Control Your Smart Home from Your Wear OS Watch
Now, Android users can sync and control eWeLink-supported devices and manual scenes directly from their Wear OS watches.
After pairing your smartwatch via Profile > Wear OS Watches in the eWeLink App, you can conveniently sync and control your devices and scenes.
Once connected, you can:
- View and control devices like switches, lights, and more.
- Trigger manual scenes with a single tap.
- See real-time updates as device states change.
Example: While getting ready for bed, you can tap the “Good Night” scene on your watch — instantly turning off all lights and closing the curtains, all without reaching for your phone.

Smarter Automations with State Duration Conditions
Create intelligent automations that trigger only when a device stays on or off for a specific duration. This new logic is perfect for energy savings, appliance monitoring, and convenience, and it now supports popular devices like switches and power monitoring plugs.
How It Works:
- Set a time range (1 second to 2 hours, 59 minutes, 59 seconds) for supported devices.
- The automation only runs if the device state (“On” or “Off”) remains unchanged for the entire duration.
- Works reliably even if the device goes offline.
Practical Examples for Everyday Life:
- Energy-saving reminder – if the living room light stays on for more than two hours, send a push notification or turn it off automatically.
- Smart comfort control – if the heater remains on for over three hours, turn it off automatically to prevent overheating or energy waste.
- Ventilation automation – Set bathroom exhaust fans to automatically turn off after running continuously for 30 minutes.
