I’ve been using this DH with the Monoprice device for a few weeks and had some observations I wanted to share.
First, it is located nestled between the ceiling and wall above the entry door to my bathroom. I have a Lutron caseta dimmer switch for the lights and a GE z wave switch for the bathroom exhaust fan. Part one is I use the humidity sensor to turn on and off the exhaust fan automatically (though I feel like I need to have a second one for manual usage and auto shut off after x minutes).
Part two is for a night light. At first I had setup the sensor to use it’s light monitor and if it sensed motion while under a certain light level to kick on… that didn’t work very well as the light sensor is erratic. During daylight hours (there are two windows in the bathrooms which shades always closed but enough ambient light) it would still read a 0 or 1 lux. It would kick up when the lights went on but may not kick down for awhile (or ever it seems sometimes).
So I just went to if ST mode is night and there is motion then have a night light on for 1 minute or as long as the motion stays on. I have motion sensitivity to 1. The problem is that sometimes it takes quite a few seconds to sense motion. And the battery is already at 70% and I’ve only had the thing for a month. I don’t know if that is just the nature of a battery operated sensor or (as mentioned above) the need for a monoprice specific DH. Just thought I’d mention it.
Perhaps I should have gone for the Aotec sensor for a bit more and plugged it in. My concern is hiding the wires (possible though) and if I lower the sensor a few feet from the ceiling (to hide the wires) will the humidity sensor still kick the fan on quick enough and stay on long enough. I’m going to do a similar setup in a spare bath (I installed the exhaust recently because the jerks didn’t put them in the two full baths since they had windows) soon so I could just move this sensor into there were hiding wires, and thus going wired, may not be an option.
At the very least it works pretty well so thanks RBoy!
