A monthly subscription is not required for using an OtO. Once you purchase your OtO unit, your OtO will work at no additional cost. App and firmware upgrades are also free.
OtO Solutions are Optional
The OtO device can optionally be used with OtO Solutions which are available for purchase on a subscription basis via our website. You can always use OtO as a water sprinkler only and do not have to use OtO solutions.
