Same here,
failed during the night (Europe), was working yesterday evening

[midadami]

Same, everything was working fine until few hours ago. Same error.

[dpacecca]

I also have the same error, lost connectivity around 2hrs ago.

[chrsc59]

restoring to core 2022.12.8 did not help, same error after HA reboot, or reload of the integration

btw, the Meross app (Android) works with the devices

[varactor]

Same issue here, it happened before any updates. Restarted HA, updated to latest core and still same issue.

Error same as original post.

I reloaded the integration an that did not work, I think the API address is down, iot.meross.com

[chrsc59]

I reloaded the integration an that did not work, I think the API address is down, iot.meross.com

I'm presuming it is not down as the Meross app can control the devices from the cloud

[Raul-7-7]

yeah, also the devices work with Google Home so the API seems fine.

[Odinlistening]

Confirming same issue here. All fine yesterday evening - no updates or system changes.

[Raul-7-7]

Hmmm, since no change, then maybe Meross has changed something in the API payload?

[komima]

It may be the Meross api has changed, and no longer returns the skill_number field. Response is directly used to construct the device info class, and missing fields break the integration.

https://github.com/albertogeniola/MerossIot/blob/0.4.X.X/meross_iot/http_api.py#L417

For now I managed to resolve the issue by changing the meross_iot library model/http/device.py file manually (from homeassistant python environment, use python -c "import meross_iot.model.http.device as d; print(d.__file__) for file location), since that field seems not to be used anywhere important for homeassistant.

# skill_number: str, (for arg, comment out)
self.skill_number = "123" (for assignment, just use anything)

[albertogeniola]

Hi all,
yeah, Meross API changed. Tracking this issue here

--- EDIT ---
I'm working on that as we speak. I've already patched the low-level library. Now I just need to wait for the testing pipeline to run and release the new MerossIot library. Then I need to release a new Meross Integration on HACS. It'll take a couple of hours in total. As soon as the new version is online, you'll need to upgrade the integration and restart your HA.
I am sorry for the inconvenience, but as you can see, that's something we don't control...

[albertogeniola]

Hi all,
the beta release that addresses this issue is ready to be tested (the lower-level library has been released right away). I need some volunteers to test it and report back if that solves the issue.

You can enable "beta releasaes" directly from HACS. You'll find a release named "Prerelease v1.2.7rc1": that is the one to be tested. Update your HA component, restart HA and please report back if that's working again. As soon as I get some confirmation, I'll proceed with producing the stable v1.2.7 release.

@albertogeniola Problem solved for me! thanks so much!

[tomrush]

@albertogeniola I have just updated and tested on my garage door opener. Everything looks to be working correctly on my simple setup. No errors or issues in the log.

Thanks for your prompt fix for this issue.

[merlin-zaraza]

@albertogeniola Works for me. Thanks!

[albertogeniola]

Thank you guys. I've released the v1.2.7 right away (it's exactly the same as 1.2.7rc1).
We just need now to "spread the voice" to all people who are using this integration around the world.

I't just too bad Meross changes its API signature keeping the same api version number, which just break existing things.
Also, this time we've been lucky: I'm currently on hollidays and I had my laptop with me, so I could fix this in a few hours.

[Odinlistening]

Thank you so much for incredible speed of response.

[chrsc59]

Working now, Thanks !

[Tristano67]

Hi ! I think it's my first comment on GitHub, but I really need to say THANK YOU !!!
I'm using your Meross integration with some automations in my house, and you resolved this issue so fast !
BRAVO @albertogeniola and all people who worked on it

[Phishing-Fish]

Like what was previously stated, thank you so much for the quick response to address this issue. Your work is greatly appreciated.

[davecowell]

I am trying to update but HACS still shows 1.2.10 only and no update.
