Supporting SLZB-06M

Are there any plans for supporting devices like SLZB-06M? Currently, I have usb dongles which gets forward through ser2net using rfc2217. I have tried both tcp:// and socket:// no luck.

I am aware of using zigbee2mqtt but with the amount of devices i have, it is a lot of work.

What exactly is a lot of work?

Setting up the mqtt channels, having a separate service running for mqtt broker.
