Description
The MyOT interface/actuator for OpenTherm boilers 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.

Here are some tips:
1. The OpenTherm connection for both the boiler and the chronothermostat has no polarization.
2. Pay close attention to the 5V power supply connection respecting the + and - as in table 1.
Warning LEDs
The IoB device has two signaling LEDs, one green and one red.
The green LED signals the status of the OpenTherm connection to the chronothermostat:
1 flashing every 3 seconds
The MyOT device is connected with the OpenTherm
Thermostat.
2 flashing every 3 seconds
MyOT works as if it were connected to a
chronothermostat with ON/OFF contact (traditional
system).

No Wi-Fi connection and/or Internet communication.
The error report on Wi-Fi can concern both a lack of connection to the local network and a failure to connect to the
SmartDHOME server (lack of Internet, server temporarily unreachable, etc.).
Wi-Fi Configuration
ATTENTION! Although the device has multiple communication modes, they cannot be configured at the same time. Before
configuring the device, it is advisable to carefully choose the type of communication desired.
ATTENTION! To use the application, it is necessary to purchase a paid package of the IoB portal. Please contact the sales
representative or the company by sending an email to [email protected].
WI-FI Configuration using application (recommended)
For correct device configuration, you need to download and install the IoB application on your smartphone. Then set the
MyOT in programming mode by 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 alternating
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
entered, press Set the 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 opens, 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-Fi is not present or
visible, press the reload button in the list.
The operation was successful, a successful configuration message 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 MyOT
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 missing
programming, or to cancel it, press the RESET key and the device will restart.
Wi-Fi configuration without application (not recommended)
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 good experience with this type of device, you can configure MyOT 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. Once the connection has been 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 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.

Z-Wave Configuration
WARNING! Although the device has multiple communication modes, they cannot be configured at the same time. Before
configuring the device, it is advisable to carefully choose the type of communication desired.
Inclusion/Exclusion in a Z-Wave network
If you have the Z-Wave version, you can include or exclude the MyOT device in a Z-Wave network. To do this, first of all
consult the manual of your gateway to learn how to include and exclude devices. After that it is possible to include/exclude
the MyOT device by pressing the function button for 8 seconds.
Data Mapping
MyOT device supports the following command class:
•COMMAND_CLASS_ASSOCIATION
•COMMAND_CLASS_ASSOCIATION_GRP_INFO
•COMMAND_CLASS_BASIC
•COMMAND_CLASS_SWITCH_BINARY
•COMMAND_CLASS_THERMOSTAT_SETPOINT
•COMMAND_CLASS_SENSOR_MULTILEVEL
•COMMAND_CLASS_METER
•COMMAND_CLASS_FIRMWARE_UPDATE_MD_V2
•COMMAND_CLASS_SECURITY
These are described in the following sections.
COMMAND_CLASS_BASIC
This class can be used to switch the boiler on/off (or to know its current status). However, it must be specified that the self-
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 switch the boiler on/off (or to know its current status). Furthermore, if, due to an external cause,
the boiler switches on/off independently, an auto-report is activated at node 1 of the network.

COMMAND_CLASS_THERMOSTAT_SETPOINT
This CC can be used to manage the boiler setpoints.
N.B. The maximum and minimum value of the setpoints are displayed with the COMMAND_CLASS_CONFIGURATION.
This was done to support a non-exclusion/inclusion boiler hot swap. It is also important to know that setting the heating
setpoint to 0 is equivalent to setting it to the maximum reported by the boiler. Otherwise, setting the DHW setpoint to 0 is
equivalent to setting it to 40 ° C. The map between the 'mode' and the setpoint is as follows, while the unit of each
measurement is correctly communicated in the command class report message.
