" Due to the increased costs associated with maintaining the Skydrop Cloud, including the hyper-local weather data, it has become necessary for Skydrop to implement a monthly service fee. Beginning in the first part of June 2019, you will see some changes to Skydrop Web and Skydrop Mobile. These changes will include a limit to the functionality to manage and monitor your Skydrop Controller. You will still be able to see very basic information about your controller but changing the watering restrictions, watering schedule, adjusting zones and running zones manually will be disabled. Within Skydrop Mobile, you will see an option to upgrade to Skydrop Plus. Skydrop Plus includes not only the functionality to manage your controller, but also advanced reporting, more precise weather data, enhanced notifications, and more.
The Skydrop Plus subscription will cost $1.99/month (USD) or $17.99/year (USD) and will be billed through the Apple App Store or Google Play Store. If when prompted to upgrade to Skydrop Plus, you see a higher price, please ensure you have the latest version of Skydrop Mobile.
We understand this cost is unexpected after purchasing your Skydrop controller. We
hope you agree that this cost is small relative to the savings and benefits that
Skydrop provides through the Smart Watering algorithm as well as the ease of use
of an app-enabled sprinkler controller.
We know you may have questions. We’ve tried to anticipate most of them in the FAQ below, but if you have additional questions, feel free to reach out to our customer support team at email@example.com. We are grateful for your patience as we work through this transition. We will respond to you as quickly as possible.
