Tongou Smart Circuit Breaker - Tuya/Smart Life Compatible

Tongou Smart Circuit Breaker — SmartLife (Tuya) Compatible (63A)

Same concept as the eWeLink version of the Tongou breaker — replaces a breaker in your electrical panel, gives you remote control and live power monitoring — but this one talks to the SmartLife / Tuya app instead of eWeLink, and includes a built-in voltage protector.

The voltage protector matters in Lebanon. When EDL surges or drops, set your safe range (say 180V to 250V) and the breaker trips automatically — protecting your fridge, AC, TV, and anything else expensive plugged in downstream.

Why people buy it specifically

• Already on SmartLife / Tuya? If you have other Tuya devices (some Chinese-brand lights, smart plugs, cameras), this one pairs with the same app — keep everything under one roof.
• Voltage protector built in. Critical in Lebanon — set limits like “trip if voltage goes above 250V or drops below 180V” to shield your fridge, AC, and electronics from EDL spikes.
• Same physical product as the eWeLink version — DIN rail mount, 63A, remote on/off, power monitoring. Just a different app.

Key Features

• Voltage protector — set your own high (max 265V) and low (min 76V) trip thresholds.
• Up to 63A — water heaters, ACs, ovens, solar systems.
• Power monitoring — live W / A / V per circuit with history graphs in SmartLife.
• Overcurrent protection — set your own amperage trip limit.
• Overtemperature protection — trips at 100°C internal temperature.
• Schedules + timers through the SmartLife app.
• DIN rail mount — fits standard electrical panels.
• Voice control — works with Google Assistant and Alexa.
• 2.4 GHz Wi-Fi. No hub needed. Single-phase. Neutral wire required.
• Model: TO-Q-SY2-JWT.

💡 Pro Tip: Use the voltage protector feature on the circuit feeding your fridge and any other expensive electronics. Set “trip below 180V” and “trip above 250V” — when EDL acts up, the breaker cuts the appliance before damage is done. Costs you a fridge once, you’ll wish you had this every time.

⭐ Frequently Asked Questions

What’s the difference between this and the eWeLink version?

Physically identical — same breaker, same 63A rating, same features. Two differences: this one uses the SmartLife / Tuya app instead of eWeLink, and this one adds a voltage protector (the eWeLink version doesn’t have it). Pick this one if you’re already on the SmartLife/Tuya ecosystem or you specifically want voltage protection.

Will it protect my fridge from EDL voltage spikes?

Yes — that’s the whole point. Set a safe voltage range (e.g. 180–250V), and the breaker trips the moment voltage goes outside that range. Your fridge stays disconnected until voltage normalizes.

What voltage range should I set?

For most home appliances, 180V minimum and 250V maximum is a safe range. The breaker physically supports 76V minimum and 265V maximum, but those extremes are wide enough to still damage equipment.

Can I set the amperage at which it trips?

Yes. The SmartLife app lets you set your own current limit. When the load exceeds that, it trips — useful for protecting circuit wiring or specific appliances. (Note: by default the trip current may be set quite low, e.g. 5A. Adjust it for your actual load before relying on it.)

Why does my breaker keep tripping unexpectedly?

Usually not a fault — it’s your protection thresholds set too aggressively. Open the SmartLife app, check the trip current, max temperature, high/low voltage limits. If the trip current is at 5A by default but you’re running a 10A load, that’s why. Raise the limit to match what you actually expect.

Do I need a hub or gateway?

No. It connects directly to your home Wi-Fi (2.4 GHz). The same way your phone connects.

Can I install a water heater on this breaker?

Yes — up to 63A means it easily handles water heaters (typically 10–15A), AC units, ovens, and solar systems.
