HAIFUAN Gateway HUB for Bluetooth Locks, Work for HFAD6300B, HFAM10B, HFAM20B (G2)

Is there api access so i could connect this to my own home automation software?

I was sent the g1 hub which apparently has been upgraded. there are no instructions on how to link it to my alexa or haifuan smart locks. please help

Will this work with a Tru-bolt bluetooth dead bolt?

Will this work Google home?
