Why has my usage data from my smart meter not updated on my online account for two days?

Updated on 10/10/25 by Ben_OVO

The online account / app usage graphs are a really useful tool. You can find out how to use them in this guide:

If the usage is missing on your online account or OVO app (download for Android or iOS) this is usually caused by a temporary communication issue with your meters which could result in the following effects on these usage pages.

Please note that, in order to see daily and half-hourly usage, you’ll need to set the reading schedule of your smart meter to half-hourly. You can do this via your online account / app by following this guide:

Half Hourly usage data missing 

This section can be missing data if something happens to prevent the smart meter sending your reading for a time. For any missed half hourly periods, the usage will be averaged out once comms has been restored. This shows as a number of bars being the same size. 
 

Daily usage data missing

This section can also see communication drop outs, even if there’s half hourly data available that day. It needs a reading at around midnight to be able to populate that day’s usage. If you’re seeing missing usage for that day, see if any of the half hourly bars are missing for the end of the day. Communication is usually restored by itself, and any missed daily periods will be averaged out when this happens. This shows as a number of bars being the same size. 

If the usage data hasn’t returned in a few days it might be worth completing a smart meter health check for your meter type below and contacting our Support Team with the results:
