Flutterby™! : Rogue communication devices?

There's a lot of scare and not a lot of meat in this, but Rogue communication devices found in Chinese solar power inverters. It looks like maybe this is some smearing to support the "Decoupling from Foreign Adversarial Battery Dependence Act", being pushed by Rep. August Pfluger (R-TX).

I'm also interested at the notion that we have machines connecting to the cell phone data network that nobody can account for.
