I have LG SmartThinQ version 2.3.1800 installed on my Samsung Galaxy S9+ cell phone.
I recently had an LG Multi F - 4 Ton mini spit air conditioner installed with 3 indoor ac air handler units (2- LG LMN249HV & 1- LG LMN159HVT) I have to say I am very disappointed to find out that the Wifi on the indoor units don't connect automatically. Then, when trying to use the application - it doesn't reconnect either. I have to shut off circuit breaker power to the outdoor unit to get these to connect back to my Wifi through this application. An example of this is my router was offline for 18 hours. Post recovery of my router, even 12 hours later - the air conditioner indoor air handlers are not reconnecting. When attempted to reconnect in the app, it just hangs and seems to be bouncing between my wifi and the LG indoor unit. Doesn't stay connected or re-register the product. This is VERY inconvenient and must be fixed! I don't know if it's the mobile application or the actual indoor air handlers that are the problem, but this is unacceptable to be resetting a circuit breaker to get them back on WIFI.
