Hi,
I own a multisplit AC "Samsung WindFree Comfort S2". Just sharing a few adventures with it after a few months of usage. I am a smart home enthusiast and IT-guy, so I know what I am talking about btw.
Issue 1: A few weeks after initial setup, one of the room units dropped from the app (it disconnected and never reconnected. Not even after a power cycle). I had to delete it in the app and reconnect it manually.
Issue 2: I disabled the LED Display (tried it in the app as well as using the remote) and after turning the unit off and on again using the app, the display is back on.
Issue 3: The app feels very bad in UX terms. Constantly "downloading" the device plugins, requesting permission for authenticating again and again sometimes I open the devices, ...
Issue 4: Once I needed to powercycle the whole system as it did not accept commands neither from the remote, nor from the app or even using the local "power" button on the indoor units. It was beeping but nothing happened when I used the remote. All at once. As if the devices MCUs hung up simultaneously. The App did not even offer other operation modes than the currently selected one.
Issue 5: When I switch the indoor unit off (no matter which way), and switch it on using the physical power button on the device, it always is set back to "Auto" mode.
Issue 6: Occasionally the unit "forgets" it's ventilation settings when swicthed off/on. Not always, but sometimes.
Issue 7: The Auto mode. This alone would be enough. That AI-Crappy-Bullshit-Auto-Mode is a curse.
It constantly overrules your settings: Imagine, you set the auto mode on a traditional AC to 23°C. One would expect the AC to cool when the room becomes too warm and heat up if it becomes too cold.
In other words: Set and forget. No matter if winter or summer, the room has 23°C.
Not with samsung!
The "Auto mode" is hard-tied to an Artifical "Intelligence". You can not use Auto without AI (except if you disconnect the device from Wifi losing all smart features). The remote has a dedicated AI button (besides the mode cycle button) that does simply enable "Auto" mode.
In Auto mode, the device constantly sets the target temperature to ridiculous values. 25°C in my case. Every few hours. It decides that per room, so virtually always there is a single unit that wants to heat in summer leading to all other units not providing cooling because obviously heat is priorized over cooling (because the system can not provide both at the same time of course).
I don't know if any samsung responsible ever gets to know this and I am pretty sure nobody actually will do anything about it, but I wanted to share the pain, maybe it helps some others, not to decide for samsung as long as especially that "AI" system is such a big issue.
Possible Quick wins for samsung:
- untie Auto and AI. Let us disable that AI ***** feature if we don't want it and give us a traditional auto mode.
- fix the storing and reloading of settings in all on/off cases
Thanks for reading through here. I needed to say this.
