## Summary description

Sonoff THR316D is a DIN‑mount temperature and humidity controller with Wi‑Fi connectivity, 16A switching capacity and an integrated LCD for local readings. Designed for HVAC, greenhouse, aquarium or industrial automation, it monitors temperature and humidity and controls connected loads or relays via app, schedule and local display.

## Long description

The Sonoff Smart Wi‑Fi temperature and humidity controller THR316D converts a traditional thermostat into a smart controller in minutes. It provides continuous monitoring of temperature and humidity, supports multiple sensor types for different scenes, and offers dry contact output suitable for controlling boilers or other switch‑based systems. The unit features a flame‑retardant PC V0 casing, LAN fallback operation if Wi‑Fi is unavailable, and stores up to six months of hourly temperature and humidity history with export in .xlsx format.
Advantages
The device supports a variety of sensors (air temperature & humidity, waterproof water temperature, and soil moisture) via an upgraded RJ9 4P4C connector with hot‑plug capability for reliable connections. It includes surge protection with a varistor to absorb peak voltages, a 16 A max output for higher‑load devices such as electric floor heating, and a volt‑free (dry) contact output to control external systems without supplying power. THR316D keeps operating locally via LAN if Wi‑Fi is lost and sends push notifications when preset thresholds are reached. Data history can be reviewed by hour, day, or month and exported for record keeping.
Suitable for
 Home heating control (electric floor heating, boilers with dry contact)
 Greenhouse and indoor plant care (using soil moisture and temperature sensors)
 Aquarium water temperature monitoring (with waterproof temp sensor)
 Nursery rooms and baby care (environment temperature and humidity monitoring)
Key specifications
 Supply and relay output: 100–240 V AC, 50/60 Hz; max switching 16 A
 Dry contact (volt‑free) output rating: 5–30 V, 1 A max
 Casing material: flame‑retardant PC V0
 Wireless: IEEE 802.11 b/g/n, 2.4 GHz
 Mounting options: DIN rail and panel mount
 Measurements (approx.): 98 mm × 54 mm × (depth per manufacturer)
How to use
Install the THR316D on a DIN rail or panel and connect the mains and load according to the wiring guidelines for volt‑free output or relay output as required. Plug the chosen sensor into the RJ9 4P4C sensor port, power the unit, and configure the device through the eWeLink app or web control. Set target temperature and humidity thresholds, enable notifications, and create automation scenes or link the device to third‑party services as needed. If Wi‑Fi is unavailable, the controller will continue local operation via LAN.
Usage recommendations
Use sensors appropriate for each scene (waterproof sensor for aquariums, soil moisture sensor for plants) and ensure wiring and load do not exceed the 16 A rating. Keep the unit’s ventilation unobstructed and place sensors where they accurately reflect the monitored environment. Export history data periodically for records and configure push notifications to receive timely alerts.
