I love the product I saw on YouTube called kc868-h32b. This is near perfect because it has allot of digital IO and relays, it uses RS 485 so It could be used with HMI, and allot of other features that could be used for industrial application. I believe it is capable of temperature sensing with PT100 temperature sensors, but I believe it would benefit from Using type K thermocouple temperature sensing, as well as having more analog input and output, specifically 4-20mA for scaled control and transmission. This combined with a customized Arduino program written for the ESP32, could be a powerful industrial PLC tool
