Excellent communication from seller. Excellent packaging and documentation inserts! Bravo! I'm so very happy! With all the turmoil going on in Ukraine, I worried about getting it, but it came, and I'm thrilled! Swapping this unit for the WiFi module that comes with my Midea 12000BTU Window AC unit (MAW12S1WWT) was a breeze. After powering up the AC, the dongle started broadcasting, and after following the included directions, got it connected to my WiFi, and my HA server picked it right up. SO NICE to be able to change the settings from my phone WITHOUT it needing to "phone home"! THANK YOU SO MUCH FOR MAKING THESE!!!!
