I followed the instructions, and on the map it shows as responding, but there are no readings for humidity, temperature, or PM 2.5. No values at all except the last update.
Not sure what to do at this point.
Okay, took it apart again, and reseated all the cables. Now it comes up with values. Getting those connectors into the sensors required more force than I had originally thought.
Great that it works now. I will mention it in the build instructions next time I update it.
