Can anyone let me know how to resolve this?

I have the problem with the dashboards, if a client enters via the web, I want one of the dashboards to be opened directly, I configure this as the default dashboard in the client, but in the app, I do not want this to happen, I want them to appear dashboard icons, but if I apply a default panel to the client, this does not happen. Any idea?

Thanks!

Good morning, as of the thingsboard.cloud update to version 3.6, you can enter but the panel keeps loading and never starts. Why is that?

I am trying log in into mobile app but after building app when I tried to run app, app is just loading and not moving in into login page.If it goes to the login page it is not going logging in even after given correct username and password. If I give wrong username or password , it shows username or password is incorrect.

Thingboard Version 3.4.4 CE
Browser: Chrome or Firefox Latest
APP IDE: Android Studio

The feature can be to notify the customers when the alarm is created in the thingsboard's dashboard. The notification could appear in the notification panel.
I would like to know if it can be done individually.

I tried changing the images in the assets. also the checksum but for some reason I still see the old icons. Can anyone help me out with this issue or has anyone managed to fix this yet

My TB version is 3.3.4-SNAPSHOT. Which commit version should I use for flutter_thingsboard_ app？ In addition, Which version should I use for the thingsboard _client in pubspec.yaml? Thank you very much!

As above pic, I don't want to show ALL device profile to customer user. If admin didn't assign device to user, I think should hide device profile.

Good afternoon. I've been having this problem for a while now and I'm cloning the latest version of the app. Does anyone know how I can fix it? Thank you

Hi,

I'm wondering if you're aware of any open source library/service that would track Android's GPS location 24/7 and send it to ThingsBoard?

Also if I were to implement such such service would it fit into this app? But I'm really hoping something like that already exists because I think it's very useful and common use case. Currently we can get such solution from Google https://www.google.com/maps/timeline but I would rather own data myself in my own infrastructure.

Hello, thank you very much for this wonderful App.
I need users to be able to change the deviceName of each of their devices.
Since I did not find a way to set the value of the "Name" or "Label" property of the devices from the dashboard. I save it in a shared attribute (so that the device can read it and show it on its screen) that the user can change it from the dashboard.

I plan to retrieve the value with the following call

var entityId = EntityId.fromTypeAndUuid (EntityType.DEVICE, device.entityId.id!);
var deviceServerAtts = tbClient.getAttributeService (). getAttributesByScope (entityId, "SHARED_SCOPE", ["config.deviceName"]);

The problem is that I don't know where to replace "Name" of the device with the value of the shared attribute "config.deviceName" in the whole App.

Can someone guide me?
Thank you

Hello:
I have translated all the texts of the App into Spanish, but there is a message that is still in English and I cannot find where it is defined.

Does anyone know where it is?

I'm trying to run the ThingsBoard Flutter mobile app (on first run without any changes in the codebase), but I'm running into an issue:

Xcode build done.                                            6.6s

Failed to build iOS app

Could not build the precompiled application for the device.

Error (Xcode): lib/core/context/tb_context.dart:53:14: Error: Too many

positional arguments: 1 allowed, but 3 found.




Error launching application on DEVICE_NAME.

the app keeps loading like this as shown below when I tried to open the dashboard

the error on console shows , this is only some part , I cannot show all due to the error keeps adding up indefinitely

what happened ? I believe before this I'm using demo endpoint it works fine but now its not , is is related to the current thingsboard version which has been updated recently ?

Hello,

The first time I run the application in the simulator, it gets stuck in the initial screen, in order to continue I have to stop the simulation and restart the application, in this case, I access the login screen and I can enter the credentials, but it gets stuck again, it is in the third run when I can actually enter the dashboard.

thingsboard: 3.3.4

Hello every body,

i tried to build web app by this mobile application,
dashboards load in android but don't load in web app!
in dashboard just write: Not implemented!

do you know any solutions? (I tried with version 3.61 and 3.6.2 CE. and mobile app version 1.0.6 and 1.0.8 and result was the same like below image)

Hi,

I'm testing thingsboard mobile app with demo.thingsboard.io, I get "Not implemented!" message when I open any dashboard.
So, I cannot see any widgets.

Have you faced a similar problem, how can I solve this issue?

Thanks.

Hi every one
I try to get the originator of the notification. When I print ('[WebSocket Data]: Received notification: ${notification.notifications}');
I can see the originator. But when I try to access it by ‘notification.notifications?.first’. , I can't get any originator suggestions but other parts exist.
This problem is shown at below :

Please guide me on how I can access to originator of notification.

