I’m able to enter with my credential but when I read the data the value is 01/01/2015, very old! This is very strange because when I use chrome to copy selector I see the correct data! How can I insert the actual data before scraping the data from website? Thank you

Hi, I need to scrape 4 data energy. One for example is the energy of solar panel that have this selector: #pSolareMon Now I see 600W inside website but I read 0.0kW using scraping. Very strange! For this reason I try to scrape other variable not necessary, for example the date and I noticed that was different! Inside website is present a box to choose the date and probably is necessary set the date before scrape. Boooo!
I "think" you will only see that the entity is unavailable. So, you can create an automation that triggers on the state "unavailable" for that entity and send you a message maybe?
Hi@@SmartHomeJunkie, I'm also busy with this, but I have 1 issue here. To see/ scrape our Engie dynamic energy prices, we need to login via our personal Engie account, and here we have already the first problem, they are using CAPTCHA in the backend of the login process. And till now, I'm not able to use Multiscrape for this, because, correct me if I'm wrong, it is not possible with Multiscrape?
What does the scraper put into the entities when the web page changes? Assuming it doesn’t just find something weird, but doesn’t find anything any more? Does it just keep the existing stale data or more usefully some kind of error message?
It depends if the structure of the webpage is still the same. In that case other "false" data will be shown. If the structure changed, then it will probably show either unknown or unavailable.
Can not get this to work at all, it always unavaiable. nothing works tried so many ways. Like copying the entire css selector path and all. While scraping with home automation integrator works flawlessly .
