IoT - Freezer / Fridge monitoring

One or more DS18B20 Thermal Probe(s) to track the temperature in the fridge / freezer.

Board attached to the underside of a blank plate.

Plate attached to a Wiremold surface box.

(Probably didn't need the Extra Deep box...)

Minor issue noted: Mounting the ESP-Everything! centred on the plate kinda makes the USB port useless. But, there's about 10mm clearance either side. I should be OK just moving the board over.

Once the probes arrive, it'll be time to solder up the board, stick it next to the freezer & beer fridge.

Then testing begins.
