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

Dont see the link?

There ya go Mohit.

That should help you weigh out everything before making a purchase in this new world. After you do your homework and narrow things down, I would then come back with those additional questions such as reliability and how a specific device or product works for people. You could easily just pick up the first device someone recommends, but the more you understand what it is you want to accomplish and do that due dilligence, you will be much more happy and satisfied in the end, knowing that you understand everything for yourself and that your purchase is the right one for you and less of a trial and error, because we have all been there.

Thanks @JDRoberts for taking the time. Hope you get to feeling better.

It was a small sample and it is a year old, but it did include the Smartthings sensor which I believe is zigbee. I any case, it is nearly impossible to give an definitive answer as to which sensor is best given each users individual needs and requirements.


Good point, actually thought you were referring to a different three sensor sample. My bad. :sunglasses:

This is very very true. That’s why to me, home automation is like going back to high school. You have to do your home work before trying to ace the test.

As you know, this is a frequent question. I recall a poll regarding these type of sensors was conducted once. Honestly, I don’t know how you remember all the past posts the way you do. We are all lucky for the assistance you provide. Hope you feel better soon.

I don’t have a perfect photographic memory (my sister nearly does), but I do mostly remember what I read. So it’s pretty easy for me, especially if things are filed in the right categories so I can find them again.

As for getting better, that’s not really the way it works. I have good days and bad days, pretty much at random. I appreciate the thought in any case. :sunglasses:

For me personally, I take “cheap” and “budget” out of the equation when choosing a specific device. “Cheap” doesn’t always mean flaky and unreliable, but from my experience, you get what you pay for, more times than not. If something is too expensive, I would rather be without the technology for the time being, instead of purchasing something that wasn’t up to par just because it was more affordable than the proven more expensive model to come home later and find out that it doesn’t work, broke, went offline, batteries drained in a day, etc. etc. Sometimes going without it is so much better than the pain that comes with something that doesn’t work the way you expected it to no matter what you paid for it.

This of course is only one thing that I factor in when making a decision for my smart home and it’s not always/only about the price. You will find things that everyone touts and raves about, only to find out that in your environment it didn’t have the same positive results. Some of this is going to be trial and error, as it can be a double edged sword. The best advice I can give before moving forward is that you do your own due diligence and homework and not rely on a single review or post and weigh out all pros and cons and try and mitigate those trial and error situations to a much smaller subset. And if unsure, ask ask ask questions. As you can see from your post today, plenty of people are here to offer their thoughts, suggestions, recommendations.


This ^^^

I’ve got about 8 or so of the Visonic sensors around the house, and they are reliable, easy to pair (native smartthings support), run locally, and except for one at the farthest point in my house (where to be fair, other Zigbee sensors also did not work) have worked w/out issue. They use the CR-2032 battery, easy to find and it’s a 10 second job to slip in a new battery.

One the best benefits is that they are a lot “sleeker” and less obtrusive than other door/window sensors, which makes them easier to fit into tight spaces (less likely to get bumped by blinds/shades/people), helps w/the WAF and generally looks less tacky than the larger rectangular sensors stuck all over your windows and doors.

If you miss the sale on Amazon, you can also get them at the site below with discounts for quantity…I’ve ordered from them a few times, no issues. If you need more than 10 that’s down to $15.99 each.

$17.99 each
Qty Price
2-9 $16.99
10-99 $15.99
100+ $14.99

For door sensors at the farthest point (including outside shed) in my home I’ve had to use Zwave/Zwave Plus sensors. I don’t have a Zigbee repeater and my Zigbee network isn’t as strong as my Zwave. I have Zwave light switches and Zwave plus door sensors that extend the Zwave network so I have better reach at extreme locations via Zwave.

I’ve gotten a couple of these Zwave Plus and they have had zero issues.

Motions and Contacts in every room that you want to automate and maybe even multiple motions.
Humidity Sensor in Bathrooms with exhaust fans.

IMHO the SmartThings Multi-Sensor is a horrible multi-sensor. There are soooooooo many issues with these things. I’ve replaced 8 in less than a year.

I have about 200 devices and I’ve tried many many many many sensors. Here’s my suggestions:

Lowe’s Iris Motion run locally and you can find them sometimes for $14.99 when they go on sale for buy 2 get 1 free or 33% off and sometimes combined. Also there are the Lowe’s coupons that you can generate to knock even more off the price. They are damn near instant and only have a 30 second re-trigger time.

Ecolink Motion. Runs in cloud, super fast, pet immune, super reliable but has a 4 minute re-trigger time.

Lowe’s Iris Contacts run local, relatively inexpensive, batteries last a long time and are damn near instant.

Visonic Contact Sensors run local, relatively inexpensive, batteries last a long time and are damn near instant.

Xoami are fussy to get paired and sometimes drop off but they are the ones to get if you are going the cheap route.

I don’t have a solid recommendation for humidity sensors. I use the Zooz multi for humidity only as the motion is not fast enough for my taste. If using Zooz, it is almost necessary to hard-wire as battery life sux donkey butt.

I see that you joined on January 9 and posted the following:

And then your new thread today:

Sorry, it just struck me as odd “new to home automation” after almost a year. Oh well, hope he got what he was looking for from everyone.


I disagree.

Theoretically that should be true, since ST has certified that those devices will work with your hub, and you can even get support to help you out if it doesn’t (they may or may not help if you’re using unofficially supported devices).

In reality, many people find the ST branded devices to be very unreliable and a total headache to use.

@WB70 I have those devices but i never ventured into motion sensors and other sensors, i am looking to start but i wanted to get inputs on what start with that’s all.

Just a small datapoint - I recently replaced all (maybe 5) SmartThings multipurpose sensors because (to me) they were unreliable.

I replaced them with about 12 of the Visonic sensors mentioned above from mydigitaldiscount. Most of them cost me $10, the last few cost more (price went up as demand went up). I got an email yesterday from camelcamelcamel that Amazon currently has them for $14.99.

Thanks for the clarification Mo.

It was all about the wording. Making sure that there was no ulterior motive.

Happy hunting with the sensors :slight_smile:

Thanks for the feedback @rontalley! We’re working on a new version of the sensor with both motion detection and battery life optimized. It should be available in early December.

We’ll also be changing battery to CR123 to improve overall battery life - that version should arrive in January. Feel free to contact our support if you’d like us to send you a sample for testing once the sensor is ready:


Now that Iris is shut down, what’s the best recommendation for motion sensor.

You can still find the Iris’s on FleaBay (EBay)but as always, you run the risk of someone selling you a defective device.

The Ecolinks are SUPER reliable and the batteries last forever. However, they are rather big and only update every 4 minutes. I use to think that that was an issue but most of my automations are at least 5 minutes of inactivity before something turns off…

The most comparable to size, battery life, function and reliability is actually the newer Samsung Motions…I only have a couple and they haven’t given me any issues.

The most affordable is the Xiaomi motion. However they are hard to pair and reliability is an issue sometimes. Once I got them paired and let them sit by the Hub for 24 hrs, they’ve been rock solid.

thank you for the quick reply!

I have used only SmartThings sensors in the past and have no issues with them. I had narrowed it down to the tall ecolink, Samsung v2, and zooz 4in1. I think I’ll go with more Samsungs.
