Multiple devices? Meet the AEM-Hub
A gateway that concentrates up to 31 AEM devices on the RS485 bus and pushes everything to the cloud over MQTT — no PC in the panel.
LRI-AEM-HUB
Concentrates up to 31 AEMs on the same RS485 bus and publishes everything over MQTT.
Built-in Ethernet and Wi-Fi — no dedicated PC or PLC needed in the panel.
Local buffer: without internet, data is stored and synced later.
Same LRI Monitor app as Utility Pro, with all sites in one account.
