Frequently asked question

Does it work without a hub?

No, Its need to be with the hub

Es compatible con el sc 1000?

Lamentablemente no. Este sensor se comunica a 315 MHz y el sistema SC-1000 se comunica a 434 MHz. Usan protocolos muy diferentes.

Do you use the door sensor for windows too?

Yes, this may be used for doors or windows

Will this sound if glass is broken versus opening the window? Or should I attempt to buy another standalone product specifically for broken windows?

The WD-MT is a sensor for and requires the SK-150, SK-200, SK-250 or HU-100 and does not work on its own. The sensor works when the two pieces are separated, such as opening a door or window and not if a glass breaks.

    Great little system

    Have this system for my home. Full setup took 39 minutes for garage door, 5 doors/windows and a lamp. Incredibly simple. Let’s me know via my iPhone when any are opened. Went on a week vacation and didn’t have to worry someone was at the house. Bought a set for my son’s apartment too. Use removable “command” type tape for sensors and the whole system can move with you from place to place.

    Well-priced door sensors and system

    Works great. We’ve used these for over 2 years indoors and outdoors without replacing the batteries. We use these with the Skylink SK-150 Basic Starter Kit that has a hub and some Skylink cameras. When I bought the system in Oct 2015, this was the cheapest DIY system I could find. Some of the others had monthly fees or $30+ sensors (I paid $20/each for this sensor).
    For installation, the original sticky backs are strong. They stayed up about a year and then we had to pull some of them off when we were getting our door frames and fence replaced. To install the sensors again, we bought some double-sided sticky tape. We screwed one of the sensors to the door frame and that worked well too.
    The push notification is nice. If I’m at work and the notification goes, I can look on the cameras. The log of when the door sensors were triggered is handy too.

    Great, simple security system

    I LOVE this security system. First, there is NO monthly payment which means there is no ‘service’ to pay for. You get control of your system. Sometimes you just want the extra comfort to know you’re safe, even if you think your dogs *might* scare someone away. The system allows you to put these sensors on any door or window They are SUPER easy to install and set up with the app. Each sensor has double sided foam tape to adhere the sensors to the door frames (ours are 10 months old and they have stayed on) or you can screw them into the door frame. I prefer the foam tape so I don’t have to worry about holes. You can set up notifications on your phone for every time the door or window is opened/closed and then for other components that go with these sensors. The nice thing too is you can find a time stamped log of every time your door/window was opened and closed. You cannot use these sensors alone. You must get the hub for them to communicate to. The cost is reasonable enough for me to get sensors for all the exterior doors (we have multiple) and then purchase other extra components as well.

    Waste of Money

    I bought this for a second home. By the time I discovered that the sensor does not connect to the hub, the return window had closed. Overall, the SkyLink system has disappointed. It goes offline while we are away and you can’t get it to reconnect remotely. If you want a security system you can depend on, do not waste your money on SkyLink.

    Replaced Unit After 4 yrs 1.5 Mos - STILL 5 stars!!

    Had 1st unit in Heavy Duty Thick Walled Cast Aluminum Mailbox for 49.5 months (4 years, 1-1/2 months !!). Replaced it this month (January 2020) as it seemed to get ‘flaky’ – the range became shortened so i thought. Thus I bought a replacement then tested new vs old transmitters (part installed in mailbox) and their receivers (part installed indoors) and did a range test (distance). Repeatedly the original unit failed to receive a signal beyond 23 feet. Batteries were new Energizer – not lousy off brand junk. New unit passed with flying colors.
    Conclusion – suspect original transmitter suffered a degradation in ability to communicate. Stuff happens.
    Replacement unit working just fine. – life is good again!
    Now here’s the cool part …………
    I reprogrammed the original receiver to work in concert with the replacement mailbox transmitter (& new receiver) and positioned the old receiver FURTHER away in our kitchen. Yep, works great. BOTH units receive just fine and therefore provide great coverage within an 80 foot long home !!
    If you do not get one of these … keep trudging to your mailbox to see if (Ala Tom Hanks) … ‘You’ve got mail!’
