Connect Trendz to the ThingsBoard

Trendz with ThingsBoard 4.2.1 or Older

This guide explains how to connect Trendz with ThingsBoard 4.2.1 or older. We strongly recommend updating ThingsBoard to the latest version to access all Trendz and ThingsBoard features.

To install Trendz for ThingsBoard 4.2.1 or older:

  1. Start from step 1 of the installation guide.
  2. Before the Start Trendz service step, configure TRENDZ_LICENSE_SECRET and TB_API_URL.
  3. Complete all other steps, except for Sync ThingsBoard With Trendz.
  4. Perform post-installation steps.

Configure License Secret

To interact with ThingsBoard 4.2.1 or older, you need a Trendz license secret key. If you do not have one, obtain it from the ThingsBoard support team.

Edit the Trendz configuration file:

1

sudo nano /etc/trendz/conf/trendz.conf

Add the following line and replace YOUR_LICENSE_SECRET_HERE with your license key:

1

export TRENDZ_LICENSE_SECRET=YOUR_LICENSE_SECRET_HERE

For Docker installations, update the TRENDZ_LICENSE_SECRET environment variable with the correct value.

Configure TB_API_URL

By default, Trendz assumes ThingsBoard is hosted on the same instance and accessible at:

1

http://localhost:9090

If ThingsBoard is hosted on a different instance or port, update the configuration accordingly:

1

sudo nano /usr/share/trendz/conf/trendz.conf

Set the correct URL:

1

export TB_API_URL=http://localhost:9090

For Docker installations, update the TB_API_URL environment variable with the correct value.
