The Ecowitt WH57 Lightning sensor with a WiFi gateway is an ideal starter set for those with an interest in lightning detection and weather.

Start with this sensor and add additional sensors as your interest grows building a modular weather station with full internet access.

The GW1200 WiFi gateway 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 model again has all of the above features, but also adds a wired LAN port, microSD card slot for local data recording and an external antenna for improved sensor reception.

Pair with one of these, the WH57 lighting detection sensor collects data from up to 25 miles from the sensor and is housed in a protective shelter.  Lightning data is uploaded to the Ecowitt weather network which displays strike count, distance and the time recorded. Using the Ecowitt network you can also receive emailed lightning alerts.

Unlike some other brands, the Ecowitt WH57 and gateway can be expanded with a variety of additional sensors, click here to view the latest Ecowitt sensor matrix.

All of these are available to view in the App, or online via Ecowitt.net and in the 3rd party services that support the sensor type.

You can view data from our own WH57 lightning sensor which is connected to a WittBoy Pro here.
