Which home wall charger - for a pain free charge?

I've been through a number of chargers. I'm now running an EvBox Homeline in dumb mode and so far, so good. It's a bit big, but OTOH, the internal components look to be of good quality and it provides good compliance with the regs.

I'd reiterate what many are saying here and avoid the smart chargers. You'll miss out on the OLEV grant, but I suspect a good local electrician plus a sensibly sourced dumb charger is unlikely to be much more than an OLEV-funded specialist installer since I suspect that's turning into a very lucrative operation for them.

As regards Octopus Go etc - I think the key thing is to simply use Scheduled Charging in the car to start at 00:30. I wouldn't worry about end time. If you only occasionally go over the 5 hr time slot, then the cost is minimal. If you're going over regularly, then you probably need to look at another tariff.

Yes, as long as you have a Model S or Model X that should work fine, but probably won't work reliably with the Model 3.

It seems that if the Model 3 is sleeping, it will not wake up and start charging when the charge point turns on. If the Model 3 is fully awake when the charge point turns on then it seems it may start charging.

It is a royal PITA that Tesla haven't got around to fixing this, as one of my charge points is timed to come on and off during the cheap rate period, and the Model 3 refuses to wake up and charge when it's in that mode.
Jeremy, your knowledge of these systems is far more extensive than mine. What’s your view on the charging problem, do you think it is software as Tesla claim, or could it be a hardware bug?

Am I right in thinking that you can programme the M3 to start the charge (say 00:30) even if it is asleep but it will only stop charging based on battery level rather than time?

thanks

That's a damned good question!

The fact that Tesla seem to have made no efforts to fix it, in over a year since it was first reported to them as being problem, makes me wonder if it's hardware related. If I had to guess, I'd say that there has to be a way to physically wake the car up from the signal received at the charge port. The logical way to do that is with a hardware connection that wakes up the car, or at least, wakes up the charge control sub-system.

If it was just a software issue, then it's hard to understand why Tesla are taking so long to fix it. There's a counter argument, though, in that if they know it's a hardware problem, then the longer they leave it, the more costly it will be for them to fix it in the field.

The complete silence from Tesla, over what is a pretty significant failing, concerns me, though.

Haven't we seen a communication recently in another thread that was from Tesla saying that it will be rectified in an imminent software update? (Or am I confusing it with the reduced charging rate bug that some people experience on scheduled charging?)

I did have a response from Tesla service saying the reduced charging rate bug would be fixed in a future software update. But then in this future world we’ll all be living on Mars! ;)

I’ve a question on setting departure time. If you set a departure time for 7am, does it only start charging to achieve the desired level for the departure time? Also heat the interior etc.

I stared charging for an hour tonight, went to the car to set the departure time (first time I have done this). The car stopped charging and I left the car and locked. However, 15 mins later I opened the Tesla app and the car started charging. It said stopped when I first opened the app. No mention on the app of departure time.

As I understand it, setting it to charge for a set departure time does exactly as you say. I can't say that I've used it, as, when I owned an i3 they only way to get the car to control a scheduled charge was to set a departure time, and the damned thing wasted energy getting the car preheated for that time whether you needed to leave at that time or not.

Because of this, I switched to controlling scheduled charging with the charge port, so that came on at the start of the off-peak period and off at the end of it, which worked perfectly. Sadly this just doesn't work with the Model 3, as it's non-compliant with both the IEC61851 charging standard and with the owner's manual (the latter states the car will resume a charge after a power outage - it doesn't).

I've found that the easiest way to schedule charging is to use the functionality in the car to set a charge start time, and then hope that it is fully charged (to the set limit) before the end of the off-peak tariff period. This can be a struggle at times. I drove a couple of hundred miles or so in a day earlier this week, and the car didn't stop charging until about an hour after the end of the off-peak period the following day, so the last hour of charging cost nearly twice as much as it should have.
 
I do the same as @Jeremy Harris in that I set the scheduled charging in the car for the start of my off-peak period with Octopus (currently 20.30 on the GO Faster trial) but I use the app to set the charge limit to stay within the off-peak period, working on adding 10% charge an hour.

