Rachio Allows Users to Control and Monitor Home Irrigation Using PubNub

rachioRachio is a smart irrigation platform that includes a controller, iOS and Android smartphone app, and web-based dashboard. The platform adjusts for weather and waters only when needed, and enables users to control and monitor their yard in realtime from the smartphone app or dashboard. The controller, the Rachio Iro, acts as a hub and connects to the smartphone or web app to the irrigation hardware, allowing users to control and monitor their sprinkler system from anywhere on Earth.

Rachio needed a way to power remote configuration across the platform, for both device control and device monitoring. The application needed to enable users to trigger irrigation action (like turn sprinklers on and off), and also stream realtime state of their system (see water levels, which sprinklers are on). To ensure reliable and secure remote configuration, Rachio needed a realtime data stream network to handle all signaling and messaging in the app.

Internet of Things Remote Configuration

At a large scale, remote configuration and monitoring can be a challenge. With any smart home solution, the platform needed high reliability and strong security, while ensuring the lowest, most realtime latency possible.

“A challenge we faced was how we would synchronize data across different clients. We needed a simple, scaled, low latency pub/sub architecture,” said Franz Garsombke, CTO of Rachio.

Rather than build a realtime messaging backend on their own, the Rachio development team implemented the PubNub Data Stream Network for all device signaling and platform monitoring. PubNub Pub/Sub Messaging powers all the synchronization of data between the multiple clients, delivering updated data in realtime to every connected device.

“We use PubNub to synchronize Iro watering events across multiple clients (iOS/Android/web app) and also being notified of device state changes. One benefit of this is it allows users logged into different client applications can see realtime watering events seamlessly occur.”

PubNub has provided Rachio a reliable and secure realtime backend infrastructure at the core of the platform’s architecture. Easy to implement and scalable, the Rachio platform can continue to grow without worrying about maintaining and orchestrating the realtime messaging powering their platform.

“It allows us to watch for watering or device state changes across different clients using just a few lines of code. We’ve never experienced a PubNub outage and it serves as a cornerstone of our architecture.”
