At the client�s site, they have Galactic inverter air conditioners. I was thinking of how to integrate them with Home Assistant � using ESP, soldering to the board, hanging three sensors around� Then I saw these Wi-Fi modules appeared, and even though Galactic wasn�t on the supported list, I decided to take a chance (I�d heard many brands are made in China at the same factory, meaning the firmware might be the same). And I got lucky! The air conditioner connected instantly. All available entities were exposed: Fan speeds Operation modes (heat, cool, dry, fan) Target temperature Louver control Even outdoor unit temperature. I�m really happy it worked out. The client is happy too - now they can control everything remotely. I decided to order three sticks for all the ACs. Thank you for a great product!
