What It Is

BlueSpray is a web- and Wi-Fi-based smart irrigation controller from Avidz LLC. Designed for both commercial and residential irrigation, it includes built-in Wi-Fi and Ethernet connectivity, allowing users to control it remotely via a mobile app or any HTML5 browser. Unlike many smart devices that rely on cloud services, BlueSpray emphasizes a “cloud-free” approach and can operate fully independently without monthly fees.

Core Dimensions

• Core Features: Offers unlimited programs and start times, with run times configurable down to minutes or seconds. It integrates NOAA weather forecasts to predict conditions 24 hours in advance and automatically delay watering. It supports rain, flow, and garage door sensors, and can even close a garage door automatically. Calendar views, system logs, and water-usage history reports are included, with support for expansion to up to 64 zones.
• Deployment and Data Security: Supports fully local deployment and continues running scheduled programs even when offline. Data transmission supports HTTPS/SSL encryption, with multi-layer security protections including WiFi security, login passwords, and a physical reset switch. It is also FCC/CE/UL/ETL certified.
• API and Developer Support: Provides a REST API based on HTTP POST. Its own UI is built on top of the API, meaning developers can achieve complete low-level control and easily integrate it into existing home automation systems.
• Team Collaboration and Permissions: Its unique “Discovery mode” allows landscaping technicians to access the device for maintenance via a local hotspot (192.168.123.1), without needing to enter the user’s home—balancing convenience with privacy.

Pricing

BlueSpray uses a one-time hardware purchase model with no cloud-service monthly fees. Specific hardware pricing is not disclosed in the source material.

Pros and Cons

• Pros: No cloud service or subscription fees required; usable offline; fully open API with excellent extensibility; supports HTTPS encryption for solid security; compatible with multiple sensors and offers a rich feature set.
• Cons: The device has no physical buttons and relies entirely on software control, which may be inconvenient during initial setup without internet access or when troubleshooting; custom UI images require externally hosted URLs, adding some complexity; it depends heavily on Google Map and NOAA, which limits usability in mainland China.

Who It’s For

Best suited for residential users with medium to large lawns, commercial landscaping managers, and advanced users who enjoy home automation systems such as Home Assistant.

Access from China

Partially restricted. Local network control is not affected, but the integrated Google Map and NOAA weather services are blocked in mainland China, so related advanced features may not work properly.
