I noticed that today, from around 13:30, my IHD lost its connection to my WiFi (well, the realtime datafeed had stopped and the wifi symbol on the IHD had disappeared). The IHD was still connected to the smart meters though, so was atleast still displaying some data.
Initially I tried re-associating the IHD with my WiFi, but this had no joy, but I could see the device on the network, I could ping it, so I know it was connected, so thought I'd do some digging to see if it was an issue with the IHD, or ovo...
So first task (as I could atleast ping it) was to just double check the WiFi connection, so I did a debug output from my wireless controller against the client MAC of the IHD, and could see it associating just fine, it wasn't dropping the connection or timing out.
Next up a packet capture, and first off I could see the following:
Somewhat odd that it was continuously performing ntp queries, but I have noticed that (previously) at midnight the totals, realtime consumption amounts, etc, would all reset at midnight, and be correct, but since the clocks changed, it would reset at 1am instead, and consumption amounts have been out by about an hour as far as the IHD is concerned. So, possibly related? No... A quick check to see what time-c.nist.gov was returning in the packets shows the time is waaaaay out:
So as a quick fix on my side, I've added a host override for time-c.nist.gov to resolve against my own ntp time server, and since doing that, the IHD has connected fine, and is now feeding realtime consumption back to ovo. As a test, I disabled the override and again the IHD failed to transmit realtime data, disconnected, and got in a loop querying time-c.nist.gov.
So, is this something which needs raising to the manufacturer of the IHD? Or is the ntp configuration something you're able to remotely update? From what I can tell, the entire nist.gov ntp stack is having issues, so would it not be more reliable to use pool.ntp.org instead?

Called the cs team and they say there is a known issue. They stated it was linked to live data not being displayed because of an issue on the box. I wasn’t put through to anyone technical so not overly convinced my issue is the same. They say the tech team are looking at it and I should get a response in 10-14 working days! As that’s potentially nearly a month I guess I will just have to wait and see. I was told it might been they need to send a new ihd out.
I’ve got the latest ihd, we only had it around a month ago.
