The owner can share the devices to other eWeLink accounts. Please make sure both account owners keep the eWeLink app to the front and login with a stable network.
Here is a step-by-step instruction for the share control.
1. Click Share.
2. Enter the eWeLink account (phone number or email address according to the country) you want to share. Please tick the timer permissions (edit/delete/change/enable) you want to give, then click OK.
3. The other account will receive an invitation message. After the account owner click Accept, the device has shared successfully. The other user will have access to control the device, and you'll see the result as below.
Please kindly note that the account you shared to have to been registered to the same server, that is both to EU server or both to US server, or the share control will not work.
