Anyone hardwire the motion and/or multipurpose sensor? It’s unfortunate the new motion sensors lacks a USB port. I bought another house (2nd smartthings location) that is prewired for alarm (two wires) at each door/window and along the walls for motion. All wires go back to a centralized location t…

You can find project reports from people who have done this kind of project on the quick browse lists in the community – created wiki in the project report section under “power.” :sunglasses: http://thingsthataresmart.wiki/index.php?title=How_to_Quick_Browse_the_Community-Created_SmartApps_Forum_Se…

Existing hard wired alarm might be able to be modified to be seen by smartthings. As JD mentioned, take a look at the wiki. Here is an example of one that was done with an esp8266, which is very inexpensive. [image] Connect wired alarm system sensors to SmartThings with a NodeMCU …

The Aeotec multi sensor has a USB power option. [image] SmartThings. Add a little smartness to your things. Other than that, if you don’t want to solder you would have to look for a dummy battery option, but they aren’t usually made in that size.

Maybe you had more than one question. My last response was for connecting hard wired alarm to ST. As far as just a battery operated motion sensor, you could always just buy a 3.3v wall plug, cut the end off, and hook the wires to where the battery would normally go. I tape up the a dead battery to …

I am using this solution at my current house and it works great! But at my 2nd location, I would rather just use SmartThing’s sensors since they are the most reliable solution, at least in my experience.

In my experience the Aeotec sensors haven’t really been reliable and I had two that failed on me.

This looks great! Can you still put the cover back one? I suppose I could use a large power supply like this and connect all the sensors?? https://www.aliexpress.com/store/product/Factory-Sales-Power-Supplier-DC-3V-60A-180W-Switching-power-supply-For-LED-Light-Strip-Display/1260220_32281717528.html …

As long as your voltage is constant, around 3v, then I think that should work, but I can not confirm that. Yes the cover fits back on this one without any modifications. Doesn’t look great, but I’m sure I could get a better fit modifying it a bit with a drimmel, and have it come out the back. [im…

Instead of using the SmartThings wireless sensor, I would just get an inexpensive wired PIR motion sensor for about $20 and use my nodemcu-smartthings esp8266 project to hook it to SmartThings. You can power it with any 12V transformer. Much cheaper and you never have to worry about batteries.

Appreciate the response, this is the closest thing that I found: 3v Step Down Converters for Sensors

Any alternative to soldering?
