TOPGREENERPIR Motion Sensor Light Switch, Occupancy & Vacancy Motion Sensor Switch, 𝐎𝐩𝐞𝐫𝐚𝐛𝐥𝐞 𝐖𝐢𝐭𝐡𝐨𝐮𝐭 𝐆𝐫𝐨𝐮𝐧𝐝 𝐖𝐢𝐫𝐞, No Neutral Wire, Single Pole, TDOS5-HL-W-2PCS, White

This is THE answer to no ground AND no neutral wires in a light switch box. And while installation instructions do ask for hot and load wires to be attached to specific labeled connectors on the switch, a fine reading of the diagrams indicates that the switch works with these wires reversed. So its pretty much fool proof. Words and diagrams in the instructions are clear. Good adjustment settings for sensitivity and how long the light stays on when motion is not sensed. I bought two of these for the price of one switch by a major name which said "installs with your existing wiring," but that means your existing wiring MUST have at least a neutral or a ground wire. BTW, do "shut off the power" before removing and installing a switch. So find the right circuit breaker to trip, and use a power sniffer as a double check. You owe it to yourself and your loved ones to not risk injury or death when working with such things.

I have many PIR-controlled lights in my house, ceiling lights, portable LED lights, Lutron/Leviton bathroom switches. Unfortunately, all of them have one annoying feature:"Light Switch will turn off the light after the set time elapses, even if motion is continuously detected."What I wanted is to have a switch with truly "occupancy sensor" mode, when the switch is ON while you are in the room. The TOPGREENER TDOS5-HL device perfectly does this: the time-out timer apparently gets reset every time the motion is detected, so it won't make you panic and convulsively wave your arms . It looks like the small front LED flashes every time it detects a motion, which is a very handy feature. It will, however, turn the load off if you keep being motionless for the entire time-out duration, which is difficult to do for 5-10 minutes.Among other pluses I would mention that the device configuration uses analog trimpots. They are not as accurate as digital controls, but who cares if the delay is 20 or 22 minutes? The advantage is that if you have a power interruption, you don't need to re-program all your switches while digital switches will reset to defaults.The sensitivity is more than good for a bathroom or laundry room. My load is a 80CFM exhaust fan and a light fixture with 3 bright LED bulbs.I didn't try it for larger spaces as a garage. The description claims 1200ft coverage. This means the distance of ~34ft, while the max setup on internal dial says 4 ft, which is contradictory. It looks unlikely that the switch will work in every corner of a 1200 sq.ft space, and some people are complaining here about intermittent functionality even at 10ft.Overall, the TOPGREENER TDOS5-HL switch is an excellent product, clear 5 stars.

I tried this in three places... in the basement, in the garage, and in the laundry "nook".It works very well in the laundry nook, because you are right near the sensor when you are working in the area, so it stays on.In the garage, i cranked the range all the way to max, but it struggles to know i am there in most parts of the garage. It seems like there is about a 10' range in front of the sensor, and if you are outside of that, you get stuck in the dark. Same in the basement.You can work around this a little by increasing the timer, so it stays on for 10-15 minutes, because you are more likely to trigger the sensor again in that time frame and re-set the timer, but the tradeoff is that you are wasting more energy. I prefer to set the timer as low as possible, so the light turns off fairly quickly after you leave the room.Going back to the garage example... part of the reason I use a motion sensor in the garage is that i am constantly in and out of there grabbing tools, etc, and am likely to leave the light on when i leave. If I can use a motion sensor that triggers easily and set the time low... like a minute or less, then i can pop in and out of the garage all i want and not worry about leaving the light on. But if i set the time higher to compensate for the lack of range, then i am leaving the light on for 10-15 minutes every time i go in and out of the garage.So as you can see, i have pretty specific wants/needs for my use case, but i can see these working very well for people in a lot of situations... Hopefully this helps you adjust your expectations and/or make an informed decision about this product.

Better than a smart switch in specific applications. For a dark stairway to the basement, open the door and the light comes on. I left it on "test", so the light goes off after about 15-30 seconds, but stays on as long as motion is detected. But the other of the 2 pack in another basement room with a freezer and dry goods storage, another excellent place for a switch like this. Both installs only had a hot wire loop through the switch, so not needing a neutral wire to work was critical. Installation was quick and painless, and I don't have to tell Alexa to turn light on, and then off. First world problem I know, but worth the $ and little bit of time to have things just right.
