Curious whether anyone has specific details on whether or how a smart meter could possibly start a fire, as suggested by some other posts here.

From what I’ve researched, they contain multiple transceivers, which enable creating a mesh network with other meters in the same area, and can convey IoT (internet of things) traffic, allowing them to inter communicate with gas and water meter, and potentially any IoT appliance in a house or nearby.
Also appears they have some capability to talk ethernet over power lines.

In terms of causing a fire though, I can only speculate, and the few possibilities I can think of might be:

  1. Messing with mains voltage (doesn’t seem too likely)l, without having telltale components, like a heavy duty transformer).
  2. Messing with mains phasing or frequency. Again, would seem to require some oddball circuitry, could be hard to provide a reason for, seems unlikely to me.
  3. Interacting with smart batteries via wifi or other signals.

If I had to rank these in order of likelihood, I’d probably go 3,2,1. But again, only speculating. And encouraging further thoughts, research, and input.
