Hello,
We are using cMT SVRX820 for sending Emails in case of plant alarms. Is it possible to get a message (through Easy access or weincloud (Dashboard)) in case the device is not connected anymore by internet!. Any help is useful. Thanks
How do I check if an HMI loses connection to the internet?

Hi @Raptor,
One possible solution, if you have the EasyAccess application running in the background, is to send push notifications when the device goes offline. To do this, open Event Logs:
Then within the Push Notification, clicking on your HMI and adding the Online/Offline option.
Note: It can take a few minutes for the push notification to be sent; in testing it was not as immediate as the Trigger and Recover notifications.
If this approach is not applicable, consider using a heartbeat sensor instead. For example, you could use MQTT or another service to send out a periodic signal from the HMI to confirm it is still online.
Hello AaronS,
Thanks for your reply.
The option within the Easy Access environment we set up. We would like to know if for example there is an option in Weincloud dashboard to report when a device is offline. Or should we use an other service with MQTT?
Thanks again.
Regards.
Hi @Raptor
Dashboard cannot issue a report when a device is offline at the moment. If you do want to use Dashboard my best suggestion would be to keep an eye on the status of tags under the Data Source tab, or look for the offline symbol when viewing your dashboard.
You can use a 3rd party MQTT service, most cloud brokers can determine and give an indication if a device is online or offline.
