Charge Anytime and Ohme Home Pro kWh usage figures don't match

Thanks for the post, @Dark.

I’m keen to hear what other Charge Anytime Ohme smart charger customers say about their credits and usage figures. @mirving123 is one we know of. 

If you’re convinced of an error that needs OVO to look into, email the OVO Smart Home team on: smarthome@ovoenergy.com

For anyone else keen to learn more about Charge Anytime:

I did email the Smart Home team initially on 3rd Mar and was told that because Ovo is gathering 3rd party info from the charger there may be some delay and that “Typically any misinformation is updated within 2-5 working days.” However Ohme support - who are very responsive - tell me that the charger will “send the data across normally within the hour of the session completing”. I’ve asked smarthome@ovoenergy.com to look into the discrepancy but still waiting for an update.

As a follow up to this, I just unplugged the Ohme to make a short journey BEFORE the scheduled overnight smart charging session had kicked in. When I returned home and plugged back in again I checked the Ovo account page (as I have been doing obsessively for the last week). I was pleasantly surprised to see that the charing credits now appear to show usage from my last actual smart charging session several days ago. This was the first time I had plugged in since that session.

Looking at previous behaviour regarding kWh consumed vs what is showing in the Charge Anytime credit looks to me like the Ovo Charge Anytime credit is one charging session (or at least one plugin) in arrears!

I will continue to monitor and am still interested in what other users are experiencing.

@Tim_OVO @simong and also @Blastoise186 in case you are interested

I am finding that there is little correlation between the cost and kWh shown in my Ovo account, and that within the charging stats of my Ohme app. The reported readings are much higher (currently about 1.5x - 2x higher) in Ohme compared to the Ovo account. I have done about 3 charges so far since switching to Charge Anytime so it will be interesting to see how it progresses over the course of this month. At the moment it could be that Ovo is one charge behind, but too early to tell as I will need more charge cycles to get a better understanding and see if there is a pattern to it.

Still a disparity on mine. If I look at My Cars Cost in my Ovo account it shows £2.85 and 28.4 kWh for March, where as in my Ohm app for March it shows £4.46 and 44.6kWh.

It would be good if when you clicked ‘See the Breakdown’ in the Ovo account it actually gave you a breakdown of each charging session with the costs and kWh used each time you did a charge. This could then easily be compared to the individual sessions in the Ohme app.

Is this Ohme figure of 44.6 kWh just for usage during Smart Charging sessions? Have you max charged / boost charged at any point or used preconditioning as I think this will show in the Ohme app totals - at least it does for me - but isn’t included as part of the Charge Anytime credit calculation. I agree that the breakdown of each charging session in the Ovo account pages would be very useful and I’ve no idea why they’ve chosen not to show this. 

I have not done any boost charging or preconditioning, all 3 charges this month have been smart charging only. Not sure what you mean by ‘max charged’? I have set a schedule on the Ohme to reach 100% by 07:00 each day. My wife doesn't let the car get too low on charge, so when plugging in around 6pm, it only needs 2-3 of hours to reach full charge during the smart charging period (which seems to be from 10pm typically).

Max charge is just the feature on the Ohme that overrides the charging schedule and just charges to full as quickly as possible - you can activate it through the Ohme interface. Its same as boost charging.

This is great feedback and insight. If anyone else new to Charge Anytime can share their experiences this is a good place to document them and I will continue to make the teams aware!
