Sensor range extender/booster/repeater

I completely agree!  I just replaced my SS Gen1 alarm with a Gen3.  I was told it was better.  It is certainly not better as far as distance from Entry points is concerned.  I do have a two floor larger home, but Gen. 1 did the job....not Gen. 3.  My Entry sensors keep dropping off at night (I think it is the cold, although I live in Calif.).

I have called support many times and get different skill levels each time...not good.  The last one was reading from a "sheet" to get me my answers but did not know how the system was supposed to work.  They have no "Level 2" support but will take the system back if within 60 days of starting it up.  I am on day 21.  I have moved my Base Station a number of times trying to get the system to work and still have one or two of the farthest sensors drop off each night.  It did not work at all in the spot I had my Gen. 1 base station for 10 years.

I am looking at a Ring alarm because they do have "Extenders" that will repeat the signals from Remote Sensors.  I believe it will be more expensive...but it will work.  If you have a big home, then do not try this system even though they will give you a refund.  The amount of time and frustration is too much.

Reminds me of the outdoor camera scenario.  Called SimpliSafe several times asking about the availability of outdoor cameras before they came out and nothing was revealed.  Meanwhile we went with another outdoor camera solution - - more expensive.  SimpliSafe please listen to your customers about range extenders and at least reveal if you're considering providing and/or selling them.

An older house with plaster walls may be part of the problem.

If the plaster is over wood lath, like my house, then no problem. We have devices everywhere, door bell & other sensors in the front and entry sensors in back. Also, we have smoke, CO and other sensors on all three floors.

If, however, the plaster is over expanded metal (~screening) lath then each room is isolated  from the others by  that lath. You've probably already had fun getting good WIFI coverage, let alone the lower frequencies  uses like SimpliSafe. 

I have been a monitored customer for the last 5-6 years and loved the system in the house. Unfortunately, as the back yard structures have multiplied (and have been broken into) I need to extend the monitored security out there. I tried moving some sensors around out there to test the feasibility but, even with them only 50ft out, the external walls are too much and it just doesn't work. I have waited about a year from my first inquiries to them with no updates, or new products announced. After all this time I have no choice but to go to the competitor that has a mesh systems with extenders, and costs more per month. Hopefully they can work out something for their other customers in the near future.

@BeachAndBoats1941 Thank you for this suggestion! This feature has been submitted to our dev team already, and once we get any news from them we will update the Community in this thread. 

The Base Station has a range of about 800ft in open air. In a home, physical and wireless interference can impact its signal. If your house has thick concrete or stone walls, or a heavy door leading to the garage, it can be a limiting factor depending on where the Base Station currently is. 

Even if you don't have a room that is directly in the middle of your home, I would try moving the Base Station a little closer to your garage to see if that helps your sensors connectivity. 

Agree that an extender for the sensors is very much needed. Ring has this feature, FYI.

add us to the list of those requesting an extender, please!

Hey all - I am the one selling the mod on Etsy. Please not I only make a few bucks per sensor so I do this more as a hobby then as a business 🤣

Here is the link for the pre-hacked sensor:

Also, for anyone that's curious about the range adding an antenna will add, I recently conducted some field tests with the antenna modification. See results below.

Hey man… firstly, thanks for the work, folks like you make all the difference. The lack of a way to boost or extend the base station seems insane to me! Why wouldn’t they solve it. Surely it can’t be that hard. Anyway, I have a couple of locks out of range so a) do you have an idea if extend their range is possible? Also.. I took apart the base station and found what I believe is the antenna inside. Wondering if there is a mod to that that might help? I’ve tried some crude stuff like tin foil etc.. but wondered if you had any thoughts?  

@gtalarico​ Wonderful product modification.  have you thought about doing similar modifcation to the Simplisafe Keypad?

Has anybody been able to successfully extend the range of the motion detector? I have been able to significantly extend the range of door sensors but extending/replacing the antenna on a motion detector doesn’t seem to help its very limited range. 

@ElusiveM​ There is a similar hack with a wire for RF range. If you're referring to PIR range, that has a device sensitivity setting and that's about it. Link below.

Per comments under the link it works.🤷

At your own risk of course.

@pearcenm  As I posted in the other thread, unfortunately a repeater for the SS3 will not help for your outdoor cameras. They connect via WIFI.  The OD cameras and doorbell pro in my 2600 sq ft 2 story home work fine but it take a bit of testing and reconfiguration of my Google WIFI mesh to accomplish that.  A call to Google 1 support did the trick, where the agent recommend that I take my 3 points (bought at costco years next to my router point after doing a factory reset. Then moved them back to their original positions and, after using the app "Netspot" found a location in our master bedroom almost directly in the middle of our 2 outdoor cameras, one in the back of the house facing due east and one in the front facing due west. Result: perfectly operating cameras, outdoor and doorbell pro.

Yes, I agree, upfront, a bit of work to get to this point but they have been working fine since I did it. As far as sensors, those in my basement, attached 2 car garage, 1st and 2nd floors, all 30+ of them are also doing fine. Please note I have vinyl siding and wood frame construction, no brick.

If you need assistance, try also calling support and send them your floor plan. I did that back in 2012 when I got my first SS2 system and their input greatly assist me placing my motion detectors, but that is a whole other story.

Hope some of this helps. To you and your family, a very happy holiday weekend

You can disassemble the sensor and attach a wire to the internal antenna, and have it exit a hole in the plastic casing that you drill.  The sensors all use 433.92 MHz transmitters, so you want a quarter wave long monopole type antenna which is a total wire length of 6.800 inches.  Be sure to include any of the internal wire antenna in the total length calculation.  For a more compact antenna you can use a loaded coil antenna or a helical coil antenna, however they will not have quite as much gain.
