A while ago, a few lost their meter connection due to a faulty update. Most we’ve heard from now have things back in place but I found reporting missing data to Hugo (or Hildebrand if you have the Bright app) dug into the issue. 
Your connection to the IHD is via a different link to that for the main data feed the supplier uses (goes via DCC)

Thanks have messaged Hugo. Fingers crossed.

This has started to get some results but the issue today is that the gas data has showed up but it says that there is no meter reading.  Does anyone know why there may be a discrepency?

It’s too early in the day yet - try again after 4pm.

When you look at data for gas, it takes a while for the calculations needed to convert from cubic metres to kWh (which needs a calorific value only published after the event).

Often your gas data (unless estimated) will not show until later the day after the usage

Hey @Michael1696 

BPLightlog has given a really helpful explanation here. Just wanted to add the following which you might find interesting:

Every so often I get gaps in the display of Daily Usage. Whilst it has a kwt and £ for the full day, there is no daily breakdown at times. It’s infrequent. It might only be 3 times a month but it concerns me. When this occurs the App would say  “data is on its way” but it doesn’t arrive. I look back on Jan and Feb and there’s a few days which still say “data is on its way”. 

It happens, sometimes more than others, some people never see it, others see it a lot.

It happens because of a glitch with the radio signals between the smart meter and the company requesting the data. There can be many thngs that might cause a glitch.
The meter has the data and keeps it (for the last 30 days I think) but after a number of days the company will stop trying to ask for it, it isn’t really needed as long as they have later readings.

In the end it doesn’t realy matter if a day or more goes ‘missing’ what counts for your billing is what your meter says at (or near) the start of your monthly billing period and what it says at (or near) the end of it.

As long as they have meter readings from ‘near’ the start and end of the billing period then they can estimate the rest from those. (Or can just estimate the whole month if they have no readings at all).

That’s what you will see displayed for the Full Day when there is no half hourly data showing - an estimate.
(If they do get the data later then it will show up and that estimate will get corrected).

If they can’t get any smart readings at all then they will ask you to read the meter and send the readings in yourself, just like you have to if you don’t have smart meters.

It’s easy to send in readings, you can do it online, or in the app, or by phoning support, or by webchat.
However you don’t need to send any unless they ask you to. (Although you can if you want, before I had a smart gas meter I would send the gas meter reading once a week).

I can see my IHD showing a blank display time by time, which I understand happens when the meter cannot connect to the network. It usually happens around midnight. But in general, from what I can see, it doesn’t affect my bills. As ​@Nukecad said, the meter stores all data and sends it away once the signal is back.

Hi ​@Adin Ath, and welcome to the OVO Forum 😁.

Some really helpful replies from ​@Nukecad and ​@costeek - thanks both. 

​@Adin Ath I have this problem myself sometimes. Sometimes the smart meter signal will be affected by things outside your, or OVO’s, control. If the smart meter ever stopped communicating for any length of time then our Support Team would diagnose the issue, and repair it remotely (if possible), or book you an appointment to have the meter replaced. Most of the time smart meters will just start functioning again as normal after a period of non-communication.
