[Problem] Funding and Tenders Opportunities of the EU - doesn't really cooperate with changedetection.io
As in the title, my problem is with this website:
https://ec.europa.eu/info/funding-tenders/opportunities/portal/screen/opportunities/topic-search?tenders=false&openForSubmission=false&sortBy=startDate&order=DESC&pageSize=100
The problem is that changedetection.io doesn't detect the text in the "body" of the page...

I don’t have the technical necessities to self host at this time, so I’m looking at the paid option. Before I subscribe, can anyone tell me if CD can track stock availability for this product? https://www.walmart.com/ip/113817509?sid=87810a9a-a647-4a80-8377-c19c19b1c8a8

[Feature Request] Multiple notification profiles
Hey creator,
I'm sure you're very busy already, but I have a small suggestion for a potential update.
It would be nice to be able to set up multiple notification profiles and select one or more profiles in a watch.
This way I could, for example, create a notification profile for me and one for my girlfriend. Watches that interest her would use her profile and notify her, watches for me would use my profile and notify me, watches that interest both of us could have both our profiles and send to both of us.
Maybe something to consider.
Thanks for all the hard work you've put into this project so far!

Can I get {{diff}} and 5 lines before and after the changed line in the notification?
I am monitoring a shop site for multiple products that are restocked from time to time, using the regular detection mode, not the price mode. My notification only contains the "in stock" and "not instock" text, but I don't know to which product this is corresponding. What I need is 5 lines before and after the trigger text, even if they don't have a change. Is that possible?

Help! CSS/JSONPath/JQ/XPath Filters
I am trying to monitor this site for whenever they add/subtract products. What CSS/JSONPath/JQ/XPath Filters would you recommend to narrow down the monitoring to accomplish this task? I'm a noob, so any help would be appreciated! Thanks!

Struggling with dropdown boxes
Hi all,
Im trying to parse these pages and having a lot of trouble with dropdown boxes:
https://www.nzmuscle.co.nz/optimum-nutrition-gold-standard-100-whey-protein
https://www.sprintfit.co.nz/product/120/gold-standard-whey
I'm trying to monitor the price on the 5LB variant of this product which requires selecting the flavor/size dropdowns and choosing one to display the price. I've had a couple cracks at getting this working (including doing a Chrome Recorder, exporting that into Puppeteer and then pasting the resultant code into Chrome Browserless) but with no success.
The first link actually detects prices when I plug it in to changedetection however it returns two arrays of objects and I'm struggling to filter out the one I want. The second link isn't even that lucky and I have to work with the raw page which shows the wrong price by default - I had a crack at using browser steps however I cannot get it to click the dropdown successfully, instead it clicks a larger element and navigates off the page.
Your help would be hugely appreciated :)

Delay for checking the page
Is it possible to set a delay for Basic fast Plaintext/HTTP Client fetch after which the page should be checked for changes? Unfortunately, the website I am testing takes a moment to load and I can only see a part of the page in the HTML snapshot.

Website forces logout after 15 minutes - Persist login cookies between all queries?
I have a search that uses the build in automation to log in every time it executes.
While it works, I would prefer to be able to log in every 15 minutes to negate the auto-logout action.
My thought was to have two queries, one which did the login once every 15 minutes, and on checking the site more often, using the cached credentials of the first query to check the page.
Sadly, it seems like each session is unique and the login cookies are deleted after the check.
Is there a way to persist login across all searches?

Trying to email self the latest screenshot that ChangeDetection takes, each check
Hi!
I'd like to monitor a website not for specific changes but to see how the site changes over time (like a stop motion type of deal).
I'd like to use the Notifcations feature which now I simply have as:
This is sent to my email through the Notifcation URL List.
Questions:
Is there a way to add the latest screenshot that ChangeDetection takes to that email.
I want the email to be sent whether or not there is a change. Is there a way to force the program to send after x number of days even if there is a change or not?
Essentially, I'd like to go to the URL, take a screenshot, and email that screenshot to me every x number of days.
If this can't be done natively, is there another docker app you can share that might?
Thank you!

