Feed data display delayed

I have a powertokWhd (112058) feed which is behaving odd since yesterday. It is showing data with a delay of one day. As I download data for a terminal display with the ESP8266 to show power consumption for the current day and the past 7 days using JSON GET commands using the Input API, this has also messed up with the readings. As it has always worked for me, I was wondering if there is something different with the API these last couple of days.
