Device Detection Major Update: Tesla Model 3 - 1/9/19

Models roll out to different people at different times, so it might be a few days to a week before you see the benefits of the new models.

Question for the M3 owners here:

Have you been updated to the latest Tesla software update (build 2019.5.4)? We could use your help. Based on the data we’re seeing from current Tesla M3s in the field, something changed in Tesla signatures recently. We’re thinking it might be related to this firmware update, but need to dig a bit deeper.

If you’re on this firmware, could you let us know and give us permission to dig into your Tesla data? A simple “Yes, I’m on 2019.5.4 and you have permission to look at my data” will suffice.

Ryan if it helps I have a Tesla Model 3 on 2019.5.4 and a Model S on 2018.50.6, Neither has been detected yet, after many months. You have my permission to look at any of my data you want.


Yes, I’m on 2019.5.4 and you have my permission to look at my data.

Another thought I had on the loss of identification of the M3 is the weather. It’s been so cold, there is a restriction based on Temp of the battery pack via the BMS. If I’m right, you should be able to see a difference if you add GEO into your model for the last few weeks. I’m betting Florida doesn’t have the same problem.

@RyanAtSense - I am now on 2019.5.15 from 2018.50.6. My M3 has not been detected yet but you may see a clear difference between Friday evening’s charge and Monday evening’s charge.


I noticed that once I went from 2018.50.6 to 2019.5.15 on Tue evening Mar 12 2019, all Tesla Model 3 Long Range charging detection seems to have vanished. I was never offered 2019.5.4.

I also noticed that my Model 3 now charges for 2 minutes every 55 minutes for no apparent reason (other than new software), going from 90% to 90%, for about 3 minutes. But one charge was legit, pictured (screenshot taken before token issue fixed). the only workaround for now is to move the full charge limit slider from 90% to 80% after charging is complete, to keep it from cycling needlessly like this, 24x7.

Happy to help, here’s my permission:

Noted. I sent along your info to the DS team.

Great, thank you!

I’ve had sense meter for over 14 months and had model 3 for about 9 months now,I am using 48amp wall connector to charge, but nightly I only (top off) charge about 70 miles. If I wait a few days and perform a larger capacity charge, will this help detection. I am running 2019.x firmware. Knowing what part of my other is actually my a Tesla is still my greatest need from my sense meter.

First, welcome to the community!

Larger charges definitely help, rather than short top offs. But do keep in mind this known issue: INVESTIGATING: Tesla Model 3 detection accuracy issues

Ryan - I have Version 2019.5.15 f5def7e

Do you mind if I give your info over to the Support team so they can look at your data? We’re trying to compile as many houses as possible that are experiencing issues with Tesla detections, post-fw update.

yes please do.

Ryan - I dont mind. I dont like seeing the Always On and the Other bubble as the biggest in my dashboard.

Not sure if my situation is interesting for the dat science folks, but I had detection of a Tesla (I think Model 3, but maybe S), without any subsequent identifications, so I really don’t know which car it’s connected to.

I just got word that we’ll be starting the process of rolling out new models to M3s shortly. We have strong confidence that we’re modeling the new firmware with a high accuracy. As always, this doesn’t mean 100% of M3s in the field will get detected, but this should help those who lost their M3 detections recently. We’ll continue to refine these models in the coming weeks.


Sounds good, looking forward to it, and thank you for keeping us updated on progress!

By the way, if anybody is still looking at my data/charges, ignore March 15 to March 18 2019, when a Model S P70 was temporarily in my garage instead of my Model 3.

Ryan, do you know when this will be pushed out? Should I delete the currently recognized device (M3)? Mine sense detected my M3 the night before I updated to to 2019.5.15 so there have only been a couple spurts of activity on the device. Usually when the M3 is cycling an early morning charge from overnight phantom drain.

There shouldn’t be a need to delete the current device.

Models roll out at different times for different homes, depending on many factors. You will likely receive the updated models within the next two weeks. But, likely even sooner than that.