This means I can add up to 50% in the five hour window.

The only time I go over into the peak period is if I am going on a long journey and need the extra range. In the five months I’ve had the car I think that’s happened twice so far.

I've had the Ohme wall charger since getting the Model 3 back in November and it has had no issues at all, mainly as the app logs in to your Tesla account to workaround Tesla charging implementation peculiarities.

The charger just works... links with some of the energy providers including Octopus and will charge based on the criteria you give it to get the best tariff but does give you the flexibility to use it as a dumb charger or ignore the tariff restrictions.

I'd definitely recommend it and can confirm it works very well with a Model 3.

For some reason I temporarily forgot that Tesla communications come from a dimension that operates within a completely different time algorithm. I don't know what I was thinking ... o_O

My concern with this is that you are giving a third party complete access to your Tesla account and credentials. In part this is because Tesla use the same credentials to access your account as are used to access and control the car, but I'm still not sure I like the idea of giving a third party this level of access, both in terms of controlling the car, and in terms of access to my Tesla account. How secure is the Ohme system? Is it impossible for anyone to hack into it and get your authorisation credentials?

Anything connected to internet has the potential.

Not really. Everything transmitted via HTTPS is encrypted, so relatively secure.

Giving your Tesla account log on details to a third party app provider is similar to giving them a key to your car and also allowing them full access to everything you do with it, including where you live, where you drive to, where you work and also giving them access to all the data/documents that are accessible to you via your Tesla account (invoices, payment card data, etc).

It may well be that Ohme are both trustworthy, and have very secure systems, such that your Tesla account log on details will be securely looked after by them. However, the track record of some other smart charge point suppliers isn't that good when it comes to security, and it is a fact that smaller manufacturers tend to invest less in secure systems.

This is possibly true, although the same can be said about Tesla and their systems as well... there is always a potential point of failure somewhere in the chain. I can only speak from experience.

Ohme do partner with Octopus Energy, if that's any indication of their seriousness, and for now, it's working well for me.
 
It all comes down to trust, really, doesn't it?

I have to trust Tesla, as even without my account credentials they can do what they like with my car and the data they derive from it. That's a condition of purchase, much like agreeing to the Ts and Cs of any data gathering organisation.

I had a pretty grim experience with Octopus, when they took over when Iresa went bust, and the thing that made me fall out with them was their complete and utter incompetence in getting my bill right, and the length of time they took to do this, which prevented me moving to a supplier that actually managed to get simple data and account management right. Would I trust Octopus with my Tesla account credentials? Absolutely not, I have zero confidence in them, based on 5 months of constant hassle with them.

There's no doubt that Tesla account data will be of significant value to hackers. It's a bit of a goldmine in terms of the data that can be acquired by using it, including when owners are away from home, where they live, where they park their car, etc, etc. I've no doubt that hackers are targeting Tesla's servers, but I have to trust that Tesla have put in place good security, as their reputation depends on it.

What about other companies that hold Tesla account data, though? They have to also be a target for hackers, and they may not have as much to lose if they suffer a data breach. Are companies like Ohme going to invest as much as Tesla in keeping data secure? I honestly don't know, but I know that I'd not trust them, yet, just because I'm not yet confident that they are trustworthy guardians of this data. By the same token I will not use TeslaFi, as the risks are exactly the same with that.

As you say, it comes down to trust. I may have been very fortunate, but Octopus has been, by far, the best energy company I've had, but everyone has different experiences.

For the moment, I'm ok to trust them and Ohme, and to the original topic of the thread, I'm very happy with the Ohme wall charger.

I Ordered M3 and was told delivery in Feb. So looking for a home charge solution. But after spend some time here, I feel that maybe don’t need one.

For example:

M3 SR+ do 10000 miles a year.
Run 240 miles / fully charge.
That’s about 42 full charge/year
42x60kw=2520kwh

Charge Only @15p/Kwh,cost £378
Charge Only @ 5pkwh, cost £126

There’s £252/per different. And we spend £400-£500 upfront to have a home charge.

There few free charge point around my house and some near where I work. I think a 3 pin may enough for me.
