The Shelly H&T is a compact smart WiFi-enabled temperature and humidity sensor, which can be remotely controlled and monitored through a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. Shelly H&T can be accessed and monitored remotely from any place where the user has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet. It also has an embedded web Interface, which can be used to monitor and control the device, as well as adjust its settings. Powered by a single CR123A lithium battery (battery not included), the H&T can run for up to 1 year thanks to its low power consumption. Once connected to your Shelly network, you can use it with your Shelly smart home ecosystem, including the Shelly Smart Control app for temperature and humidity log data - or link it with a popular home automation software such as Home Assistant via a Raspberry Pi!
