My I've display shows peak rate for all usage even though I have the ev charging app. Are there any other IHDs that show the correct use

The rates shown on all IHDs (Ivie Bud; Glowmarkt; Smart view etc) are just the rates which are present on the meter itself

The IHDs just report/display the data which is held there, so unfortunately they rarely show both rates for the Next Drive tariff

For a while EON had somehow uploaded both rates to my meter and the IHD showed the rate at the relevant time. Unfortunately the times related to the Economy-7 E7 timing, not Next Drive timings

Yes I've had the official blurb from Eon saying dual rates aren't possible. This of course contradicts IVE website which says it is. Sounds as though it might be made to work if Eon sends the right message. I think this is in the too hard category

Hey there 👋 @Barrieb

Welcome to our Eon Next Community and thank you for reaching out here. 😊

I can see you've mentioned you're currently on the Next Drive Tariff, and at the moment the IHD unit is not able to display the off peak rates due to the way the billing for the next drive works. The best way to view these would be your actual statements or the meter itself.

It's down to how E.on update (or rather don't) the meter tariff matrix to match the billing. If they did so, the IHD would display the correct prices and costs.
Viewing on the meter won't help - that is the issue - it doesn't have the correct tariff matrix loaded and the IHD is just a repeater of that.

Other suppliers manage it, as do E.on on occasion, but have instead chosen to hide behind a get out clause in T&Cs, rather than actually make it work for all customers.

@rwh202 - I wonder if the issue is more global with the latency of command processing with the Smart/DCC infrastructure.

Truly dynamic tariff refresh would require ½ hourly updates, and more static ToU would require daily updates for the next-day prices.

However a Google for "what is the latency delay in processing DCC service requests" returned this, so it could be that the system just can't handle a huge amount of update requests 🤔

@geoffers - Yes, it might be impractical for the ‘dynamic’ tariffs, but for standard drive and the fixed smart saver tariffs, no different than economy7 needing one update a year - less than the SVR!
