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.

With this table you can connect the device to IoB cloud. A few tips that can aid you:
1. Boiler and Thermostat OpenTherm connections have no polarization.
2. Pay close attention to the 5V power connection respecting the + and -.
3. Pay close attention to the aerial. It must be well screwed otherwise the data to the
portal could fail and the radio module could suffer serious damage.
Warning LEDs
The IoB device has one green warning LED and one red warning LED.

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 MyOT 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.

Data Mapping
MyOT 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.
