BP; thanks for the update but then what is causing the lockup when the system boots with the am2315 attached (any i2c plug positon ) and it stops at "disabled Alexa..."? But when turned on w/o the am2315 attached, the system eventually starts scrolling input values from the sensors (including the ones not attached). If I "hot" connect the am2315 while it scrolls, it will on the next new pass, read am2315 data two times and then I get a dead display until I reboot. Allen.
Hello BP; Thanks for the AM2315, it is attached and seems to work; at least the boot up does not hang up on looking to connect to Alexa; allowing the system to sit around 10 min it will start polling the sensors and initially it is reasonable data but after several polls (I don't have time to hang around and watch it) the display will be -32F external and 0% humidity and I have to push the reset button and come back to check it again and it will start up ok but after a few hours I will check on it and its back to -32F and 0% humidity. I unplugged the adapter and reset the GPIO0 button; it was looking for my home wifi but I took the unit to my lab so I'm not letting it connect (although it is easy to talk to it on my Android smartphone directly and set the parameters for the wifi that way). After a while it will poll and readout but after several hours it is now reading reasonable humidity and external temperature but the inside temperature is -220F. After a few resets and poll cycles I see that it is reading inside temperature at -220F even if I aim a desk lamp (tungsten - so there is some heat) at it. Any trouble shooting directions would be helpful. Thanks, Allen.
Hello BP; So I reset the gpio and now it reads +32F for inside temp and 0 inches air pressure all the time. External temp and humidity are ok. Where on the board is the pressure sensor and thermal sensor? How do I get it to read correctly? Thanks, A.Lee.
