I know I'm late to this thread. The only smart meter system in this
area is a polling system. The meter reader just drives down the street
while his truck transmits a polling message, which the meters then reply
to. The meters only speak when spoken too, so we never really had a
problem with those. There's still a huge labor savings for the power
company, and apparently it was a lot cheaper than deploying the mesh
system from the same manufacturer.
What I infer from these threads is the effect of this smart meter stuff
is heavily dependent on what equipment the power company bought, how
it's deployed, and how it's configured. So yeah, YMMV is the only real
answer.

Interesting. The majority of our 900 subs are located in prime smart
meter territory. I've worked with several of the power companies
across western Kansas and they all run a version of Landis Gyr meters
with is FHSS 900 ISM (see pic here

They transmit infrequently in short bursts...very little data. The
only time we see interference is when they mass update software. After
some discussion, we convinced them to run updates during our non-peak
times. So far we've been able to co-exist peacefully. YMMV.

Everywhere.
Smartgrid is probably the main culprit.
And without LOS, all signals get scattered by the same foliage and other
obstacles that are scattering the signal you are trying to pick up. So
literally, the interference sources are everywhere. Sometimes I blame the
midichlorians.

We swapped out an FSK AP in a high interference area today. No magic,
works about the same.
Too bad, even the installer liked the SM and antenna. Even the coax boots
are nice.
Will probably work well for those of you who don't have -65 noise floors.
We are going to have to give up on 900 MHz at this location. This was the
last gasp.
