After a consideration of the limitations of litigating before the Civil and Adminstrative Tribunal, I've decided to try going through NSW Fair Trading instead. What follows is a draft of my submission. I invite comments. If anyone wants to use all or part of this in their own complaint to a...

You may find that your firmware has been upgraded again. That causes a reboot, and rebooting makes the connection issue go away - for a while.

If it was a defect, it was one only in the sense that it allowed owners to do something that Tesla doesn't want them to do. Tesla are on very shaky ground when they modify the system to prevent that, since it cannot in any sense be described as an upgrade, and there's nothing that permits them...

It wasn't given for free. It was part of the originally supplied firmware, which was paid for as part of the system. Further, Telsa have committed trespass by using their access to the system to do things that do not fit the description of the changes they say they'll make in the warranty. It's...

I'm seriously looking at it, though there are some complications due to the fact that the Australian Consumer Law doesn't really consider the situation where a manufacturer makes changes after the sale, without the owner's consent. One may be able to make a case that such conduct is a "trespass...

Rather than add a field, the've changed the existing field name from "mode" to "real_mode",

The difficulty for them is that they're essentially saying that the manufacturer can decide, after sale, which features form part of the product, and are thereby affected by the Australian Consumer Law, and which features do not. An analogy would be that you find that the cigar lighter in your...

In some jurisdictions, it may be possile to make Tesla refund the entire cost of your system, and pay for its removal. Given that there are other systems out there, including ones that have the ability for user control.

Another point that occurs to me is that in the case of a wired ethernet connection, there is a UTP cable that's, in many cases, accessible from outside the house, just by undoing a screw. It woudn't be particularly difficult to add another WIFI router inside the gateway housing, where owners...

I was clearly tempting fate. My web server has frozen again.

I doubt discussing the api issue with them will achieve anything other than pushing your blood pressure up. It think it remains the case that the lack of web access is a bug. If they can't otherwise address the failure to update the backup reserve, then with luck you can persuade them to try...

I'm doing this through the web interface, not through the ap. Settings done through the web interface used to take place immediately. Indeed, they still do - if they're going to take place at all.

I've done some experiments that suggest to me that not every attempt to set the reserve level is honoured. It says it's changed it, but it looks as if it's maintining an internal reserve level which only gets altered if the last change wasn't too recent. This is consistent with my earlier...

One could hope that such things are better protected. Indeed, if updates are signed, there needn't be anything potentially vulnerable on the update server. The worst a hacker could do would be to prevent updates from taking place.

Telsa support seem to have considerable remote access to the internals of powerwall gateways. Most people will likely have the gateway on their internal lan. If it's a wired lan, then the gateway has the potential to see all the traffic on the lan. If Tesla support got hacked, this would...

The system will include current transfomers clamped on to the conductors coming from the grid. Given that the system knows the voltage, it can use the current transformers to calculate the power.

Although I've got access back, there's still strange stuff going on. At the moment, my powerwall is draining, even though it's below the reserve threshold, and there's no grid outage. Tomorrow, I'll be suggesting to Tesla Australia that it's time to downgrade me to the working firmware until...

I doubt that 1.21.0 will resolve this because as far as I know, Tesla have not yet figured out what's wrong. It can be difficult to determine whether one's managed to reset the gateway. Might be worth calling up support and asking them to reboot it remotely. They may be willing.

All the evidence now is that this a bug, not a deliberate action on the part of Tesla. You should get the connection back if you reset your gateway, either by pressing the reset button, if it has one, or by turning the powerwall off, and powering everything down, including solar, for ten minutes...

Yes, 60 kilobytes per minute, or 1 kilobyte per second. About 2.5 gigabytes per month.

I'm aghast at how much data is sent from the Powerwall gateway to a server on the internet. Granted it needs to provide the data that the ap needs, but it's running at about 60kB per minute. That's way more than could conceivably be required for the ap, and suggests Tesla are engaged in...

I would expect that to be a non-compliant installation. It should not be possible to reach any live parts without using tools.

Since the reboot initiated by Tesal reenabled my access to the gateway webserver, it's become apparent that the webserver often fails, and is restarted. The effect is for it to cease accepting the bearer token, necessitating a new login. Restarting seems to take about a minute, and during that...

I've noticed that it makes https connections to the same servers. The http connections identify themselves as Go-http-client/1.1. More than one megabyte in a couple of days.

At a guess, they've introduced a new field, which is probably called "real_mode". You could try including that and setting it to "self_consumption".

Have you been following the related thread "Lost connectivity on wired ethernet to powerwalls" ? It really seems now that this is a bug/fault, and not something that Tesla intended. Sylvia.

And no LEDs that might be visible through the hole either. Seem like it's a quite different model.

I've been looking at the traffic between the powerwall 2 gateway and the internet. Most of it is encrypted, and since I have no access to the certificate store on the gateway, the usual man-in-the-middle attack can't be implemented. However, some traffic is in plain text. One of the oddest...

There's no arguing with that. I wonder whether the button is absent, or just the hole. Mine was intalled in May.

Even when I had no access to the web server, I could still ping it. Indeed, examining network traffic showed that the gateway was responding to connection requests to both ports 80 and 443, was accepting them, and was acknowleging data sent to them - it just wasn't sending any response data...

Perhaps I should have mentioned that on my gateway box, there's a clip on the bottom right corner. Pulling it outwards lets the front panel drop down a couple of centimetres, and then it opens like a door. There's nothing dangerous inside. That's were the hole marked Reset is to be found. To...

Tesla Australia have restored my access to the webserver by rebooting the gateway remotely. I confirmed with the tech guy that the gateway can also be rebooted by pressing the reset button, visible through the hole marked Reset on front panel, though it seems that not all gateways have that...

I wanted to check that Tesla Motors Australia Pty Ltd is the importer of the Powerwall, for the purpose of starting proceeedings, so I visited their office in St Leonards, NSW, today. I met the managing director, Mark Twidwell, who confirmed that they are indeed the importer. But he also invited...

I can't find anywhere where Telsla say, or even imply, that they are permitted to control your system remotely. The terms of the warranty allow them to upgrade you system, but issuing a command that disables the web server is not upgrading. I don't know about US law, but Australian law contains...

I have already written software to run my system that downloads a weather forecast, and uses that for an initial estimate of the solar energy available the next day. Based on that it decides whether to charge from the grid during the off peak early hours of the morming. During the day it takes...

I was able to access the new UI via my wired ethernet for one day after my gateway's firmware was upgraded. Then it stopped working. So I tried the TEGxxx WiFi, but got the same result. The connection request to the gateway is accepted, but it doesn't respond to anything sent to it. I'm...

The value you're using as the password appears to be the serial number, so it shoud be unique, as should the MAC address. However, nothing you retrieve from the gateway could possibly consitute proof, in a formal sense, that the associated data also came from the gateway because anything you...

Apologies to cwied, I managed to mess up the quoting in my reply. From "I've tried a man-in-the-middle..." is my response.

I've also noticed that the powerall stops for a short period when the reserve percentage is set, so one wants to avoid doing that during a blackout.There remains the relatively remote possibility that a blackout starts just as one does this, and the question of whether the system that's making...

Perhaps worth noting that in Australia, not all retailers apply the weekend TOU rates for public holidays, and not all retailers apply daylight saving time to the times the TOU use rates apply even in states that have daylight saving.

When you have solar as well as a powerwall, the powerwall is trying to supply or consume just the difference between the solar output and the load. To do that it has to measure both, and it doesn't react instantaneously. What I've seen is that when there's an appliance that repeatedly and...
