Works fine with AC VIVAX, integration into Home Assistant was simple and easy, I just needed to cut out the rails of USB. In addition to standard functions like on-off, set temp, set fan speed, this AC is having additional functions that are not accessible via Home Assistant integration. Most interesting is "SILENT" mode that is reducing the speed of fan to minimum, even less than SLOW. Climate card in Home Assistant is showing "SILENT" beside "TURBO" but the proper command is not issued to or is not recognized by AC.
