It's exactly what I wanted Shipping was quick and the device was well packaged. The physical USB port (on the Senville head unit) had some plastic "keys" preventing a standard USB plug from being inserted. I cut them off with an Exacto knife and then everything fit perfectly. The provided instructions were very clear; I was up and running in Home Assistant within minutes. I can now also control the heat pump from HomeKit, and that makes me extremely happy! Great purchase, worth every penny. (source: https://www.tindie.com/products/smartlightme/wifi-dongle-for-air-conditioners-midea-electrolux/#product-reviews)
