I have been trying this for weeks. I want to integrate an old Lutron Homeworks H4P5-h48-120 processor with Home Assistant. I gave up on raspberry Pi. I installed on a mini PC with Moxa Nport 5100. Baud is 9688, data bits 8, stop bits 1, parity none, Flow control RTS/CTS. I can telenet to the moxa, but cannot get info back from homeworks through the serial port. Commands do not work with the home assistant integration, although it appears to connect to the moxa and send the commands. Nothing happens and no reply from homeworks. Can anyone please help? Thank you so much.
