APEX #6 — Open Apexpress: the whole series in a few clicks
Five episodes of hand-writing JSON and haggling with the OPA? End of the ECLYPSE APEX series: Open Apexpress, a single .exe that installs Mosquitto, Zigbee2MQTT, ChirpStack, Node-RED, Grafana and friends on the controller, through the official REST API.

APEX #5 — ChirpStack: a LoRaWAN server in the cabinet (and a feeling of déjà vu)
No subscription, no cloud: a complete LoRaWAN network server inside the controller. Fifth episode of the ECLYPSE APEX series: now that you get the principle, it's always the same thing. Or almost: distroless images have a small catch.

APEX #4 — MQTT, Node-RED, REST API: the controller that watched the fish go by
Your ECLYPSE can publish over MQTT but can't listen. Node-RED listens for it, the REST API does the dirty work, and MQTT becomes real BACnet points. Not a tutorial: what we built, what holds up, and the traps. Flow to download, link to Sylvain Montagny's work.
