After a month of my 3EM being working fine, the daily consumption history started to gain an ever greater delay at the time, even having more than 5 hours of delay. For example, when it was 20:00, the history showed the current reading at 15:00 and the next day an even longer delay.
To try to solve the problem I executed an "erase data" and as the problem continued I did a factory reset.
Thee problem seemed to be solved for 4 days and then it happened again.
Can you help me?
