To connect to your Shelly Plus H&T, connect your device to the Wi-Fi network with a name(SSID) like ShellyPlusHT - 7C87CE6CE174. 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 Plus 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 Plus H&T.
General - Home page
In the web interface, you will see five icons at the top of the screen, including one for AP, Wi-Fi, Bluetooth, Cloud and MQTT connection. Here is what the different status colors mean:
Gray: AP mode is disabled.
Blue: AP mode is enabled.
Gray: Wi-Fi connection is disabled.
White: Wi-Fi connection is enabled, but not established.
Blue: Device is connected to Wi-Fi.
Gray: Connection is disabled.
Blue: Connection is enabled.
Gray: Connection to Shelly Cloud is disabled.
White: Connection to Shelly Cloud is enabled, but not established.
Blue: Device is connected to Shelly Cloud.
Gray: MQTT is disabled.
Blue: MQTT is enabled.
In the home page of the Web Interface, you will see the temperature and relative humidity readings as well as the battery of the device.
From the drop-down menu, select the temperature unit, which will be used to display the temperature on the device's display. You can choose either Celsius or Fahrenheit.
Temperature delta 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.
Humidity delta threshold
Set the humidity threshold in percent, which will trigger a device wake up. You can type in a value between 1% and 20% in the text box. Relative humidity change with more than the specified value triggers the device to report sensor data. To save the changes, click Apply.
Use events to trigger http endpoints. You can add up to 20 webhooks. Create a webhook:
Set webhook name.
Active time: May leave as the 24-hour default option or choose an active start and end time.
When: Select from a variety of conditions for the button/switch.
Add URLs: Input URL to send the Shelly device a command. You may add up to 5 URLs per webhook, which will be executed one after the other.
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.
To change the name of your device, simply type in your desired name into the text box.
In this setting, you can see your device's ID, Firmware version and build ID, as well as the Web build ID. You can also see the available new versions, check for updates and easily update your device. There is also an option to upload your own firmware, however flashing devices with custom firmware irreversibly voids the device warranty.
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.
By clicking the button Reboot under this setting, you can reboot your Shelly device directly from the Web Interface.
If you want to bring your device's settings back to how they were originally, you can click the button Reset Device to reset the device to its factory settings.
If you enable authentication, you will be asked to type in a password, which you will then use to access the Web UI of the device. Once enabled, to disable it, click the toggle and enter your authentication pass once prompted.
This setting includes Mqtt, Websocket and Udp debug. To enable any of these, click the toggle switch next to the specific setting. For Udp debug you will also be asked to type in a udp address.
In this setting, you can connect your Shelly Plus H&T to your home network by selecting a Wi-Fi network and typing in its password. Enable Wi-Fi 1, or Wi-Fi 2, or both at the same time. If both Wi-Fi 1 and Wi-Fi 2 are enabled, and the Shelly device disconnects from one of the networks, it will connect to the other. When connecting your device to your home network, you can also set a static IP address for your device to acccess it at.
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.
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!
Disable/enable Bluetooth by toggling the switch. The device's default Bluetooth setting is enabled.
Configure the Shelly device to execute actions via MQTT. By default, MQTT is disabled, but you can enable it by toggling the switch. Changing these settings will cause the device to reboot. There are some other settings, such as RPC status notifications over MQTT (which enables you to communicate with your device through RPC notifications) and Generic status update over MQTT (to get an overall status update), which you can enable/disable by toggling the switches on their right. You can also enable SSL and type in your server, username and password, but be aware that enabling SSL will hurt the battery life and most likely shorten it by half.
In the Connectivity setting, there's a button Choose file, where you can attach and upload a User CA Certificate.
