The all-new Prime Plan takes the Advanced membership a step further, offering enhanced device control, higher sharing limits, and exclusive tools designed for power users.

Prime Plan Highlights
- Everything in the Advanced Plan, plus:
- Control eWeLink-supported devices and manual scenes directly from your Wear OS Android Watch.

Prime subscriptions are available in the eWeLink App (V5.21). Web subscriptions will launch later in December.
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.
Expanded Android Widget Support
Android users can now add Device Control and Sensor View widgets for a broader range of devices.
From checking your room temperature to turning on your heater with a single tap, widgets make your smart home faster and more accessible — right from the home screen.
