Generated from the facts file of the release this site was built from; an item shows as live only once its acceptance run passed.
Through a server inside the install.
The tracker server, the LoRaWAN network server and the NB-IoT server ship in the install as options, switched on only where you choose them. Your devices talk to them through ports your IT opens; they hand every reading to the pipeline.
Straight to HOLOIN.
Anything that can push — an MQTT publish, an HTTP or CoAP post, a Sparkplug edge node, a charger over OCPP, your monitoring’s alerts — sends to the app itself, with a token per source. A field map places any JSON by path.
Through the Field Agent.
Controllers and meters on your OT network — BACnet, Modbus, OPC UA, KNX in beta, SNMP, SunSpec — are read by the Field Agent, which runs beside them and only ever connects outward, to your HOLOIN. The agent opens no listening port.
