Smart Irrigation.

Water is our most precious resource. A smart irrigation system can help ensure your lawn and garden get enough moisture to be healthy and vibrant without wasting any of it. And of all the smart home subsystems you can invest in, this might be the one that will benefit the least from being incorporated into a hub.

Smart irrigation systems are a combination of an advanced technology of sprinklers with nozzles that improve coverage and irrigation controllers that are watering and water conservation systems that monitor moisture-related conditions on your property and automatically adjust watering to optimal levels.

Smart irrigation technology uses weather data or soil moisture data to determine the irrigation need of the landscape and can also be complex, so using a purpose-built app is usually better anyway.

Let's see the options for this quarter (Q4 2021).
