    Hi everyone, I am having a hard time filtering data on a TS chart. It doesn't matter which kind of combination or conditions I use all data is removed when the filter is applied.
    It seems simple, its a number type of value. I have tried to follow the "Advance Filtering" video tutorial but it does not work, even with the demo samples from thingsboard. Could someone give me a hand with that? Thanks!

    Hi all thingsboarders. Does anyone know if there is a size limit to Telemetry JSON kB ? We are tryng to save JSON via http Integration which is 280 kB but is seems the Data Converter isnt processing the msg payload.
    Hi thingsbord community, I need some help and guidance of how to retrieve the past telemetry data stored in things board cloud . I want to able to retrieve the last 7 days or last month data . I want to able to retrieve the data preferably from GUI itself , like from rule chain itself I need to retrieve it.

    @abhinav_singwal_twitter well I also need the answer . I wil share what I did , I used an aggregator stream and then used the sum aggregator function inside it and then also tweaked some other settings and it is working. But the problem in this approach is that you won't get the last 12 hrs every time. What it does is it will try to sum up the values that lie between an interval like 9 am to 8 pm . Then at 8 05 pm the output by the node will be reset to zero . Hope that helps you . 😇

    I have this SSL/certificate problem with HAProxy and Let's Encrypt, which is a bit challenging.
    The description comes right below:

    I've installed Thingsboard monolithic architectre with Docker on Ubuntu 20.04.
    Now, I wanted to enable https access using HAProxy and Let's Encrypt certificate, as instructed in the tutorial
    Everything goes well until this command: certbot-certonly --domain your_domain --email your_email
    that throughs the following error: (I changed my real domain for myservernameanddomain)

        Saving debug log to /var/log/letsencrypt/letsencrypt.log
        Plugins selected: Authenticator standalone, Installer None
        Obtaining a new certificate
        Performing the following challenges:
        http-01 challenge for myservernameanddomain
        Waiting for verification...
        Challenge failed for domain myservernameanddomain
        http-01 challenge for myservernameanddomain
        Cleaning up challenges
        Some challenges have failed.
         - The following errors were reported by the server:
           Domain: myservernameanddomain
           Type:   connection
           Detail: Fetching
           Timeout during connect (likely firewall problem)

    There is no issue with the firewall. In fact I disabled it to discard any problem related to it.
    I've also checked the access to the server and it has a type A DNS record, so its accesible via DNS. ( but it does not have AAAA record, which I believe is for ipv6, and can't tell if it is part of the problem)

    I would appreciate any help in solving this issue, as I believe it is important to enhance security.
    Thank you !!

    Hi All. Does anyone know what directory location would be best to save Js library on Thingsboard Server for use in custom widgets via Widget Resources ? We are using CDN at the moment but its not loading fast enough and thought it would be better to save the library on local TB server. Any advice gratefully welcome.

    theFool: Yeah, I find it, thanks for your help😁
    np, it's a great piece of software :)
