SoCal Electric meter monitoring

Long story short. I have a RAVEn Rainforest Automation, Inc RFA-Z106
RAVEn RFA-Z106
It works great and I wrote some code to just log the data into a database and provide a web interface to view the chart of power usage. The problem is the device has long been discontinued.

My power company does specify that you can connect a Zigbee device to it for monitoring but stumped how to do this with this stack?
SCE HAN FAQ

I’m trying to build the same functionality and wondering if the CC2531 Zigbee device would work for this. I have flashed the device but wondering what it the API/Interface to the COM port. The RAVEn device was XML send/receive

Can zigbee2mqtt work as a receiving device to collect the data from the power meter?

Thanks
