I want to use Home Assistant as an extension to an existing system that operates with RS422. I have already gone through some posts in this community, but I couldn’t find anything that I thought would be a good starting point.
If possible, I would like to use Ethernet. We will place a converter between the copper wires and the network.
What should Home Assistant do?
As an example, when a helper, such as a input_boolean is switched on, a hexadecimal command should be sent:
Turn on input_boolean: send command “\x08\x22\x00\x00\x00\x02\xD4”
Turn off input_boolean: send command “\x08\x22\x00\x00\x00\x01\xD5”
If the command is sent by another device, the helper in Home Assistant should also be toggled, so:
When “\x08\x22\x00\x00\x00\x01\xD4” is received: input_boolean on
When “\x08\x22\x00\x00\x00\x01\xD5” is received: input_boolean off
How should I approach this situation?
