Connection problem

[mat-l]

Thanks a lot for developing this integration which I am looking for since a while.

I have connected my BWT Perla Home to Wifi and tested the login-code in the VNC client and logging in works fine. Data is als send via Wifi to their severs and is visible in their app.

Unfortunately, if I would like to connect to Perla Home with your integration from Homeassistant I am getting a "connection problem" message, but no entries in the logs.

Any idea what is going wrong?

Can you enable the debug logging for the integration: https://www.home-assistant.io/docs/configuration/troubleshooting/#enabling-debug-logging Afterwards it should print something to the logs to give us a better hint what is going on.

[mat-l]

Unfortunately I cannot activate debug logging as the integration does not yet appear in the "devices & services" place as the configuration fails beforehand. Is there any other way to activate logging?

[dkarv]

I think you can go to http:///config/integrations/integration/bwt_perla and enable it there

[mat-l]

Hmm, a bit closer, but sadly it just shows a link to documentation and to known issues, but no possibility to enable debugging.

[dkarv]

I pushed a new version now with more logging. It should show an error now in the logs, even without debugging enabled. Please update and try again.

All right, thanks. Here you go:

As a side note: if I open the IP address of the device, e.g. 192.168.178.62 then in the browser I get forwarded to http://192.168.178.62:6080/vnc.html?resize=scale&autoconnect=true&show_dot=true

After some while, not on mobile, the browser based login appears, where I entered the login-code, which worked.

Can you check your firmware version and if the local API is enabled? You need at least firmware 2.02xx which adds the local API.

Then activate it in Einstellungen > Verbindung > API If you open 192.168.178.62:8080 in the browser it should display Not Found.

If all of this works, there is a connection issue between HA and your Bwt device. You could try to ping or access it somehow from within HA to see if this works.

[mat-l]

Oh man - I am sorry I missread the firmware version. I have 2.0018 and thought I just need 2.x Will wait a few weeks until I get the update (hopefully it arrives soon) and will then recheck your integration. Thanks a lot for your help.

[dkarv]

No problem! To get the update, you can contact the customer service. I don't want to put the email here, but another user recently was successful with this one: https://community.home-assistant.io/t/bwt-best-water-tech-nology-support/270745/118 Just add your serial number and they will push it to your device. It seems this version is still not officially rolled out.
