Yes, it can compatible with Echo devices. After an upgrade, Alexa now supports humidity. Why is the soil moisture and temperature sensor occasionally offline? If your soil sensor is located far from the hub, it may go offline. Consider adding some Zigbee repeater to enhance the Zigbee range, like Zigbee smart plugs, Zigbee smart bulbs, etc. Why is the soil moisture and temperature sensor occasionally offline?

Consider adding some Zigbee repeater to enhance the Zigbee range, like Zigbee smart plugs, Zigbee smart bulbs, etc. Why are the data from the Soil Temperature and Humidity Sensor different from regular temperature and humidity meter? This is because the measurement methods are different. The Soil Temperature and Humidity Sensor only detects soil surface temperatures for reference purposes only.

Review: These things rock! - I have used these for about a month now - they are quite reliable and provide good perspective on soil hydration. My temp sensor is pretty much right on with the other temp sensors in the reasonable range in our house. I keep the house around 70 and this thing seems to agree with the thermostat. If it were not accurate, it would be easy to fix - all thermos need calibrated from time to time and its fairly normal for one sensor to not match another. Pick the easiest to calibrate accurate - calibrate that one - then adjust the offset on everything else to match it. Quite easy to do this in Z2M - see the settings in photo attached. As far as the humidity in the soil - thats kind of a known problem as far as measurement goes. There isn't really a great way to test how much water is in soil... especially if you are attempting to do it with constant reporting over the course of a year with a AAA battery or two. The accuracy isn't the value here though. The value is in the trend reporting. I legit couldnt care less what the actual number is (or, more accurately, what its correlation to "true" is) - what I can do, however, is notice that after this sensor reports below 35 ( or whatever ) the leaves on my plant start drooping. That is the calibration - that is the accuracy. And this device is perfect in that scenario - I can see the trends and know what to do from there... No device at this price point or this level of energy efficiency will be able to do more than that - there are simply too many variables (everyone's rain and soil is different!). After observing trends for a while, you will realize the actual number doesn't matter. If it does matter, put it in the driest soil you can find and offset that to 0! As far as connectivity goes - I have had no issues. I have a robust zigbee network and it has a multitude of lightbulbs and other mains powered zigbee devices from which to join the mesh in its vicinity. A quick glance at my Z2M map shows it comically connected to one of the furthest possible bulbs at the moment and the connection quality is still fine. My only complaint on these (have a couple more on the way actually) is that shipping from desertcart is so slow but I am chalking that up to being a newer product. Review: Misleading advertising and poor Alexa integration. - I bought this specifically because it was advertised as a soil moisture sensor compatible with Alexa/Echo Zigbee hubs. After pairing it successfully, Alexa only shows the temperature reading. The moisture/humidity data that is heavily advertised is completely missing in the Alexa app. The product page makes it sound like you’ll be able to monitor soil moisture directly from Alexa, but that’s not true. Even the device screen in Alexa only displays temperature with humidity showing “–”. The sensor itself may technically support moisture readings through platforms like Home Assistant or SmartThings, but for Alexa users this is essentially just a temperature sensor. That should be clearly disclosed before purchase. Very disappointing and feels like false advertising for Echo/Alexa customers. ## Features - Zigbee Hub Required: Compatible with standard Zigbee 3.0, such as Echo (4th Gen), Echo Plus (1st Gen and 2nd Gen), Echo Studio, Eero 6, Eero Pro 6, Home Assistant (ZHA & Z2M), Hubitat and SmartThings Aeotec.

Very disappointing and feels like false advertising for Echo/Alexa customers. ### ⭐⭐⭐ Trying to HELP ThirdReality sell more *by N***A on March 14, 2025* I have other ThirdReality devices and other Zigbee devices to mesh around the house. These ground sensors easily connected to my newest SMARTTHINGS hub. One of these new sensors is 150 feet from the hub. I purchased a second pair after installing the first two when I found they quickly connected to my SMARTTHINGS hub. But, I yet do not know how to interpret the relative humidity readings (sensor shows 100% in cup of water and 0% on dry table). My problem was getting NO help from ThirdReality when I tried to use the moisture data to control my older WiFi-based sprinkler/soaker controllers. Alexa only sees the temperature readings. I spent several hours making the crossover and found the solution also helped with my other Zigbee devices. Condensed solution: I had to move my sprinkler controllers from SmartLife App to Gosung app. I used “outdoor” as a room for all Apps. Program WiFi sprinkler controllers as normal. Create a Gosung Tap-to-Run scene to activate “delay” function for 24 hours on EACH sprinkler controller. Go to SMARTTHINGS and create DEVICEs to delay each WiFi sprinkler controller scene using Partner Devices scrolling to Gosund. Gosund will link to SMARTTHINGS upon the initial creation. Add SMARTTHINGS scenes to activate each SMARTTHINGS device if moisture is above (say) 50%. Edit the SMARTTHING scene to run each morning (say 4am) prior to the program WiFi controller’s first open-time. This allows the WiFi timer-controllers to run normally if the THIRDREALITY MOISTURE is low. If THIRDREALITY moisture is high the WiFi controller will be delayed that day … repeats subsequent days is ground is still wet. Yes, backward logic … I hope THIRDREALITY understands my problem now … is there an easier way? I have duplicated the time-to-run routines (say 1am & 5am) to cover network-service gaps. ## Frequently Bought Together - THIRDREALITY Smart Soil Moisture Sensor,Zigbee hub Needed,Accurate Measure,Capacitive Probe,Moisture/Temperature Meter for Garden Planting,Compatible with Homey,Hubitat, SmartThings,Home Assistant - THIRDREALITY ZigBee Smart Plug 4 Pack with Real-time Energy Monitoring,15A Outlet, Zigbee Repeater,ETL Certified,ZigBee Hub Required,Work with Home Assistant,Compatible Echo Devices and SmartThings --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/659574488-thirdreality-smart-soil-moisture-sensor-3pack-zigbee-hub-needed-capacitive](https://www.desertcart.co.za/products/659574488-thirdreality-smart-soil-moisture-sensor-3pack-zigbee-hub-needed-capacitive) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-05*
