ECOWITT WS3900 Weather Station 7-in-1

This Ecowitt weather station combines outdoor robustness with a large indoor display to keep garden and home monitoring simple and visible. It pairs a 7-in-1 outdoor sensor array with a 7.5 inch colour LCD console, so you can check wind, rain, temperature and more at a glance. The system suits hobby meteorologists and homeowners who want continuous environmental feedback.

Quick overview

The WS69 outdoor array includes thermometer and hygrometer, rain gauge, wind speed and direction sensors, light and UV sensors, plus a solar panel. Short transmission intervals mean updates every 16 seconds, and the wireless range is up to 100 m, according to the manufacturer. The indoor WS3900_C console adds indoor temperature, humidity and barometric pressure reading on a clear colour display.

Strengths

The system offers hands‑free data sharing via Wi‑Fi, so measurements can be uploaded to Ecowitt Cloud and viewed on phone, tablet or browser. The console also acts as an IoT gateway to pair additional Ecowitt devices for broader monitoring and automation. Installation is straightforward, the outdoor mast mount suits poles of 1–2 inches in diameter, and the outdoor sensor can run on solar power or two AA batteries for backup.

Getting the most from it

Set up is done through the Ecowitt app or the local web interface, which guides Wi‑Fi configuration for 2.4 GHz networks. ECOWITT WS3900 works well when sensors are sited away from obstructions for accurate wind and rain readings. Ten en cuenta that some optional sensors mentioned are sold separately, and not all paired devices will display on the console even though their data can be uploaded to the cloud. 🌤️
