⚡ SONOFF MINI PM — Zigbee Energy Meter (MINI-ZB1GP)

See exactly where your power goes. The MINI PM is a compact Zigbee 3.0 energy meter that measures real-time power, voltage, current and consumption on any circuit up to 16A — perfect for tracking a geyser, pool pump, or your solar / inverter generation. Live charts, history and exportable data in the eWeLink app, plus electricity-cost reports with time-of-use tariffs. Monitor-only — it does not switch devices on or off. Zigbee hub required. MPN: MINI-ZB1GP.

Zigbee 3.0

Hub Required

⚠️ Monitor only — no switching. The MINI PM measures energy; it cannot turn devices on or off. If you need to switch and meter a load, choose the BASIC-ZB1GSP (switch + power meter) or a POW-series switch instead. A Zigbee hub is also required (ZB Bridge-P/U, NSPanel Pro, iHost, or ZBDongle-E/P with ZHA / Zigbee2MQTT).

⚡ Key Features

Real-Time Energy Tracking — live power (W), voltage and current, with detailed charts, historical records and exportable data right in the eWeLink app
Solar & Inverter Friendly — monitor consumption or renewable generation, so you can see what your solar setup is producing and what the house is drawing
Real Cost Calculation — supports fixed electricity rates and time-of-use tariffs to produce accurate cost reports, so you know what each circuit actually costs to run
Appliance Status Alerts — recognises the on/off state of connected appliances up to 16A and pings you when a job (washing machine, pool pump cycle) finishes
Safety Protection — set custom overload, overcurrent, overvoltage and undervoltage thresholds and get instant eWeLink notifications when they're exceeded
Zigbee Repeater — mains-powered, so it strengthens and extends your Zigbee mesh network
Local Control — Zigbee 3.0 keeps data and automations running on your local network
Home Assistant Ready — works with ZHA and Zigbee2MQTT via a SONOFF Zigbee dongle

🏠 Perfect For

☀️

Solar & Inverter Monitoring

Track how much your panels generate and how much the house consumes, all in one app. Ideal for keeping an eye on a backup or grid-tied setup.

🔥

Geyser Watching

Your geyser is usually the biggest power user in the house. See exactly what it draws and when, so you can time it around tariffs or solar.

🏊

Pool Pump & Big Loads

Monitor pumps, motors and heavy appliances up to 16A, and get a ping when a cycle finishes so nothing runs longer than it should.

💰

Know Your Real Costs

With fixed or time-of-use tariffs, the MINI PM turns kilowatt-hours into Rands, so you can find the circuits quietly costing you the most.

💡 Monitor vs Switch: The MINI PM is a pure energy meter — great when you only want visibility and alerts. If you also want to remotely turn the load on/off (or automate it), pair it with a switch or step up to the BASIC-ZB1GSP, which switches and meters in one unit.

❓ Frequently Asked Questions

Can it switch my appliances on and off?

No. The MINI PM is a measurement-only device — it reports power, voltage, current and energy but cannot control the load. For switching and metering in one unit, look at the BASIC-ZB1GSP or a POW-series power-metering switch.

Do I need a hub?

Yes. It's a Zigbee 3.0 device — pair it to a SONOFF Zigbee gateway (ZB Bridge-P/U, NSPanel Pro, iHost) or a ZBDongle-E/P running ZHA / Zigbee2MQTT.

Can I monitor my solar generation with it?

Yes. It can track renewable generation as well as consumption, so it's well suited to keeping an eye on a solar or inverter installation alongside your household draw.

Does it handle time-of-use billing?

Yes — you can enter fixed rates or time-of-use tariffs in the app and it will calculate cost reports across the different pricing periods.

Does it work with Home Assistant?

Yes — supported in ZHA and Zigbee2MQTT via a SONOFF Zigbee dongle, exposing all the power and energy metrics locally.

How does it install?

It wires inline on the circuit you want to measure. If you're not comfortable working in a DB board or with mains wiring, please have a qualified electrician install it.