Hi!
After creating mobile app with Flutter and thingsboard, On the android 11 emulator, I obtained the login/password page.
I put my credentials for thingsboard.cloud and get... nothing.
The debug put no error messages.
I case I put wrong credentials, I got an error message.

Why can I access to my dashboards defined on thingsboard.cloud ?

Thanks!

Hi everyone,
Is there anyone hitting a strange problem as below?
I tried it in Samsung phone. Android 10.
The email and password textboxes are invisible.

When I touch the screen, the boxes appear.
I can key in but the words are not displayed too.
However, I can still login.

Updated: This issue happened when I set my phone into Dark mode. Normal mode shows OK. Should fix anything for Darkmode?

Like e.g. what is the minimal Android version that you need to run the app?

We need the requirements so the customer can prepare their mobile devices.

Thanks.

When I launch the app and enter the landing page, how do I set my server address

I´ve a bug in the iPhone App (Demo App with Demo Thingsboard).
Newest iOS 15.3

The Refresh button "Aktualisieren" remains greyed out, the only thing I can do is cancel.

Hey, first i have changed the url to my own server and then I logging it gets authenticated but suddenly it gets logged out and back to the login page.

Hey guys,

I've followed all the steps from the setup tutorial (https://thingsboard.io/docs/pe/mobile/getting-started/) accurately. If I set the endpoint to the ThingsBoard cloud (https://thingsboard.cloud) then the app works perfectly, but if I set the endpoint to my ThingsBoard PE server instance, then I can't login to the app. On the server, it does indicate a successful login however nothing changes on the app. Has anyone experienced this problem or could they advise on a solution? Thanks

I'm trying the flutter run command but it's giving me this error, I don't know how to solve it...

Complete bash error -> https://pastebin.com/wXWkS8dR

When I login flutter app, Exception occurs below Screenshot

Please fix it...

ThingsBoard Version: 3.2.2
android 11 API 30

I paste screenshot debugging

I want to create own app but i want to stylize design of dashboard by my self. How can i do it?

I want run this app,and first I execute pod install ,but it gave an error,like this:

Dear maker
I found the generic app to access to demo dashboard.
But why is there not an app for cloud dashboard?
Have to put flutter dart Android studio avdtools...
I used one day and at the end the login does... Nothing.

Could anyone exclaim me why I can't find a generic app for cloud thingsboard version?
Thanks!

I have been trying to connect to the thingsboard.cloud (the same thing happens if I try to connect to the demo) but when I try to log in using my username and password it shows the logo like if it was loading but then it stays in this same login screen.

The debug console shows the following output.

When I retry to log it just appears this in the output console.

We are using a self hosted ThingsBoard and the mobile app works fine with that, but we also wanted to use ThingsBoard Cloud so I would like to figure out what could be happening. I have checked that this issue appears both in Chrome and in my phone.
What could be causing this issue? Or which troubleshooting steps could I follow?
Thanks!

Going to:
https://demo.thingsboard.io
allows me to login and the app works fine

Going to:
https://thingsboard.cloud
allows me to type in my credentials but when I press enter it doesnt actually log me in, it just loads and goes back to the login page with no error message

Going to:
https://cloud.trumeter.com (my thingsboard site)
doesnt even load the login page just stays with the loading icon forever...

I assume this is something to do with thingsboard versions?

Using the latest version, 1.0.8, if the account you sign into on a iOS device has a selected home dashboard under account the the page loads forever on first login like this:

I have tested this on my own server as well as my own app, then I have tried a clean version of the app from this repo following this guide: https://thingsboard.io/docs/mobile/getting-started/
I have tried my own server as well as demo.thingsboard.io but non of them work if I have a selected home dashboard.

We are planning to use ThingsBoard’s open-source mobile application, to get the notification for the alarms and to view dashboards on the mobile devices.

I have installed all the packages and software required for the TB flutter app to run on windows system, but the errors attached below got raised whenever I tried to run the app from VS code.
Please investigate this and help us in resolving this issue.

After successful login returns to login screen.
The console keeps showing message: E/FrameEvents(28003): updateAcquireFence: Did not find frame.

If a user enables 2FA, login is impossible.

The user enters the correct credentials, but when they tap "Log In" nothing happens.
