Following the update of the Wattsense product catalog in October 2025, we have decided to migrate licenses created before October 1, 2025, to a corresponding license in the new catalog.
This migration will be to your advantage. Here are the details:
For Bridge licenses: switch to the new default multi-protocol Bridge license with 100 points or Bridge 5000 points, without any additional fees, depending on the number of points currently activated on your box.
For Tower and Tower Control licenses: switch to the new default multi-protocol Tower Control license, which includes schedules for controlling setpoints and automation scenarios with 50, 100, 200, 500, 1000, 2000, and 5000 points, without any additional fees, depending on the number of points currently activated on your box.
If it has been activated, the license activation date will remain the same, as will its expiration date.
Examples:
You have a Tower Medium with 200 points included and 2 extensions of 50 points. The license is valid for 3 years and was activated on October 4, 2024 (expiration date October 4, 2027) => you will switch to a Tower Control 500 points license with the same activation date of October 4, 2024 and an expiration date of October 4, 2027.
You have an IoT Bridge with 100 data points with only the LoRaWAN protocol authorized for incoming data. The Bridge was activated on June 20, 2023 (cellular communications included for 10 years) => you will switch to a 100 points multi-protocol Bridge license. The activation date remains June 20, 2023, and cellular communications support will end on June 20, 2033.
The migration will happen on June 30th and will not require any action on your end. You will be notified by e-mail. Once it is complete, you will see the names of the new licenses appear in your box information.
Changes to how virtual properties are counted
Virtual properties are points available exclusively in the cloud that you can create in the console based on the values of incoming properties. There are of two types: consumption calculation and arithmetic calculation.
Until now, virtual properties could be created up to a limit of 10% of the points included in your subscription. Example: for a Tower license with 100 points, a user could create up to 10 virtual properties in addition to retrieving the values of 100 properties.
Soon, and on the same date as for licenses—June 30, 2026—the limit on the number of points in your subscription will apply to incoming properties and virtual properties, eliminating the 10% credit. Example: For a Tower license with 100 points, a user will be able to create as many virtual properties as they wish, as long as the total number of incoming points and virtual properties is less than or equal to 100.
Following this update, a single counter will then be visible in your box’s information:
This article explains what happens when your Tower license expires. Bridges are also impacted by this process even if they are not directly linked to a license.
Towers
One month before a license expires, emails are sent to the Tower sub-organization administrator and billing contact. They indicate that the subscription is about to expire and suggests taking action to renew the license. Other reminder emails are sent one week before the expiration date and on the expiration date.
At the same time, this information is also displayed on the console interface :
1 month before the end of the license
License has expired
If you click on the Renew shortcut, you will have access to a list of technical impacts if the licence is not renewed detailed here:
To renew the subscription attached to your Tower, please contact your reseller.
There is currently no ongoing subscription, so the features of your Tower are restricted.
What happens if the subscription is not renewed?
Interruption of cellular connection between your box and our servers
Stop remote box configuration
Stop sending data from the box to our servers
Automatic updates of the box firmware: possible if the box is connected to an open Ethernet/IP network
No impact on redirects and other local operations. The device will continue to behave the same locally. Values will be redirected between equipment and gateway.
How to retrieve your data?
Use the Archive feature or the API. Your data will be deleted for good after 6 months after the end of your subscription.
The admin(s) of the organization of your device were notified by email.
Note: if you have already renewed, this message will disappear on the start date of the new subscription.
The following diagram shows the features that are no longer available as well as the services that are still active after the license expires.
Legend
Services are interrupted
Services are available for 6 months (archive API feature)
Six months after the last license end date is reached, the box data is deleted from Wattsense servers. All the data is deleted but not the configuration. Users are notified via email and in the console.
A final email is sent when the tower goes into restricted mode. At this time, the status of the box changes to gray in the console.
Bridges
Bridges do not have a license strictly speaking, but there is a 10-year limitation linked to the GSM subscription. If you do not use the GSM connection (your bridge is connected via LAN / Ethernet network), there is no impact.
If you use the default GSM connection :
If the subscription is not renewed when the 10 years period is reached, the features of the Bridge will be restricted as described in the console :
SIM card renewal
Your Bridge is equiped with a SIM card with data valid by default for 10 years. It enables a cellular connection to our servers. To renew your SIM card, please contact your reseller.
If your SIM card expires, the features of your bridge will be restricted.
What happens if the subscription is not renewed?
Interruption of cellular connection between your box and our servers
Remote configuration of the box: possible if the box is connected to an open Ethernet/IP network
Sending data from the box to our servers: possible on a one-hour slot if the box is connected to an open Ethernet/IP network
Automatic updates of the box firmware: possible if the box is connected to an open Ethernet/IP network
No impact on redirects and other local operations
The admin(s) of the organization of your device were notified by email.
On the following diagram, you can see the impact if the GSM connection is interrupted (in red)
Reactivation
When a hardware becomes active again :
● its sim card is reactivated ● the restriction are removed
