Hilscher and SIGNL4 Mobile Alerting
I have connected a sensorEDGE FIELD – Edge IO-Link Master from Hilscher with SIGNL4. The edge device is powerful enough to run Docker containers, enabling it to host services such as an Eclipse Mosquitto MQTT broker and Node-RED directly on the device, and even additional applications if required.
The connected sensors publish their data to the MQTT broker. From there, Node-RED subscribes to the data, processes it, and evaluates defined conditions. If certain thresholds are exceeded (for example, if the temperature is too high), a SIGNL4 alert is automatically triggered.
This setup makes bridging the OT/IT gap straightforward and enables reliable mobile alerting in various IIoT scenarios.
