Smart Life runs devices from dozens of shop brands. Set up the account, rooms and routines in the right order and the app stays manageable as the house grows.

Tuya is the platform inside many of the plugs, bulbs, switches and sensors sold on Shopee and Lazada under many brand names, and Smart Life is its own app for running them. A tidy Smart Life set-up comes down to structure: one account owned by the household, one home with real rooms, a Zigbee gateway added before any Zigbee device, and a clear split between Tap-to-Run scenes and Automations. Get that right and fifty devices stay manageable. For the bigger picture, see smart home installation.
Tuya describes Smart Life as an all-in-one app: a device maker builds the hardware, and Tuya supplies the app and the cloud behind it. The maker can simply print a QR code for the app in the product manual. That is why a plug from one shop brand and a curtain motor from another can end up side by side in the same app. Tuya says the app handles WiFi, Bluetooth and Zigbee devices.
Some brands ship their own app built on the same platform instead. If the box points you to a brand app, check whether the manual also lists Smart Life; running everything in one app is much easier than juggling three. If you have not chosen a platform yet, the Tuya versus eWeLink comparison helps with that decision.
Sign up with the email or mobile number of the person who owns the property, not the person who happens to be holding the phone on installation day. Every device you add is tied to this account. The manual's account page shows the account's region, so pick the correct country at sign-up rather than accepting whatever the phone suggests.
Next, under Me and Home Management, create the home and set its location. The app uses that location for weather and sunrise conditions later, so put in the real address area. One house is one home; a landlord with several units should create one home per unit.
Home Management is also where you invite household members. Members see and control the home's devices under their own login, and the manual describes making a member an administrator. Give administrator rights to two adults, so the house does not depend on one phone. A domestic helper or a tenant is usually better off with a single shared device than full membership.
| Who | Suggested access | Why |
|---|---|---|
| Owner | Account holder | Devices are tied to this account |
| Spouse or second adult | Member set as administrator | Can add devices and fix things if the owner is away |
| Older children, parents | Member | Control and scenes without editing the set-up |
| Helper, guest, tenant | One shared device via Share Device | Access to what they need, nothing more |
Build the room list before you add anything. The app offers default room names and lets you add your own, so match them to how the family talks: “Master”, “Kids”, “Kitchen”, “Porch”. When each device is added, put it straight into its room and give it a name that says what it does. Voice assistants use these names, so “Porch light” beats “Smart Switch 2”.
The manual describes an automatic scan that finds WiFi devices, Bluetooth devices and Zigbee gateways together, which needs the app to have WiFi and Bluetooth permission on the phone. Zigbee sensors and switches are different: the manual says a gateway must be added before Zigbee devices are added, and once a gateway is in, its sub-devices are paired through it.
WiFi devices only join a 2.4 GHz network, according to the manual. If your router uses one name for both bands, the app's compatibility mode (AP mode) is the usual way through; Tuya's own FAQ also warns against router names written in Chinese characters and against MAC filtering. When pairing still fails, our WiFi 2.4 GHz pairing guide walks through band steering and router settings step by step.
A home with a few plugs can run on WiFi alone. Once you are past a dozen devices, or you want battery door sensors and wireless buttons, a Zigbee gateway takes the load off the router. Put it in the middle of the house on a stable power point, cabled to the router if it has an Ethernet port. Our protocol explainer covers the radio side.
Smart Life splits routines into two kinds, and mixing them up is the most common reason a “smart” home still needs someone to press things.
| Tap-to-Run | Automation | |
|---|---|---|
| Starts when | Someone taps it, or a voice command calls it | A condition you set becomes true |
| Good for | “Movie night”, “All off” before bed | Porch light at sunset, alert on a leak sensor |
| Effective Period | Not available | Can be limited to certain hours or days |
| Can call the other | Yes, a scene can run several tasks | Yes, an automation can run a Tap-to-Run scene |
The manual lists the condition types an automation can use: a change in the weather, a change in your location, a schedule, a device changing state, and sunrise or sunset. Tasks can run a device, run another scene, send a notification, or wait before the next action.
| Condition type | Example | Watch out for |
|---|---|---|
| Sunrise or sunset | Porch and gate lights on at sunset, off at a set hour | Set the home location correctly |
| Schedule | Bedroom fan or desk lamp plug off at a set hour | Check the plug's rating suits the load |
| Device status | Bathroom fan on when a humidity sensor reads high | The sensor must sit in the room it measures |
| Weather | Close the balcony blind when rain is forecast | Forecasts are for the area, not your balcony |
| Location | Lights on as your phone arrives home | Phone location can lag; avoid it for anything security related |
Location-based automations depend on the internet and the phone, so do not use them for anything that must always happen. If a rule fires late or not at all, the automation troubleshooting guide lists the usual causes.
Share Device on a device's page gives another account access to that one device without making them a member of the home. That suits a helper who needs the gate or a parent who needs one aircon.
Under Me, Third-Party Integration links the account to voice assistants. Link once, then say “discover devices” in the assistant after each new device. Our guide to Google, Alexa and Siri helps pick one.
For alerts, the manual lists the in-app Message Center plus Message Notification and Phone Notification channels, and the last two are subscription services. In-app push alerts are enough for most homes; decide before an emergency whether you need more.
Each device has a Device Information page showing its device ID, IP address and MAC address. Note these down for anything important: if your router has a client list or a device limit, the MAC address is how you recognise the plug among forty gadgets. Check for firmware updates from the device page now and then, especially after a device starts misbehaving.
Keep smart devices separate from the family laptops if your router allows it; the IoT network security guide shows how to do that without breaking the app. When you move house or change routers, remove devices from the app before handing them over, so the next owner can add them to their own account.
Tuya-based wall switches come in with-neutral and no-neutral versions, and the switch box decides which one works; the no-neutral smart switch guide explains the difference. Changing a wall switch is electrical work. For smart switches and anything wired into the mains, we supply the devices and set up the app, and the switch or wiring work is done by an electrical contractor registered with Suruhanjaya Tenaga that we coordinate.
We set up the Smart Life account in your name, build the homes and rooms, pair the gateway, plugs, sensors and IR blasters, and write the first scenes and automations with you. We do the smart device, app and low-voltage side of the job. Any mains electrical work, such as a new power point, a change at the distribution board or a hardwired switch that needs new wiring, must be done by an electrical contractor registered with Suruhanjaya Tenaga.
