Cheapest / Best Motion Sensors & Door open/close?


(Morgan) #1

What is everyone using for cheap/good motion sensors? I have a bit of everything, and I like the ST ones but they are way too spendy.

Monoprice ones seem to have gone up, and I can’t find any of the PEQ ones anymore. What are people using for them?

Also, suggestions on good cheap open/close sensors, they seem to be more expensive than they use to be.

Best Sensor's for someone who is new to home automation (I am in US.)

Lowes Iris motion sensors and open/close sensors, especially when you can get them on sale (in store or online). If I had to do my doors and windows all over again, Iris would be my choice (sorry ST).

I tested 3 of the most popular Doors & Windoww, Open/close sensors:

  • Smartthings Multipurpose sensor
  • Iris 2nd Gen Contact Sensor (purple box)
  • Ecolink Door & Window Sensor

All 3 of them paired to my Smartthings hub without any issues.

The Smartthings is only 2 inch long, but is a little wider at almost 1 1/2 inch wide so it may not fit on all window frames.
It does report battery level and temperature.
I have 2 so far, and one of them stopped reporting. I had to remove the battery, unpair it, and re-pair with the hub to make it work again.
At $39.99, it is the most expensive of all 3 sensors.

The Iris is a good alternative.
At 2 1/2 inch long by 3/4 wide, it will fit on most doors and windows.
It reports both battery level and temperature.
And the best part: Price is only $22.99 at Lowe’s, but if you are lucky, you can find them on sale as low as $15.99.

The Ecolink does have a wire terminal for additional setups (like hooking up to your doorbell). It also comes with both white and brown covers to match different interiors.
But at almost 3 1/2 inch tall for an inch wide, it is the bulkiest of all 3.
However it has a strong construction feeling, with an added antenae.
It does report battery level, but no temperature.
I installed one under my bottom freezer door (with an alert if remains opened for over 1 minute) and I don’t have anything to complain about so far.
Price is $29.99
