What happens if my Box lost network connection ?

This article is about the Tower or Bridge network connection lost.

Wattsense always helps customers to get the best remote connectivity by monitoring and identifying issues at a very early stage. However disconnection sometimes takes place because the remote connection fades.

At Wattsense, our customers’ data delivery is a priority.

Our solution is designed to overcome such situations when the Tower or the Bridge (Remote Bridge) can’t upload data to the server. There are mechanisms in place to retain data (100K measurements) during that blackout period and send the data to the server when communication is reestablished.

In case the disconnection is extended for more than a day and the device does not pick up the network, please follow this procedure:

Do not reboot or switch off the Tower or the Bridge
Contact your support representative at Wattsense by submitting a technical support request here

Step 1 is very important to avoid losing data.

Wattsense will get in touch with you right away and investigate the root cause.

If you have any problem, please do not hesitate to contact us: Wattsense Support

General information on BACnet

BACnet (Building Automation and Control Networks) defines a set of standard object types that represent various components, devices, or systems in building automation. Each object type contains properties that describe its functionality and enable interaction.

The following diagram shows a BACnet network in the Wattsense environment :

Article.HowToCreateMyBacnetNetwork.Schema.png

Principle of BACnet scanning

Scanning a BACnet network typically involves discovering devices and their associated objects on the network. BACnet uses the Who-Is and I-Am services for device discovery.

Who-Is Command
This command broadcasts a request to identify all BACnet devices on the network.

Devices on the network will reply with I-Am messages, which typically contain:

Device Instance ID
Network Address
Device Object Name

Query Device Objects
Once devices are identified, a request can be sent to read objects properties.

You can use software tools like Yabe (Yet Another BACnet Explorer) interface to perform these actions:

Launch the tool and configure the network settings (e.g., BACnet/IP port and broadcast address).
Perform a Who-Is broadcast.
View the list of devices responding with I-Am.
Select a device and explore its objects and properties.

BACnet objects

The Wattsense console BACnet scan module can explore and display basic informations (type, name, description) for all kind of objects (BACnet standard ANSI/ASHRAE 135-2020).

Additionally, the properties of multiple objects (supported objects) can be manipulated (read and/or write access). This functionality mainly concerns the Present_Value property.

Here is a listing of supported BACnet objects by Wattsense :

Object Syntax	Object Name	Description
Analog Objects
OBJ_ANALOG_INPUT (0)	Analog Input (AI)	Represents continuous input values like temperature or pressure.
OBJ_ANALOG_OUTPUT (1)	Analog Output (AO)	Represents continuous output values like setpoints.
OBJ_ANALOG_VALUE (2)	Analog Value (AV)	Represents continuous values used internally or for integration.
Binary Objects
OBJ_BINARY_INPUT (3)	Binary Input (BI)	Represents discrete input states (e.g., open/closed).
OBJ_BINARY_OUTPUT (4)	Binary Output (BO)	Represents discrete output states (e.g., on/off).
OBJ_BINARY_VALUE (5)	Binary Value (BV)	Represents discrete values used internally or for integration.
Multistate Objects
OBJ_MULTISTATE_INPUT (13)	Multistate Input (MSI)	Represents inputs with multiple states (e.g., selector switches).
OBJ_MULTISTATE_OUTPUT (14)	Multistate Output (MSO)	Represents outputs with multiple states (e.g., fan speeds).
OBJ_MULTISTATE_VALUE (19)	Multistate Value (MSV)	Represents multistate values used internally or for integration.
Schedule and Calendar Objects
OBJ_SCHEDULE (17)	Schedule	Represents time-based scheduling of values or events.
Other Control and Utility Objects
OBJ_CHARACTERSTRING_VALUE (40)	Character String Value	Represents text data storage or display.

BACnet properties

Each object contains a list of properties.

Missing Data? How to debug?

Are you encountering data loss or missing data with your Bridge or Tower? A good starting point is to follow these steps to comprehend and troubleshoot the problem:

Step 1: Verify the Box connectivity

For a Bridge: Ensure you have correctly interpreted the Bridge's status: Bridge connection status in the Wattsense console.

For a Tower: Confirm that the Tower is properly connected and all statuses are green in the user console.

If not:

Inspect the hardware to ensure the device is correctly powered and all LEDs are functioning as expected.

Step 2: Verify Protocol connectivity

Ensure you have consulted the dedicated tutorials for each protocol provided with our products. Following these guides will help you determine if the issue originates from there.

How to read the LED status of the Wattsense boxes

This article describes the meaning of the LED status of the Wattsense Tower or Bridge. The LED lighting is available for each type of communication interface (Ethernet RJ45, RS485, USB, KNX …) as well as the box power supply.

Full description table

For wired protocols: such as Ethernet RJ45, KNX, M-Bus, Modbus RS485, and LPB (X-Bus), the LEDs blink when there is traffic on the bus and remain off when in standby mode.

For wireless protocols: The LoRaWAN LED is not monitored, so it remains off, while the GSM LED blinks when connected to the GSM network.

For box status: The power supply LED should be on, and the Heartbeat LED should blink.

Can I fetch my data from more than two years ?

This article explains how to fetch all the data from more than two years.

Wattsense stores data in two different locations, in a database that we qualify as "hot", i.e. data is immediately accessible via the API, and is archived in a "cold" storage location. Data's lifecycle is as follow:

When data is received it's available in the user console and using the List Device Properties Values API
The next day, the data can be recovered using the Request an archive API. (Data is available over two rolling years (since Jan 26th 2024))
Then, when data is no longer accessible via the archive API : you have to use Archive retrieval API.
At the end of your device subscription, you are offered a delay of 6 months to download your archives, before they are permanently removed
