Dude, that is way cool! I am unable to test this all, so I am very happy that you are trying to add this.

I made 2 remarks on your PR. Could you have a look at them?

[cnelsonsic]

I have some changes I'll be pushing in a few moments, but I don't see your comments on this PR.

[theyosh]

Hmm, not sure why... but here is a screenshot made of this PR...

[theyosh]

Does this show up the two remarks?

[cnelsonsic]

Also, the Makefile change isn't strictly required, I just found it useful while I was testing. I can break it out into another PR if you'd like to polish that elsewhere first.

It turns out that the bluetooth scanning in TerrariumPI is really pretty nice, I apparently never really had it working in my setup.

This is pretty well finalized, can you review this again?

And if you could also update the composer example in: https://github.com/theyosh/TerrariumPI/blob/main/docs/_tabs/install.md?plain=1#L79

And if the device looks the same as the 'original' MiTemp, then you could just copy https://github.com/theyosh/TerrariumPI/blob/main/docs/_hardware/mitemp_sensor.md?plain=1 to lywsd03mmc_sensor.md and replace the names.

Then the documentation is also up to date.

Hi, do you have time to update the documentation? If not, I can do it also.... not a problem. Then I can merge this PR

[cnelsonsic]

Yes, I'll be working on docs today.

This device actually has a smiley face so I don't know if you want to update the photo as well.

Thanks a lot! And merry Christmas
