What does the CAC report? I have OVMS to look it up and I get 163.6 CAC, it’s definitely not got the range it used to have after the 3.0 swap, but it’s still charging and driving ok. Mine was one of the earliest 3.0 upgrades. I keep it in storage mode most of the time, at 50-75% SOC.

New funding for Span who seem to be working on the general problem of integrating panels and batteries etc. Span raises $90M to make smart panels the gateway to home…

Thanks for the advice, and sharing your expertise. The eGauges (installed last Nov on both sides of the house) show how much backfeed comes from the panel that has solar, pool pumps etc. on it, and it's less than 20KW in practice, but if we had everything in the house turned off in the...

Thanks for the advice. I've talked to the vendor who installed my solar, who aren't Tesla distributors but do install batteries, and who put in eGauges so I can see the actual power flows. I've also talked to the local Tesla PW distributor who is going to visit this week. After waiting for over...

I'm surprised no-one else seems to have figured it out already... I think we're going to have 4 PW on the solar side, and 2 PW on the bedroom side. We get fairly frequent multi-hour outages, but if we get a multi-day outage, we can move to the guest house. Also, if in the future a 400A Tesla...

The Eaton circuit breakers look plausible, they have up to 50A, with a documented developer portal. Smart breakers Has anyone tried Eaton or something similar to shut off individual circuits during an outage?

Yes, over half the house load is on that panel, kitchen (all electric), pool pumps, living area, guest house, three of the four heat pumps.

The heat pumps cycle on and off to avoid freezing up when it gets cold, and are working hard to heat a large space with high ceilings and solid concrete slumpstone block walls (excellent for fire resistance, but not good for keeping warm). I got the biggest option I could find, and we've also...

That's very useful info, if I understand that correctly, I can use the contactor to trigger my home automation, and interface from there to reduce load and shut down circuits.

The Shelly.cloud switches look interesting, but I think I need connected circuit breakers that I can pop into the existing sub panels for a few key circuits. I have a home automation system that I can program to manage this, if I can figure out how to hook it up. I have Monterey Bay coastal...

OK, so the problem is that the solar is all on the other side of the property, on a 200A sub panel, and there's no easy way to run conduit to that side (no attic or subfloor and it's a long way). The main bedroom that I want to heat is on the side that doesn't have solar... thanks for clarifying...

We're at 600ft in the hills near Salinas, get plenty of sun, and I upgraded from 20KW to 30KW last year. Been there and done that and not doing it again. I have new heat pumps, and when its freezing outside they need help as my house is hard to heat. I have 4.5ton Mitsubishi and they have...

Thanks, that helps, so we'll have a gateway on each side, and probably 3 PW on each. How does that work for power sharing during an outage? Does each gateway connected bank of PW drain separately? I will only have solar on one side, so they need to be linked to recharge while off grid.

I have looked at other suppliers, they either can't stack enough batteries together to build a large installation, or the batteries themselves are physically bigger and need to be racked indoors. I need to have them outside to be near the main feed, and I need 6 powerwalls to give me enough...

I've got a "sprawling" single story house with a 400A feed and multiple sub-panels scattered around. We converted it to heat pumps for air and water a few years ago and have a large solar array connected to a 200A sub-panel on the far side of the house from the main feed. My main concern is that...

Still no response on email, but I did get through with a minimal wait on the phone to the generic number. The guy on the phone was helpful, apologized for the delay, said they got behind and are starting ramp up deliveries again. My install has slipped from design in June to design in a few...

I ordered power walls in February, had onsite visit in March, they said they would have a design in June, and not a peep out of them since March. Tried every week or so. I don't have a project advisor named on my account page. The last number I had from an advisor is no longer connected. I've...

I added Carbotech XP10 and new fluid to my M3P, worked it pretty hard at an AutoX and a track day, and now it’s squealing a lot on the street.tried a few things but it won’t go away. So since I’m going to take it apart again anyway I decided to upgrade the discs as well as put on new pads. I’m...

I have a Clipper Creek 70A Roadster specific charger, but moved house last year, and don't have anywhere to wire it in the new house. I have a Model 3 on a 50A socket hooked up, and have an adaptor so can top up my roadster on that if I need to more than trickle charge it. If anyone's looking...

Yes, that's me.

I wrote up this story about how I was a very small part of helping Tesla pick the Lotus Elise as a partner for building the Roadster. The day that I gave the founder of Tesla a ride in my Lotus Elise in return for a ride in his… I've also uploaded a slide deck pdf that I got at the time by...

Thanks! I'll take a look this weekend.

Ideas for enhancements are being collected here adrianco/rs-tesla-telemetry Here's the current list.

Thanks! I don’t have any autoX telemetry data, so if you could share a file with me I can change the app to manage them better. AutoX has the start and finish in different locations, so we need a way to mark them separately somehow. It would also be good to compare runs in the app, which would...

