Okay so I have ordered a lot of 10 Iris 2nd gen motion / temp sesnors from an Ebay seller (price was right, I have LOTS of CR2 batteries waiting to be used, good mix for me!).
So let’s look at the lighting issues.
Master bath.
I want the lights to come on with sensing motion, whether on the toilet, or in the shower. I thus far have been succesful in doing this with a single ceiling mounted ADT SmartThings dual branded sensor.
Master vanity / changing room. This is a funny shaped room. Picture a hallway with a long vanity and mirror on one side, and then a bump out room canted at a 45 degree angle, so if you drew it out, the room would look like a kids drawing of a house with 2 sinks at the bottom. The entry and shower / commode door would be on what in the drawing would be the 2nd floor. I am planning on making a wedge mount and moving the ADT ST dual branded sensor HERE, and using it to turn on / off the light for both the vanity, AND the dressing room. HOWEVER…
I need to figure out a way to detect only HUMAN sized motion. I don’t want the motion of the ceiling fan, or the cat to turn my lights on.
That puts me back in the bathroom / shower / commode area. THis is where one of the Iris 2nd gen sensors will go, just a one for one swap. Is there a way I can use the temp sensor to keep the lights on with this? That way I don’t have to keep it mounted to the ceiling?
Front hallway. This one is tricky. The hallway is a long hall, with more of those funny 45 degree angles. I want to trigger the light when someone approaches the hallway, however there are 4 accesses to this hallway. in sort of a bent cross shape. Front door, to living room is one line, front bedroom to kitchen is the second line that is bent…
Main / Guest vanity. Just a hallway, no bump out. an entry door on each end. The idea here is to use the Iris sensors on each end pointed at the other door to catch any motion and turn the light on.
Main / Guest bath / commode. Same arrangmenent and question as master bath. Can I use the temp sensor to keep the light on? Let’s say ambient temp in the house is normally 74 deg F, and the temp runs up to 80 in this one room and the light is on, keep it on until the temp drops to 74 or 75…
That uses 4+ of the Iris sensors.
The laundry room is already configured with my pre existing Iris 2nd generation motion sensor. Senses motion, light comes on, motion stops for 1 minute, light goes out…
Living room is a great room that is oddly angled. A box with another box on it at 45 degrees again, that blends into the hallway. I want to trigger the lights with motion, if the lights are off, and turn lights off with no motion after XYZ time, This room I want to get a Zooz 4 in 1 sensor as I want to measure RH as well to run a dehumidifier. The temp isn’t my biggest concern so much as is humidity…
Dining room, just a box, but it is open concept to the kitchen and living room. Not sure how to control that light…
Kitchen. Again, open to the hallway and dining room…
Master bedroom, other bedrooms, don’t want motion activated lighting at least for now. However the master, another Zooz 4 in 1, and another dehumidifier will go a long way to keeping my home comfortable for a LOT less money…
