I need a garage door sensor that sends push notifications to my phone when left open.

Yes — what you want is a smart garage-door controller with a door-position sensor, rather than just a basic alarm sensor. It can notify your phone when the door opens and, ideally, remind you if it stays open.

$67.99

Chamberlain myQ Smart Garage Control

$29.99

YoLink Smart Garage Door Sensor

$31.74

Genie Aladdin Connect

$49.99

1. Meross MSG200HK — my pick for most people

• About $68 currently
• Sends phone notifications when the door changes state.
• Can control the door remotely.
• Supports Apple Home/HomeKit, Alexa, Google Home and SmartThings.
• No monthly fee.
• Can handle up to three garage doors.

2. Chamberlain myQ — simplest

• Around $30.
• Includes the Wi-Fi hub and door sensor.
• Lets you see whether the garage is open and receive app alerts.
• Particularly attractive if you already have a Chamberlain/LiftMaster opener.
• One caveat: myQ's ecosystem/integration policies have become more restrictive, so I prefer Meross if you're building a broader smart home.

3. YoLink — best if you ONLY want monitoring

YoLink Smart Garage Door Sensor

$31.74

This is particularly interesting for your exact request: the sensor can send push notifications, email, and text messages, and has an "open reminder" feature. It does require a YoLink hub.

What I'd buy

If you want "Hey, I left the garage open — tell my phone", I'd get the Meross MSG200HK if you also want the ability to close it remotely.

If you only want an alert and don't care about remotely opening/closing the door, I'd go with YoLink.

If you tell me what garage-door opener you have (Chamberlain, LiftMaster, Genie, Craftsman, etc.) and whether you use iPhone or Android, I can narrow it down to the exact compatible model.

Finding a reliable smart garage door sensor that pushes alerts right to your phone is a game-changer for peace of mind. Here are the top recommendations categorized by ecosystem and ease of use:

• Best For: Most standard garage doors (compatible with most openers made after 1993).

• Features: Sends real-time open/closed status alerts and lets you close the door remotely via the MyQ app. Note: Check current app integration updates, as third-party smart home integrations (like Alexa or Google Home) may require subscription features depending on your setup. You can check details or purchase on the Chamberlain myQ Official Site.

• Best For: Apple HomeKit users, as well as Alexa and Google Assistant.

• Features: Highly rated, affordable, and integrates natively with Apple Home, allowing you to set time-based reminders (e.g., "If door is open for 15 minutes, notify me") and trigger Siri voice commands. Available to view on the Meross Official Site.

• Best For: Existing Ring security system owners.

• Features: Seamlessly integrates into the Ring ecosystem to send push notifications to your mobile device if the door status changes or is left open too long. Requires a Ring Alarm base station. Explore options at Ring.

• Best For: Smart home enthusiasts using a local hub like Home Assistant, Hubitat, or SmartThings.

• Features: A dedicated tilt sensor meant specifically for garage doors that communicates via Z-Wave. Highly customizable notifications through your home automation hub without reliance on proprietary cloud apps.

To help me narrow down the best exact fit , could you tell me:

• What smart home ecosystem do you use (Apple Home, Alexa, Google Home, or Home Assistant)?
• What brand is your garage door opener?

Yes. What you want is a smart garage-door sensor/controller with “open too long” alerts. You don't necessarily need to replace your garage-door opener.

My top picks

YoLink Smart Garage Door Kit

$45.99

1. YoLink Smart Garage Door Kit — best if you only care about alerts

• Monitors whether the door is open or closed.
• Sends push notifications, email, or SMS.
• Has an Open Reminder that can alert you after a set period—20 seconds to 2 hours.
• Very long wireless range, which is useful if your garage is far from your router.
• The kit includes the sensor and controller.

Meross Smart Garage Door Opener

$49.99

2. Meross — best if you want phone control + smart-home integration

• Sends smartphone notifications when the door opens/closes and can send overtime/overnight reminders.
• Works with Apple HomeKit, Alexa, and Google Assistant.
• No subscription fee according to Meross.
• Particularly attractive if you use an iPhone/HomeKit.

