  • INSTEON Open/Close Sensor is a magnetic contact sensor that wirelessly controls lights and appliances throughout your house. When magnetic contact is broken, such as a door or window being opened, Open/Close Sensor can do things like turn on lights, set the thermostat to its comfort setting, or receive text message alert on your smartphone (requires INSTEON Hub). Gain the peace of mind knowing that you'll be alerted when the back door sneaks ajar or the side window slides open. Useful for doors, windows, drawers, sheds, cabinets, and anything else that opens, Open/Close Sensor is a wireless, easy-to-use solution for adding convenience and awareness to any INSTEON-controlled home. An AA battery is required and included. TriggerLinc controlling lights

    How it works In the example illustration above, Open/Close Sensor is mounted to a door frame and the included magnet attaches to the door. When the magnet is separated from Open/Close Sensor (door opening) it sends a wireless RF signal to the nearest Access Point or other dual-band product (sold separately) which in turn relays the signal over your existing power wires to turn on linked devices such as lamps or wall switches. When the door is closed, Open/Close Sensor turns those same devices off. While at least 1 dual-band product is required when using an RF transmitter, at least 2 are recommended to ensure a reliable INSTEON network. Please note that INSTEON Wireless Open/Close Sensor (2843-222) is the new product name and number of TriggerLinc (2421). The product and functionality are the same. Required Accessories For the best INSTEON network performance, be sure you have properly installed at least two Access Point or other dual-band product.

    How it Works Simply install a battery, adjust the settings (jumper) based on your application, link Open/Close Sensor to other device(s) on your INSTEON network, and then it is ready for mounting. Open/Close Sensor has been pre-configured (default setting) to turn on a light (or other INSTEON controlled device) when your door is opened (magnetic contact is open) and off when the door is closed (magnetic contact is closed). This default setting is great for doors, windows, garage doors, sheds or closets where you want the lights to turn on when the door is opened and you can be sure the lights are off when the door is closed. Open/Close Sensor's second setting allows for a more custom type of control: Turn on (or off) one set of lights or devices when the door is opened and turn on (or off) another set of devices when the door is closed. For example, this feature provides uses such as:
    • Have lights turn on when you open the door, but leave them on when you close it
    • Have lights turn on to full bright when you open the door, and dim them to 50% when the door is closed
    • Plus many more INSTEON Open/Close Sensor also contains an input for standard security sensors, so you can monitor many doors / windows from a single Open/Close Sensor.

    Great Door sensor, but try the hidden door sensor first. No low battery for this unit.

    Easily installed, just think through the location beforehand. Orientation of the magnet isn't as critical as might be expected: I have two where the window/door type dictated rotating the magnet by 90 degrees on the long axis to make installation possible. Just test fit until you're sure the mounting positions will function reliably before attaching permanently. Functions properly and is supported via UDI's ISY series controllers. I gave four stars only because I don't know battery life, yet.

    Review of 2843-222

    generally working fine, but I cannot get one of them to stop sending alerts. I cleared out the phone number but I still get a text alert. Also the range seems to be an issue and I have a hub and extender.

    Easy to mount and easy to program, but you do need an "access point". Fortunately I already have a number of them in my system

    Turns on my shed lights automatically when I open my door. and acts like a alarm and notifies me of entry. Great when I'm away.

    Review of 2843-222

    great product. Works well. Could be smaller. Installation is very easy using included double sided tape. If you need to catch exact closed position you might want to put magnet a bit apart from the sensor. Just find a point of triggering by moving magnet closer and away from the sensor.

    Works really well stock. I modified it to text and email me when my house alarm goes off. That also works really well.
    Thank you,
