I set this up with Frigate (running on my Home Assistant box). The Frigate+ models at least can identify trash bins with a fully local model and expose the count of bins as an entity via the Home Assistant addon. Combine that with the waste_collection_schedule addon the article mentions and a quick automation later I have a notification to my phone on the evening before pickup days if I forget to take them out, and another the following day if I forget to bring them back in.

Fair point, I’ve been evaluating WiFi for my project as well and the ESP32-S3 certainly has better link rates and latency, though I’ve not determined if it can truly run uncompressed. UX-wise my project is pairing to a smartphone so I’m not eager to require that users bring a WiFi network with them (something neither Android or iOS handle particularly gracefully), but regardless it would be good to have the option.

I’m using BLE GATT messaging with an upgrade path to L2CAP CoC channels for clients that support it. Roughly the path is: audio input -> opus encode -> BLE transmit -> smartphone/desktop. The latency floor ends up being ~80ms due to jitter buffer sizing, etc.

I've been experimenting with more-or-less this on the existing ESP32-S3 (well, to a smartphone/PC rather than a 2nd ESP32).

Practical bandwidth limits are in the ~72kb/s range with Bluetooth and a custom wire protocol, and Opus voice-mode encoding can't run in realtime beyond complexity 3; music encoding can't run at all. Maybe there's a more compute-friendly audio codec I'm not aware of, but as far as I know these chips just aren't quite powerful enough for high-quality music encoding, unfortunately. I'm hoping the S31 might be a bit better fit here (decent CPU boost + better SIMD).

Latency is still a bit rough with BT overhead. There might be some new options with LE audio on the S31 but I haven't found a way to get below ~80ms with the existing ESP32-S3 stack.

tl;dr, high quality voice is doable today with okay latency, music probably less so, maybe the S31 will be better

For what it’s worth, the Pixel 7 series (and maybe 6) has compatibility issues with some wireless chargers. It’s actually quite quick if you find one that plays nice: I measure 12-15 watts, so not much slower than wired. Incompatible chargers pull 3 watts or less, disconnect frequently, and often don’t even offset the phone’s regular drain.

I had to try a few to find one that works properly in my car. I’ve had good luck with chargers from Anker and Peak Design, and bad luck with Apple, JSAUX, and Spigen branded chargers. Google’s own chargers presumably work fine as well.

(Also, a lot of Qi chargers are extremely picky about the USB-PD or QC specs of the power adapter you use. I highly recommend using a USB power/voltage monitor to make sure they negotiate PD or QC power at 9/12v rather than the base 5v/1a. Without that, you’ll be charging at an absolute maximum of 5 watts before Qi losses.)

Most dealers don't do this, though admittedly as another commenter mentioned, this isn't stopping the all the less scrupulous dealers.

I paid MSRP for a Mach E I ordered online with relatively little fanfare, albeit with a ~10 month wait and a model year bump (for which Ford gave me a discount off the slightly higher MSRP).

By far the simplest solution is to just crack a window. Even a modest amount of fresh air exchange is enough to offset most of the CO2 generated by the people inside.

I use a relatively small 10x11ft spare bedroom as my home office. If I close the door and window, it'll quickly climb above 1200ppm after 15-30 minutes (and set off an alarm on my sensor). It'll cross 1500ppm easily if left unchecked. HVAC helps but gets outpaced quickly if my apartment windows are all closed.

That said, keeping doors open, running HVAC normally, and cracking a small window open, even 1-2 inches and on the opposite side of my apartment, is enough to keep CO2 levels around 550ppm while sleeping and 700ppm (in occupied rooms) while awake.

I have one of the Anker batteries. It'll happily take in >1000W from an AC wall outlet to charge fully in ~1hr. It's 300W max DC input from solar (which is where that 3.6hr number comes from) or 100W max from a 12v car adapter.

Those other batteries you linked look like a potentially great deal for raw capacity, though there's something to be said for having a mostly portable package with thermal management and a bunch of different inputs and high-powered outputs.

It was mentioned later in that thread, but the Kona EV also lets you control the AC remotely via its mobile app without leaving the keys in the car. I don't know if it'll run indefinitely, though; my old Chevy Volt would turn off remotely started climate control after 15 minutes or so, and I haven't tried in the Kona yet.

That said, even if it is time-limited, 15 minutes is usually enough to cool down the car without leaving the AC on all day.
