I think it was introduced with at least the S9+, mine has had DeX since I got it originally.

I looked through the material, but I'm still at a loss how this is different than any recent battery/inverter combination like Ecoflow/Jackery/etc or a UPS with an app. I'm an electrician, and very in to new electrical products but this one just makes me wonder how it's different.

I absolutely love how once things get down to 1 AWG they realized they had a problem and just started adding zeros. Then that got a bit silly, so when they reached 4/0 AWG they switched to KCMIL measurements and the numbers start going up.

Cody's Lab did a video with some experiments collecting and refining road dust. As I recall, he did manage to obtain a small bead of platinum-group metals but it didn't appear to be economically viable at least at a small scale.

Does this not take in to account lyrics in musical movies? I looked up Across the Universe and it reported zero name drops despite there being at least a dozen.

I haven't tried the ESP32-H2 or ESP32-C6 yet, but they have 802.15.4 radios so they can be used with Zigbee or Threads (plus WiFi 6 on the C6). I definitely am eager to play around with one, most of my current projects have been on the ESP32-C3.

I do a lot with solar for work, and had a few questions immediately. Are the Renology panels what you had access to chosen for a specific purpose? Some of the panels we use for high efficiency jobs are 400+ watts at a size closer to your 200w panels than your 440w panels. Also, have you considered using any type of optimizer or per-panel MPPT? Those can have a significant impact on real-world performance in my experience, especially in cases of shading or uneven panel soiling. With high efficiency panels, panel optimizers, and series stringing you could likely get to DC charging voltages (although at paltry amperage).

I also built something along these lines about three years ago and use it every year. I started off with a stainless steel hall effect float switch and it's lasted so far, on its fourth year. I don't have a pump for my water, I use my RO system as a source and a solenoid as a valve. I do use a peristaltic pump to meter out Christmas tree preservative according to the readings from a flow meter on the water side though. It's worked wonderfully, even when changing tree stands.

IGBT's changed power conversion as we know it!

Depends on the type of device you're talking about. The company I work for installs batteries and solar on homes as part of its business and we were surprised to find cell modems starting to come installed inside the battery system we use most often - with no notice to us or apparent change in how the system operates. It's not for customer-accessible statistics/usage information, those still require a hardwired connection. We haven't been able to get a good answer from the company about why they started being installed.

I've heard it said both ways on the news today, but I'm leaning towards R-Evil.

In Sonoma County Comcast Business is down. T-Mobile also seems to be having issues.

By the way, take a look at the PurpleAir map - you can get an idea of the size and spread of the outage by the number of offline air quality sensors. Works for power outages too!

When you select not interested, it gives the option of saying it's either because you already watched the video or that you don't like the channel. I don't know quite why they keep recommending videos I've watched recently, but at least telling YouTube I've seen a video (...) prevents it from spamming my recommendations.
