Hello, I would like to know if it is possible to use the RS485 port to receive the reading data from a pzem 017 dc to integrate with the Home Assistant using MQTT. Thanks.
no, the RS485 of H32BS is "slave" mode, use for integrate by other "master" device.

Hi. Probably it's possible with COLB, but only with Node-Red. Sadly there is no flow available for this. I have a Kincony energy meter and a COLB device, the data flows in to COLB but cannot use in Home Assistant without the above mentioned Node-Red flow.
if you use Node-Red on raspberry pi, i suggest you use a USB-RS485 adapter, let pi connect with kincony power energy meter directly, the meter use by MODBUS protocol , easy to integrate with home assistant, not need via COLB.
