I know it very well, i'm an IT Enterprise Architect and i do design / program / build IoT and similar devices both for fun and job, first thing i said if you read the comment it's that, there are connections to 5G, on a grade of which few can even imagine, it goes way over mind control and it's something fucking scary indeed, but still, nothing to do with spreading bullshit like this, we don't need more alarmism now, plus, actually the devices / towers are already in place, and few know bout, there are different type of 5G antennas, standard 'data' ones, and ones that use in parallel also ultrasounds, can scan any direction, and that has to do with pin pointing devices, positions, etc, even if your device is off

And then, there's the (in)famous Lora network that's the backbone of embedded IoT devices communications, no 4/5/6G or anything similar, but a decentralized mash network where everything talk, and a single transmitter can reach the nanometer or smaller, with almost no active power usage while working

Think about a coincell battery that fill itself and work for years

Much worse than what the average expects
