A Weather Station of My Own

Living on the ocean in New England has taught me one thing: weather forecasts rarely agree. Ask Alexa, Siri, and the local news, and you’ll get three different answers.

For years I thought about getting my own weather station, but other projects always seemed to come first. When Sainlogic offered to send me their SA9, I jumped at the chance to test it out.

The timing couldn’t be better. Hurricane season is here, and according to the National Weather Service’s 2025 hurricane predictions, forecasters expect an above-average season for storms. With climate change fueling hotter summers, and more frequent and severe weather, having reliable data in my own backyard feels more important than ever.

The SA9 promises real-time accuracy, app connectivity, and features once reserved for professional stations. In this Sainlogic SA9 review, I’ll walk through the unboxing, setup, and how well it actually works.

System Overview

The SA9 combines three core elements—an outdoor sensor array, an indoor display console, and the Weatherseed app-working together over Wi-Fi to give you a complete picture of your local weather.

• Outdoor sensor array (7-in-1): Mounts on a mast, pole, or eave. Tracks wind speed, wind direction, rainfall, temperature, humidity, UV, and sunlight. Powered by solar with battery backup for continuous operation.
• Indoor display console: Plugs into AC, connects to 2.4 GHz Wi-Fi, and presents a bright 8.15-inch color display of your current readings. It also pushes data to the Weatherseed app.
• Weatherseed app & cloud: Adds AI-powered 24-hour and 7-day forecasts, instant app/email alerts, and exportable historical data. You can also publish your station to Weather Underground for easy sharing.

Installation & Setup

For this Sainlogic SA9 review, I found the installation process straightforward once I understood the mounting choices. The outdoor sensor can be secured in four different ways:

• Mount on top – attach to a flat surface, such as the top of a post or deck rail.
• Mount on pole (top) – secure to the top of a vertical pole, which can also be set in the ground for a freestanding installation.
• Mount on side – fasten directly to the side of a wall or post.
• Mount on pole (side) – clamp to the side of a vertical pole.

The sensor is powered by its solar panel with AAA battery backup, so once it’s in place it requires very little attention.
