How can I correct this problem in the ploting?

[DrMoe]

Hi all,

I would like to graph the Energy consumption for my Shelly products, the problem I am facing is that with every System reset or Shelly firmware update the KWh consumption is reset to zero (see in the attached picture). Is there a way to resolve this issue?

Any help/tips would be appreciated.

Thanks!

Shelly - Power Meter resets total consumption on power loss

Not quite. What you need to do is keep track of the last reading from the device. if(currReading < lastReading) tcp = tcp + currReading else tcp = tcp + (currReading - lastReading) The first reading after the reset will treat the currReading as the delta to add to your running total. Every reading after that we add the difference between the current reading and the last reading to the running total.
