Stromausfall, v5 Adapter, hwc OperatingMode ERR: SYN received

[cnu80]

Hallo, ich betreibe den v5 Adapter an einer Vaillant Wärmepumpe. Das Ganze ist via WIFI mit MQTT an HA angebunden. Funktionierte seit mehreren Wochen ganz gut.

Nach einem Stromausfall funktionierte der Adapter nicht mehr richtig. Bei einem:

ebusctl w -c hwc OperatingMode auto

kommt nur

ERR: SYN received

zurück. Vorher ging es ohne Probleme. (ebusctl w -c mc OperatingMode auto, funktioniert wie gehabt.)

Einmaliges Warmwasser funktioniert (zum Glück) noch.

ebusctl w -c hwc load on
done

Aber wie bekomme ich mein OperatingMode für hwc zurück? Wo fange ich mit der Fehlersuche an?

Ein paar Daten:

ebusctl

ebusctl find r | grep OperatingMode
hwc OperatingMode = no data stored
mc OperatingMode = on

Danke

[john30]

try to grab the sent/received bytes using a raw bytes log (ebusctl raw bytes), then I can check what's going on

[cnu80]

I updated to the newest firmware and after one day I have again connection problems. I saved the output with raw bytes. forgithub.log

thank you for your time.

[john30]

thanks for the log. it reveals delays of 40ms and more and this is way too much for eBUS protocol. anyway, please update ebusd to the newest version and check if that helps

[john30]

you might want to try the newest version just released as there were tons of commits related to wifi in ESP-IDF again

[cnu80]

Thanks for the info. I tried it out and it is working. !!
