Review: Works great for my Z wave HomeSeer system - I use it in the freezer with a cable connected to it for power. I have several and they all work great.
Review: False alarms - This is on my dehumidifier in a usually dark basement affixed over the blinking full light. With the unit plugged in I was initially getting many false alarms, so many that I was going to return it. I removed the device from the Z-Wave controller and re-added it. That took care of most of the false alarms. It turns out that the light sensor sees the basement lights when they turn on, even when the unit's sensitivity is set to low. This triggers a false alarm. And, yes, I made sure the sensor was firmly attached and that there were no gaps around its edges. The lights in my basement are bright so I surmise that the plastic covering the sensor is too translucent. I put black tape over the top of the sensor and the false alarms have stopped completely. I'm happy with the way the sensor works now, but having to put black tape on it to make it reliable is awful.
