| Connect the logic converter to 3.3V on the LV side |\n| GND       | GND    | GND | Connect any ground from the ESP32 to the ground of the logic converter low voltage side |\n| GPIO16    | LV1    | -

You can now connect this ESP to Home Assistant and control it from there.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FDomiStyle%2Fesphome-panasonic-ac","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FDomiStyle%2Fesphome-panasonic-ac","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FDomiStyle%2Fesphome-panasonic-ac/lists"}
