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

Since we had 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

Nice work sorting this @tony1tf

Keep a look out for anyone else with this issue!

If I spot one, I'll send them to this topic!

Hi @Tim_OVO

Unfortunately this method is not foolproof. I have also found that deleting settings turns off the IHD. When you switch it back on it finds the meter(s). However, for the last couple of weeks it has only been able to find the gas meter, even when a couple of feet away. So I am still awaiting the new firmware hopefully to get round this problem.

This topic might be worth a look @tony1tf

HI Tim

Ufortunately that reply referred to the older meters. Smect2 don't have a keypad, and the lights are diffetent. Bizarrely, my IHD has started showing gas and electric readings again in the last two days. I wonder if OVO have managed to do an over the air firmware update?
I find that if I unplug my 'connection lost' IHD it makes a great paperweight, about all it's good for!

This update was scheduled for the end of January to start of Feb, so it sounds like it's worked!
Sadly the problem persists. We had a new Smect2 meter installed last month. The IHD worked fine for a few days,. then it lost connection with the meter and now just shows "Waiting for current data" and the wifi fan top left blinks.

According to OVO who I spoke to today there is still a problem with the IHDs and there is a 5 week wait for a replacement!

I have tried Tony's method of rebooting but to no avail. Just get the above message.

Pretty disappointing. What is the point of a smart meter if it does not connect to the IHD?

If there is a reboot method that works I would love to hear about it.

My display is showing my joint usage yesterday as £75.84 but with 65.63 kWh Usage. If my tariff is only £0.15 per unit and £0.036 per kWh how can these figures be anywhere near correct?.
I am having the same trouble with mine says I'm using £15-£20 a day! But when I go to total bill for period it was I've used less than £10... anyone know how to fix this?
I have exactly the same problem, readings in KWH are correct but price is ridiculous. My question is: Is anybody's Chameleon IDH3 giving the correct price for the KWH consumed, I think gas looks about right but electricity is way off.

Hey, @mattbuk33, @Bencie09, and @andyt63 I've moved you collective posts here.

Please check out @tony1tf's post at the top for the answer you need.

Thanks!
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?

Hi Tony just read your post regarding the IHD “freezing” as my IHD did the same last night followed your remedy & it worked ok this morning so everything crossed.Thank you for sharing that information.👍👏😊

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:

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

Tony

I have a Bulb account with a newly installed smart meter which has just stopped working completely after about two weeks. I started searching and found this forum and thread, and tried the fix mentioned in the first post. This is to let you know that the fix works for other meters! From the start the meter failed to show gas readings but was fixed within 2 to 3 days of complaining, although they never replied to my message other than an automated “did this help” message (which didn’t).

These things are so bad they are not worth the plastic they are moulded from.
