Connectivity issue with my Chameleon In Home Display (IHD) and how I fixed it!

Updated on 23/10/25 by Ben_OVO

 

Since we had S2 smart meters installed for gas and electricity last year, we have lost the electricity readings on my IHD twice. The engineer came round and replaced the electricity meter a couple of weeks ago, but the electricity readings stopped again after a few days. OVO have said that it is a firmware problem in the IHD, and a replacement will be rolled out after January.

Wondering if the IHD can be reset to temporarily fix the problem, I pressed the on/off switch and disconnected the charger (My IHD seems to have a battery in it so it works when disconnected from the supply). I then held the on/off switch pressed for some time while reconnecting the charger.

The IHD came up in a reset condition and reconnected to both meters after a minute or two. It is now showing both gas and electricity readings again. So if it fails in a few days, which I expect, I now know how to get it working again. I presume that there is some sort of software overflow problem which works for a time from reset and then fails. It would be interesting to know if this works for others having similar problems. The unit is a Chameleon and it says "type 2" and "IHD3-PPMID / CA30111" underneath.

      My Gas and Electricity Smart meters were installed a week ago and although my monitor was working perfectly for the following 3 days it then lost it's connection. Since then, I've turned it off and on next to the meters and although signal light in the top left hand corner flashes on and off, I still receive no information...does the IHD3 need re-activating by OVO?

      Take a look at this topic for more info, @brickbrad, let us know how you get on!
      My friend told me how electricity is measured and I was like Watt!

        Hi @Barney

        You were lucky. My IHD reset only worked for a while - have had many more problems, as discussed in this thread, but after the last meter install and firmware upload all is still OK:

          Hi
          the electricity readings on my IHD failed to display about a week ago but have inexplicably returned over the last 2 days.
          However my gas prices are WAY off. It’s showing that I am using £1 per kWh. Yesterday I used £17.60 and I wasn’t even at home until 7pm.
          However the web pages cost looks correct.
          I reset my IHD settings but it didn’t shut down. It just sits there frozen. A paperweight might be the best idea. I have unplugged from mains to let the battery die out and see if it will reboot if I then connect to mains. If this continues I’ll switch to another provider that supports the meters and who is more efficient in rolling out fixes.

          So it died pretty quickly and I’ve charged it a little. Total monthly cost looks right now ( Ive had it installed about a week)but no individual cost for gas, only electric. And I’ve never been able to see the tariff information.

          Hi @tonyw707

          It seems you have to be patient, and OVO eventually will sort it out. My IHD has now been working correctly and the website is correctly showing my usage for at least a month. The posts on this forum go a long way to explaining why it takes so long - unfortunately, there are a lot of government imposed systems involved in the SMETS2 jungle:
          https://forum.ovoenergy.com/smart-meter-booking-and-installations-66/smart-meters-not-worth-the-pain-6858/index3.html

          Don't desert OVO - they seem to be trying as hard as anyone to make it all work.

            Hi @tony1tf

            Thanks for the advice and the link above. The IHD seems to be working okay today since the reboot this morning so fingers crossed it’ll stay that way. I guess what’s most important is that the meters are correctly sending readings to OVO. Still, it’s a bit alarming to wake up and find out you’ve apparently spent £50 on gas you know you couldn’t possibly have used. Reminds me of when I had a brand new gas meter from Npower and the next month they charged me £13500 for the month because the readings had seemed to go around the clock haha
            I’ll keep an eye on it and see how it goes. Thanks again
