Use “Scrape” to read data from the web browser

Hello everyone,
I want to use “scrape” to read data from my heatpump web browser.
Unfortunately I don’t get any value.

It is also possible to log in without a password.
After logging in, I would like to read out the first temperature value.

Her is my code:
scrape:

The entity Vorlauf_1 is always unknown.

What am I doing wrong?
Thank you for your help

If you do View Source rather than use F12 DevTools, can you see that value in the HTML?

If not, it’s being dynamically fetched. Use the Network tab in DevTools to work out where it’s coming from.

Hi Troon,
thanks for the quick reply.
You’re right, it doesn’t show up under view-source.
How do I find this in DevTools?

Press f5 to reload. You should see a load of resources being loaded. Look at the ones of type xhr and see if you can find one where the response looks like it contains the data you need. I answered a very similar question here: follow the thread:

I could access the URL in that example, though, which I can’t with yours — you’ll have to work it out yourself. :slight_smile:

Thanks for the reply

After I pressed F5 the login window opened.
Here is the picture of it.

I don’t think I can find a solution on my own…

I would still be very happy about any further ideas :slightly_smiling_face:

Ok now log in to that window…

After logging in, the DevTool closes.

When I open the DevTool again, the entries are empty.
