I first purchased one of these for my KeepRite Ductless Mini Split. I discovered the USB port internally when I was cleaning it I then found this little device and ordered. It came rather quickly considering what is currently happening in Ukraine. I plugged it in and logged into it's AP/Wifi mode and set my IoT network up. I added it in Home Assistant via ESPHome and everything populated. I am able to control all functions from Google, Home Assistant, etc. I ordered a second when I had another Mini Split installed, the Kerr brand. This also works 100%. It actually even populates the power sensor and I'm able to calculate kW/h now (source: https://www.tindie.com/products/smartlightme/wifi-dongle-for-air-conditioners-midea-electrolux/#product-reviews)
