No. 1869	Re: Question about SMG 5400	2022-12-06

One more question: The sauna has an RS 485 connection with 3 wires. On your module I only see a 9-pin serial connection. How should I connect the 3 wires to the 9 pin input? Are there standard cables for this? Thank you Bastiaan > Bastiaan wrote: > ------------------------------------ > Hi, I am new to Modbus, and want to make sure I understand how it works before I buy the wrong device. I would like to control a sauna with modbus-RTU with my home automation software (Home Assistant). Home Assistant is running on a small computer connected to my network. Home Assistant has Modbus support. Can I use the SMG 5400 to convert RTU to TCP and connect to the sauna from Home Assistant? Or am I missing something in this setup? Thank you for the advice, Bastiaan
