Hi everyone,
I would like to know if there is a method to show if my sending device has been disconnected or went offline or showing data is too old.
example : my sending device has interval of 60 seconds and if last count was like 15 mins old I can make an event so I will react upon it.
because my receiving device dose not know if my sending unit became offline and it will keep displaying the last value no matter how old. and maybe make it as indicator on the dashboard as online offline .
Best
Juma
