What is the Tuya/SmartLife smart home platform and app?

Tuya is a popular cloud-based smart home platform that offers integrated solutions for a variety of smart home devices and applications. The platform makes it quick and easy to connect devices, remotely control and manage them through a single app. Known as Tuya and SmartLife, it offers users a complete smart home ecosystem with products from a wide range of manufacturers.

It supports voice control, remote access and automated processes (scenes). Tuya's cloud integration extends to other smart home ecosystems such as Amazon Alexa, Google Assistant and SmartThings, allowing Tuya devices to be used on these platforms as well. Similar to the global eWeLink platform, Tuya is also cloud-based, although the quality of Tuya devices varies more.

In the Tuya range, the European brand Nous offers stable, high-quality Tuya devices that can be used with the Nous app as well as the standard Tuya app.


Nous B1Z Tuya Zigbee smart relay module is a 1-channel smart relay module. It supports 100-240V AC, 24-48V DC or 12V DC power supply. Its special feature is the possibility of single-channel power metering, which allows to measure the power consumption of monitored devices and to manage them based on the power consumption data.

With the built-in Tuya Zigbee chip, it can connect to Nous' own Zigbee gateway or other standard Tuya Zigbee gateways. The device is suitable for control via smartphone with the Nous app, but experience shows that it provides more functionality when using the Tuya app.

Due to its small size, the module fits into the standard depth of recessed dosing units for traditional switching points. It has a switch input so that "smart upgraded" switch points can continue to operate as before.


The Nous B1Z module is designed for the Tuya smart home, which operates primarily in cloud mode. However, with Tuya Zigbee gateways supporting local caching and running automations without an internet connection, automations can also run offline.

When connected to the Tuya Zigbee gateway, it supports voice control via Amazon Alexa, Google Assistant and (for iOS phones) Siri.


Main features:

  • Connection via Tuya Zigbee chip: connects to Tuya Zigbee gateways via 2.4 GHz Tuya Zigbee protocol.
