Lost Connection - Smart Meters not sending meter readings and no data on In-Home Display (IHD) - Why?

My Smart Meters (Electricity+Gas) were installed 1 week ago along with an In Home Display (IHD). The IHD on day 2 lost connection and I have not been able to get it back since. I have gone online and confirmed that no readings are being sent so at present there is nothing smart about it, unfortunately. The Smart meters do not come with any instructions neither does the IHD (in-built tutorial is basic only). Pressing 9 on the Electricity meter turns the digital display on (they have power saving displays) and presents the data you would expect to see on the IHD e.g. used today, used last week etc. There are no issues with my Wi-Fi. I have gone on-line to reset my browser and that doesn't work. I have used WPS and manual key entry to connect the IHD to my Wi-Fi and although it recognizes my ISP (~Sky) it is still not working. Currently, I'm unsure if it is not connected to the Wi-Fi or if it cannot connect to the meters themselves (instructions would help). IHD is within 20 metres of the Smart Meters and within Wi-Fi range. I have fixed bars on the IHD. Question: How does a user get their IHD reconnected or confirm Meters are not working properly?

If you’ve noticed an issue with your Chameleon In-Home Display or the communication of your smart meters follow the advice below to help get any technical bugs ironed out! :bug:

 

If the IHD has been working as it should, but has suddenly stopped showing usage data, then the best thing to do is contact our Support Team and request that they run an ‘XJOIN’. This is a remote request we send to the IHD to get it showing the usage again. You can find the contact information below:

 

 

Newly installed Smart meters
 

Whilst most devices are up and running from the date your new meters are installed, it’s not unusual for them to lose some data or experience teething issues as we carry out the initial work to get everything up and running.

 

We’d recommend keeping the device plugged in close to your electricity meter if you notice any issues during the first 6 weeks following a smart meter installation. Hopefully things should start working as expected once the smart meters are fully updated on your account but, if not, read on to check our next trouble-shooting steps.

 

Checking the smart meter connection (WAN) via your online account or OVO App

 

Been over 6 weeks since the smart meters we’re installed and you’re still noticing issues with your Chameleon device? - It’s time to start doing some investigating! First place to check is your online account or OVO app (download for Android or iOS). If we’ve lost connection to your smart meters for over 5 days you may should see a message on screen asking for a reading.

 

 

In this case the best next steps would be to carry out a smart meter health check for your meter type below:
 

 

 

Once any communication issues with your meters are resolved, we’ll be able to get your IHD connected and showing your usage data again too!
 

In the meantime it’s worth submitting a meter reading a few days before your next monthly summary is due. 

 

To take a reading you’ll need to go to the meters themselves (this won’t be viewable on the In Home Display unfortunately).

 

For SMETS1 ‘Secure’ smart meters:

 

There’s a slight difference between these S1 meters depending on whether you’re on a single rate or Economy 7 tariff. To take dual (day/night) readings on a Secure Liberty 110 , press 9 on the meter’s keypad. If you’ve got a Secure Liberty 100 S1 smart meter, press 6 to confirm the Day and Night meter readings (pressing 9 will show the reading if you’re on a single rate tariff).
 

For SMETS2 Aclara, Flonidan, Honeywell or Elster smart meters:

 

  Aclara (Elec) / Flonidan (Gas) Elster (Elec) / Honeywell (Gas)
Reading the meter
  • Elec: Press A three times until TOU Rate 1 appears.
  • Gas: Press C to wake up, then C to access the menu. Use B to scroll and C to select the reading option.
  • Elec: Press the top button once or twice
  • Gas: Press the circle button once or twice

 

You can then enter this reading by clicking ‘Send a meter reading’ on the Homepage message or by clicking on the ‘Meter Readings’ menu option.


Fingers crossed those smart meters will be back in touch soon and you can continue enjoying all the great benefits of going smart:slight_smile:

Thanks. They say they have requested the data manually, but it hasn’t worked. 
 

When I asked why I was able to see all the data, they stated that the health checks show that they have no connection with the comms hub so there is no indication that there may be a different issue elsewhere.


They also said they have also requested the data from the DCC however this takes slightly longer to come through than directly from the meter. 

 

Do I keep persisting?

Suppliers don’t have direct contact with the meter - it all goes via DCC.

If you want to get to the bottom of things, I would keep asking.

Thanks. One more question - When I go to the n3rgy smart meter check (https://homebrew.n3rgy.com) there is a message at the bottom saying:

”Cache: 2025-01-15T21:04:15.186Z [cached]” 

What does it mean? This is around the time I first visited the site, so am wondering does it mean the site can’t currently connect to the meter, so is using a previous cached version?

When you visit that site, it ‘records’ the result. So what you are seeing is from that time slot. 
I don’t think it necessarily means that it can’t connect.

Is there a way to get it to refresh?

I’m not sure. I thought it would be a local cache on the pc but I’ve just tried on my own data, cleared the web cache but it still reports an earlier result

My electric smart meter is not sending readings and no electricity data is being displayed on the IHD. The gas reading are being sent and is being displayed on the IHD. The SAN and LAN lights on the electric meter are flashing every 5 seconds which according to the help page means they should be fine.

Please check your online account:

  1. On the Profile page, click View settings under Set how often meter readings send. On the page that opens, make sure both of the half-hourly options are selected. There’s an industry wide change coming to meter reading consent, and we want to share the details with you | The OVO Forum  
  2. Open the Usage pages and look for data on the Day tab for recent days.
  3. On the Meter readings page, click the View reading history buttons in turn to see what readings are being received.

Reading are set to be sent every half hour, the electricity reading was sent by smart meter until 24th January after that I've sent in manually each week.

That’s a job for Support, then, if meter readings aren’t being retrieved. What about usage data - anything on the Month and Day tabs? They may be showing estimates, which should be fairly obvious.

You might try running this little tool that checks how the meter is communicating: https://homebrew.n3rgy.com/ Just enter your 13-digit MPAN and tick the tiny confirmation box before clicking Check meter. You can safely ignore any warnings about expired certification or out-of-date firmware, but any others may indicate where the problem lies.

Last, you could sign up with one or other of the third-party services that can access your meter and retrieve usage data from it. Two popular ones are Bright and Loop. If they can’t get anything either, there’s a bigger problem.
