Tongou Smart Circuit Breaker – Sonoff/eWeLink Compatible

Tongou Smart Circuit Breaker — eWeLink Compatible (63A)

This replaces an existing breaker in your electrical panel, so you can switch any circuit on or off from your phone — and see exactly how much electricity each one uses. Built-in leakage protection and overload trip keep things safe. The eWeLink app is the same one your Sonoff devices use, so everything ends up under one roof.

Made for high-power loads like water heaters, AC units, electric ovens, and solar systems.

Why people buy it

• Schedule the water heater. Heat water for 30 min before you wake up and 30 min before showers — stop paying to heat water all day for nothing.
• Cut breakers from anywhere. Forgot to turn off the AC at the village house? Tap the app from Beirut.
• See your real consumption. Live W / A / V per circuit — find what’s actually running up your bill.
• Survives EDL cuts. Set “Last State” in the app: when power comes back, the circuit returns to exactly where it was.
• Family sharing. Add a second eWeLink account so the whole household can control circuits without sharing your login.

Key Features

• Up to 63A — water heaters, ACs, ovens, solar systems.
• Power monitoring — live W / A / V per circuit, history graphs in the app.
• Leakage + overload protection — trips automatically on electrical leak or overcurrent.
• Set your own current limit — choose the amperage at which the breaker should trip.
• DIN rail mount — fits standard electrical panels.
• Voice control — works with Google Assistant and Alexa.
• 2.4 GHz Wi-Fi. Single-phase. Neutral wire required.

💡 Pro Tip: Install this on your water heater circuit and schedule it: 30 min before the morning shower and 30 min before evening showers. You stop heating water for 24 hours straight, every day, for nothing.

Installation

• Requires a neutral wire at the breaker location — most modern Lebanese panels have one; older houses may not.
• Fits any standard DIN rail panel — the same shape as the breaker it replaces.
• Basic electrical knowledge needed. If you’re not comfortable opening the panel, any electrician can handle it in 10 minutes.

⭐ Frequently Asked Questions

Does it work with the eWeLink app I already use for Sonoff?

Yes — that’s the whole point. It’s officially eWeLink-compatible and gets added the same way as your Sonoff devices. It does NOT work with Smart Life / Tuya — make sure to pick the eWeLink version.

What happens when EDL cuts and comes back?

Open the device settings in eWeLink, scroll to “Power-on State” and set it to “Last State”. When EDL returns, the circuit goes back to exactly the on/off state it was in before. Wi-Fi reconnects automatically once your router is back.

Can it handle my water heater / AC / oven?

Yes. The breaker is rated up to 63A — a typical water heater draws 10–15A, an AC unit 6–12A, an oven 15–20A. All well within range. Works for solar systems and sewage pumps too.

Do I need an electrician to install it?

You need basic electrical knowledge: turn off the main, swap the breaker, mount on DIN rail, connect Live and Neutral. If that sounds fine, you can do it yourself. If not, any electrician can handle it in 10 minutes.

Can the whole family control it, or just one person?

You can share access with a second eWeLink account — so the whole household can control circuits without anyone sharing logins.

Can I set a custom amperage so it trips at a specific limit?

Yes. The eWeLink app lets you set your own current limit. When usage crosses that line, the breaker trips automatically — useful for protecting older wiring or expensive appliances.

What if I want to remove it later?

It swaps back to a normal breaker exactly the way it went in. Standard DIN rail, single-pole, mono-phase — no special hardware needed.
