Watch data from anywhere at any time and avoid any potential failure due to signal conversion. - 【App Real-Time Status and Alert】View current status and 24-hour data curve even you are not at home. Set higher and lower limit to get immediate alerts for abnomities, helping you respond faster to sudden changes in environments such as greenhouses and basement storage. - 【FREE Data Storage and Export】eTHS offers world's longest FREE data storage for up to 3 years. You can view detailed data history after years and export full data to Excel file at any time for records tracking. - 【Works with Alexa/Google】eTHS works with Alexa and Google Home for voice interaction. No need to find and check sensor details in App but just ask Alexa or Google Assistant the temperature or humidity data in specific room. Use Routines in Alexa App as an event to interact with products from other brands. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | LinknLink Pty Ltd | | Part number | eTHS | | Item Weight | 50 g | | Package Dimensions | 7.5 x 4.7 x 3.9 cm; 50 g | | Item model number | eTHS | | Colour | White | | Style | Contemporary | | Power source type | Corded Electric | | Item Package Quantity | 1 | | Measurement Accuracy | +/-0.9℉ | | Display style | Lcd | | Special Features | App Companion, High Accuracy | | Included components | Product, sensor cable, user guide | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** LinknLink - **Special feature:** App Companion, High Accuracy - **Colour:** White - **Age range (description):** Adult - **Included components:** Product, sensor cable, user guide - **Outer material:** Plastic - **Display type:** Lcd - **Connectivity technology:** Wi Fi - **Product care instructions:** Wipe Clean - **Unit count:** 1.0 count ## Images ![eTHS - Image 1](https://m.media-amazon.com/images/I/519beMxxiHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Wifi temperature and humidity sensor that works well with Home Assistant *by S***R on 22 June 2025* I had a number of Zigbee temperature and humidity sensors around the house to monitor how well the central heating works in each room but needed to add a wifi temperature sensor in the garage as the Zigbee signal doesn't reach that far. I saw this reviewed on YouTube and am glad I bought it as it seems to be accurate and the USB power, rather than batteries, suits me well as I don't have to run around changing batteries all the time. Has never lost connection in the six months I've owned it and works well in Home Assistant. Will probably buy some more for monitoring the temperature in the garden and greenhouses. ### ⭐⭐⭐⭐ Software update *by D***S on 31 January 2025* Used to have missing chunks of data and couldnt connect. since firmware update has been excellent with no issues. ### ⭐⭐⭐⭐⭐ Really great sensor *by M***E on 8 November 2023* I can't believe I'm the first to review this unit. I'll start by saying it doesn't take batteries, so you'll need a usb plug or port nearby. The setup of this unit was super easy and you'll have it working in about 5 mins. Currently there is a few ways to get it to trigger a routine and work with Alaxa and there is quite a lot of scope that's not immediately obvious. I can't say enough about the fantastic tech support for this product. I would thoroughly recommend this product especially at the insanely low price. It's a really good sensor with a great app. ## Frequently Bought Together - LinknLink Thermometer and Hygrometer eTHS, WiFi Smart Temperature and Humidity Monitor Sensor, APP Phone Alert, TH2MQTT Home Assistant, Compatible with Alexa Google Home, No Hub Required - 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 - Zooz 800 Series Z-Wave Long Range S2 USB Stick ZST39 LR, Great for DIY Smart Home (Use with Home Assistant or HomeSeer Software) --- ## 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.kr/products/574208305-eths](https://www.desertcart.kr/products/574208305-eths) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-23*
