One gateway, many sensors
Every sensor in the family reports to the same gateway. A typical plant uses one to three receivers, placed at scoping, not one per machine.
TB-G01. One gateway for every TrackBeat sensor on the site. Every sensor on the floor reports to it. It keeps a local dashboard and a local UI on the wall, and it opens one outbound TLS connection. Diagnosis stays in the cloud.

The local dashboard and local UI run on the device. When the wide-area link drops, the wall display stays up.
Sensors arrive over sub-GHz. The receiver publishes outbound over MQTT with TLS, over Wi-Fi, Ethernet or LTE. The plant firewall does not gain an inbound rule.
A relay. The diagnosis stays in the cloud.