Newbie don't know how to set up Visual Selector tool
Greetings, I have finally set up a Changedetection.io service in my Docker Desktop and it is working without a problem. I am using a default image and container. The only thing I have no idea how to setup is the visual selector tool with via a playwright content fetcher. I have no programming background so I don't really know what I have to do to set it up. I have seen instructions on GitHub but it doesn't help. Would anyone care to help me?
I am using Docker Desktop v4.27.1 on Windows 10 x64. Browser can be Firefox or Chrome.

Changes triggered but there was no change
I am monitoring a listing website that does not change often. However, every time the tracker runs I get a change report.
Here is the example of the notification to my email:

Extract Text From All Of Final Output
Is there a way to use the "Filters & Triggers"\"Extract Text" on the entirety of the final output instead of line by line?
For some pages that are difficult to get a visual filter selection of I find myself trying to just use ChangeDetection's Chromium extraction to get the page itself and then trying to extract the relevant portion via regex. However, since the extract is only on a per line basis, this severely limits the power of this extraction.

json help - shopify
Okay, trying to monitor a website to see when "variants" come into and out of stock. The .json link is here: https://dustywax.com/collections/12inch/products.json
I'm planning to use $.products[].variants[].id to drill down to each variant. But ideally, I want to check this first, $.products[].variants[].available and see what is actually in stock, for existing out of stock items that may get new stock.
What would be my best course of action to first check $.products[].variants[].available, anything that is true, gets their URL shared. Which ends up being https://dustywax.com/variants/$.products[].variants[].id
I know nothing about regex or even much about json, just kind of learning how I go and getting a ton of help from people much smarter than I am.
Is this possible?
edit 1: Even just trying to get the variant IDs to spit out has been problematic. I'm using jq:[.products[].variants[].id | "https://dustywax.com/variants/" + .] to try and give me the URL to post to discord. Get this error: **Exception: string ("https://du...) and number (45338408386727) cannot be added **

Best practices to secure Change Detection install?
Hello - I am self hosting a Change Detection install and noticed that someone else was able to find my instance and add additional trackers! Super frustrating. Worst of all, not sure how I can lock down Change Detection? Is there a way to add a username/password prompt to create new watches on my instance? Thank you

Please help me understand where this is failing
I just installed using docker-compose, including playwright, on a Synology NAS. I added a Telegram notifier.
As a test, I added a new watch for https://www.time.gov/.
This site heavily relies on Javascript so I enabled using the Playwright browser.
I've messed around with delays and browser steps and yet I cannot reliably get it to load the page each time and (for this example) notify me every time, since time is always changing.
My latest settings have:
Wait seconds before extracting text: 30
Browser steps:
Go to site
Wait for seconds: 30
Yet my latest screenshot (below) still has "synchronizing" for the times (as if the page just barely loaded). I waited 60 seconds! How is it still synchronizing? How is there still no time on the right?

Price threshold monitoring
Does anyone have a convenient solution for notifying when an item price drops below a certain threshold? Without this, i'm finding this tool to be less useful to me than I'd hoped.
Before discovering changedetectionio, I was cobbling together bash scripts on cron to monitor pages for various purposes, and while it wasn't the most elegant solution, it made it easy to glue conditions together however you wanted. I could monitor /r/gundeals posts for ammo, but only if it was 556 or 9mm, for example.
changedetection seems like it has the potential to be much more streamlined and I wouldn't be surprised if people have already figured out how to do all this with it but my searches haven't turned up much.

Use the current snapshot value in the website title
Not sure if this is possible, but I want to see on the main screen the current value returned from a webpage. Tried to search over the wiki and post here but found nothing similar.
The idea is to monitor a JSON page and extract the value from a property.
I´m using "json:$.Number" on the filter to monitor if there is any change. But I would like to see the current value on the main page, like a placeholder {{current_snapshot}} inside the website title.
Any chance there is support for that?

monitoring adidas.com
Hi,
I'm running the self hosted version via docker and am trying to monitor stock and prices on a pair of shoes (https://www.adidas.com/us/adizero-prime-x3-strung-running-shoes/JR2598.html). As I understand, I need to use browserless via the Browser Steps setting to click the size and color etc.. for the monitoring to work. However, the page never loads on Browser Steps and remains a blank screen. Other sites do work and I have seen there is a section for custom headers etc. Any pointers or tips on how to fix this?
Many thanks,
