2026.4.0 broke the devices, the main dev on the emporia-vue-local project updated the source code Sunday and got it working. 2026.4.1 is also working. Devices have to be connected back to USB TTL and re-flashed. No Yaml config is needed.
Fixed your issue with no changes to your YAML? Or did you have to make changes?
HELP. So I finally got around to pulling my Emporia 2 devices from the Panels and started flashing them. The first two went perfectly flashing them with the image downloaded from ESPHome “Plug into this computer”. I can connect to the USB device for the third Vue 2 device but it does not flash and I keep receiving this message.
“Failed to initialize. Try resetting your device or holding the BOOT button while selecting your serial port until it starts preparing the installation.”
Other than grounding the IO Pin to the chip to enable boot loader is there something else I might need to do??? Not sure what the issue is?
Check to make sure transmit and receive pins aren’t reversed. It happened to me and gave me the same error. After correcting I was able to flash. Some of these boards have the transmit / receive mislabeled.
Are we able to upgrade as long as we have the following settings?
esp32:
board: esp32dev
framework:
type: arduino
Or is something else required?
No special settings required, the update to the latest version works as is.
can you confirm which build you are referring to as "the latest" ?
I've been super hesitant to upgrade following the 2026.4.0 issues.
Others have already confirmed 2026.4.1 fixed it.
Is this still an issue for anyone flashing with 2026.4.5? I've been trying to flash my new vue 3, but wifi never connects, flashing with ethernet will connect, but then it can't connect to update and home-assistant doesn't see it. I've flashed back to the stock vue firmware for now.
Still show OFFLINE for me
Any updates or Fix solution
Latest ESPHome works flawlessly again. Wifi shouldn't be an issue at all if you put the wifi settings in ESPHome. If you need help, please let me know.
Just flash the latest ESPHome through a USB to serial device.
Ok. Thank you, will try today
In case you are interested. I was working this ESPHome Emporia Vue component recently GitHub - rosenrot00/emporiavue: ESPHome component for local Emporia Vue energy monitoring with Vue 2 and Vue 3 support. · GitHub

Will take a look. TY
For some reason Emporia Vue not connecting to my PC by usb to serial device. It's showing connected, but then it's said no connection. I tried to connect IO00 to GND, same result. Any thought what I am doing wrong. TY
Resolved. On Emporia Vue board RX to RX and TX to TX need to be connected not rx-tx and tx-rx.
And I am back ONLINE
Thank you, everyone for help
