Zigbee Smart Energy Protcol

I have been using an Emporia Vue Utility Connect for a while now and while that is cool, I rather not have all of my data sent to their servers. I saw someone made an ESPHome firmware for it which sounds interesting, but it got me thinking thinking, does any zigbee stick on the market support Zigbee Smart Energy directly, which seems to be a non-standard protocol over zigbee?
