Modules to Exclude — Moire Sensor Node (Heltec T114)

For maximum battery life on the moisture-sensing node, which wakes, reads, transmits, and sleeps.

Exclusions Ranked by Impact

Module	Reason	Impact
EXCLUDE_GPS	T114 has an L76K GPS polled periodically — biggest single win for a static sensor node	High
EXCLUDE_NEIGHBORINFO	Periodically broadcasts neighbor packets — radio TX is expensive	High
EXCLUDE_EXTERNALNOTIFICATION	Has a polling runOnce thread	Medium
EXCLUDE_TRACEROUTE	Responds to trace packets, minor CPU wake overhead	Medium
EXCLUDE_DETECTIONSENSOR	Has its own polling thread; MoireSensorModule replaces this role	Medium
EXCLUDE_ATAK	Not needed on a sensor node	Low
EXCLUDE_CANNEDMESSAGES	UI feature, not needed	Low
EXCLUDE_REPLYBOT	Not needed	Low
EXCLUDE_WAYPOINT	Not needed	Low
EXCLUDE_REMOTEHARDWARE	Not needed	Low
EXCLUDE_RANGETEST	Testing only	Low
EXCLUDE_SERIAL	Not needed if not using the serial data module	Low
EXCLUDE_PKI	Saves RAM/flash; only exclude if not using encrypted channels	Low
EXCLUDE_POWERSTRESS	Testing-only module	Trivial
EXCLUDE_DROPZONE	Not needed	Trivial
EXCLUDE_STATUS	Not needed	Trivial

Modules to Keep

Module	Reason
ADMIN	Required for over-mesh reconfiguration
NODEINFO	Required for mesh participation
TEXTMESSAGE	Core mesh packet handling
ENVIRONMENTAL_SENSOR / HAS_TELEMETRY	Sensor data pipeline
GENERIC_THREAD_MODULE	May be required by MoireWakeupModule

Note on GPS Hardware

EXCLUDE_GPS removes the firmware module only. The L76K GPS on the T114 is powered via VEXT_ENABLE (pin 21). The existing T114 variant power management already handles keeping this pin low during sleep, so hardware power-down should be covered automatically.
