marq24 / ha-waterkotte Goto Github PK

Hi.

it is not possible to add Watterkote heat pump because the integration after update doesn't ask to input user and PW:

The user and PW are hard coded in source code with the comment that this is really true - waterkotte have ONLY hardcoded user credentials!:

• https://github.com/marq24/ha-waterkotte/blob/main/custom_components/waterkotte_heatpump/pywaterkotte_ha/__init__.py#L140C1-L142C1

        # this is really true - waterkotte have ONLY hardcoded user credentials!
        args = {"username": "waterkotte", "password": "waterkotte"}

Unfortunately this is not true, on my Watterkote heat pump is possible to change the PW, so I'm not using the default PW:

Menu -> Service -> System control -> User account

Workaround:

• Change the PW in the file mentioned above and restart HA.

Thank you for reading !! ;-)

Hello Marq, first of all thank you for your great commitment, your Ha extensions are very useful. I have a question about the Waterkotter addon. Would it be possible to query several heat pumps at the same time via your extension? I have 8 Waterkotte heat pumps in an apartment building and am currently monitoring them via the iobroker and then using mqtt on ha. I would be grateful for an answer.

Hallo Marq, erstmal Danke für dein super Engagement, deine Ha Erweiterungen sind sehr nützlich. Zum Waterkotter Addon habe ich eine frage, wäre es möglich mehrere Wärmepumpen zeitgleich über deine Erweiterung abzufragen? Ich habe 8 Wärmepumpen von Waterkotte in einem Mehrfamilienhaus und überwache sie momentan über den iobroker und dann mittels mqtt an ha. Für einen Antwort wäre ich dir dankbar.

When I try to start the integration, upon entering the IP where I access the EasyCon web (192.168.1.52), I instantly get the error “Host/IP or the Password is wrong - could not reach system”. I have waited a day without accessing the Waterkotte web or app to close the active sessions. My username and password are Waterkotte. As information, my heatpump has a remotebox at IP 192.168.1.53 which cannot be accessed via browser.

Watterkotte Ai1 GEO 5010.5
Hot water setting 45°C
Setpoint switching difference 5 K
If the hot water temperature falls to 39.9 °C, the heat pump starts to heat the water back up to 45 °C.
everything works well so far.
However, as soon as I use the integration for a few days to control the hot water according to the available energy from the photovoltaic system, the watekotte no longer reacts correctly.
I have already had cases where the required hot water temperature is 45 degrees. we use water and then the sensor shows 30 degrees but the waterkotte does not start even though the switching differential is 5 K.
The heating only produces hot water again when, for example, I increase the hot water temperature extremely, for example 60 degrees or when I restart the heating, then it recognizes that the water is only at 30 degrees and starts the hot water preparation again.
It seems as if the control system would get confused over time.

Hi and thanks again for your continuous work on this integration!

With the new version came a feature „'Warmwasser Disinfections-Anpassungen' verwenden“. Can you elaborate what this feature does and how I could activate this on an already running integration? The option is only visible for a new configuration.

Thanks!

Dear Matthias,
I was wondering if you had any interest or ideas on how to implement this here.
Do you have documentation on this?
There are a lot of records...

A little bit spontaneously I have decided to declare the fork-version of the Waterkotte integration as deprecated - after the refactoring the integration does not have much in common with the origin (the source of the work).

The only way to disconnect a repository from it's fork is by starting with a complete new repository - which I just did - so the "previous" version is still available here: https://github.com/marq24/ha-waterkotte-the-fork - but there is so simple way to move the issues / stars and follows over to the new repository.

Please don't hesitate to just start them again...

Hello,

as using a DeltaT for Source-pump control in cooling-mode tends to hit the "min allowed temp"-alert for source-in-temp at the beginning of the sommer.

Thats the reason why I run the "target temperature"-mode for the source-pump in cooling mode.

It would be nice to be able to set the "target source-in temp." dynamically based on the current dewpoint to avoid having any water dripping on the pipes :)

According to the WebUI its:

http://waterkotte/cgi/writeTags?returnValue=true&n=1&t1=A1034&v1=181&_=1719582684952

Setting the value to 18.1*C

Thx a lot :)

Hello, if I want to register the Integration, the error message "expected str" appears immediately. What am I doing wrong?

Best regards
Frank

Since tonight my AlarmBits sensor is "unknown" and my log is getting filled with attached msg. Looks a bit like a var-type issue isnt it?

Hi,

from time to time, the time on my heat pump changes to a greater or lesser extent.
Is there a way to set the time (and date if that's possible) via Home Assistant? Then I could set up a daily automation that does exactly that and keeps the time up to date.

Thanks!
