## Summary description

Sonoff THR316 is a DIN‑mount smart temperature and humidity controller with Wi‑Fi connectivity and a 16A switching capacity. It monitors ambient temperature and humidity, triggers outputs or automations based on set thresholds, and integrates with smart home systems for remote control and scheduling. Suitable for HVAC, server cabinets, greenhouses and home climate control, it provides automated environment regulation and remote monitoring.

## Long description

Sonoff THR316 is a DIN-mount temperature and humidity controller with Wi‑Fi connectivity and a 16A switching capacity. It monitors ambient temperature and humidity, records historical data up to six months, and enables automated control or notifications when preset thresholds are reached. The device supports multiple sensor types via an RJ9 4P4C connector and can operate locally when LAN control is available, making it suitable for HVAC, cabinets, greenhouses and other environmental monitoring applications.
Advantages
The controller uses a V0 flame-retardant PC casing and a varistor to absorb peak voltages for improved safety. It supports hot-pluggable RJ9 sensor connections for stable sensing and can directly switch loads up to 16A, enabling control of equipment such as electric floor heating. The device stores up to six months of temperature and humidity history with hourly accuracy and allows export in .xlsx format. LAN control ensures continued operation if Wi‑Fi is disconnected, and the unit integrates with eWeLink, Home Assistant, IFTTT and voice assistants for broader automation.
Suitable for
HVAC systems and room climate control
Server or electrical cabinets requiring environmental monitoring
Greenhouses and plant growth control with soil moisture sensing
Aquariums and pond setups using waterproof temperature sensors
Irrigation systems and automated watering control

How to use
Mount the Sonoff THR316 on a DIN rail or panel and connect mains power (100–240 V AC). Plug the appropriate sensor into the RJ9 4P4C socket (temperature & humidity sensor, waterproof temperature sensor, or soil moisture sensor) depending on the application. Configure thresholds, schedules and automation rules via the eWeLink app or web control; the device will operate locally via LAN when Wi‑Fi is unavailable. For integrations, add the device to Home Assistant using the eWeLink add-on or link it with IFTTT and supported voice assistants for remote control and scene automation.
Usage recommendations
Install the controller in a dry, ventilated location away from direct heat sources. Use appropriate sensors for each application (waterproof sensor for aquariums, soil moisture sensor for plants), ensure wiring conforms to local electrical codes, and avoid exceeding the 16A load rating. Regularly export or back up historical data if long-term records are required.
