I have previously flashed ESPHome on several devices, but am now very confused because I cannot install it on another device.
I inserted my new device, a HiLetgo ESP8266 NodeMCU, into a proto-board, attached a micro-USB cable to it, and plugged the other end into my computer. I launched Chromium, went to web.esphome.io, and my computer readily connected with the NodeMCU (a window showed ‘CP2102 USB to UART Bridge Controller (COM23) – paired’).
I then clicked ‘Prepare for adoption’, saw the blue LED on the NodeMCU flash several times, but was then shown a window with ‘Failed to initialize’. I tried holding down the flash button as the device was plugged into the USB, holding down the flash button until I saw the error message, and tried two USB cables. Now what???
