smartDEN Notifier - IoT Module with MQTT, eMail Alerts, XML/JSON API
smartDEN Notifier is an Ethernet input module that can be used in a wide range of remote monitoring, measurement, data-acquisition, security and alert notification applications. Thank to its multi-channel design (16 digital, 8 analog and 8 thermistor inputs) this device can perform simultaneously a variety of measurements, for example temperature, humidity, light, pressure, voltage, current etc. The Web interface allows users to configure the smartDEN Notifier, as well as to monitor current measurements. Supported by DRMv3 Software. Along with the current measurements can be downloaded from a remote IP host in XML/JSON format, smartDEN Notifier is capable to send alerts and notifications via MQTT protocol and e-Mail. Works with Home Assistant, Domoticz and OpenHAB home automation systems as well as with Node-RED IoT platform.

SmartDEN Notifier Overview
SmartDEN Notifier is shipped with one NTC thermistor sensor B57500M Epoxy Resin (up to 8 such sensors are supported by singe module). However additional sensors with modified housing can be ordered from our store from these links:
The module has 8 analog inputs 0-10V which can be used also with every analog output sensor within this voltage range. You can check our other sensors as well for the analog inputs: LM35DZ (temperature), LM335Z(temperature), HIH-4000 (humidity), TSL250R(light), GP2Y0A21YK (Proximity), Voltage Transducer 0-300V AC In, 0-10V DC Out, Current Transducer 0-50A AC In, 0-10V DC Out, Wind Speed sensors, Wind Direction sensors and any other analog sensor which can produce analog voltage 0-10V.
The digital inputs can be used with any NO/NC or PNP output sensor like PIR, BEAM, BARRIER, GAS, SHOCK, SMOKE, VIBRATION, ACCESS CONTROL TERMINALS and so on...
Voltage supply output for sensors
smartDEN-Notifier has bilt-in supply out for sensors, so you don't need to care about external power supply for your project. It is possible to take 5VDC and 12/24VDC supply voltage from the module.
Access smartDEN Notifier via web browser
smartDEN-Notifier has built-in web server so all the parameters can be configured from regular web browser. It is possible also to monitor the input values as well.

Access via software DRMv3
This device is supported by DRMv3 Software.
The device can be found in the device list under the default name: smartDEN Notifier-XML or smartDEN Notifier-MQTT
Access smartDEN Notifier via XML/JSON GET Requests
For software integrators - as usually, the module supports HTTP GET requests with JSON/XML reply.

Sample JSON GET request:
Sample XML GET request:
Please refer to the documentation for more information what is the command format and what parameters are supported.
XML and JSON GET request / reply
Access smartDEN Notifier via MQTT Protocol
MQTT (Message Queue Telemetry Transport or also called Machine To Machine or Machine2Machine) protocol is very popular one used widely especially for IoT applications. smartDEN Notifier supports that protocol and this brings one more convient way for integration in third parity systems.
Of course an MQTT broker is required for that, but fortunately Nowadaysthere are lot of free public brokers like:
The module can publish its inputs states periodically or upon event triggered. It is also possible to request the inputs states only via request (poll). For more information please refer to the module technical documentation.
Nowadays, there are lot of MQTT applications available. For example one such software app, ready to be used for monitroing the smartDEN Notifier inputs is the MQTT Spy, which is very useful for when you need to debug the mqtt payloads (messages) sent by the smartDEN Notifier.

Another useful testing tool for iOS is MQTT Probe

Please note notifications are not accessible from Node-RED but only the inputs.
Access smartDEN Notifier via Android App DAE-aModules
Android App DAE-aModules
It is possible to control the smartDEN Notifier via two ways with DAE-aModules - via MQTT protocol (you have to select smartDEN Notifier - Cloud and you will need MQTT broker) and via GET requests (selecting smartDEN Notifier - XML).
Useful information about DAE-aModules and smartDEN Notifier:
- In case smartDEN Notifier - Cloud is selected:
- MQTT Server - this is the MQTT broker IP address or DNS name (for example iot.eclispe.org);
- MQTT Server Port - the MQTT broker port (usually 1883);
- MAC Address - the MAC address of smartDEN Notifier;
- User Name - the username used for connection (see it from "MQTT Settings" page from web server);
- Password - the password used for connection (see it from "MQTT Settings" page from web server);
- In case smartDEN Notifier - XML is selected:
- IP address (URL) - the IP address of the smartDEN Notifier;
- Web Server Port - the web server port of the smartDEN Notifier;
- Password - the web password (can be found in "General Settings" page);
Receiving MQTT Notifications
These are also so called "Push Notifications". They can be published by the smartDEN Notifier periodically or when some event occures.
SmartDEN Notifier sending notifications concept.
Notifications can be easily received via any adroid phone using our DAE-aModule free android app:
Receiving push notifications with DAE-aModules
MQTT or HTTP GET Requests
MQTT (cloud communication) can be used when you don't want to make Port-Forwarding and you need to receive notifications. However you need MQTT broker and internet connection (unless there is locally installed MQTT broker).
HTTP GET Requests communication can be used when you don't want to use cloud service and you want to control the device directly. However notifications at this stage are disabled and it may be necessary to make Port-Forwarding.
Receiving eMail Notifications
The module is able to send eMail alerts (notifications) to one email address upon event generated by some of the analog, digital or temperature inputs. Just put your eMail address into the device eMail settings page and start receiving notifications immediately. Please note SSL is not supported. The supported SMTP protocol is PLAIN AUTH.
SmartDEN Notifier supports SMTP (eMail) alerts (notifications) upon event.
