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.
