I should have been more precise, I don't doubt the claim about latency nor speed, but I really doubt that running an ipv6 stack requires less power than running the simpler zigbee stack.

Also one Thread advantage from that discussion made me laugh:

  safe as the internet, using proven IP technologies

But thanks you for answering me!

I haven't measured it, but: in a lot of embedded situations, the radio transmission time is the single biggest consumer of power. Thread+matter being more efficient on number of packets transmitted per command (the reason latency is lower) could actually translate to battery savings.

But does it translate to real world gains? I've developed a Matter (wifi) device and the stack is ridiculously chatty.

> as redundant and safe as the internet

Ahaha! Haaahahaha! i'm choking

(Joking aside, I get that their point is they leverage the decades of work into IPv6 rather than recreate their own ad hoc, informally-specified, bug-ridden, slow implementation of half of the IP stack, but man did that phrasing get me)
