We seem to have gone a bit off topic. The modules are there to allow councils to control lights and get away from the street light pilot wire which puts the responsibility for control on the power network owner.

In New Plymouth, they are used to pick up the signals from the water meters.

That's unlikely, unless the water meters had power on them.

They don't say anything about using the streetlight mesh network.

Remember this is New Plymouth, Not Auckland and it was recently confirmed by a press release.

The linked ones are not in New Plymouth, simply some infomration that demonstrates smart water meters do not require a power connection as had been stipulated.

Well ... that's no fun.

If it's a homebrew protocol, and I'm not seeing any mention of any standard they're following, they'll have got it wrong more often than not [*]. Sit back and wait for the Black Hat/DEFCON/etc talk.

Having said that, apart from the lulz I can't see why anyone would bother attacking one of these things so you don't need it to be super-secure anyway.

[*] I'm not saying it's 100% certain they've got it wrong, it's just that statistically the track record of this stuff being done right is pretty poor.
