Each environment satellite held a full meshtastic_EnvironmentMetrics, 304 B for 38 optional fields, of which a real sensor sets a handful. At the nRF52 cap of 40 that is ~12 KB of heap holding about 1 KB of data. Store the encoded bytes instead (~15-40 B per entry) and decode on read: copyNodeEnvironment() keeps its signature. The save writes the stored bytes straight out as the entry's environment_metrics, so nodes.proto is unchanged; the load packs each decoded entry. hasNodeEnvironment() becomes a key lookup, and MemAudit counts the real blob sizes.

Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
