i have checked your video, i think all your device have connect with one RS485 bus , right? because video not clearly to see wire.
1. one RS485 bus can't use multi "MASTER". your home assistant installed on a Server, the server's RS485 is "MASTER". E16S, HA , RS485 sensor all are "SLAVE". if this system structure is ok, we can design a standard modbus protocol firmware for HA pcb. then you need to use "LATCH" button, if you use push button, it need hold on more time, can't too quickly. Because modbus "pull" speed can't too fast.
2. thanks for suggestion for i2c extend board. do you think i2c 8CH relay or i2c 8CH input board is ok? or maybe 4CH or 16CH?
