For the terrarium: the Sonoff TH Elite 20A thermostat with its temperature and humidity probe switches the heat lamp on at the temperature you choose, while the Sonoff S60TPF plug runs the UVB lamp at fixed times. All over Wi-Fi, no hub, with history and notifications from the eWeLink app.
What it does
- The Sonoff THS01 probe measures temperature and humidity in the terrarium and sends them to the TH Elite.
- The TH Elite switches the heat lamp on when the temperature falls below the set value and off when it reaches it, even without internet.
- The TH Elite display shows temperature and humidity at a glance.
- The S60TPF plug switches the UVB lamp on and off at fixed times, for a steady photoperiod.
- The eWeLink app sends a notification if temperature or humidity leaves the range you set.

Before you order
Do you need a hub?
No: the TH Elite and the S60TPF plug connect straight to the home Wi-Fi and are managed from the eWeLink app. All you need is good 2.4 GHz Wi-Fi coverage in the room with the terrarium.
Does it work with Alexa and Google Home?
Yes: Sonoff Wi-Fi devices are added to the eWeLink app and from there connect to Alexa and Google Home through the eWeLink skills. You can ask by voice to switch things on and off and to read out the temperature. Automations are still best set up in eWeLink, where you choose thresholds and times.
Do you need an electrician?
Yes for the TH Elite, which is wired at 230V between the supply and the heat lamp. The 230V connections must be made by qualified personnel with the system isolated. The S60TPF plug for the UVB lamp, on the other hand, you fit yourself.
What happens if the internet goes down?
The TH Elite keeps controlling the heat lamp with the settings it has stored. The plug keeps the schedules already set, as stated by the manufacturer. Notifications, history and remote control resume once the connection is back.
Can I add more devices?
Yes: in the same eWeLink app you can add more Sonoff plugs for misters or daylight lamps, and a second TH Elite with its own probe for another terrarium. For heat mats or heating cables, write to us from the contacts section.
Are there batteries?
No: the thermostat, the probe and the plug are mains-powered. The probe draws its power from the TH Elite through its own cable: there are no batteries to replace. It is just worth keeping the probe clean and away from direct mist.
What if a product is out of stock on Amazon?
Write to us from the contact page quoting the kit code: we will point you to a compatible alternative, checked against the other devices just like the rest of the kit. Avoid swapping an item for a similar one without checking protocol, power supply and type of connection: a different model may not work with the rest of the kit.
Why buy on Amazon?
Purchase, delivery, returns and warranty are handled by Amazon: you will see the times and conditions on Amazon at the moment of purchase. The kit itself is ours: we chose the parts, checked that they work together and wrote this installation guide. The link opens the cart with every item already added.
