## Description

Thermometer and Hygrometer eTHS, WiFi Smart Temperature and Humidity Monitor Sensor, APP Phone Alert, TH2MQTT Home Assistant, Works with Alexa Google Home, No Hub Required

## Features

- 【Accurate and Fast Reading】Powered by the world top sensor Sensirion from Switzerland, eTHS provides temperature accuracy up to ±0.54°F/±0.3°C and humidity accuracy up to ±2%RH. Data is refreshed every 2 seconds ensures instant updates and automations.
- 【TH2MQTT Home Assistant】TH2MQTT is a bridge that connects a temperature and humidity sensor (TH) to Home Assistant using the MQTT protocol. This allows Home Assistant to monitor and react to changes in temperature and humidity. For example, it can trigger actions like turning on a air conditoner when the temperature is too high, or activating a humidifier when the humidity drops below a certain level. Essentially, it enables you to automate your home environment based on real-time temperature and humidity data.
- 【WiFi Connection Without Hub】Why paying more to buy another hub and add troubles? Unlike other Bluetooth sensors, eTHS is always connected to Internet with WiFi (2.4G) directly. 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.
