This section gives you a quick understanding of how to connect your device to WSO2 IoT Server and start using it. For this purpose, let's use the virtual fire alarm.
The virtual fire alarm is a virtual device that mimics the functionality of a real fire alarm. Therefore, for this use case you do not need a real device. Once you start the virtual fire alarm, it will connect to the WSO2 IoT Server and push the temperature readings it collects. The device supports MQTT and XMPP communications and is configured to use MQTT by default.
The following subsections explain how you can work with the virtual fire alarm:

Follow the instructions given below to start WSO2 IoTS, and sign into the IoTS device management console: Navigate to the WSO2 IoT pack plugins and run the plugins-deployer.xml.
Example: | Code Block |
|---|
cd <IoT_HOME>/plugins
mvn clean install -f plugins-deployer.xml |
Start WSO2 IoT Server by starting the three profiles in the following order: Start the broker profile, which corresponds to the WSO2 Message Broker profile. | Code Block |
|---|
cd <IoTS_HOME>/broker/bin
./wso2server.sh |
The default port assigned for the broker is 9446. Start the core profile, which corresponds to the WSO2 Connected Device Management Framework (WSO2 CDMF) profile. | Code Block |
|---|
cd <IoTS_HOME>/core/bin
./wso2server.sh |
The default port assigned for the core is 9443. Start the analytics profile, which corresponds to the WSO2 Data Analytics Server profile. | Code Block |
|---|
cd <IoTS_HOME>/analytics/bin
./wso2server.sh |
The default port assigned for analytics is 9445.
Access the device management console by navigating to https://<HTTPS_HOST>:<HTTPS_PORT>/devicemgt.
Example: https://localhost:9443/devicemgt Enter your username and password.

| Follow the steps below to define a policy for the fire alarm device and start the advanced agent fire alarm. Click the menu icon Image Added , and click Policy Management. Click Add New Policy and select the Virtual Fire Alarm platform. Configure a policy using the Siddhi Query Language and click Continue.
The following is an example of a policy you can use for the Fire Alarm device. See Adding a Policy for more information on how to add your own policy. | Code Block |
|---|
define stream fireAlarmEventStream (temp int);
from fireAlarmEventStream#window.time(30 sec)
select max(temp) as maxValue
insert into analyzeStream for expired-events;
from analyzeStream[maxValue < 50]
select maxValue
insert into bulbOnStream;
from fireAlarmEventStream[temp > 50]
select temp
insert into bulbOffStream; |
- Assign the policy to user roles or users and select an action to be triggered upon non-compliance.
For example, you can assign the policy to the admin user role and select Enforce as the action upon non-compliance. For more information, see Adding a Policy.
