Ecowitt Wireless Soil Moisture Sensor WH51 - Plant Water Monitor, Soil Hygrometer Tester with Email Alert, Just Accessory Sensor for Ecowitt Ecosystem…

I've been using these soil moisture sensors with my weather station setup, and they've become one of the most useful tools I have at my allotment. The sensors were easy to pair with my Ecowitt system and started reporting data almost immediately. Once installed, they provide continuous soil moisture readings without needing to dig around in the soil or rely on guesswork. I use them to monitor several growing areas, and they've helped me make much better decisions about when to water. It's surprising how often the soil moisture level is different from what you'd expect by simply looking at the surface. The sensors are compact, unobtrusive, and seem to cope well with outdoor conditions. Battery life has also been excellent, meaning they can be left in place for long periods without needing attention. One of the biggest benefits is being able to view the data remotely through my weather station system. Whether I'm at home or visiting the allotment, I can quickly check moisture levels and see which areas need attention. Since installing them, I've wasted less water and have been able to keep conditions more consistent for my plants, especially during warm and dry periods. Overall, these are excellent sensors for anyone using an Ecowitt weather station. They provide reliable data, are easy to install, and take much of the guesswork out of watering. Highly recommended for gardeners, greenhouse growers, and allotment holders alike. Oh and pairing is a breeze, simply install the battery and they autopair with my existing ecowitt setup!!

I bought this so I can monitor my seedum roof on my office/shed. This lets me know when it needs to be watered. And so far its been a great help. The reason for going this route was because I thought I nearly killed it. But with this as an aid, the roof has quickly bounced back to life. It was easy to setup and get up and running. The app is a bit basic but does what you would expect and keeps all the readings on one place. I was a bit dubious of the build quality. But it seems up to the job. But time will tell on that. Fortunately its cheap enough to replace. As long as I get a minimum of a rear from it. You will of course need to buy the unit which talks to this and gives you access via wifi. But the good news is once you have purchased it. You then have the hub and ready to expand. I will be expanding this to the full weather station shortly. One thing I would really like to see is smart home integration. For exsample, once the soil on the room gets below a certain threashold, and the weather is not expecting rain for the next 24 hours. Then this would automaticly tell my automated sprinklyer system to turn on and water the roof and plants. Long term this would save money and not waste water. Of course this is great for when you are away as well.

Great sensors. But be aware of distance from hub and walls between the sensors and hub. Integrated into home assistant really well.

I already have their HP2551 weather station which is compatible with this sensor. I just put in a battery and the weather station found this sensor straight away, no set up needed. the Ecowitt app also displays its reading. Did as suggested to check it and it reads 0 in the open air and 100% in a glass of water so it seems to be functioning correctly. Included is a plastic cap to cover over the battery compartment so it seems earlier criticism of water ingress has been addressed. It's been very very wet since I bought it so the sensor (which I leave permanently in my garden) is giving me a reading between 78% and 84%, yes I live in a swamp at the moment!!

Three years in and sadly one of our sensors has failed. Can not really argue with that. It worked well and was in a moisture sensitive plant so helped with keep up with watering.

Works great !! But the only problem is, the blade that you put into the soil to measure its moisture content is so wide, it cuts the roots on your plant. I don't really have a way to test how accurate it is, but I can tell you it reads 0% moisture in dry air and 100% moisture when dipped in water, so it's at least got the two boundaries right.

For those using Ecowitt products, no comment is necessary. The only thing I would say is to be careful when placing the sensor in the ground. The 'spike' is relatively fragile and you should bury it rather than try to push it into the ground. Also, place it somewhere where it won't inadvertently get stepped on, again, they are easily broken. Finally, raised flower beds are tempting but bear in mind that they are typically better drained than level ground and the sensor reading will reflect that. Also, I have seen comments about moisture getting in the electronics. The sensor I just received was supplied with rubber caps to prevent this.

Very handy work as they should

Works well with my ecowitt weather station and reads the soil moisture. I'm new to this and not sure how to validate if the measurements are accurate, but after watering the lawn it gets to around 90/95% and drops gradually until the next watering session.

ho usato tanti sensori per controllare l'umiditá del suolo, ma questo é il primo affidabile, in abbinamento alla sua centralina é anche facilmente integrabile in Home Assistant, anche il raggio del segnale é perfetto, 30m senza problemi con due mura in mezzo.

Einwandfrei arbeitender Bodenfeuchtesensor mit hoher Genauigkeit. Hab das Teil gekauft, um die Feuche bei meinem Bambus im Garten messen zu können und bei Bedarf wässern zu können. Das hab ich nämlich gerne mal im Winter vergessen. Der Sensor benötigt ein Gateway für knapp 30€ und koppelt sich quasi wie von selbst damit. Die App an sich ist okay, mehr nicht. Ziemlich hässlich, aber zeigt alle Werte sofort graphisch an. Durch die einfache Einbindung schonmal ein Pluspunkt. Der Sensor gibt die Feuchte in % an - in Wasser getaucht ergeben sich 99%. Ab welchem Wert man dann die Pflanze wässern muss, ist vermutlich Erfahrungssache. Allerdings nutze ich die App nicht, sondern HomeAssistant. Die Einbindung hier funktioniert extrem einfach, die Integration gibt lediglich eine Adresse an, die man innerhalb der App eintragen muss und schon stehen alle Entitäten zur Verfügung (Achtung: Der Bodensensor stellt nur die Bodenfeuchte und Batteriespannung zur Verfügung, sonst nix. Das Gateway allerdings hat auch noch Temperatur, Luftfeuchtigkeit und Taupunkt integriert - man hat also für den Preis des Gateways auch noch einen gut in HomeAssistant integrierten Temperatursensor). In HomeAssistent stehen dann natürlich alle Möglichkeiten zur Benachrichtgung und Automatisierung zur Verfügung. Ja, der Sensor ist etwas teurer als Bastellösungen von AliExpress oder so - aber er funktioniert innerhalb von nicht mal zwei Minuten am Gateway und in HA. Auch ohne HA ist die App sicherlich nutzbar, aber eben hässlich wie die Nacht. Bei Regen bemerkt man die Änderungen der Bodenfeuchte mit entsprechender Verzögerung, da der Sensor mehrere cm tief im Boden steckt. Aber in den letzten Tagen war jeder Regenschauer mit für mich plausiblen Erhöhungen der Bodenfeuchte verbunden. Wenn man das Gateway einmal beschafft hat, bietet EcoWitt noch jede Menge andere Wettersensoren an. Alle Sensoren erscheinen (laut Beschreibung) auch ebenso problemlos in HA. Hier bietet sich vermutlich noch ein Regensensor an, interessant fand ich auch eine Pooltherometer. Mittels HA kann man sich hier viele tolle Automatisierungen vorstellen. Fazit: Ja, das Ding eignet sich super für die Bodenfeuchte. Aber die Möglichkeiten mit HA sind quasi jeden Cent wert.

Il a juste suffit de mettre les piles dans le dégtecteur d'humidité et 30 sec apres il apparaissait sur le tableau de bord de ma station méteo. Utilisé sous Home Assistant pour réguler un arrosage automatique.

Perfekt!
