TH Elite is a Wi-Fi smart relay with a built-in screen that switches heaters, fans and pumps automatically based on temperature and humidity.
Connect a compatible sensor and it'll switch whatever's plugged into it when conditions change: run a dehumidifier when things get damp, a heater when the greenhouse gets chilly, or an irrigation pump when the soil dries out. It connects straight to your 2.4GHz Wi-Fi, so there's no hub needed, and you can control it from anywhere with the eWeLink app.
The LCD screen shows the current temperature and humidity, updating every five seconds, so you can check on things without reaching for your phone. It switches loads up to 16A, and there's also a dry contact output, so you can use it in place of a thermostat to control boilers and HVAC systems.
This device connects to mains wiring, so you'll need to be confident installing it safely - if in doubt, ask a qualified electrician. Sensors are sold separately.
What's New? ✨
Compared with the TH Origin, the TH Elite adds a built-in LCD screen, a dry contact output and exportable history data.
Get Smart, Automate!
This is a smart switch, so the fun really begins when you connect it to your home automation system.
Turn on auto mode and the relay switches on or off whenever readings cross the thresholds you set, or create up to eight automation programmes based on temperature, humidity and time. You can also look back through up to six months of temperature and humidity history in the app, and export it as a spreadsheet.
It works with the eWeLink app straight out of the box, as well as Amazon Alexa and Google Assistant.

Notes
- You'll need a sensor to use auto mode. The THS01 temperature and humidity sensor and WTS01 waterproof temperature sensor plug straight in, and the MS01 soil moisture sensor comes with an adapter.
- It only connects to 2.4GHz Wi-Fi networks.
