Utilize the app’s user-friendly automation functions to create automatic actions per your specific needs. (Products sold separately!)
- No Tricky Wi-Fi Requirements: While many smart devices use and depend on your Wi-Fi network, YoLink devices utilize a proprietary radio frequency spread spectrum technology known as LoRa (Long-Range). With YoLink, you no longer have to worry about your devices consuming your Wi-Fi bandwidth. (YoLink Hub requires a 2.4 GHz Wi-Fi connection or a wired connection to your network equipment (patch cord included).
- Low-Power Means Longer Battery Life: Because of the low power consumption, device batteries may last 2 years or more (depending on application and device usage/activity), on standard AAA Alkaline batteries (lithium batteries not required)!
- Environment Monitoring – Be informed of the current temperature and humidity of critical equipment and rooms, as well as receive instant notifications of changes based on your personalized criteria. Current temperature and humidity is displayed on the YoLink app, along with historical graphs, so you can monitor current and past temperature and humidity conditions.
