Modbus TCP Server

Hello Folks,

I am wondering if it is possible for openHAB to not only act as Modbus Master (aka Client), but also as Modbus Slave (aka Server).
According to the Modbus Binding Page: https://www.openhab.org/addons/bindings/modbus/ this binding is only for Modbus Client.

I found this tutorial which uses node.js and OH REST API from 2017. i guess this is still the way to go, right?

Cheers,
Stif

The docs tell the truth here.
