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.

Device Connections
To operate the device, you have to understand the utility of the green connector (see Tab. 1)

SIGFOX/ZWAV E AERIA

Figure 2: Aerial and green connector.

Tab. 1: green connector

Z-WAVE AERIAL| 1OpenTherm boiler| 2OpenTherm boiler| 3OpenTherm thermostat| 4OpenTherm thermostat| 5GND (-)| 6+5V (+)
---|---|---|---|---|---|---

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.
---|---
2flashing every 3 seconds| MyOT works as if it were connected to a chronothermostat with ON/OFF contact (traditional system)
LED on and with 2 shutdowns every 3 seconds| MyOT in ON/OFF chronothermostat mode with heating request in progress.

The flashing red LED indicates anomalies:

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 http://info@smartdhome.com.

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 orvisible, 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. f 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  password wifi theKey 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! 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 selfreport 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.

COMMAND_CLASS_SENSOR_MULTILEVEL

This CC provides a series of measurements which are obtained from the boiler. Below is the mapping between the “sensor type” and the “supplied measurement”. The unit of each measure is communicated as specified in the CC report message

COMMAND_CLASS_CONFIGURATION

This CC provides a series of measurements which are obtained from the boiler. Below is the mapping between the “Parameter number” and the supplied “Parameter”.

Parameter number (dec)| Parameter| Bytes| Mode (Read/ Write)| Sign
---|---|---|---|---
90| ID LSB| 4| R| NO
91| Version| 2| R| NO
94| ID HSB| 4| R| NO
95| Report rate (minutes, 0: continuous)| 4| R| NO
96| Other report frequency (minutes, 0: continuous)| 4| R| NO
1| Max setpoint of the boiler| 2| R| NO
2| Min boiler setpoint| 2| R| No
3| Setpoint Max DHW| 2| R| No
4| Setpoint Min DHW| 2| R| No
30| Summer mode (0: no 1: yes)| 1| R/W| No
31| Enabling DHW (0: no 1: yes)| 2| R/W| No
10| Error flag if present (0 otherwise)| 2| R| No
11| Error code if present (0 otherwise)| 2| R| No

COMMAND_CLASS_SECURITY

MyOT device supports unauthenticated S0 and S2 security
