Description
The MyMB interface/actuator for ModBus systems is a fundamental tool for achieving predictive maintenance,
adaptive energy management, qualitative data analysis and remote parameter programming objectives for
correct system operation. 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.

Luminous signals
The IoB device has two signal LEDs, one green and one red.
The green LED signals the status of the ModBus connection to the thermostat:
1 flash every 3 seconds
MyMB successfully connected to the system.
2 flash every 3 seconds
MyMB is working as if it were connected to a
thermostat with ON/OFF contact.
On and with two offs every 3 seconds
MyMB in thermostat ON/OFF mode with heating
request in progress.
The red LED, if flashing, signals the following anomalies:
2 flashes + pause
ModBus communication is missing.
3 flashes + pause
The device works properly.
5 flashes + pause
Lack of Wi-Fi connection and/or internet
communication.
The error signal on the Wi-Fi network can concern both a failed connection to the local network and a failed
connection to the SmartDHOME server (internet failure, server temporarily unreachable, etc.).
Compatible devices (SmartDHOME)
The MyMB can be connected to multiple devices in our catalog; so that the latter can interface with the
MyVirtuoso Home building automation system. All the devices compatible and manageable with this actuator
are listed below.

Wi-Fi setup
ATTENTION! Although the device has multiple communication modes, they cannot be configured at the same
time. Before configuring the device, carefully choose the desired type of communication.
ATTENTION!!! If you have an active license to use the Contact Pro IoT platform, you can carry out the
following procedure (choice 1). If you do not have an active license and need to use the IoB app, you
must contact your sales representative in order to proceed with the purchase of a new license.
Otherwise you can proceed with the configuration by following the procedure below (choice 2).
Wi-Fi configuration with App (choice 1)
For a correct configuration of the device, it is necessary to download and install
the IoB application on your smartphone. Then set the MyMB in programming
mode, turning on the device and pressing the function key for about 3 seconds.
When the button is released, the device will enter configuration signaling the
status with an alternate flashing of the LEDs (red and green). This will create
the "IoB" Wi-Fi to which you will need to connect to proceed with the
configuration.
At this point it is necessary to open the application installed at the beginning.
Once inside, press Set up Remote Server/Wi-Fi on the Home screen (see
image on the left) and click on continue in the pop-up that will appear.
On the page that will open, move to the Wi-Fi section (see image). Then press
the key to view the list of Wi-Fi detected by the device. Select the correct
one, enter the password and press SAVE. If the Wi-Fis are not present or visible,
press the reload button on the list.
The operation was successful, a message of successful configuration will be
visible at the bottom of the screen.
To end the process, press the Close button at the top right. The LEDs on the
MyMB device will stop flashing alternately.
At the end of the programming procedure, the device will be operational again
with the new configuration. In case of unsuccessful programming, or to cancel
it, press the RESET key and the device will restart.

Wi-Fi setup without application (choice 2)
ATTENTION! Any type of intervention by our technicians, which will be caused by an incorrectly performed
installation or by a fault caused by the customer, will be quoted and will be charged to whoever purchased
the system.
If you have good experience with this type of device, you can configure the MyMB without using the application:
1. Turn on the device.
2. Press and hold the function key for 3 seconds.
3. Release the button and check that the device is in programming mode (alternating red and green
flashing).
4. Connect your smartphone to the Wi-Fi network with SSID IOB (no passkey required).
5. Once the connection is established, open the navigation application 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 word OK will appear.
6. Continue entering the link:
http://192.168.4.1/setwifi?ssid=nomerete&pwd=passwordwifi
Instead of network name, enter the SSID of the network you want to connect to and instead of wifi
password, enter the key of the chosen Wi-Fi network. A blank page with the wording OK will appear.
7. Insert the third and last link:
http://192.168.4.1/exit
A blank page will appear with the wording EXIT.

Mappatura dei dati
The MyMB device supports the following command classes:
1. COMMAND_CLASS_ASSOCIATION
2. COMMAND_CLASS_ASSOCIATION_GRP_INTO
3. COMMAND_CLASS_BASIC
4. COMMAND_CLASS_SWITCH_BINARY
5. COMMAND_CLASS_THERMOSTAT_SETPOINT
6. COMMAND_CLASS_SENSOR_MULTILEVEL
7. COMMAND_CLASS_METER
8. COMMAND_CLASS_FIRMWARE_UPDATE_MD_V2
9. COMMAND_CLASS_SECURITY
The most important are described below.
COMMAND_CLASS_BASIC
This class can be used to turn on/off the boiler (or to know its Current status). However, it must be specified
that the auto-report of this CC has not been implemented. It is therefore recommended to use the CC
COMMAND_CLASS_SWITCH_BINARY.
COMMAND_CLASS_SWITCH_BINARY
This CC can be used to turn the boiler on/off (or to know its current status). It also periodically generates self-
reports of the current status to node 1 of the network.
COMMAND_CLASS_THERMOSTAT_SETPOINT
This CC can be used to manage the boiler setpoints.
N.B. The maximum value and minimum value of the setpoints are displayed with the CONFIGURATION
command class. This is to support a system hot swap without lock/unlock. It is also important to know that
setting the setpoint value to 0 is equivalent to setting it to 40°C.
Below is the map between "mode" and the setpoint, while the unit of each measurement is communicated as
per specifications in the CC report message.
