Review: Simple setup, great functionality - Bought this after having purchased an Ecowitt WH40 rain gauge, decided that it would be nice to be able to view the output on my mobile as well as the display panel in the kitchen. Download the app and register with Ecowitt for a free account. Can then see a global map with Ecowitt users' data from their weather stations. Fascinating! This gateway receives the data frame transmitted from the rain gauge every minute to the display panel. Then sends the data to the Ecowitt server which in turn pushes it back to your mobile, tablet or computer. There's also the option to make the data publicly available. Tiny little box with a USB-socket on the back. Just power it from an old mobile charger - cable supplied for that. There's a remote sensor on a wire fixed to the gateway for internal temperature and humidity plus an internal barometric pressure sensor. Setup involves connecting to your mobile via a temporary wifi hotspot in the sensor to configure it to connect to your normal wifi. Plus a few other settings which are self explanatory. On the front are LED indicators for Wifi and RF (from your sensors) to confirm all is working OK. Once complete my local rainfall and barometric pressure was publicly visible. My phone & tablet Ecowitt apps show the same plus internal temperature and humidity. So simple and so neat. Finally purchased a WN32 outside temperature and humidity sensor. Put the battery in and 1 minute later this data was available too - no further configuration needed. Can't recommend this and the other Ecowitt pieces highly enough.
Review: Good Weather Station - with one caveat - I purchased this GW2000 with the WS90 7in1 sensor array (piezo rain guage) and a separate tradional WS40 rain sensor - I wanted to compare the two methods for accuracy. I've had a Youshiko weatherstation for years and prodiuce offline analytic on excel so I consider myself a demanding weather buff. Pros: Plenty of sensor choice. Good display & analytics. I post my data to Wunderground, Weathercloud and Met Office WoW sites..this works perfectly though working out how to connect to the Metoffice site is challenging..you make up your own station key - it doesn't come from them i.e. it's really a password. The Wunderground site graphing is best to show if you have intermittent connectivity as they show the gaps in data (see cons below) Really good battery level reporting showing voltage of sensor battery and the solar (capacitor) voltage..this is great as it means you don't have to get a ladder out if you suspect the batteries need changing. Use Lithium batteries for best results. Do not use NiCd as these have a lower voltage (1.2V~ compared to 1.5V). Ecowitt App is very good I use it on an Android Samsung tablet instead of buying the bespoke display which is expensive. Cons This applies to the GW2000 (sw 3.0.6) only not the sensors. I initially connected to my wifi router..only 2.4GHz band supported (10 feet away). I kept seeing varying signal strength 5 bars to none regularly dropping out..the Ecowitt live data view is written to make you suspect the sensor to GW2000 connectivity is the issue..It isn't, their 'signal strength' icon actually refers to the wifi strength. I swapped to RJ45 wired connectivuity turned off the wifi on the GW2000 and it has been rock solid ever since. So far I really recommend Ecowitt..longevity of sensors I can't comment on yet.

### ⭐⭐⭐⭐⭐ Tested. It works.
*by J***M on 13 May 2025*

I must say, I’m surprised at just how well this lightning sensor works. I was lucky enough to have a major thunderstorm forecast in my area within 24 hours of setting it up, so I was able to see it working! See the photos of the display console and the graph from the app. I installed the lightning sensor with Energiser lithium batteries and the switches in default setting. Installation was easy. I already had an Ecowitt HP2564 weather station and display console (which discovered the new sensor immediately), so I attached the lightning sensor to the plastic mounting pole (see attached photo). During a thunderstorm the following day, I saw a lightning flash, followed some seconds later by thunder. About a minute later, the weather station recorded the strike at about 5 miles distant, which seemed right by my calculations. The most distant strike recorded was at 27 miles. I am very pleased with my purchase. It performs as well as I had hoped.
