temperature

Howdy all. I just got my AD410 doorbell installed and my family has noticed that it's hot to the touch. I decided to take some measurements and was rather surprised by the temps I'm seeing. My entryway is in constant shade, the doorbell is never in direct sunlight, and the ambient temp outside...

I have my Equipment in a rack enclosure. The enclosure is vented and I can install fans but my ideal is to have some sort of temperature data logger but with an alert; maybe via email or something like that. I'm wondering if anyone may have some recommendations?
