6.Product installation #


Mounting options

Fixing magnet

The TYNESS-FIX-AIMANT kit contains 2 round magnets, two solid metal washers and 2 fixing bolts (Torx T8 imprint).

It makes it possible to fix the TYNESS on every on any magnetic surface or, for the non-magnetic surfaces, on the washers provided. In this specific case, the washers must be fixed to the surface (for example, using a double-sided adhesive).

Installation :

  1. Remove the solid washers from the magnet by sliding them sideways
  2. Position the magnets in the slots provided for this purpose on the back of the case. The face containing the entry cone must be visible.
  3. Insert the screw into the magnet and screw.
  4. To use the metal washers, place them on the magnets, add the adhesive on them and position the Tyness case. Once the adhesive holds, remove the case.


DIN rail mounting

The TYNESS-FIX-RAIL contains 2 parts: a base and a movable and adjustable strip.
It is used to fix the Tyness horizontally or vertically on a DIN rail. On horizontal position, it allows to position the Tyness at two heights per position.

The Tyness can be removed from the DIN rail by manipulating the movable strip with a classic screw-driver.
The TYNESS-FIX-RAIL comes with 2 mounting screws

Installation :

  1. Place the support in the chosen position (horizontal or vertical) and at the required height
  2. If needed, adjust the strip height
  3. Screw the 2 screws.



Strip setting :

Depending on the positioning of the FIX-RAIL, the strip must be adjusted to remain accessible.

If the upper part of the strip protrudes from the TYNESS (for example with a TYNESS in a low position), it can be cut off using cutting pliers.


7.Power supply #

Power mode

The Tyness can be powered using one several different modes:
– External power using a power pack (see TYNESS-ALIM-BLOC-5V) or a DIN rail power supply (see ALIM-RAIL-5V)
Option : External case containing a 3.6V lithium battery operation, refer to the battery icon next to the extension boards in the product catalog. (see TYNESS-OPT-PACK-PILE)

Warning : not all extension boards are compatible with the use of a battery as power supply. Refer to each extension board documentation.

External power supply

The power supply voltage must deliver 5V DC and provide a minimum current of 1A, or 2.5A if using the Tyness with the 4G option
It is very important to respect the polarity indicated on the printed circuit when connecting the power supply.

Note : You have 30 seconds to connect the software after powering on the Tyness. If you have waited too long, disconnect and reconnect the cable in order to restart the usb connection.

Main page

Once connected to the Tyness, the software automatically displays different information:

  • The version of the internal software. In our example: V1.18
  • Additional cards detected : Rogowski and PT100
  • Type of communication configured : LoRaWAN™


The Tyness is a product that always evolving, because we regularly add new features and additional cards.

To update your product, simply :

  • Download the latest firmware version from the Tyness section on the Ewattch website
  • Click the “Load” button to select the previously downloaded file.
  • Validate the update by clicking on the “Upgrade” button
  • A progress bar indicates the status, and a window indicates that the update has been completed successfully.


There are 4 modes of communication currently available:

  • LoRaWAN™ : LoRaWAN™ communication on private or managed networks.
  • LoRa® : Communicate with an EWATTCH Toolbox or with a Tyness configured in 4G + LoRa®
  • 4G : Transmits data in 4G directly to a server
  • 4G + LoRa® : Same, and also can concentrate data from other LoRa®  sensors located in its range.

4G and 4G+LoRa®

To configure the chosen communication mode, select one of the modes and click on the corresponding “write” button.

If you choose “4G” or “4G+LoRa®” modes, you must indicates the settings of your carrier’s network and your SIM card
– PIN code: “0000” by default
– APN : which is the name of the network acmes point, here “orange.fr”
– User / Password : which are the identifiers that allow access to the network.

On the TYNESS :
The LED light on the 4G module gives information on the status of the communication

SIM card insertion:

In its 4G version, the TYNESS is equipped with a micro SIM card reader (3FF).
The card should be inserted with the beveled corner at the bottom right.
Insert it to the bottom until you hear a slight “click”. When the card is correctly inserted, the card presence indicator is vertical (see photo below).



If you choose the LoRaWAN™ communication mode, you have access to different keys and configurable options, allowing you to set up your TyNess:

  • APP EUI : This unique application identifier allows the objects to be grouped together. This 64-bit address allows the peripherals to be classified by application
  • APP KEY : This is a secret key shared between the peripheral and the network, which is used to create the session keys.
  • DEV EUI : This is a factory programmed identifier which makes each object unique.
  • Messages confirmed : parameter allowing to ask the network for a reception of the frames sent by the sensor confirmation. Improves the quality of exchanges.
    Please note: This is an extremely energy and bandwidth consuming function. Not to be used systematically.
  • Adr enabled : ADR (Adaptive Data Rate) mode activated or not. This mode allows the network to automatically adapt the communication speed and the signal strength of the sensor. If this parameter is not activated, the sensor exchanges in SF12 only.
  • Periodic rejoin activated : When activated, the Tyness will launch a network join procedure every week. If not activated, once a network is joined no further join procedure are made.
  • Compliance test enabled : Do not activate. Only to be used for network testing.
Network connection process
  • Our products try to connect to the network when they start.
  • If it does not work, they will retry every 24 hours until it works.
Periodique network reconnection
  • Our products restart a network connection procedure every 7 days.
    These reconnections improve security.
    Indeed, reconnection to the network renews the encryption keys.
    With the Tyness, this functionality can be activated or deactivated using the “periodic rejoin” option of the configuration software.

Cloud ApiKey

This key is only used with 4G communication to secure exchange with the server.

With EwattchCloud, the user must copy this key during configuration of a Tyness.

EwattchCloud exemple:

LoRa channel

In LoRa® (LoRa®-Ewattch) mode, the Tyness has multiple communication channels to choose from:

  • 2 fast channels. Allowing to send data more frequently but over shorter distances.
  • 5 long range channels. Allowing to send data over greater distances but less frequently.

Channel must be selected in LoRa and LoRa + 4G mode.
After selecting the channel, click on the write button to save your configuration.

In order for a LoRa-Ewattch Sensor and a LoRa-Ewattch gateway to communicate, the 2 products must be configured to use the same channel.
