mss110 7.0.0 by Meross Firmware: 7.3.37 Hardware: 7.0.0 not working

[JosephRDawson]

This integration has topped working on my mss110 on hardware version 7.0.0 running Firmware: 7.3.37.

The ability to control other Meross devices is not impacted.

I am running a HA Green on the latest fully patched version of HA.

I have tried the latest version of this component and all beta versions with the same result sadly.

I have provided logs and debug information to the developer but unfortunately at this point the developer has not had other reports of others having the same issue on the latest version of the software. For now I have been forced to switch to the cloud version of this integration until the issue can be resolved.

If you are also experiencing this issue please post here so we can let the developer know and hopefully with more people reporting it we can find the common thread to the problem.

All the best,

Joe

This integration stopped working completely, failed to load when I updated to the latest version of the integration today. Don't think it has anything to do with the meross device firmware, I'm on hardware 8.0.0, firmware 8.3.5, but restarting HA throws the following early errors while trying to load the new version during restart:

Home Assistant 2023.10.0, was running integration version Moonlight.2.2 (5.2.2) upgraded to Moonlight.3 and restarted HA

Probably a different issue from yours though, if your integration loads but then fails on one device type.

To avoid confusion and better clarify this issue/thread, the problem faced by @JosephRDawson is about toggling its mss110 devices (fw 7.3.37) from HA/meross_lan. Everything else is working (@JosephRDawson pls correct me if I'm wrong):

• the device state is reported correctly when you toggle the device with the app or whatsoever
• there are no apparent errors in logs
• when you toggle the device from HA it 'simply' doesn't toggle (no errors reported)

If someone else is using the same device/firmware and is experiencing the same issue or, on the contrary, everything is working, please report the behavior.

I am having the identical issue. Only with MSS110 devices. My MSS120, MSS620 and MSS510 devices work correctly in HA/MerossLAN. State changes in HA/MerossLAN are reflected correctly on the HA interface but attempts to change state through HA aren’t working.

Hello @aholmes55, If you could get a diagnostic from the device and upload a link I'd check it...not that I'm confident I would find the issue (I did inspect the diagnostic for the same kind of device from @JosephRDawson without any luck) But maybe something else could 'pop up' Thank you for signaling the issue so that this doesn't get stale too much.

Ugh - apologies. I wasn't on 5.3.0 which is working perfectly on all my devices. Thanks!
