Irrigation control unit PNI SWI170 Wi‑Fi, Tuya, flow 1700 l/h, fits 3/4" or 1/2"

The PNI SWI170 is a smart irrigation control unit with Wi‑Fi connectivity and compatibility with the Tuya platform. Designed for domestic and small commercial watering systems, it accepts 3/4" or 1/2" inlet/outlet fittings and supports a maximum flow rate of 1700 litres per hour. The unit enables remote scheduling and manual control via a mobile app, allowing automated watering of garden zones, lawns and container plants while monitoring basic flow capacity.

Advantages

The PNI SWI170 integrates Wi‑Fi control and Tuya ecosystem support to provide remote operation from smartphones and voice assistants connected to the same platform. Its dual fitting compatibility (3/4" and 1/2") simplifies installation on existing plumbing or irrigation lines. With a rated maximum flow of 1700 l/h the device is suitable for typical domestic irrigation demands and small green areas. The unit's app-based scheduling and manual override make it possible to tailor watering cycles to plant needs and local weather conditions.

Suitable for

• Domestic garden watering and lawn irrigation
• Balcony and patio container plant irrigation
• Small commercial or community plots with moderate flow requirements
• Zoned irrigation systems where a single smart valve controls one zone

When it may not be suitable

The SWI170 may not be suitable for large-scale irrigation systems or agricultural installations that require higher flow rates, multiple simultaneous zones, or industrial-grade valves. It is also not intended as a replacement for specialized pressure regulation or filtration equipment where those functions are required separately.

Key specifications

• Connectivity: Wi‑Fi (Tuya compatible)
• Maximum flow capacity: 1700 litres per hour
• Fitting compatibility: accepts 3/4" or 1/2" inlet/outlet connections

How to use

Install the unit inline with your irrigation pipework using the matching 3/4" or 1/2" fittings, ensuring a secure, leak-free connection. Connect the device to local Wi‑Fi and register it in the Tuya-compatible mobile app. Use the app to set watering schedules, define start times and durations, and perform manual on/off control as needed. Regularly check the connections and run brief manual cycles after installation to verify correct operation and flow.

What to consider before purchase

• Confirm your irrigation system’s pipe size and whether 3/4" or 1/2" fittings are required.
• Verify that a stable Wi‑Fi signal is available at the installation location for reliable remote control.
• Ensure the maximum flow of 1700 l/h meets the demands of your zone or fixtures.

Usage recommendations

For reliable performance, place the PNI SWI170 where it is protected from prolonged direct sunlight and freezing temperatures. Use the app schedules in conjunction with local weather patterns to avoid overwatering, and periodically inspect fittings for leaks or wear. If your system needs multiple zones, pair this unit with additional valves and a coordinated schedule rather than relying on a single device to serve a large area.
