Description
making a Marstek Venus E V2 battery control dongle via the RS485 port for Home Assistant
I used an ESP32 https://www.amazon.fr/dp/B0D8T7LZF2?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_3&th=1 and a MAX485 TTL module https://www.amazon.fr/dp/B07DK4QG6H?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_6
The plug for the RS485 port is a 5-pin SP17 connector https://s.click.aliexpress.com/e/_EuaLIiy
