If it's inside BMS, it's probably just Lora style transmitters giving off data so that you can read if the batteries are low.

It's not exactly brain surgery to hunt down the microcontroller and dump it if there is something crazy going on.

We're becoming so inept it might even just be a fucking bluetooth radio which would be a pretty common thing to see on a BMS.

We have officially hit the point where radio waves are the devil. As a lora nerd and a ham operator, it's funny that the public is starting to catch on to all this.

It's like the microchips in the COVID vaccine thing. Why would bill gates and the ghost of Steve jobs try to sneak all this into your life when they already got paid 800 bucks for you to own a smartphone?!? You already did it!

This is just a part of normal infrastructure now and your Amazon echo is way more useful to them than whatever conspiracy theory is getting cooked up about this shit.

Hell most of it is horribly implemented and borderline useless even if you had the explicit intent to be evil with it. Ffs

Hello fellow Ham.

Yeah, it's a radio in a battery management circuit. On the signpost, on the side of the road. What exactly is it spying on? Are they concerned that the signpost on the side of the road has too much knowledge?

Do they now know how much sunlight Central philly gets? Or how long before the battery in their crosswalk indicator, doesn't work anymore.

Back when the transceivers on Super Microboards were sending actual data home over the internet, that was relatively interesting news.

Come to think of it, I do kind of wish they were running meastastic for meshcore. That would be a great way to extend the networks. Transit-Authority providing off-grid comms for 20 bucks a node...

They keep refering to them as "undocumented cellular radios", which either means they have no idea what they're talking about (very probable) or that they're concerned it's getting on the Internet. In theory, decades from now they could maybe all turn off simultaneously and cause a noticeable lack of power. I guess.

Mostly, it's very frustrating that the articles are all about what inverters and batteries are and that the US doesn't trust China, instead of what the things they say they found actually fucking are.

"undocumented cellular radios"

Oh, now you've done it. Now ICE goons are smashing highway infrastructure and throwing it into vans.
