest version v7.0 ?
