Sense forgot my EV (Tesla)

technicalsupport

#1

One of the key reasons I bought my Sense was to track my Electric Vehicle usage.

After about 10 weeks, Hooray, Sense found my Tesla Model S (which I learned here is a device Sense claims to know all about). I charge my Tesla very nearly every night at midnight.

But Today, Sense failed to recognize my Tesla charging at midnight, despite seeing its vivid signature on the “Now” timeline.

For some reason (beyond me), Sense went back to learning my EV (as reported - My Home: Device Detection screen).

Anyone else experience this? Ben@Sense, any ideas??

Hey Ed,

Sorry to hear that Sense missed a charge there. Has Sense since picked up other charges? Our Tesla Model S detection algorithm still has some room for improvement (and might occasionally miss a charge), but it should detect most of your charges. Totally understand the frustration with this given the high wattage of the device, and it is something we’re working on.

With regards to it being reported in that learning section, that section is in need of some improvements itself for clarity and accuracy. In the case of your Model S, it likely appeared there because Sense is refining the device model. This refinement is a normal part of the detection process as Sense sees more instances of the device running in your home.

Good News Ben,

My Sense only missed one instance Telsa charging, Saturday a.m. starting at 12:00 a.m. and lasting into the 7:00 a.m. hour.

When I realized Sense had missed this detection, I decided (in the Sat. 11:00 a.m. hour) to add some more charge to the Tesla.

Sense picked up this charge. And then it again recognized my next scheduled charge on Sunday a.m. at midnight.

So it appears to be detecting the Tesla properly again.

BTW, I tried to delete my Blog entry on Sunday, but couldn’t do it. I will update it with this info instead.

Thanks for your quick, thoughtful and descriptive response.

Ed

Glad to hear it!

Ben, I have a Tesla S as well using their Wall Charger @ 48A. Its at a winter vacation house so we don’t charge there ever day (obviously). Its also on a TOU plan so charging starts after 8:00pm for us. Any way to “kickstart” the discovery process? Thanks

@svollum, unfortunately there isn’t much you can do to kickstart it. It really just comes down to Sense seeing it charging there a number of times, until it is confident that it has detected the signature of a Model S. You won’t need to charge it there daily, but it will likely take a couple dozen charges for it to be detected.

Hi Ben, Sense has again forgotten my Tesla Model S. I originally posted(11 days ago) that it missed a couple of charges, but then re-started to recognize charging which lasted for a couple days. All was well for a while.

Now it has again stopped recognizing charging… the last 5 or so charges. Sense went back to learning my EV (as reported - My Home: Device Detection screen)

Hi @Ed_Texas - very sorry you’re encountering this issue.

We’ve logged a bug with the data science team to try and root this out. Their initial thought when I sent it over was that this could be a complex issue that will take some time to figure out, so we may not have an immediate solution for you, but please let us know if the status changes.

Sorry again for the frustrations here. Thanks for your patience!

Sense has again forgotten my Tesla Model S twice now. I originally posted(38 days ago, then again 27 days ago) that it missed a couple of charges, but then it re-started to recognize charging which lasted for a couple days. All was well for a while.

Then it again stopped recognizing charging… the last 5 or so charges. Sense went back to learning my EV (as reported - My Home: Device Detection screen).

After supposedly learning my EV again, despite registering the EV Device as an official device, it failed to recognize all “charge” cycles. After about a week of of not recognizing any charges, I decided to manually delete the device.

That was nearly a month ago - No EV device!

Incidently, my SENSE hasn’t recognized ANY NEW DEVICES in this past month… hmmmm…
I there something else malfunctioning?

Ed,
If it’s any consolation, our Model S charging detection (80A) via Sense has disappeared a few times, but eventually come back. It’s been working for us reliably for about 6 months. My only regret is that they still can’t detect my 72A Model X charge cycle that consumes another 20% of the total usage hidden in “Other”.

Hi @Ed_Texas - very sorry this has been so frustrating for you. The team does have a bug about this specific issue and is working on it. Unfortunately, it’s fairly complex so they’re still working through it. We’ll be sure to update this thread when we know more!

Sorry again for the disappointment here, and thank you for your patience as we get it figured out. With this broader issue under control, we’ll be able to do a better job with detection across EVs, and hopefully start addressing vehicles like @kevin1’s Model X that still haven’t been detected.

Best,
Brad

Thanks…this is not the first time I’ve seen this behavior, and at one point (perhaps 6 months ago), I believe it was said to be a bug and to delete “discovered devices with zero data”. I’ve kept the three recent ones in case someone wants to take a look.

One of the three recent examples…the others were icemaker and light
