[FR] Local MQTT integration
Hi!

I've been searching a solution to control my LG Air Conditioners from openHAB for already a year or more probably. This is the only plugin that exists which can control both v1 and v2 devices without any major issues. I'm very grateful for this and it excites me a lot to achieve my long awaited goal.

Right now it is not possible to control accessories from openHAB with the existing bindings only in reverse direction (control openHAB from Homebridge). The only solution would be to implement all the REST API calls from openHAB for all my ACs but this would not provide instant status updates as well only with some polling probably overloading both openHAB and Homebridge.

So I would like to ask if it would be a great amount of work to implement simple get/set MQTT calls to a local MQTT server for each LG accessory to have control and status updates for any subscribers (eg.: openHAB). There is already an MQTT library there connecting to LG MQTT servers. 

Or is there any other solution that someone is aware of that I missed so far? Any help would be appreciated.

Thank you for this great and unique solution and for the continuous development.

Regards,
Zsolt.

PS.: Just another idea to create an independent solution to translate LG MQTT to local MQTT and make this available to all smart home softwares. This would be the first step toward this. (See e.g.: [Zigbee2MQTT](https://www.zigbee2mqtt.io/) or [ZWaveJS2MQTT](https://zwave-js.github.io/zwavejs2mqtt/#/)).
