Dobry sensor bezprzewodowy
Sensor łączy się nie tylko z dedykowaną bramką WiFi. Połączył się z moją stacją sbs-ws-500 i dobrze pokazuje wilgotność gleby w ogrodzie. Wskazania mogę obserwować zarówno na stacji jak i w aplikacji Ecowitt. Polecam.

Removes the guesswork about when and how much to water.
This review evaluates the “WH51 Soil Moisture Sensor” made by ECOWITT. The product was shipped with no excessive or wasteful packaging. What’s in the box: one (1) WH51 soil moisture sensor, and an owner’s manual. I will preface this review by saying that I’m a Country Boy whose entire life has revolved around flower and food gardens. Any gardener will tell you that the quality of your soil is instrumental for crop growth. I recently purchased an Ecowitt WittBoy weather station that supports a multitude of add-on sensors, this soil moisture sensor being one of them. For years I have done away without using a moisture meter due to wildly inaccurate readings I would get; so I was eager to try this unit out. First impressions: The overall quality of the meter looks very good, with a durable hard plastic ABS casing. The end cap unscrews to house an “AA” battery (not included, lithium recommended). The weatherproof end cap is further protected by a slide-on rubber cap. It is imperative to note that this is not a standalone sensor; you need an Ecowitt monitoring hub. The set-up was easy: install a new battery, open the Ecowitt APP that you set up with your monitoring hub, and add the WH51 sensor. Within a minute the sensor calibrates and sends real-time data back to you via your monitoring hub/APP. I bought this sensor to specifically monitor my hanging potted plants. I tested unit one of my pots by placing it as instructed. After acclimating (about 10-20 minutes) the sensor reported that the soil moisture content was 33%. To check the accuracy of the sensor, I installed an old-school analog probe in the same pot. After acclimating (about 10-20 minutes) the analog probe reported that the soil moisture content was 35%. The sensor appears to be accurate within reason. The WH51 sensor removes the guesswork about when and how much to water. My only suggestion to the manufacturer is to include a lug to tie a tether with a tag so that you don’t lose/forget about the sensor when you dump the pot! Since this really doesn’t take away from the usability of the product, I will not deduct any stars for it. In order to determine long-term meter durability and accuracy, I intend to monitor this product over the next 4-6 months. Should anything change over this period, I will update this review accordingly. Cost-effectiveness and value: Overall I am very satisfied with the product; it is compact, portable, and easy to use. At a current price of $32.99 (plus a $3 off coupon), it is of great value. In summary: the “WH51 Soil Moisture Sensor” made by ECOWITT is well made, compact, accurate, and easy to use. It delivers all this at a reasonably low price. This product is a must-have for the avid gardener. I would recommend this product without reservation. Pros 👍: ✔ Well made from quality materials. ✔ Very easy to set up and use. ✔ Sensor reports back every 60 seconds (as configured by your monitoring hub). ✔ Uses one (1) AA battery. ✔ IP66 water resistant rated. ✔ Removes the guesswork out of when to water. ✔ Accurate. ✔ Great price point, good value. Cons👎: ✘ None! Manufacturer Suggestions 🖐: ✔ Provide a lug to tie a tether marker to avoid loss.

Molto utili per giardinieri smart!
Dopo aver acquistato due dispositivi per l'irrigazione automatica smart di altra marca, installati su un terrazzo, ho cercato a lungo dei sensori da mettere nei vasi per verificare che la quantità d'acqua erogata fosse sufficiente, ma non eccessiva, al fine di evitare cospique fuoriuscite di acqua dai vasi stessi (con inevitabile impatto sui precari equilibri condominiali...) Ne ho provati diversi ma ho scelto di acquistare 8 sensori ECOWITT perchè sono gli unici che presentano diverse utili caratteristiche: - Dati relativi all'umidità della terra (% e AD) facilmente consultabili da un'app dedicata - connessione a un piccolo hub in grado di rilevare temperatura, umidità e pressione ambientale, in aggiunta ai dati rilevati dai sensori connessi, dotato di ottima copertura radio e stabilmente collegato al servizio cloud via wi-fi - Integrazione disponibile per Home Assistant perfettamente funzionante - Possibilità di connettere i sensori alle stazioni meteo ECOWITT piu' complete - Lunga durata delle batterie Riguardo l'affidabilità posso dire che dopo due anni i sensori non mi hanno dato alcun problema e solo ora sto cambiando le pile inizialmente installate. Considerata l'esperienza positiva credo che sostituiro' presto gli altri dispositivi meteo installati (anemometro, pluviometro e diversi termometri interni ed esterni) con una stazione meteo integrata ECOWITT, dotata di display (in aggiunta all'app), che potrebbe sostituire il piccolo hub acquistato inizialmente per i soli sensori di umidità del suolo.

Excellent little devices for a very good price
I've had many manual probes for years that give very inconsistent readings, require me to actually think about checking the moisture levels in the first place, and cost more than these devices in the first place (assuming you already have the gateway). For the price I was expecting these to be a pain in the ass to pair, and struggle with range. My gateway lives in the middle of a double brick house tucked away in a comms cabinet with many other electrical devices. Yet out the box these pair automatically with the gateway, with excellent range (over 40m away through walls etc). Once setup, out the box the calibration was good, and they just work. Now I have graphs for the moisture levels, and email alerts if one of the probes drops below a given moisture level, simply amazing. Only think I would change, like others have mentioned, is add a light sensor. I don't consider it's a negative that it doesn't have one, it would just be a handy addition of which I would happily pay more.

Hands down the BEST soil moisture meters!
I have tried sooooo many different 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 which are very reliable and very accurate but you have to poke the soil in multiple places which damages roots, to expensive ones by Blumat that cost $90 per each 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. You can and should also buy their Wi-Fi Gateway that gives you access to the moisture meter data from anywhere in the world and it comes with graphs that show previous days, weeks, months 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 alert when soil goes below your indicated level which is very very useful. Now when it comes to raised beds and 20+ gallon containers I had 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 GW1100 Wi-Fi Gateway. The WH51L model had just came out 2 weeks ago and is only available on Ecowitt's site, but I was able to buy them 2 weeks prior to them being available for sale and it turns out both of these 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 gateway is located. I plugged in mine 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, however, they'll respond within 24 hours. 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 because you won't be disappointed. I was very surprised that they are very inexpensive in comparison to other meters who have half the functions or even quarter functions and work so great and the battery lasts way over a year. 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 🪴🪴 UPDATE: It's been 1.5 years since I got these sensors and the batteries gone from 1.6v power which is completely full batteries to now 1.5v and a couple of them at 1.4v which is almost full and still at 90% capacity. I haven't disconnected the batteries once and I use them continuously cycle after cycle and the only thing I do is I rinse them in between cycles and then insert them into the new container and change the name in the app and voila. Just amazing! 🤩
