Product Introduction

Shelly® is a line of innovative microprocessor-managed devices, which allow remote control of electric circuits through a mobile phone, tablet, PC, or home automation system.
Shelly® devices can work standalone in a local Wi-Fi network or they can also be operated through cloud home automation services. Shelly Cloud is a service that can be accessed using either Android or iOS mobile application, or with any Internet browser at https://home.shelly.cloud/. Shelly® devices can be accessed, controlled, and monitored remotely from any place where the User has internet connectivity, as long as the devices are connected to a Wi-Fi router and the Internet.
Shelly® devices have an embedded Web Interface accessible at http://192.168.33.1 when connected directly to the device access point or at the device IP address on the local
Wi-Fi network.
The embedded Web Interface can be used to monitor and control the device, as well as adjust its settings.
Shelly® devices can communicate directly with other Wi-Fi devices through HTTP protocol.
An API is provided by Allterco Robotics EOOD.
For more information, please visit: https://shelly-api-docs.shelly.cloud /#shelly-family-overview. Shelly® devices are delivered with factory- installed firmware.
If firmware updates are necessary to keep the devices in conformity, including security updates,  Allterco Robotics EOOD will provide the updates free of charge through the device-embedded Web Interface or Shelly Mobile Application, where the information about the current firmware version is available.
The choice to install or not the device firmware updates is the user’s sole responsibility.
Allterco Robotics EOOD shall not be liable for any lack of conformity of the device caused by the failure of the user to install the provided updates in a timely manner.
Shelly Plus H&T (the Device) is a Wi-Fi smart humidity and temperature sensor.

Installation instruction

⚠ CAUTION! Do not use the Device if it has been damaged.
