The WH40 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 low maintenance.
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.
If you opt for the GW1200 gateway as part of the package, as well as the features above, it also has the ability to control Ecowitt IoT devices such as smart plugs and water timers.
The GW2000 gateway again has the above features, but also adds the ability to control the Ecowitt Internet of Things devices such as power sockets and water valves.
Finally the GW3000 gateway has all of the above features, but also adds a microSD card slot for local data recording and an external antenna for improved communications.
