EnergyFleet reference stack

Bench test

Primary path (P1 AVH + 4G DTU): bench tested. Other profiles (P2–P4): pending. Tracker: Validation status.

Fleet dashboard for 3-phase energy meters. Device type: energy_meter.

Dashboard spine: Solution dashboard template.

Telemetry contract

Keys consumed by EnergyFleet widgets (align published telemetry to these names):

Key	Typical unit	Source (AVH-14-M1 manual)
active_power_kw_total, active_power_kw_l1…l3	kW	Per-phase and total active power
voltage_l1n … voltage_l3n, voltage_l12 …	V	L–N / L–L
current_l1 … current_l3, current_avg	A	Phase current
frequency_hz	Hz	45–60 Hz band per meter spec
power_factor_avg, power_factor_l1…	—	0.1–1.0
energy_kwh_int, energy_kwh_frac	kWh	Integer + fraction pair per AVH note
md_kw, load_hours	kW, h	Demand / run hours

Sample generators and alarms in Autoconnecto use field-realistic bands derived from the AVH-14-M1 Modbus map.

Step	Action
1	Install meter + CT/VT per AVH-14-M1 terminal diagram (mains work)
2	RS485 A/B to DTU; baud 9600 8N1 (match meter menu)
3	Create energygateway + child avh1 with AVH register map (see device guide)
4	Configure DTU MQTT topics with gateway token

Wiring — P2 (ESP32 WiFi at panel)

Same RS485 to AVH; ESP32 replaces DTU for MQTT uplink on WiFi. Reuse register addresses from AVH device guide.

Autoconnecto checklist

• [ ] Create gateway + child devices linked with parentDeviceId (Sample On demos this topology)
• [ ] Child device type energy_meter
• [ ] Modbus map matches AVH float CDAB addresses
• [ ] Telemetry visible on child device, not only gateway
• [ ] Optional hub health: publish gateway.heartbeat on the gateway token (no childDeviceId)
• [ ] Gateway shows Active from hub heartbeat and/or any active child
• [ ] Device retarget: dashboard EnergyFleet, state detail
