I am using ESPHome on my Synology VM and I am adding the ESP8266 wifi module with an USB (that has a button UART and Prog) on PopOS (debian distro). So, I select Prog and insert in PC, then go on this page, chose Plug into this computer, then find ttyUSB0 (sometimes ttyUSB1), press Prepare for first use the running installer. The problem is that error occur when it should popup the window for SSID and password. I pressed on 3 dots and same error occur.
You aren’t clear what you are flashing to the ESP-01, so should I assume that you are trying to make an ESPHome device?
You are using the same UART flasher that I use, but I always use “Plug into this computer”. Sometimes if that isn’t convenient, I will do a “Manual download” and use ESPHomeFlasher.exe on my PC.
Really sorry for confusion, I forgot to metioned that I chose Plug into this computer due using my PC with Linux (PopOs). I do not have windows on my PC, but I will try to add it in a VM machine.
Well, I am just trying to add it to ESPHome as I have already done with an ESP32, but there was working, after Prepare for the first use then WIFI popup, entered credentials and it’s displayed as ON .
Plug the esp device into the computer running esphome (probably the same computer you have home assistant on). Then choose the option “Plug into the computer running Esphome dashboard”.
I run EspHome on Synology NAS and usb stick is in PC. I will try to ad it in NAS see if it is working for ESP8266, due for ESP32 was working with no problem.
