The Shelly H&T Gen3 Mocha is a WLAN-enabled temperature and humidity sensor designed for monitoring indoor climate conditions in living and working spaces. The device precisely measures ambient temperature and relative humidity to ensure healthy and comfortable living conditions. It is part of the Shelly Plug&Play series and enables seamless integration into existing smart home systems without requiring an additional hub. Control is possible via the Shelly Smart Control app, an integrated web server, or various home automation platforms, with support for voice assistants as well.

Applications
This sensor is particularly suitable for monitoring living rooms, children’s rooms, bathrooms, or other areas where humidity and temperature affect health and well-being. It can be used, for example, to prevent mold growth in bathrooms or to ensure a comfortable sleeping environment for babies. By connecting with other Shelly devices, such as the Shelly Plug, intelligent heating control can be implemented, automatically activating the heater when the temperature falls below a predefined threshold.

Features and Specifications in Detail
The Shelly H&T Gen3 Mocha features an E-Paper display with low power consumption, showing current measurements while extending battery life. The integrated clock enables timestamping of measurement data. The device can be powered either by four 1.5 V AA (LR6) batteries or continuously via a USB Type-C connection. Battery operation ensures a lifespan of over one year, while the USB connection allows for faster connectivity and more frequent data transmission. The device is wall-mountable, offering flexible placement within a room.

Technology Explained Simply
The device operates via WLAN, connecting to the local network to transmit measurement data to the Shelly Cloud or other control platforms. It includes an integrated web server, allowing direct configuration and monitoring via a web browser. Firmware updates are available through the web interface or the Shelly Smart Control app, with updates provided free of charge by the manufacturer. The new Shelly chip with 8 MB of memory ensures faster responsiveness and smoother operation, while also supporting future features. The Bluetooth connection enables quick integration into the home network or use as a Bluetooth gateway.

Compatibility and Accessories
The sensor is compatible with various home automation platforms and can be combined with other Shelly devices, such as the Shelly Plug, to create intelligent scenarios. Connectivity is via WLAN and Bluetooth, with no additional hub required. Voice assistant integration is also possible, provided the platform supports it. The device can also operate as a standalone unit without relying on external services.

Installation and Mounting
Installation involves inserting four AA batteries or connecting to a USB Type-C power supply. The back of the device can be opened with a flathead screwdriver to insert the batteries. Battery polarity must match the markings in the battery compartment. When using the USB connection, ensure that the cable and adapter are not damaged. After powering on, the device automatically enters setup mode, which transitions to sleep mode after three minutes. The reset button can be used to re-enter setup mode.

Operational Advantages
The Shelly H&T Gen3 Mocha offers a battery life of over one year when operated with AA batteries, enabling low-maintenance use. The combination of WLAN and Bluetooth ensures flexible and reliable data transmission. The integrated clock and E-Paper display provide detailed and energy-efficient visualization of measurement values. The option to power the device via USB Type-C adds extra flexibility, especially for continuous use or in areas with high data transmission demands. Data storage is available free of charge for up to one year, enabling analysis of trends and changes in indoor climate conditions.
