I am getting started with Homey Pro and I would like to establish the following:
- I have several LG Thinq2 units in my house (PC12SQ NSJ and PM05SP NSJ)
- The internal temperature sensors are not very useful, because they are internal
- I have bought and installed SONOFF SNZB-02 Zigbee thermostats
- All components are registered to my Homey Pro and put in their relevant zones
- Communication between Homey Pro and the devices has been tested and verified
I would now like to control an airco-units’ status and functions based on temperature and humidity info coming from the relevant thermostat(s). How do I make the airco unit ignore its internal temperature sensor and just rely on my Flow commands?
Or am I completely missing the point on how to combine these two components?

AFAIK that’s only possible with a hardware modification: [GitHub - JanM321/esphome-lg-controller: Wired controller for LG HVAC units using ESPHome and ESP32](https://github.com/JanM321/esphome-lg-controller)
But I don’t think it’s supported by Homey.

That is of course not the answer that I was hoping for 😉, but it is an answer (and a fast one at that) so thank you for that!

To make you feel better…
I tried with [vthermo](https://homey.app/en-us/app/no.almli.thermostat/VThermo/) and got very far with automating/reacting to temperature changes to start/stop the airco with the [Sensibo](https://homey.app/en-us/app/com.sensibo/Sensibo/) app for Homey (Sensibo sky is an after market device with an app that allows me to (remotely) do everything with any airco).
Vthermo can automatically read temperature value of a sensor or thermostat in one or more zones and eg. average them, then activate and thermostat/fan as well (or you can create more detailed flows)
Even with Vthermo I ended up with so many flows to achieve my preferences that I deleted them all.
Now I’m using just Sensibo without automations in Homey and my life is simpler. But the Sensibo costs €75 or so.
I do have some simple flows that check if the airco is on and then disable or enable the fan.
My bottom line: best stick to a dedicated solution/app which is designed for that.

Thanks @Rrrr , it seems that letting the airco do what it does is the best way forward.
On the other hand… I could of course use the external sensor’s temperature readout to increase the desired temperature on the airco if I find that it shuts down too early (as it reaches its temp based on internal sensor).
Funny how explaining a problem that you are struggling with to an other person actually often brings you closer to a solution 😃
