2026.4.0 Upgrade - Emporia Vue 2 Problem

ESPHome
1

I have 3 Emporia Vue 2 devices flashed with ESPHome in Home Assistant which have been working fine for a year or more. I flashed ESPHome version 2026.4.0 to all 15 of my ESPHome devices today including the 3 Vue 2 devices. All devices appeared to flash fine and were successful using update all. All the Vue 2s show as off line but all other devices flashed are working properly. I attempted to Downgrade ESPHome back to 2026.3.3 but that did not help. Any thoughts or suggestions?

Right there with youā€¦

Not only are they ā€˜offlineā€™ in Home Assistant, they are also not showing as connected to wifi. Both within my router (Ubiquiti UDM Pro) and within the YAML I have static IP addresses defined.

Both show offline since around 10:30am when I ran the update.

Both are in the electrical panel, so I pulled one cover off and I have two green lights on the device. I tried powering off, but no change. I have captive_portal: defined, but nothing showing in my wifi to connect to there either.

Gemini is telling me it is likely related to being defined as framework esp-idf and I should use arduino. Stating itā€™s likely run out of memory on the latest version of esp-idf.

BUT, that is going to require I pull the devices and flash with a serial device. Before going that route Iā€™m hoping thereā€™s an easier fix.

Funny enough the language around the latest changes and defaulting to esp-idf would counter what Gemini is suggesting since the binaries would be smaller not larger? Mine was already defined as esp-idf (or at least my yaml is defined as such.

esphome:
  name: emporiavue1
  friendly_name: vue2_1

external_components:
  - source: github://emporia-vue-local/esphome@dev
    components:
      - emporia_vue

esp32:
  board: esp32dev
  framework:
    type: esp-idf
    version: recommended

Why the Change?

ESP-IDF (Espressif IoT Development Framework) is the official development framework for ESP32. It offers several advantages:

  • Smaller Binaries: Up to 40% reduction in binary size
  • Better Performance: More optimized for ESP32 hardware
  • Custom Builds: Firmware is built specifically for your device configuration
  • Active Development: All ESPHome developers use and test with ESP-IDF
  • Latest Features: New ESP32 features are available in ESP-IDF first

Having the exact same issue. Did you manage to get it working yet?

Sad to say I am in the same boat on one of my Vue 3 units. I always do one at a time and check them in case of an issue, so I caught it after the first and have NOT killed the second one until thereā€™s a known fix.

I had to take the offline one out of the panel after attempting to reset power (I know which breaker it relies on)ā€¦ no good. I donā€™t see either of the green lights when it has power, so itā€™s pretty unhappy for sure.

I assume Iā€™m going to have to go all the way back to pogo pins and serial to get this unit going again?

5

nope, not yet. I haven not continued trying to fix them at the moment.

Is yours offline from WiFi also?

6

In the same boatā€¦
I have 3 of them and all of them are not reachable.
It is a major job if I have to remove them to use the serial adapter to reflash them.

7

Yes, both on Wifiā€¦ but Iā€™m going to attach ethernet to the dead one and see if I can find signs of life. Over on GitHub there are others reporting the same situation and, at the moment, appearances that they might be bricked since one person canā€™t get anything via serial either. Iā€™m about to try as well.

8

Yeah mine is wifi too. But I donā€™t assign a static IP in the config like you do. I assign a fixed IP in Unifi on my UCG-Max. Donā€™t think that really matters with our issue though.

9

Following the source referenced at the top of my yaml from where I got it, there is also an open discussion topic regarding this where the user switched to arduino framework AND ESPHome 2026.3.3 which appears to have fixed it (or at least a workaround for now)

10

I also do the Unifi-based ā€œstaticā€ and, yeah, doesnā€™t help our situation, sadly.

11

I have one connected via Wi-Fi and one via Ethernet. Ethernet is still responded to ping after a power cycle but the one configured for Wi-Fi is no longer responding to ping after a powercycle. I rolled back ESPHome and tried to reflash from the pins with no luck.

12

I just tried rolling back to 2026.3.3 and flashing over wifi by powering it on right before trying to send it seeing if I could catch it waking up, after a handful of times I gave up. My next attempt would be to do via pins directly ā€˜as isā€™ and then following ihexley from the emporia vue github and swap to android framwork.

13

I tried the same and ended up with it back on the bench to reflash from the pins and have had no luck. My frame work has been set to esp-idf for awhile, should this be changed to android?

14

arduino, yes, Iā€™m back online with my first vue2.

Super janky repair, didnā€™t want to disconnect all the wires.

  • Unplugged main power
  • Recompiled in esphome (for manual file download)
  • Connected serial adapter, grounded the boot pin
  • Plugged in USB to laptop
  • Flashed bin from esphome

Yeah, reverting to type: arduino and 2026.3.3 helped me. @dmtalon Are you on 2026.4 with type: arduino?

16

On 2026.3.3 or 2026.4.0 ?

17

no, I went back to 2006.3.3 first, tried reinstalling via wifi w/o luck.

After opening up the case, I just went ahead and switched to arduino framework since it was ā€˜knownā€™ working solution with 3.3.

about to flash #2 now

18

Ok, that was my case too. WiFi was down so direct reflash over UART helped, but I downgraded to 2026.3.3 and arduino in one step, so I am not sure which one helped or both needs to be addressed.

19

OK, both my Emporia Vue 2ā€™s are back up with ESPHome on 2026.3.3, and an update to the yaml configuration changing from esp-idf to arduino.

Just commented out what I had, and added the replacement.

#esp32:
#  board: esp32dev

#    version: recommended

My Vue3 units were working previously on 2026.3.3 with type: esp-idf. I gather the switch to arduino is a workaround to get 2026.4.0 working?

I parallel installed ESPHome 2026.3.3 in my HA instance for the time being until the dust settles on this fully (so I have both releases available). The one I didnā€™t flash Iā€™m leaving alone and I have the bricked one on the workbench now getting set up to reflash it back to 2026.3.3 via UART (a process I was hoping never to have to revisit after doing this the first time in July).

Fingers crossed. I ordered another unit to have around as a spare in case something like this happens again. I can take it off the shelf, flash it to last known good and swap it in the panel so I donā€™t lose hours of data gathering like has been the case today. Iā€™ve needed a spare around anyway in case something dies more thoroughlyā€¦
