Install a weather station
Save money and energy

So you’ve got your smart learning thermostat and a few smart plugs, not to mention flourishing relationships with Alexa and Siri. Great start!...but what about outside?

    Connect to the cloud

    AIR and SKY connect via long range telemetry to an indoor receiving hub. The hub then publishes data to the cloud via your home WiFi network and/or locally to your iOS or Android device via Bluetooth Low Energy. The hub also broadcasts data locally via UDP for direct raw data access. With robust REST APIs and a range of integrations including IFTTT, it's simple to configure automated smart home actions.
