MQTT - blusensor/blusensor-developer GitHub Wiki
All our Wi-Fi sensors directly support MQTT. You can also use your own MQTT broker
Please update to the latest firmare V1.1.0. This release contains important bugfixes for local MQTT networks. For updating your sensors, please select "bluSensor IOT" as your IoT provider and use the iOS/Android app to trigger the firmware update.
Alternatively, you can sent the following MQTT command to your device:
TOPIC
iot/blusensor/v1/things/<serialnr>/control
MESSAGE
{"ota": "1.1.0"}
Once the sensor is starting the update, it will blink in blue.
Please note, that the sensor needs public internet access to download the firmware update.
In order to connect a bluSensor device to your MQTT broker you need to configure the IoT connection on your sensors. In order to do so, you need to put the device into ADMIN MODE. The device will make a Wi-Fi hotspot (name=serialnumber) that you can connect to.
Once connected you can open the URL: http://192.168.4.1
Select the menu item "Internet of Things" to configure your sensor. Next select "MQTT" as your provider and fill out the "Endpoint Configuration".
Once your configuration is finished, you need to restart the device. You can check our iOS/Android app for connection states. Detailed informations can be found on the sensor's information page.
The default password is "123456", but you can change that anytime.
You need to connect your sensor to a Wi-Fi network. This can be done on the first page of the admin dashboard or you can use our app for iOS and Android
If you are using mosquitto with its default configuration (non-TLS) you need to configure your sensor like this
The sensor will send updates every 60 seconds.
iot/blusensor/v1/things/<SERIALNR>/telemetry
iot/blusensor/v1/things/<SERIALNR>/device
iot/blusensor/v1/things/<SERIALNR>/alarms
- SERIALNR = world-wide unique sensor serialnumber (18 characters)

You can use our public MQTT broker free of charge. If your project requires a dedicated and private MQTT broker or if you want to use your own broker, you can use our app (bluSensor® AIR) to configure your sensors to connect to it. Using TLS and client certificates (stored on the sensor) is also already supported! Please contact us for details!
mqtt.blusensor.com
Available Ports
8883 (TLS)
8081 (websockets,TLS)
The shared MQTT broker only support TLS connections and user authentication is mandatory from now on.
user=blusensor
pass=123456
You need to use the serialnumber of your sensor as the client ID
client_id=<serialnr>
Any device connected to the broker can only subscribe and publish to its own topic
iot/blusensor/v1/things/<client_id>/#
Our legacy public broker.blusensor.com will be running until 30.11.2022.
You can use any MQTT client to connect to our broker and subscribe to your sensor's data.
Note: do not use the same client id as your sensor! The broker only supports one connection per client ID.
We can recommend MQTT X! https://mqttx.app/
