• With the eWeLink app, you can view temperature and humidity data by day, month, or up to the last six months, with a storage capacity of up to 180 days. You can access or export historical data, which helps you better understand your garden and optimize plant care. Create smart scenes through the eWeLink app, receive notifications for abnormal activity, or set up automation based on temperature or humidity changes. For example, you can receive instant notifications on your phone if a power outage causes a sudden temperature drop in your reptile tank. When the air becomes too dry, you can automatically activate the water valve for irrigation to maintain optimal garden humidity.
