Description

The MyMB interface / actuator for Modbus systems is a fundamental tool for achieving the objectives of Predictive Maintenance, Adaptive Energy Management, qualitative data analysis and remote programming of parameters for proper operation of the systems. It has communication capabilities both through a Sigfox M2M network, through a gateway equipped with a transceiver with Z-Wave protocol, and through Wi-Fi. Through these protocols it will be possible to send the information received to a big data management cloud system to evaluate, through a Predictive Maintenance process, the implementation of automatic customer support processes.

With this table you can connect the device to IoB cloud. A few tips that can aid you:

1.  Pay close attention to the Modbus link. It has polarity.
2. Pay close attention to the 5V power supply respecting the + and – as in table 1.
3. Pay close attention to the SIGFOX antenna. It must be tightly screwed otherwise the data to the portal could fail and the radio module could be seriously damaged.

Warning LEDs

The IoB device has one green warning LED and one red warning LED.
The green LED indicates the state of OpenTherm Thermostat connection:

1 flashing every 3 seconds| MyMB device is connected with the

Modbus device.

---|---

2 flashing every 3 seconds

| MyMB device is working and there is no request for heating.
LED on and with 2 shutdowns every 3

seconds

| MyMB device is working and there is a

request for heating.

The flashing red LED indicates anomalies:

module.

5 flashes + pause| No Wi-Fi connection and/or Internet

communication.

Wi-Fi Error. Possible causes:

• No connection to the local network.
• No connection to the SmartDHOME server (no Internet connection, server temporarily unavailable, etc).

Wi-Fi Configuration

WARNING! The device has several communication modes that cannot be configured at the same time. Choose the one you prefer before proceeding with configuration.

WI-FI Configuration using application (recommended)

To configure the device, download and install the IoB application on your smartphone. After that, set the MyMB in programming mode, turn on the device and press the functions button for 3 seconds.

Upon release of the button, the device will enter configuration mode and the LEDs will flash alternately (red and green). In this way, you will can connect to a new Wi-Fi called “IoB” to begin the device configuration.
Open the IoB application and press the Set Remote Server/Wi-Fi button in the Home (see image). After that, click on CONTINUE on the pop-up that will appear.

Swipe on the Wi-Fi section (see image) and press on the symbol to see the complete list of detected Wi-Fi. Select the correct one and enter the password. Click on SAVE.
If Wi-Fi is not present or visible, press the reload button.
If the operation is successful, a configuration message will be visible at the bottom of the screen.
To end the process, press the CLOSE button on the top right. The LEDs on the MyMB device will stop flashing alternately.
At the end of the Device Configuration, the IoB will be operational with the new configuration. In case of configuration failure, or to cancel it, press the RESET button and the device will restart.

WI-FI Configuration without using application (choice reserved for

professionals and experts)

WARNING! Any type of intervention by our technicians, which will be caused by an incorrectly performed installation or by a failure caused by the customer, will be quoted and will be charged to those who purchased the system.
If you have a good experience with this type of device, you can configure the MyMB without using the application:

1. Switch on the device.
2. Press the FUNCTIONS button for 3 seconds.
3. Release the button and verify that the device is in configuration mode. The LEDs will flash alternately (red and green).
4. Connect your smartphone at the Wi-Fi network with SSID IoB (no password).
5. Establish the connection, open the browser and enter the following link and press ENTER: http://192.168.4.1/sethost?host=iobgw.contactproready.it&port=9577 A white screen with the inscription OK will be displayed.
6. Open the browser and enter the following second link: http://192.168.4.1/setwifi?ssid=nomerete&pwd=passwordwifi Insert instead of nomerete the SSID of the network you want to connect to. Enter instead of passwordwifi the Key of the Wi-Fi chosen. A white screen with the inscription OK will be displayed.
7. Open the browser and enter the following third link: http://192.168.4.1/exit A white screen with the inscription EXIT will be displayed.

Z-Wave Configuration

WARNING! The device has several communication modes that cannot be configured at the same time. Choose the one you prefer before proceeding with configuration.

Inclusion/Exclusion in a Z-Wave network

If you have an MyMB Z-Wave version, you can include or exclude the MyMB device in a Z-Wave network. First of all, read the user manual of your Z-Wave Gateway to understand how to include or exclude a device. After this you can include/exclude the MyMB module into a z-wave network by pressing the link button for 8 seconds.

Data Mapping

MyMB device supports the following command class:

• COMMAND_CLASS_BASIC
• COMMAND_CLASS_SWITCH_BINARY
• COMMAND_CLASS_THERMOSTAT_SETPOINT
• COMMAND_CLASS_SENSOR_MULTILEVEL

These are described in the following sections.

COMMAND_CLASS_BASIC

This command class can be used to switch the boiler on/off (or to know the current status). However, the auto-report of this CC was not implemented for performance reason. Therefore, to perform the same operation is recommended to use the COMMAND_CLASS_SWITCH_BINARY.

COMMAND_CLASS_SWITCH_BINARY

This command class can be used to switch the boiler on/off (or to know the current status). Moreover if, for external reason, the boiler switch itself on/off an auto-report to node 1 of the network is triggered.

COMMAND_CLASS_THERMOSTAT_SETPOINT

This command class can be used to manage the setpoints of the boiler. Is important to known that the max and min value of these setpoints are not reported by this command class (the reported values are just a ‘small’ minimum and a ‘big’ maximum). These values are instead reported with the CONFIGURATION command class. This was done to support the write operation of these 2 values in some future developments. The map between the ‘mode’ and the setpoint is as below, while the unit of each measure is communicated correctly in the report message of the command class.

Mode (dec)| Measure|
---|---|---
1| Heating Setpoint
2| Cooling Setpoint
13| DHW Setpoint

COMMAND_CLASS_SENSOR_MULTILEVEL

This command class maps a series of measures that are obtained from the boiler. The map between the ‘Sensor type’ and the provided measure is as below, while the unit of each measure is communicated correctly in the report message of the command class.
