To connect to your Shelly H&T, connect your device to the Wi-Fi network with a name(SSID) like shellyht- 84CCA87D7CDC. Use the universal IP address for all Shelly devices - 192.168.33.1 to access your device's Web Interface, where you can set a Wi-fi network for the Shelly H&T to connect to. Once done, through the app on your mobile device or through home.shelly.cloud, you can go into the Settings and search for Device information. There you will find the Device IP and be taken to the Web Interface of Shelly H&T.

General - Home page

In the web interface, you will see three icons at the top of the screen, including one for Wi-Fi and Cloud connection, as well as an icon indicating the state of the web interface(passwords protected or not). Here is what the different status colors mean:

  • Wi-Fi icon:

    • Red: Wi-Fi connection is disabled.

    • White: Wi-Fi connection is enabled, but not established.

    • Green: Device is connected to Wi-Fi.

  • Cloud icon:

    • Red: Connection to Shelly Cloud is disabled.

    • White: Connection to Shelly Cloud is enabled, but not established.

    • Green: Device is connected to Shelly Cloud.

  • Lock icon:

    • Red: The web interface of your device is not password protected.

    • Green: The web interface of your device is password protected.

In the home page of the Web Interface, you will see the temperature measured by the device, the humidity reading and the battery percentage of the device.

Sensor Settings

EXTERNAL POWER SUPPLY

Checking the box under this setting enables tou to use and external power supply for your device, i

TEMPERATURE UNITS

Tick either Celsius or Fahrenheit to select the units your temperature will be displayed in.

TEMPERATURE THRESHOLD

Choose a value between 0.5 and 5 from the drop down menu, which will set the threshold for triggering a device wake up. So, when the temperature change is equal to or higher than this value, the device will wake up and send a status update. You can also choose to disable this option. To save the changes, click OK.

TEMPERATURE OFFSET

Set a temperature offset value by typing it in the text box. This setting helps to make the temperature readings more accurate.

HUMIDITY THRESHOLD

Choose a value between 0.5 and 5 from the drop down menu, which will set the threshold for triggering a device wake up. So, when the humidity change is equal to or higher than this value, the device will wake up and send a status update. You can also choose to disable this option. To save the changes, click OK.

HUMIDITY OFFSET

Set a humidity offset value by typing it in the text box. This setting helps to make the readings more accurate.

Internet & Security

WI-FI MODE - CLIENT

In this setting, you can connect your Shelly H&T to your home network by selecting a Wi-Fi network and typing in its password. Enable Wi-Fi Client only, or both Wi-Fi Client and Wi-Fi Client Back-up. If both are enabled, and the Shelly device disconnects from the first network, it will connect to the other one. When connecting your device to your home network, you can also set a static IP address for your device to acccess it at.

WI-FI RECONNECT

If enabled, the device will periodically scan for a better access point to connect to.

Access point

Configure the device's AP, including switching it on or off, and setting a password. The access point of the device is an open network by default. The SSID is unique and cannot be changed.

RESTRICT LOGIN

Once you’ve enabled this setting, you will type in a username and password, which will be used as login credentials every time you visit the device’s Web UI. This setting is responsible for the lock icon in the home page of the web interface and when it’s enabled the icon will be green and the lock will be closed.

SNTP SERVER

SNTP synchronizes your device's system time with a server that has already been synchronized by another source. There is already a set server, which is the default one - http://time.google.com, however if there are any problems, you can easily change it and enter a new one in the text box. Changing this setting will reboot the device.

ADVANCED - DEVELOPER SETTINGS

In this setting, you can enable/disable Cross-Origin Resource Sharing, CoIoT and MQTT. If you enable CoIoT, a text box will appear, where you can type in the CoIoT peer. There you can enter mcast for multicast or ip:port for unicast. A device is required when the CoIoT peer is changed.

You can also enable MQTT, but actions via Cloud connection will be disabled.

CLOUD

Connecting your Shelly to its cloud allows you to control it remotely, receive notifications and updates about your devices. The default for this setting is for the cloud to be enabled. If you disable the device cloud support, you will lose connection to your device from outside its local network!

Actions

Configure the actions for your device - enable, disable, add duration and URLs. The available action is REPORT SENSOR VALUES. You can edit it and type in a URL to be triggered when that action occurs. More than two actions can affect the normal operation of the device.

Sensor URL actions

Configure OVER TEMPERATURE URL and UNDER TEMPERATURE URL - enable/disable these actions, set a temperature value over/under, which the action should occur. OVER HUMIDTY URL and UNDER HUMIDITY URL are triggered when the humidity levels exceed a certain value / drop below a certain value. For all of these actions you can choose whether you want that action to happen repeatedly or only once.

Settings

TIME ZONE AND GEO-LOCATION

Your timezone and location will be autodetected, but you can manually change them from this setting by choosing a timezone from the drop-down menu and typing in your latitude and longitude. There is also a button Auto detect location, which will make the device automatically detect the location once again if it failed the previous time.

DEVICE NAME

Name/Rename your device.

FIRMWARE UPDATE

The device can check for new firmware and you can choose to update it if a new version is available.

FACTORY RESET

Factory resetting the Shelly device will bring it back to its factory settings, disconnect it from all Wi-Fi networks and all associated users, including you, will be removed from the device.

Before you can control the device again, you’ll have to add it to your account again as a new device.

DEVICE REBOOT

Reboot your device.

DEVICE DISCOVERABLE

Make your device discoverable by other devices.

DEVICE INFO

See information about your device, including the device ID, the Wi-Fi network it’s connected to, the RSSI of the Wi-Fi and the debug log. Enabling the debug log without a reason isn’t recommended, since your device will be slowed down and this setting will cause aging of the flash memory. If you do decide to enable it, you can also download the previous and current logs.
