63 A WiFi relay with metering and protections
Tongou TO-Q-SY2-JWT is a WiFi DIN rail relay that measures voltage, current, power and energy consumed, and protects a circuit with a current of up to 63 A. You set the overcurrent protection threshold in the Tuya Smart or Smart Life app in the range of 1 A to 63 A, and the relay also reacts to voltage that is too high or too low, excessive power and high temperature.
For each protection, you choose whether the relay should only send an alarm or disconnect the circuit. The L pole is switched, the N pole is a pass-through, and the button on the housing lets you switch the circuit on without a phone. The same relay in a ZigBee version is the TO-Q-SY2-JZT, and metering without a relay is provided by the TO-Q-SA1 WiFi meter with a current transformer.

Is it the right choice for you?
A good choice if:
- you want to remotely control an entire circuit in the switchboard
- you want to check the circuit's energy consumption on your phone
- you need an alarm for voltage that is too high or too low
Consider another option if:
- you have a ZigBee-based system: choose the TO-Q-SY2-JZT version
- you only want to measure a circuit without a relay: choose the TO-Q-SA1 meter
Fun fact
Chayo or Tongou? The same brand
The relay housing may carry the Chayo logo instead of Tongou. The manufacturer explains that both trademarks registered in the EU belong to Changyou Technology (Zhejiang), and the logo change affects neither the product parameters nor after-sales support.

Frequently asked questions
How do I set the tripping current?
In the app, you set the overcurrent threshold from 1 A to 63 A and choose whether the relay should send an alarm or disconnect the circuit. The protection responds after 5 s.
Can I block remote switch-on?
Yes. Service mode set in the app blocks remote switch-on, e.g. while work is being done on the circuit. You exit it by pressing the button on the housing 4 times in a row.
Is there a ZigBee version?
Yes. The same relay with ZigBee 3.0 connectivity is the TO-Q-SY2-JZT model, which according to the manufacturer also works with Home Assistant and Zigbee2MQTT.
