Measurement & Memory

Sensors & Data

Home Assistant, MQTT, ESPHome, environmental sensors, dashboards, photographs, and the local computers that preserve observations.

A sensor reading becomes useful when its context is preserved.

Collection

Field instruments

Water level, soil moisture, temperature, motion, weather, battery state, and future measurements.

Movement

MQTT and the local network

Readings travel through serial links, ESP32 devices, Ethernet, Wi-Fi, PoE, and message brokers.

Display

Home Assistant

Current states, histories, alerts, and comparisons can become evidence for later reports.

Memory

Immich and the workbook

Photographs retain visual context while the workbook preserves meaning, uncertainty, and revision history.
