Charge Anytime app fails to charge vehicle to set max charge level

Sorry I should have been clearer here, it only charges you full standard rate (not the 7p rate) if you over ride and press “boost” (well thats what it on my charger app) then it goes to standard tariff…. 

Thing is OVO don’t really make it clear you can change the end time as often as you want (I guess its not really in their interest to do so) and my (admittedly short) experience is that if I set the “Ready by” time in the near future it starts to charge straight away, so I don’t see me using “Boost” - but I’ve got a PHEV so am not totally reliant on Electricity.  

I have had similar issues. 

I resolved it by removing my car from Ovo Charge Anytime app and then adding it again after restarting the phone.

After that  I uninstalled Mercedes Me from my phone,  restarted the phone and then reinstalled Mercedes Me.

That seems to have worked.....so far!

Although the original post is a year old it is really good to have other views of how to fix issues like this but if it's intermittent you often never really figure out what the problem is. Given the complexity of what has to happen it's not surprising that it goes wrong on occasions.

There are many links in the chain: Your phone and app; your mobile phone signal; OVO’s servers or the servers belonging to the car or charge point; the communications link to your car or internet/lan cable to your charge point; the car itself waking up to a signal to charge or the car deciding it's not the right time to charge. Any of those failing will result in a complete or partial charging failure.

There is not a lot under your control. For persistent problems you can reset the phone, delete and reinstall the app, check the WiFi signal stength between your router and your charge point if you are using that instead of a lan cable, the mobile phone signal strength to the car, making sure you don't have any conflicts between the settings in the car and what you want to do. The latter one can be an issue if the charging times change when there wasn't a problem with the original times but there is with the new times.

The concept should be set set it up and then plug in and forget but sometimes you end up with problems that that involve too many suspects and no way of ever knowing what went wrong.

One source of information worth looking at is the SpeakEV forum for your make of car or charge point.

Good luck!

PS I use a cheap ToU tariff and a fixed timer in the car connected to a dumb charge point. Not quite the cheapest way of doing it but very simple to set up and no failures in 3 years. However, I have chosen reliability over cost.
