For example, I place the mcModule120 in a closed drawer in complete darkness. It works fine for a few hours then every 30 minutes of so I get messages that the light sensor was triggered even through the drawer was never exposed to light. I noticed the same behavior on the reed switch. Any suggestions as to why? Any suggestions on how to resolve this? #Post#: 2209-------------------------------------------------- Re: Light Sensor Demo By: mc-Josh Date: January 3, 2018, 2:13 pm --------------------------------------------------------- Post the code and we can take a look. What is the state of the battery? Is it a fresh battery or has it been in use for some time? *****************************************************
