🔌 SONOFF BASIC-ZB1GSP — Zigbee Smart Switch + Energy Meter

Switch it and measure it. The BASIC-ZB1GSP is a single-channel Zigbee 3.0 smart switch with built-in power metering — control a load on/off while tracking real-time power, voltage, current and energy, with full consumption history. Adds inching (momentary) mode, configurable overload protection, and a power-on state for clean load-shedding recovery. Zigbee hub required. MPN: BASIC-ZB1GSP.

Zigbee 3.0

Hub Required

⚠️ Zigbee hub required. No WiFi — pair it to a SONOFF Zigbee gateway (ZB Bridge-P/U, NSPanel Pro, iHost) or a ZBDongle-E/P running ZHA / Zigbee2MQTT. This is an inline DIY switch that wires into your circuit — if you're not confident with mains wiring, have a qualified electrician install it.

⚡ Key Features

Switch AND Meter in One — remotely turn a load on/off while seeing live power, voltage, current and energy; no separate meter needed
Full Energy History — today, yesterday, this month and total consumption, with detailed records you can read back and clear when needed
Inching / Momentary Mode — pulse the relay for a set time (great for triggering a gate or garage motor, then auto-releasing)
Configurable Overload Protection — set maximum current, voltage and power thresholds; the switch alerts and protects when they're exceeded
Power-On State — choose On, Off or Last State after an outage for predictable load-shedding recovery
Local Zigbee Control — Zigbee 3.0 keeps switching and automations running on your local network, with mesh-repeater function (mains powered)
Home Assistant Ready — confirmed support in Zigbee2MQTT and ZHA for full local control of switching and metering
eWeLink App — schedules, smart scenes and notifications on iOS & Android

🏠 Perfect For

🔥

Geyser Control + Metering

Switch your geyser on a schedule (or around solar) and see exactly what it consumes — control and visibility in a single device.

🏊

Pool Pump

Run the pump on a timer and track its energy draw, with overload alerts if something goes wrong on the circuit.

🚪

Gate / Garage Trigger

Inching mode pulses the relay briefly, making it ideal for momentary triggers like gate and garage-door motors.

📊

Any Switch-and-Measure Load

Anywhere you want to both control a circuit and know its consumption — appliances, lights, workshop tools and more.

💡 Switch + Meter vs Meter-only: The BASIC-ZB1GSP both controls and measures a load. If you only need monitoring (no switching), the MINI PM (MINI-ZB1GP) is a more affordable monitor-only option.

★ Before you publish: confirm the exact max load (A), input voltage and dimensions against the retail box / SONOFF spec sheet and fill them into the table below — these vary by SKU and we haven't hard-confirmed them for this model.

❓ Frequently Asked Questions

Does it switch AND measure energy?

Yes — both. Unlike a meter-only device, the BASIC-ZB1GSP turns the load on/off and reports live power, voltage, current and full energy history.

Do I need a hub?

Yes. It's Zigbee 3.0 with no WiFi — pair it to a SONOFF Zigbee gateway (ZB Bridge-P/U, NSPanel Pro, iHost) or a ZBDongle-E/P running ZHA / Zigbee2MQTT.

Does it work with Home Assistant?

Yes — it's a supported device in Zigbee2MQTT and ZHA, exposing the switch plus power, current, voltage and energy readings for full local control and automation.

What is inching / momentary mode?

Inching makes the relay switch on then automatically off again after a set time (e.g. half a second). It's ideal for momentary triggers like gate and garage-door motors, rather than holding a circuit permanently on.

What happens after load shedding?

Set the power-on state to On, Off or Last State. When power returns, the switch restores to your chosen state — handy for getting a geyser or pump back to where you want it automatically.

How does it install?

It's an inline DIY switch that wires into the circuit (live in/out, plus neutral). If you're not comfortable working with mains wiring, please use a qualified electrician.
