Telemetry contract

Key	Unit	Notes
soil_moisture_pct	%	Volumetric / capacitive probe
flow_rate	L/min	Zone supply flow
valve_open	boolean	Solenoid / latching valve feedback
rainfall_mm	mm	24h rain gauge

---

Reference hardware (pending bench test)

Role	Class / example	Protocol
Soil	Capacitive moisture (RS485 Modbus or analog)	Modbus / ADC
Flow	Pulse or EM flow meter	Pulse → edge, or Modbus
Valve	12/24 V solenoid + feedback contact	GPIO / DI
Rain	Tipping-bucket rain gauge	Pulse
Controller	Hunter / Rain Bird class with MQTT gateway	P4

Status: Pending bench test — valve control (write) is out of scope for fleet home; monitoring first.
