Add Support for LGMV

[cbird808]

Is your feature request related to a problem? Please describe.
With the present, amazing thinq support, it is not possible to get access to the data from the many sensors in an LG HVAC system.

Describe the solution you'd like
LG Monitoring View is a wifi dongle and App that allows you to access many sensors in LG HVAC systems. It would be great if I could get access to the LGMV wifi dongle in HA and use the data, such as compressor step to adjust the hvac mode, fan speed and set point. Another example would be to use the temperature going into and out of the coil to determine how long to run the fan after the set point is reached and the compressor stops.

Describe alternatives you've considered
Thinq does allow you to see some data, but LGMV let's you see everything.

Additional context

Is this device detected in some way from integration? Can you attach integration diagnostics?

As a refrigiration technician i strongly advise against this idea, reading sensors is fine, but if you don't know what you're doing the life cycle of the compressor will be significantly reduced by intervening to much. Exterior temperature would be interesting tot know. But none of this would work, since they API does not expose them natively. To usefully circulate remaining heat, just make a node red automation or regular, to switch to fan mode for 5 minutes before turning "off". Op do 1 feb 2024 09:25 schreef ollo69 ***@***.***>:

I don't know the answers to your questions. I run simulations and analyze data, which is how I knew how to run containers to get ha running, and clone your repo, but I have no comms skills.

I do know that I connect to the lgmv locally and directly via its wifi radio from the free lgmv app for Android and Windows. There is a way to control the hvac unit through lgmv, but shockingly, it's buggy and not reliable.

If there's anything I can do to try to get the info you need, let me know

Lgmv doesn't give you access to any controls that you don't have access to on their thermostats, so I don't see why owners need to be protected from it. What it does do is provide a wealth of useful information for keeping the unit in good operating condition, provide early warnings, and improve efficiency.

Being able to see monitor all of the sensor output from your hvac is valuable for more than hvac pros. That being said, hvac pros could also benefit from what I've requested. Lg hvac owners or pros could use the advanced hvac sensor data with ha to warn of decreasing performance or efficiency and proactively service equipment. That's a valuable service that could be provided to the majority of people that aren't going to mess around with ha or understand their hvac and would make the minority of highly tech proficient hvac pros highly competitive.

In the case of lg units, they just plain put too little effort into their software, so without ha integration, I'm faced with either a minimum of 3-4 degree temperature swings with the unit "running like they intended", or wiring an ecobee to the unit and it running full blast till the set point is reached, often short cycling.

The ha alternative, of using the ecobee to trigger lg hvac actions while allowing it to run according to its programming is a good compromise. Using lgmv to see that the hvac is not running optimally and addressing that by either proactively servicing or improving efficiency with automations is better. It's not like lg is issuing over the air updates to address their software issues, nor are their units running optimally, nor do they implement a sophisticated monitoring system to prompt for service.

It seems this LGMV does not use the LG ThinQ cloud platform but communicates locally using the WiFi dongle
