Ecowitt GW1100 Wi-Fi Weather Station Sensor Gateway with Temperature, Humidity and Atmospheric Pressure 3-in-1 Probe Sensor(1X GW1100 WiFi Gateway)

I have tried sooooo many moisture meters from really cheap crap with double metal rods that show light intensity, moisture, and soil pH which is always inaccurate, single metal rod by XLUX company and those are reliable and very accurate but you have to poke the soil in multiple places which damages roots, also used the Blumat $90 meter which is way overpriced and it only shows the moisture without any graph 📈 or remote Bluetooth or Wi-Fi capabilities, and bunch of other ones that were always showing wrong readings until someone told me to try these Ecowitt WH51 and WH51L sensors. The WH51 model is great and shows moisture levels from the top 7 inches of soil which is great for all types of pots up to 7 to 10 gallons. The beauty about this Wi-Fi Gateway is that you have access to the data from anywhere in the world and it comes with graphs that show previous readings that you can compare and dial in your watering habits for better performance. You can add up to 8 devices per each GW1100 Wi-Fi Gateway and it comes with an app as well as their website and you can set up alerts to come in through the app as well as get an email when soil goes below your indicated level which is very very useful. Now when it comes to raised beds and 20 gallon containers I have to purchase the WH51L model which comes with a probe attached to 1 meter long cable which allows you to use them in deep pots/beds/containers and they can also be connected to the same Wi-Fi Gateway. Both models are very accurate. The Wi-Fi gateway also has a temperature and humidity and pressure sensor which gives you readings of the room where the sensor is located. I plugged mine in inside my grow room next to my grow tents to monitor the temperature and humidity inside that room to make sure my grow tents are in an optimal environment. I can't say enough good things about Ecowitt. Customer service is very helpful and very responsive. The only thing I did not like is that they are based in China and you can't really call them and the only method of communication is via email but like I said they are very helpful and responsive. If you haven't tried this company yet then don't waste your money on anything else and do yourself a favor get this Wi-Fi gateway along with the moisture meters and anything else you might need because you won't be disappointed. I will surprised that they are so inexpensive and work so great. I mean when comparing to the Blumat meter that cost $90 it's like comparing apples to oranges because for $90 it should be able to do more, at least have remote capability but it doesn't even have that option. In my opinion it's extremely overpriced and these Ecowitt devices without a doubt are blowing away Blumat meters. I hope this helps.

I bought this because it seems to be one of the only devices that can be accessed from a computer rather than only a phone app, and even if internet service is interrupted. This tiny device (about 1x2 inches) connects via wifi and serves up a web page on my LAN with the entire interface for setup and viewing. I can view it on my phone, too, of course. I have my own custom-built monitoring software (yes I'm a nerd) and I can still access data simply, through the web page interface, and record data even during network outages or even power outages, since my system is on a UPS. The GW1100 has a built in thermometer, but I also bought the WH31 915MHz wireless thermometer module. Setting up the GW1100 and the WH31 was easy. I do have quite a bit of experience, but the setup process was clear and understandable and worked first try. I registered with ECOWITT during setup but I think that wasn't really necessary. The $20 price tag is VERY reasonable. The WH31 was only $16. I've been trying to get similar $35 Ambient add on thermometers to work with my Ambient weather stations' ObserverIP network interface, but even though the ObserverIP serves up a similar LAN accessible web page it refuses to show additional devices on it's web page and requires going through Ambient or Weather Underground servers. Interestingly, the GW1100 also found my Ambient weather station, and will display all of its data. I hesitated to try this product, as it looked too good to be true. But it was true. It does happen once in a while! It's a pleasure to write a positive review about an excellent product.

I couldn’t be happier with the Ecowitt GW1100. What really stands out is how simple it is to set up and use. Within minutes of unboxing, I had it connected to my Wi-Fi and syncing perfectly with my sensors. The intuitive interface makes it easy to monitor all the data without any steep learning curve. Unlike other weather gateways that can feel clunky or overcomplicated, the GW1100 is refreshingly straightforward — just plug it in, follow a few basic steps, and you’re ready to go. If you’re looking for a reliable, no-fuss gateway that just works, the Ecowitt GW1100 is an excellent choice.

This is better that the original unit. Though I never had an issue with the original. Distances to sensors and my base wifi hub works well 150 feet to the sensors and 40 feet from unit to wifi hub.

Great product, quick updates, works well with Home assistant.

I am super happy with all the Ecowitt products I have purchased. They are remarkably inexpensive and yet they work perfectly for me. I started with a pool temp sensor and then added the gateway, and then bought four more temp/humidity sensors. They are super easy to set up. The phone app is clear and has the functionality that I need. These things could be priced more expensively and still be good value. This is a no brainer purchase and you'll be happy with them.

I needed to find a USB-A power supply for this device. It has been working flawlessly for over a week now.

Ecowitt weather station kit = highly recommended for home use. Wide variety of sensors available, all connect on (AU) 433MHz wireless to base stations / display base stations. Easy to set up, able to be tweaked to a decent degree for home use, including calibration / offsets. Bang for buck is very high.
