Entry sensor fell off door and will no longer stick for more than a few minutes.

One of the pieces of our front door sensor fell off the front door this evening setting off the open door bleep.  Fortunately, we did not have the alarm on and we will not arm it tonight.  Apparently, the command strip glue did not hold because the front door was quite cold (3 F outside).  We will not use screws to attach the sensor because it is a fiberglass door.  Can you provide a solution?  Perhaps a stronger command strip?   BTW:  I called SimpliSafe and was forwarded to a customer service support person who was awkward in her communication and didn't seem to have a suggestion, so I'm asking here.

I live in California, so beyond my winter home up north, the temperatures never get as cold as your case. But perhaps using a space heater or hair dryer to warm the door/area before attachment might help? It is only a quick guess to a solution, and perhaps someone who resides in colder weather will provide a better answer. The only time something falls (due to cold temperatures) where I live is my dashcam.

Ensure you properly prep the surface by cleaning it first (preferably with rubbing alcohol) and pressing the sensor to the prepared surface for at least 30 seconds. Also, make sure they are indeed 3M strips. I know it may seem unnecessary, but the company was shipping an off-brand adhesive strip with the new systems and components. I do not know if that is still the case. The ones that came with my second system in 2018 were from a company I never heard of, and I did have a Keypad and Motion Sensor fall as a result. It was not until I replaced them with 3M Command strips that I no longer worried (and I have not one screw attached to any of my sensors or components).

Thanks   The sensor has been attached for months and did make it through colder nights.   I suspect the adhesive dried out.

No problem.

I realized I never knew the temperature range of 3M Command strips. After a Google search, I found an answer from the Command site that also might be of help:


Climate and Temperature

Can I use Command‚Ñ¢ Products outside in cold climates?

Yes you can with Command™ Outdoor Products. The adhesive should be applied to a clean, smooth, dry surface when the temperature is above 15°F (-9°C). The products hold strongly down to -20°F (-29°C).

Thanks again.  I just ordered the outside, small, replacement Command strips.

Clear "Nano" tape is the best solution, I think.  It's super-sticky but still removable.  It will not fall off.
