Extended Range Simplisafe Entry Sensor

Product Description

These are original Simplisafe Entry Sensors (SS2) modified with an antenna for extended range. The actual sensor retails for $15 without the extension.

You can use the modified sensors for locations that are too far from the base to pair, or that pair but frequently disconnect.

The original sensor is advertised as 800 ft “open air” range, this is slightly misleading –
depending on the building configuration and materials, the existing antenna can fail to provide a stable connection for much shorter distances.

I cannot guarantee the antenna will extend the range enough for your particular situation, but I have verified in my home I get 2-3x the distance when compared to a regular sensor. If the extended range is still not enough for your particular case, I am happy to accept returns minus shipping costs, provided the item is in the same condition as received.

** Testing & QA**
Each sensor goes through a quality check where I pair and verify their range.
In one of the attached images, you can see the testing location. The regular sensor loses connection about 98ft from the base. I check each sensor reports open/closed status from an additional 150ft up my street.

** Sourcing **
The sensors are purchased new from Amazon and and modified by me.
They have never been used and are only handled for the purposes of adding the extended range antenna and testing. The original packaging, tape, and screws are included.

** Compatibility **
This entry sensor is for Gen 3 Simplisafe only.

** Antenna Length **
Sensors will ship with an antenna measuring approx. 11.5″
You can cut that in half for a shorter antenna, although this may lower the range very slightly.

** Antenna Direction **
The default mod has the antenna hole near the setup button (down). We also offer a variant where the hole is on the opposite side of the button (top). There is no performance different, you can chose one or the other based on how you have your sensor installed, and how you want to run the antenna cable. Please note the “top” variant has an extra cost since I make those on-demand for each order.

** Disclaimer **
Please note this modification will void the manufacturer’s sensor warranty. However, I do test each sensor individually before shipping them.
If you have any issues setting up the sensor, feel free to send me a message and I can try to help.
