I can reproduce the problem locally with the newest (2024.5.0) ESPHome version. It seems that they changed something so the project does not fit into RAM anymore -- which is strange. This needs further investigation.

If you have the chance to compile the project with some older ESPHome version this might be a solution. As far as I know there is no (easy) way to downgrade the HA add-on.

ESPHome 2024.5.0 might be broken in a more general aspect, people even suggest to revoke this version

[helmuteke]

so i have to wait i think ?

I have rolled back my docker to 2024.4.1 and disabled automatic update through Portainer, other people called version 2024.5.0 as a royal PITA

Same on my side, I rolled back ESPHome from 2024.5.0 to 2024.4.1 and reinstalled hn's ginlong-solis file on my ESP8266. Afterwards all was working fine again.

[helmuteke]

Can someone point me how to downgrade , i use esphome in HA

I am using ESPHome in HA as well and before installing an update for addons HA is creating a new Backup when you have selected the checkbox.

In "Settings->System->Backups" you should then see a backup called like "addon_xxxxx_esphome_2024.4.1". Click on it, set the checkbox and restore it, afterwards everthing should work again normal.

[helmuteke]

This version was first instll 🙁

[hn]

They released 2024.5.1. I see no relevant changes for this problem in the changelog and people are still complaining about defunct devices. Did not try to compile solis-emw3080.yaml yet, but probably not worth a try.

[helmuteke]

someone a other solution for this problem ?

But how can i downgrade please . . . it's HA addon

[hn]

• Setup Build environment (Python for Windows, Debian in a VM/WSL, a Raspberry Pi or whatever you like)
• Install ESPHome manually but make sure you use pip3 install esphome==2024.4.1 for the older version, double-check afterwards with esphome version
• esphome compile solis-emw3080.yaml
• If successful, the UF2 image can be found somewhere in path ./.esphome/build/ ... /.pioenvs/ ...

(not tested, surely something is missing ...)

[helmuteke]

i found this handy repo : just compiled my uf2

Still an issue in 2024.5.2 My last working update was in 2024.4.2

My Slimmelezer+ was sucessfully updated to 2024.5.2

To fix this I removed the webportal access, it seems to bring down the firmware size enough to fix the issue. So not a fix for those who reley on the webportal, but for those using ESP home/Home Assistant it works fine.

# captive_portal:

Thanks @timh77 :) I personally don't like these kinds of workarounds, but this is probably the best option we have today.

[hn]

2024.5.5 seems to work (even with captive_portal=enabled) again. I haven't investigated this in detail to see if this is a coincidence or if there was a specific fix for it.

[timh77]

I guess it's related to this change in 2024.5.4 (May 28)

[web_server_base] Bump ESPAsyncWebServer-esphome to 3.2.2 [esphome#6797](https://github.com/esphome/esphome/pull/6797) by [@jesserockz](https://github.com/jesserockz)

Previously it used version 3.2.0. Just a minor change was included, but I guess that resulted in a much smaller filesize.
