Would like to add the anemometer to connect to it as well.** A: No, Ecowitt is designed to be web-based. Actually web offers more flexibility since data is accessible from anywhere, and alerts for high winds can be easily set. I'd always wanted an display too, but in retrospect the Ecowitt modular system for web data is far more useful. **Q: Can this track daily rainfall for the month or does it just do like others, 1 day, 7 days, month?** A: Hi, you can track daily rainfall records and graph at least one year on our ecowitt weather server: ecowitt.net after uploading the data to it(you'll need to buy a GW1000 wifi gateway to support that). Any other question, please contact us at support@ecowitt.com. **Q: Does my phone need to be on the same wifi network as the gateway in order to view the rainfall data, or can i be in another town and access the data?** A: Hello, to view the live data on your phone it requires your phone and the gateway to be at the same network. You can upload the data to our free weather server and then you can view the data remotely by visiting the website. Any other question, please contact us at support@ecowitt.com. **Q: Can the device be set up to automatically upload the data to your server?** A: Absolutely. The GW1000 Gateway transfers the data securely to the Ecowitt server in a format you can choose to download or share to established PWS hosts like WeatherUnderground – you can also configure uploads to your own server easily. ## Frequently Bought Together - ECOWITT WH40 Wireless Self-Emptying Rain Gauge Sensor, Rainfall Collector - Accessory Only, Can Not Be Used Alone - ECOWITT Wi-Fi Gateway Weather Station, with Built-in Temperature, Humidity, and Barometric Sensors, IOT Ready, Supports Ecowitt Sensors Developed, USB Power, 915 MHz - ECOWITT Wittboy Pro Weather Station HP2564, with 7 Inch HP2560 TFT Display Console and WS90 Outdoor Weather Sensor, Supports WU/WeatherCloud/Wow/Ecowitt Servers,915 MHz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/272768445-wh40-wireless-self-emptying-rain-collector-rainfall-sensor-accessory-only](https://www.desertcart.co.uk/products/272768445-wh40-wireless-self-emptying-rain-collector-rainfall-sensor-accessory-only) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-17*
