ZigBee 63 A relay for Home Assistant and Tuya
Tongou TO-Q-SY2-JZT is a ZigBee 3.0 DIN rail relay that reports the circuit's voltage, current, power and energy through Zigbee2MQTT or the Tuya app. The manufacturer states support for Home Assistant and Zigbee2MQTT, so you can use the measurements and relay state in your own automations, e.g. to switch off loads at high power consumption.
The relay connects through a ZigBee gateway, e.g. SMLIGHT SLZB-06mg24. You can set the overcurrent threshold from 1 A to 63 A, and the voltage, power and temperature protections will send an alarm or disconnect the circuit. If you do not have a gateway, choose the WiFi version TO-Q-SY2-JWT with the same parameters.

Is it right for you?
Good choice if:
- you use Home Assistant with Zigbee2MQTT and want to measure a circuit
- you are expanding a ZigBee network and already have a gateway
- you want to disconnect a circuit at too low a voltage
Consider another option if:
- you do not have a ZigBee gateway: choose the WiFi version TO-Q-SY2-JWT
Fun fact
Five protections in one module
The TO-Q-SY2 relay has five protections: overcurrent, overvoltage, undervoltage, excess power and temperature. For each one you choose the operating mode: off, alarm only or circuit disconnection, and the reaction occurs after 5 s.
Frequently asked questions
Does it work with Home Assistant?
Yes. The manufacturer states support for Home Assistant and Zigbee2MQTT. You need a ZigBee coordinator connected to Home Assistant.
What power threshold can I set?
You can set the excess power protection from 1 kW to 26 kW. When the threshold is exceeded, the relay will send an alarm or disconnect the circuit.
What does the red button mean?
A button lit red means that the relay is on. The blue LED is steady after connecting to the network and blinks in pairing mode.
