it looks to be standard zigbee so I would expect it to work on the old one… but maybe not feature complete?
yeah I know it’s a "works for me’ post, but do my devices really need an IP address?
I still don’t really get the point of matter, Zigbee is doing me fine.
It’s the one I use, I would recommend a ZZH-P if they ever get released! Failing that I have heard good things about the sonoff stick.
I think this covers the basics.
Not sure if zzh is on sale at the moment, what are you trying to achieve?