Creating this thread for discussion of the tool, announcements of updates to it, and sharing results at different tracks. For those of you who have Model 3 or Y Performance cars with track mode, the car saves telemetry files and videos. In my spare time over the last few months I've written an...

Here’s a video on how to install it and run it I n a Mac Takes a few minutes and nothing too tricky. Windows is similar.

For those of you who have telemetry files and want to view them, or if you manually process them to change the timestamps to be cumulative for import to other tools like RaceRender I've done a bunch more work on my open source telemetry viewer, with helpful guidance from @Electric Dream - you...

Another weekend's work. Zoomable plots added. I think I need some additional tracks to test with, would people be willing to share some telemetry files with me? Next step is to make it easy to install and use as a local application on Mac/PC.

Figured out how to calculate distance along the track by adding up the time intervals and the speed, and happily, got a result that matched the official length of Laguna Seca, so plots are easier to compare now. adrianco/rs-tesla-telemetry

I got a better image, and added some of the options discussed at the beginning of this thread.

I’m figuring out a way to save/share laps for each track for reference. To do that needs a lot of additional metadata. I’ve been making a way to capture the data that isn’t in the telemetry file. Would like input from people on what to add, also what are the popular custom wheel/tire/brake...

I've been working some more on my open source telemetry analyzer, made some good progress on another update adrianco/rs-tesla-telemetry For now, it needs to be run locally after downloading the free RStudio app and connecting that to GitHub, and loads a local file before it displays in the...

Distracted myself from current events by learning to write a browser based track file viewer (that currently runs locally so it can load the file). Shared it on GitHub, this time it should be easy to load into RStudio. Eventually this could be a standalone app where you upload your file, but so...

adrianco/r-tesla-telemetry I updated the summary to include acceleration and braking, and documented how to make basic plots like this one showing my out lap from the pits.

Very cool! Thanks for trying it out and getting it to work, I wasn't sure if I had enough info in the README to be helpful. There's some more data to add, and some plots to generate (it will save png files), when I get a bit more time.

I was using full throttle coming out of the corners and along the straights, was coasting a bit going into corners. This was late in the afternoon on a hot day in June, and I was being very cautious, as it was my first time taking the M3P on the track. My Lotus Elise engine had blown up that...

I decided to noodle around with the telemetry file and wrote some initial code in R that processes it into a summary and splits the data into laps. Posted it on GitHub in case anyone else finds it useful or wants to extend it. adrianco/r-tesla-telemetry Here's a summary of my first full...

I’ve been running Toyo R1R for a while. About to put the third set on the car. I run 205 wide on stock rims on the front, they sometimes rub on the mud flap mount area if I hit a bump in a corner, but I’ve never had any issues. Fronts last twice as long as rears as long as the alignment stays good.

Stock M3P

Thanks for that. I was pushing it fairly hard in some of the corners. Gave up on spreadsheet and used R to convert the bar to psi (*14.5) LF "1st Qu.:41.33 " "Max. :44.59 " RF "1st Qu.:41.33 " "Max. :46.04 " LR "1st Qu.:41.33 " "Max. :44.59 "RR "1st Qu.:40.96 " "Max. :43.86 "...

Thanks, that’s helpful.

Pressures are in bar rather than PSI. X axis is lap number. 2 was warm up lap, lap 3 and 4 were about 1m52s laps. Acceleration plot below. I’d be interested to hear what lateral acceleration other people get on stock setups.

I get the data from the CSV file. I think the tires were to hard to start with and it was a cold day, so they never really heated up much. I’ll plot the data and see what it looks like.

thanks I ordered a Samsung T7, and I’ll try dropping the pressure to 35 cold next time, and work up from there. The pressures were 41 cold and 43 hot on the track.

I ran Laguna Seca yesterday in my stock M3P. Fastest lap was 1:52. It was a fairly cool day and the car didn’t overheat too much. I also skipped a session and went to the Monterey supercharger (10miles away) for a 66KW top up. I’m not looking to change the car (I have a Lotus Elise as my usual...

They reconditioned the PEM, it failed again in less than a year, so they changed it again under warranty, and it's been fine since.

Had a drive today with 2020.12 and I think it’s an improvement. Navigate on Autopilot did a good job of some freeway intersections. Then it started to rain and it shut off Navigate.

I just got a 2020.12 update notification for my M3P

My guess is that the software team is working on Model Y support and a bigger FSD update and that’s why there is less incremental update activity.

Picked up our car this morning. Blue/white M3P. The little carbon fiber spoiler doesn’t fit perfectly and one end hadn’t glued down, pushed it hard and it seemed to take, otherwise nothing to complain about. We ordered 12/9.
