Today we are looking for someone to write a piece of code for ESP8266/ESP32/Arduino that will be able to read data from a MODBUS device through a RS485 module. We are using a TTL to RS485 module with an ESP8266 and we want to read the temperature from a fridge that has a RS485 port.
We have already tried different things and they didn't work, so we're hoping someone could help us out.
We'll share the code we've used so far and the documentation from the sensor and we'd like to either correct us or write your own code and or hardware that would work in this situation.
If you can help us, please do reach out and we'll make sure we add something extra to our deal once we test your code and it works in our setup.
Thank you in advance.
