Frequently Asked Questions (FAQ)
Q1: What is the difference between THS-317-ET and a standard ZigBee temperature sensor?
A: The THS-317-ET includes a 2.5-meter external probe that allows accurate temperature monitoring in remote or enclosed environments such as pipelines, freezers, or HVAC ducts — where built-in sensors cannot reach.
Q2: What is the measurement range and accuracy?
A: It measures from -40 °C to +200 °C, with a typical accuracy of ±0.5 °C in the main range (-10 °C ~ +55 °C).
Q3: Can it connect to my existing ZigBee gateway or BMS system?
A: Yes. It is fully compatible with ZigBee 3.0 networks and works with gateways such as Home Assistant (ZHA/Zigbee2MQTT), Jeedom, and Amazon Echo Plus.
(Note: Not compatible with Tuya ZigBee gateways.)
Q4: How is the device powered and how long does the battery last?
A: Powered by 2 × AAA batteries, the sensor features ultra-low power design, typically lasting up to 2 years depending on reporting frequency.
Q5: Is OEM or customization available?
A: Yes. OWON provides OEM/ODM customization, including firmware adjustment, logo printing, and housing design for system integrators and distributors.
