You don't need to charge LFP batteries to 100%, but you can, without the same deleterious effect that has on other LiOn batteries. As to why Tesla recommends that you regularly charge LFP batteries to 100%, see here. TL;DR: it helps with keeping the Battery Management System calibrated.

Mmmm. IIUC, the phone has to be far enough away from the car that it's not connected via bluetooth to the car. That means two attackers ... 20 meters is really far for a bluetooth connection. 10m is more typical range. Your point is well-taken, though: "near" need not be all that near.

The attack is targetted: it requires one attacker near the victim's phone and one attacker near the victim's car. (And they need to communicate over wifi or cellular data.) That's not a scenario I'm super-worried about (if the attackers are that dedicated, they can probably find other, easier...

Damn! Was planning on charging there in a couple of weeks. Fingers still crossed ...

At least when I got my car, I got two 30-day permits. And I needed both of them. It took a month for the paperwork to arrive from Tesla and then another couple of week for an appointment at the Tax Assessor/Collector's office.

Dunno about the battery pack, but the cabin temperature would easily exceed that in Texas in the summer. OTOH, I have a hard time imagining a circumstance in which the battery pack temperature greatly exceeds the cabin temperature. So, if you have cabin overheat protection turned on, I think...

From the photo in #11, it looks like there will be a lot more than 3.

Of course, your Tesla has its own API, that is well-worth digging into. In particular, it will tell you the kWh added in the last charge cycle (which is easier than querying the Wall Charger before and after and subtracting).

Whether the API is accessible only on your LAN or over the internet is entirely up to your home Router. ATM, there is no publicly-available app that displays the data from the API. But lots of us have slapped-together something rough-'n-ready to display the data we are interested in.

To configure the Wall connector, I believe you need to connect to its Hotspot, using the password on the QuickStart pamphlet you received (see here for instructions); you can't do that via your wifi network. But, for getting data off of the Wall connected, the above API endpoints work well...

Yes.

I manually upgraded to 21.18. But that's it: "No updates available" when I try checking for updates in the interface. Where can one get 21.29? The link from Troubleshooting a Gen 3 Wall Connector points to 21.18.

I had to do a manual upgrade. Download the latest firmware from this page. Connect to http://192.168.92.1/service on the HPWC's hotspot, and install the firmware manually.

I was getting 120V/12A with the supplied 5-15 plug adapter. At ~70% efficiency, that translated to 4-5 mi/hr. With the Tesla Wall Charger, operating at 240V/48A, I get 45 mi/hr.

You absolutely do want 2 (30 day) temporary tags in TX. My paperwork took a month to arrive. Then scheduling an appointment at the Tax Collector/Assessor was another 2 weeks.
