Yes, Model Y on whatever was right before 2023.44.30.7 (it updated after our trip I think). It was wack, same as you are explaining and made it really hard to know without fiddling (stop nav, re-do nav, etc).

Same issue here on 2023.32.6, no change to my schedule for a long time and location is correct. Disabled for now -- it was just me trying to micro optimize battery level to be as low as possible for the day. No TOU rates.

Okay, so Stellantis will announce soon given the little hints they dropped. Hyundai probably worried about charge rates/curves on their 800V architecture, but willing I'm sure. The big question is when the Germans will get on the train now.

@davewill nothing I can think of, not even sunrise where automations adjust outdoor lights. I have the car for one more day, if it happens between 5-5:10am EST I'm going to freak out... ... and then I'm going to return the car to the SA and get my MY back and cross fingers :)

I've been using a HPWC on a 14-50, derated to 40A, as a temporary solution until I hardwire in a few units. Yes, technically this is not 1) to code and 2) can cause issues as the HPWC has ground fault protection built-in. That said, it's been working for hundreds of charge cycles on our MY. It...

For those that are able to get the the nominal and buffer, perhaps allowing those users to type in the values for now until there is a way via the API could work as a stop gap measure. I finally got Scan My Tesla installed on my 2023 MYLR and it is showing 78.7kWh for the nominal full pack...

100% agree -- stick with the Tesla Mobile Connector, which includes a 5-15 and 14-50, and you can add additional dongles as needed. It's just a hair over $200. You can do up to 32A that way. Lectron stuff is cheap Chinese stuff, not UL listed, etc. It'll probably work fine... until it doesn't...

So when Tessie set my Model Y to 78.5 by default, is that detecting the 82.1 and setting a start point? TBH, I've been trying to follow but still have no idea how I can get my current rough degradation in Tessie :) At around 3200 miles (car purchased in Feb 2023), I'm seeing 0% default and 4.1%...

@AAKEE Is this an Excel/Google Sheet you can share as a template?

@AAKEE you sure that's what should be done for Tessie? On a new car will immediately show something like 4-5% degradation and way below the fleet average.

I've almost pulled the trigger on some eBay or local specials, but not worth losing the warranty IMHO. Thanks for the heads up.

True. 120V last resort, since I think it's around what 70% efficient? But yeah any 240V with sufficient amperage is going to be in the 90%+ range. Then again, any charge is better than no charge!

Components are not running for a longer duration sucking down 100W+ thus saving energy. You aren't even approaching any level of stress on the battery being below 1C at 48A. Only DC fast charging even approaches stress levels. Charge up at 48A to 80% or your poison and enjoy!

Why limit to 24? You should charge as fast as possible on AC charging for efficiency. Also if a unit is plugged into a car but not actively charging it still reserves 6A I believe from the network limit.

I've been creating automations to keep the car preconditioned at specific places (e.g., grocery store, kids school, etc) after parking. It's resulting in a lot of automations. Does anyone think it'd be useful to have more than location in the automation interface? So Any or 1..n locations...

Is this out? I don't see it on the published nor TestFlight versions.

I'm using the standard SAK-60 modules to shed on generator only, I don't have the SAK-60MS. That said the SAK-60 has performed great for me and these units are very similar. PSP did just recently raise prices, but I recommend calling Michael there and they may even be able to do a discount...

I measured 2.82 kWh of energy usage on my Emporia this morning while preconditioning a car in 28F weather. If the weather had been warmer, the energy usage would have been significantly lower. Unless this is something regular, I don't think it's worth it to adjust the schedule and risk...

"Promotion has ended" Darn, will be watching for another deal.

Highly recommend, and especially if you have such an investment in an EV, a Type 1 or Type 2 SPD. I have a Type 1 at my ATS switch as I'm worried that it'll come in via service or generator.

IIRC, the BMC can't do cell leveling without going to 90%+. Many people just say charge to 90% and it seems to have no negative impact to battery health. That's what I'm doing.

That 90C 6 AWG is very confusing. They should either not state the preferred wire size and delegate to code, or give valid examples including all the nuances of NM-B, THHN in conduit, etc. That's a slippery slope though, so they should just cite "follow code."

