Hi,

Nice project. This is something I had in mind when getting the modules. I now only have some of the modules prepared for (outside) temperature reporting. Which is published to my mqtt broker running on a NAS.
Having a look at the device on the photo, attached to the door I do not see anything soldered to it? So only having one magnet makes this work? Or is the other part hidden behind the module?
Would be great if you could share some more details. So, the not so technical ones around here, can try to create this as well

Thanks
