Help! We had a scheduled power cut of 7 hours or so 2 weeks ago, as Northern Power needed to work on nearby cables. Since then the IHD is not receiving data. Called 4 times now, followed all reset instructions and engineers have done something remotely(?) still not working. The last call today I was told that the unit is out of warranty (only by 2 months!) and that they would not replace it, that I can track on the app or buy a new IHD at £50.00 Well, you can't track real time on the app can you - really disappointed with the response, we are encouraged to get display units so that we can save energy and monitor our usage! If any of you have any ideas please let me know. Thanks in advance

Afternoon @PipB Welcome to the forum. Have a little look at this thread :

Although this problem wasn't caused by a power cut there are some hints and tips that might be worth considering.

Thanks will have a read 🙂

@PipB If you still have problems then pop back with all your info on what type of meters, IHD, and comms hub you have. Also the status of the HAN and WAN lights on the comms hub, colour and flashing frequency. May even be worth popping up photos of your meters, IHD and comms. Then may be some of the very learned members might be able to advise.

@PipB
I’m sure that your problem lies with the Global Unique Identifier (GUID) registration of your IHD with the comms hub (CH) having been lost during the power cut. The power cut would not affect the IHD itself which runs from a battery

I think that EOn (& other energy providers) either

1. don’t really know the answer, or
2. know that the solution probably requires a commissioning engineer visit

So in both cases take the easy option of blaming the IHD, which in a lot of cases is probably out of warranty so no longer their responsibility

Having seen so many posts complaining of IHD’s losing connection, or stuck in “waiting for current data” loops, I’m positive in the majority of cases that the issue lies with the CH and not the IHD

This document details the SMETS2 commissioning process – page 9 describes the commissioning of the IHD. The engineer uses a “toughpad” (presumably some kind of tablet) to enter the GUID of the IHD which must be stored in the CH (allowing only this IHD to join the HAN). Whilst this is being initialised, the IHD is sitting in a waiting state until the process is complete and a successful connection is made.

So if the CH loses the GUID details of the IHD, it will no longer allow the previously functional IHD to join the HAN, so the poor lonely thing just sits there waiting😥, but just gets ignored by the CH which no longer recognises it.

Yes, a ruggedised 'thin client' Windows CE tablet, made by Panasonic.
