Small sensor, compatible with Tuya and Home Assistant Damp bedrooms, a too-cold nursery, or mold behind a cabinet: you often notice it too late. The MOES ZSS-S01-TH is an ultracompact Zigbee 3.0 sensor that continuously measures temperature and relative humidity and wirelessly transmits that data to your smart home system. What sets this sensor apart is its exceptionally broad compatibility: tested and confirmed with multiple platforms. Key benefits 🌡️ Accurate measurement: temperature from -10°C to +60°C, humidity from 0% to 99% RH — practical deviations only ±0.5°C and ±2% RH 🔋 Energy-efficient Zigbee 3.0: operates on a single CR2032 coin cell battery; under stable conditions, only 1 update per hour 📡 Smart update frequency: every 10 seconds with large temperature fluctuations; once an hour under stable conditions, ideal for battery life 📐 Super compact: only 40 × 26 × 13 mm 🔔 Low-battery notification: available in Tuya Smart and Home Assistant 🧲 Flexible mounting: supplied 3M double-sided tape on the back cover, sensor remains easy to open for battery replacement 🔄 OTA updates: firmware can be updated wirelessly via Zigbee2MQTT, ZHA, and Tuya Compatibility — extensively tested Platform Works? Available data Note Tuya Smart (via Zigbee gateway) ✅ Full Temperature, humidity, battery, graphs Incl. notifications for low battery & high temp Google Home ✅ Full Temperature, humidity, battery Via Tuya Smart link; also on Google Nest display Apple HomeKit ✅ Partial Temperature, humidity Battery level not available via HomeKit Home Assistant – Tuya integration ✅ Full Temperature, humidity, battery Requires internet connection Sonoff iHost ✅ Full Temperature, humidity, battery, graphs Recognized as round model (cosmetic), works completely correctly Matter (via iHost as bridge) ✅ Partial Temperature, humidity Battery level not available via Matter ZHA (Zigbee Home Automation) ✅ Full Temperature, humidity, battery, firmware entity Works with any Zigbee Dongle Zigbee2MQTT ✅ Full Temperature, humidity, battery (%), voltage (mV) Version 2.1.1 tested; incl. calibration & OTA Amazon Alexa ✅ Supported Temperature, humidity Mentioned on packaging and in Tuya 💡 Tip for Home Assistant users: Zigbee2MQTT and ZHA provide the most complete local integration, without internet dependency. Via Zigbee2MQTT, calibration offsets for temperature and humidity can also be set. Technical specifications Property Value Model ZSS-S01-TH Protocol Zigbee 3.0 Temperature range -10°C ~ +60°C Humidity range 0% ~ 99% RH Operating temperature -10°C ~ +50°C Battery CR2032 (replaceable) Dimensions 40 × 26 × 13 mm Frequency band 2.405 ~ 2.480 GHz Max. transmit power < +10 dBm Update interval Variable (10 sec ~ 1 hour, based on change) Automation example Connect the ZSS-S01-TH to your bathroom fan via Zigbee2MQTT: as soon as the humidity rises above 70%, the fan automatically switches on. If the humidity drops below 60%, it switches off again. The sensor sends updates as soon as there is a significant change, allowing the automation to react quickly and energy-efficiently. FAQ Does the sensor have a display?No, the ZSS-S01-TH does not have a screen. Measured values can only be viewed via your smart home app, dashboard, or a voice assistant. Which hub do I need?You need a Zigbee 3.0 coordinator, such as a Sonoff Zigbee 3.0 USB Dongle, SmLight SLZB-06, HA Connect ZBT-2, or the MOES Zigbee gateway. Standalone use without a hub is not possible. How quickly is data updated?Depending on the degree of change: every 10 seconds with large fluctuations, once an hour under stable conditions. Deliberately designed for maximum battery life. Is the accuracy good?In practical tests, a maximum temperature deviation of 0.5°C and approximately 2% humidity deviation, which is normal for sensors in this class. Can the sensor receive firmware updates?Yes, OTA updates are supported via Zigbee2MQTT and ZHA. Does the sensor act as a Zigbee router?No, the ZSS-S01-TH is an end device and does not extend the Zigbee network. This is normal for battery-powered sensors. ✅ slimhuisje.nl – your technology partner for smart homes, we support you in every smart living adventure!
