RFID Reader Configuration

Create and configure the following elements on the online portal:

  1. Sensor (gives relay ON/OFF status)
  2. Counter
  3. Relay
  4. RFID reader

Although the Shelly and SDM530C are a meter, relay and sensor, they must be created separately.

1. Sensors

The sensors are used by the system to know the closed or open (ON/OFF) status of the relay.

Under sensors, add a sensor. Parameters depending on the model:

Eastron SDM530C (Modbus RTU)

  • Name : Unique name that identifies the device, its location, and the solution. Ex. Relay counter Laundry room no. 1.
  • Type : State On/Off
  • Address : Unique Modbus primary address from 1 to 250.

Save the address into the device directly. See Eastron SDM530C user manual.

  • Register : 0
  • Protocol : modbus
  • Model : SDM530C

  • Playback frequency : 900 (recommended)
  • Asynchronous : coché

This is the physical reading frequency of the sensor.

  • asynchronous unchecked: the sensor is read physically and the status of the relay is sent at the defined reading frequency.
  • asysnchronous checked: the sensor is physically read at the defined reading frequency but the status of the relay is sent only if it is different from the last reading. In any case, statuses are sent every hour.

The services (washaccess, optimization or ebike) read the sensors and activate the relays when requested, but these services never send the status of the sensor.

For relays used by the Optimization service, set a frequency lower than 60 seconds, but not lower than 30 seconds.

Eastron SDM530C (Modbus TCP)

The SDM530C relay meters can communicate via ModbusTCP using an RS485-Ethernet converter.

The configuration is like the one above except for the following settings:

  • Protocol : modbustcp
  • Model : SDM530C_TCP
  • Additional parameters : {'server_ip': 'ADRESSE IP DU CONVERTISSEUR', 'server_port': 502}


  • Name: Unique name that identifies the device, its location, and the solution. Ex. Shelly Bike socket no. 1.
  • Type: State on/off
  • Address: 0
  • Registry: ison
  • Protocol: API
  • Model: Shelly
  • Additional parameters: see below

Start the Shelly and connect to the WiFi network it transmits. The SSID is shelly1-XXXXX.

Open a web browser and connect to the Shelly's default IP address: .

Under "Internet & Security" --> "WIFI CLIENT MODE" --> Check "Connect the Shelly device to an existing WiFi Network" and enter the local WiFi settings (SSID and PASSWORD).


Under "Internet & Security" --> "Restrict Login" --> Check "Restrict the web interface" and enter "admin" in the User field and a unique secure password.


Set a fixed IP address for the Shelly in the router (local LAN network) and restart the Shelly. See 4G Router Configuration.

Save the IP defined above preceded by http:// , the username and password chosen in additional parameters as formatted below:

'api_address': '',
'api_username': 'admin',
'api_password': 'admin'

2. Counter

Create a counter under the Counters tab.

Parameters identical to the Sensors paragraph above.

In the case of using the SDM530C with Modbus TCP, choose the model: eastron_modbus_tcp and under additional parameters:







3. Relay

Create a relay under the Sensors/Relays --> Sensors tab

Parameters same as Sensors above.

Link the relay to a sensor.

4. RFID reader and linked object

Add an RFID reader

Add an RFID reader under the RFID Readers tab.

  • Name : Unique name that identifies the device, its location, and the solution. Ex. RFID reader Laundry room no. 1.
  • Model : InveoIndLed_HTTP_GET without keyboard or InveoIndLed_Keyboard_HTTP_GET with keyboard
  • Address (modbus): 1 (generally we leave address 1 by default)
  • Additional parameters : specify the connection parameters of the RFID reader connected via Ethernet (IP address, port, username and password) in accordance with the format below:
{'server_ip': '',
'server_port': 502,
'username': 'admin',
'password': 'admin00'}

  • Related solution: WashAccess or eBike

Add a linked object

Click on + of the RFID reader created above.

  • ID (Number): if the player is equipped with a numeric keypad, enter the socket number.

Ex: 1 , 2 , 2 etc. or 1111 for InveoIndLed_Keyboard_HTTP_GET

Socket numbers must have 4 digits.

For readers without a keyboard ( InveoIndLed_HTTP_GET ), put something unique.

  • Relay: Select relay
  • Associated sensor (ON/OFF): Select the sensor corresponding to the relay
  • Associated counters: Select one or more counters. Normally the counter corresponding to the relay counter.

At least one meter (generally electric). Possibility of also associating a water meter for Washaccess, for example.

5. Inveo RFID Card Readers

Inveo RFID readers connect via Ethernet and can be powered separately or via PoE (Ethernet).

Connect the reader to a computer, use the address to access the web interface.

Default username: admin

Default password: admin00


Enable DHCP in Network and connect the device to the same network as the computer and the Gateway. Set a fixed IP address for the player via the network router's web interface.

Check DHCP (or define a fixed IP according to the desired network parameters)
