Home assistant loses connection with EBUS adapter

[etmnidj1]

Hi Daniel,

I managed to install the EBUS to WiFi adapter module v6.1 into my vaillant geotherm heatpump.

I use HomeAssistant as a dashboard to monitor the heatpump. After setup everything works fine but I notice that after two to three days the connection is lost (both local IP address and in home assisitant ) with the ebus adapter module.

Wifi coverage is excellent nearthe pump so that shouldn't be a prblem.

Any suggestions what I can do?

Please let me know how I can provide you with logs etc.

Regards

Niels

Hi @etmnidj1 ,

does the adapter completely looses WiFi connection? Can you ping it?

Can you try to power it from an external adapter if the problem persists?

If I power it from an external adapter; do I need to change something to the adapter or just plug in an usb c cable connected to an adapter

remove jumper

[etmnidj1]

Ok how do I do that?

[danielkucera]

catch it with pliers or tweezers and pull it up

I meant where is the jumper on the board??

[etmnidj1]

I see a D9 but not d4 as it says in the documentation

Jusr removed a jumper and connected a usb-c cable to the board. The data is available again, see how long it will stay up now.

Thanks for the support
