Monitoring a small world

" summary

Shows concrete paths to get constrained sensors into Zabbix/Icinga/Checkmk: JSON HTTP endpoints for a CO2 board, MQTT broker → Fluentd → Checkmk for larger fleets, and a Prometheus-compatible MicroPython exporter running on ESP-class MCUs. Demonstrates a Checkmk agent on port 6556, a tiny syslog push for events, and using a hardware watchdog that reboots after 10s when sends fail. Covers LoRa/LoRaWAN (records up to 331 km) and tradeoffs with NB‑IoT and when Arduino vs MicroPython libraries actually work.
