Made slight adjustment to copper traces on PCB design and printed a UV mask. Also made a slight update to the software to hopefully improve TCP connections.
Updated housing model to have flanges to screw into the wall. Printed in translucent orange (best color) PCTG and found 4 perfectly sized screws in my jar. Updated the Pico web server code to show the server start timestamp, hide the historical data by default, and update to the final 30-minute delay in datapoint recording. 
Designed 02007-002 and -003 housing components. There are holes in the box for the antenna (unnecessary), USB-C connector, motor wires, and sensor wires. 
Designed circuit schematic and laid out PCB design for the control unit. 
Spent a while getting the connection to the time server working. Attached UI image shows a datapoint every second for testing purposes, but will probably be every ~30 minutes in the live version. 
Got the preliminary software mostly working. Ignore the broken UTC date, having some issues with the time server. It allows GPIO control of a Pi Pico 2W thru a webserver, and that will eventually toggle on some small vent fans. It also reports the temperature and humidity. I could eventually add logic that turns on the fan based on the relative temperatures inside versus outside.
