If you do not plan to send the collected data to the Level2 server, select "Do not send" in the "Send current values of registers" and "Send interval of collected data" items. The more frequent the sending of data, the greater the consumption of Internet traffic (actual for 3G connections).

Click "Save".

After that, your WebHMI will be able to send SMS messages to Telegram. Sending SMS - the service is paid, works with a prepayment.

For registers that have the "Send log to WebHMI Cloud" option, the accumulated log will be sent to the Level2 server. For registers that have the option "Send the current value to the WebHMI Cloud", the current values will be sent to the Level2 server. The frequency of sending these values can be configured on the page '' 'Configuration-> System settings' ''.

Note that after the project restoring from the backup, the system automatically unchecks Enable integration with cloud solutions. It must be turned on again manually. This is done to prevent accidental data sending from WebHMI which you restored the project for debugging or development purposes.

After checking "Enable integration with cloud solutions" checkbox and entering the correct key, the system will start to export its settings in the background to Level2. With a large project this may take some time. Therefore, there are situations when the data in Level2 is not displayed immediately. Wait a few minutes after you turn on this option for the first time.

In the future due any change in the project, the system will update its parameters in Level2 itself.
