The WH40H rain gauge and a choice of Ecowitt WiFi gateway allows you to record rainfall readings and upload to the Ecowitt network and other online services. Exceptional accuracy at 0.1mm / 0.01inch resolution and the rain gauge is self emptying for minimum maintenance with anti bird spikes and rain debris filter also included.

The GW1100 model includes builtin temperature, humidity and barometric pressure sensors for indoor readings. The gateway has these sensors on a wired probe so that they can be kept away from sources of heat which would skew readings. As well as these features it also has the ability to control Ecowitt IoT devices such as smart plugs and water timers.

Finally the GW3000 gateway includes the above features, but also adds a wired LAN port, microSD card slot for local data recording and an external antenna for improved communications.
