NaN for Temperature, Humidity and Battery Level from MS100EU

[Tongo91]

Hello and happy new year. I get a lot of "NaN" Errors from my Temperature and Humidity Sensors that are working over the MSH300 hub (Firmware 4.1.35 and hardware 4.0.0) Sometimes I get less and sometimes a lot more of them, is there any reason for those Errors? In the Meross App itself everything looks normal.

Here are some Logs: [02/01/2023, 16:12:53] [homebridge-meross] This plugin generated a warning from the characteristic 'Battery Level': characteristic value expected valid finite number and received "NaN" (number).

Hi @Tongo91

Can you update to the beta version of the plugin and show me this logging again? you should see more red entries this time (they are not actually errors).

I need to be able to see these red entries.

Thanks!

Hi, thanks for the fast reply, I did the update now and waiting for the NaN Error. Currently everything is reporting normal since a few hours, as I said above sometimes it works and then I get those errors over a few hours.

I will update as soon as I see the NaN Logs again including the red entries then :)

Here are the latest logs with the red entries around the NaN Errors, I hope that helps.

Hi @bwp91 do you need any further information?

[Tongo91]

I will revert my version for the stable version now, to clean up my logs and stop the excessive logging. If you need any further information, I am ready for updating to the beta again.

[bwp91]

Hi @Tongo91

sorry the delay in replying. thanks for the logs - please check the latest version of the plugin i have just released :)

[Tongo91]

Hi @bwp91

no problem, thank you for looking into it. I updated my version now, thank you.

[bwp91]

please let me know if you see any more messages like this. i’m starting to doubt my fix now 😅

[Tongo91]

You are right 😂 I just checked the logs right now and the NaN message still exists.

[bwp91]

Newest version should properly fix this now!

[Tongo91]

Hi @bwp91,

looks good, I can't see any NaN errors anymore. But the red additional logging is still active, maybe you should disable that again for the stable version?

Thanks a lot for the ongoing great work!

[bwp91]

You are correct - sorry - forget these things when I don't own the device myself. Please see newest version!

[Tongo91]

That worked and no more errors. Thank you!

[bwp91]

Amazing! thanks for reporting this 👍
