Common questions about manuals, registration, and support for this brand.
Shenzhen Fine Offset Electronics is the manufacturer behind the Ecowitt brand. They also manufacture weather instruments for various other private labels worldwide.
Most Fine Offset and Ecowitt sensors can be connected to a Wi-Fi Gateway (such as the GW1000 or GW1100) to stream live data to the Ecowitt Weather Server (ecowitt.net) or the WS View mobile app.
Check the batteries and ensure they are inserted correctly. For outdoor sensors, try a reset by covering the solar panel, removing batteries, waiting 60 seconds, and re-inserting them. Ensure the gateway is within wireless range.
Manuals are often updated on the Ecowitt website support section. Firmware updates for Wi-Fi gateways are typically managed directly through the WS View app.
