I am Using Groov Epic demo kit provided by opto22, and my application is to send the data on MQTT server(that was already done successfully).
Now my further application is explain as below.
when i lost the net connectivity at that time obviously node-red cant able to send that data on MQTT server, but is there any possibility that i can store that data into epic controller or node-red’s any utility or any other way to retrieve that data ??
Kindly suggest any possibilities.