Sorry. Installing without separate breakers. Today you must install the Gen3 with separate breakers per the installation manual.

I think we all agree that it is not in code today due to §110.3(B). On the confusion topic, let's just say that I'm not the only one confused why Tesla has this restriction today. So is their in-house installer network staff and their own installer network. I guess it's good to have company.

Sorry, I'm just saying that the Tesla PDF manual (not website) seems to just be written without the option that would pass code if written today. Right, it is an option. Having the option should allow for installations with the larger same sized wiring without breakers objectively when looking...

Prior to NEC 2023 perhaps, but I don't understand why that would matter with the latest code. The Energy Management System (EMS) can control the loads and allows the service, feeder and branch circuits to be oversubscribed. Tesla Power Sharing fits the definition of an EMS, including...

Indeed that is weird. I still want one though :) As long as you have a good 14-50 outlet it should be safe. My guess is all the cheap $10 home improvement 14-50s is the reason they capped it to 32A on the latest generation.

Oh it's totally capable of that and way more. But that option you had is much much cheaper and should be fine, just a little more DIY.

Nice! What type of circuit do you have? If similar to my upcoming situation, you could squeeze out a little more. For example, I was going to set my network to 52A (which is 80% of 65A calculated for 6/2 MC @ 75C) for the network for example. Not sure what happens if two cars are connected and...

I actually just ordered another SAK-60 today for my new circuit, and it was $149 before tax/shipping. Not too bad: Universal 60 AMP Wireless Generator Load Drop & Load Manage Relay

I use the SAK-60 from PSP to load shed my 60A circuits so that they don't run on the generator. Standard load shed modules from Kohler (what I have) or Generac only handly 50A. Anyway, I was placing a new order and noticed they have a new product called the SAK-60MS. It's very similar to the...

Another aside is using power sharing with just one unit lets you squeeze out 4A more because you can set the unit to 48A but the network to 44A to match code for 6 NB-B. Neat. UPDATE: You can't do this with one unit, I just tried. Power Sharing requires another unit to set up, so I have no...

So one interesting scenario with 6/2 MC. 80% of the rated 65A @ 75C for the 6/2 MC results in 52A. Can I set the network limit to 52A, and the units left at 48A? Not sure if it helps though with two cars connected. The minimum is 6A for each car connected to a HPWC, leaving 46A for the other...

Hopefully someone is willing to document a re-commission of their units or new setup so we can have a little more clarity. I'll make sure to do it once I get another WC

That is interesting. I read that you can set each unit, e.g. a slave unit matching the breaker it is on. Example: Network: 48A Master: 48A Slave: 40A Slave: 48A In that case you'd have to set the slave units individually to match the breaker in the sub-panel. Not going to matter for me since...

Hmm, so either any integer or the same options. Which one is it? :)

How does it work when a car is fully charged? It still requires the 6A or whatever per connected EV right? Any limits on the network load limit? Can you enter 44A and will it negotiate 44A to a single car for example (for NB-B that can't do full 48A).

Agreed, alongside my interpretation of the spirit and letter of the code as well.

Ah, so you decided to use a Polaris instead of subpanel for a Gen 3? Technically not allowed per the install manual, but obviously works completely fine and within NEC 2023 code.

It's not that the Gen 3 isn't capable of it (in that electrically, physically, etc), it's that they wrote the docs matching the NEC 2020 code. Sadly NEC §110.3(B) makes that a part of being in code. NEC 2023 allows for this in §625.40 and I'm trying to get Tesla to match their documentation. I...

You rock! I mentioned on the other thread that anyone interested in this should see if Telsa can provide guidance on installation on the same branch with the new clarified NEC 2023 rules, as it goes against their manual which hits 111.3(B) saying which says "Listed or labeled equipment shall be...

Your research on this and the other thread citing the parts of the NEC code was great. I've been wondering the same thing on my side though, and the darn NEC catch all of 110.3(B) saying "Listed or labeled equipment shall be installed and used in accordance with any instructions included in the...
