I have an Aeotec 6 sensor in my child’s nursery, and it is plugged in to USB for power. I originally got it to trigger on and off a space heater to keep the nursery a couple degrees warmer than the rest of the house. When I got it and set it up, I found that the shortest reporting time was several minutes, even though it is plugged in to USB. I did some searching on here, found a new Device Handler that allowed me to set the reporting period to whatever I wanted (now every 5 seconds). I then set up the Virtual Thermostat smartapp and it has worked perfectly since.
Recently, our child got sick, and I put asteam humidifier in the room to up the humidity in to help. I saw there was the “Smart Humidifier” SmartApp in SmartThings and quickly set it up. Except, it doesn’t work. It will trigger the humidifier to turn on the first time it drops below the threshold. But then it won’t turn off. I then have to manually turn off the smart plug, and then when it drops below that threshold again, it doesn’t turn on. I also noticed there were other SmartApps for controlling a space heater, and tried those as well and found I was having the same problem. Could this be because I changed the Device Handler for the sensor when I first got it?? I wouldn’t think so, seems to me the SmartApps are just looking at whatever value it is reporting. Does anyone have any suggestions?? Thanks very much to those that do!!
