How to organize the interaction of the Bolid address system and esp8266 (arduino ide)?

Question

Arduino

There is a need (to simplify the maintenance of objects) to organize a simple interface for the phone (to see the status of addressable devices and manage them).
Implementing the user interface will not create problems, but there is a problem with communicating with the BOLID address system,
for example, getting the status of the loops (like shleifes) from the s2000-4 device
made requests to the Bolid company for five years. always refused requests to develop.
what bundle is needed to come to the object, connect to interface 485 on the device and process data on esp8266? what libraries? if we manage to do it, we will put the development in the public domain, we think that many people will be interested