Chamberlain myQ Smart Garage Control

$29.98

3. Chamberlain myQ — easiest if you have a compatible Chamberlain/LiftMaster opener

• Gives you garage status and phone notifications.
• You can configure alerts/reminders for an open door. Chamberlain says most notifications arrive within about 90 seconds, though timing can vary.
• Important: newer Chamberlain Security+ 3.0 openers have significantly restricted compatibility with third-party controllers, so I'd check your opener model before buying Meross/other alternatives.

What I'd buy

If your primary requirement is simply “Tell me on my phone if I left the garage open”, I'd lean toward YoLink. If you also want to open/close the garage from your phone and integrate it with Apple Home/Alexa/Google, I'd lean Meross.

If you tell me the brand/model of your garage-door opener (e.g., Chamberlain, LiftMaster, Genie, Craftsman) and whether you use iPhone or Android, I can tell you exactly which one is compatible and find the best current price.

To get push notifications when your garage door is left open, you need a smart garage controller with an open/close sensor (or a standalone smart contact/tilt sensor). Depending on whether you want a complete retrofit kit that also lets you open and close the door from your phone, or just a simple monitor, here are the top options:

2. What garage opener brand/model do you have? (Chamberlain/LiftMaster, Genie, Craftsman, etc.)
3. Is your garage within Wi-Fi range? If not, a long-range system like YoLink may be a better fit.

If you tell me your garage door opener brand/model and whether you use iPhone or Android, I can narrow it down to the best compatible choice.

The [YoLink Smart Garage Door Sensor Go to product viewer dialog for this item. ](https://shop.yosmart.com/products/ys7706?currency=USD&variant=44789845917947&utm_source=google&utm_medium=cpc&utm_campaign=Google%20Shopping&stkn=6defc0084190&srsltid=AfmBOorMz2qMWWE7MU-cw8F10fws3j_l3Ou2E2scfATprkTln_MA2KAOIn8) is an affordable, highly reliable option that costs around $25 and explicitly features door left-open reminders with direct push notifications to your smartphone.

Top Garage Door Sensor & Controller Options

What to Consider Before Buying

• Hub vs. Direct Wi-Fi: Standalone Wi-Fi sensors connect directly to your router, but detached garages often suffer from poor signal strength. Hub-based systems (like YoLink) use dedicated sub-1GHz radio frequencies that maintain a rock-solid connection over much greater distances.
• Notifications vs. Control: Simple magnetic tilt sensors only tell you if the door is open or closed. Smart garage controllers (like Meross or Genie) actually let you tap your phone app to close the door remotely when you receive an alert that it was left open.
• Ecosystem Compatibility: Check if you want integration with smart home platforms like Amazon Alexa, Google Assistant, Apple HomeKit , or Home Assistant so your alerts can trigger routines or voice announcements.

If you let me know your preferred smart home ecosystem (Alexa, Apple Home, Google Home, or standalone app) and whether you want to just get notified or also close the door from your phone , I can narrow down the exact recommendation for you.

To get push notifications when your garage door is left open, you have a few solid hardware options depending on whether you just want a monitor/sensor or a full smart controller that can also close the door remotely.

Top Recommended Options

• Type: Dedicated position/tilt sensor (requires the YoLink Hub).

• Why it’s great: It uses LoRa wireless technology, meaning it has an incredible range (up to a quarter-mile) and easily punches through thick garage walls or outbuildings where standard Wi-Fi fails. You can set custom "left open too long" durations and times via the app to trigger push notifications.

• Where to buy: Find it directly via the YoLink Store or check availability on The Home Depot.

• Type: Smart controller with an included magnetic/tilt sensor.

• Why it’s great: Highly rated by testing platforms like The New York Times Wirecutter Best Smart Garage Door Controller Review , Tailwind not only notifies you when the door is left open, but it can also be configured to automatically close the garage door after you leave or after a set time.

• Where to buy: Available on the Tailwind Official Site or Tailwind iQ3 on Amazon.

• Type: Universal retrofit Wi-Fi hub and sensor.
• Why it’s great: It adds smartphone control and monitoring to most standard garage door openers manufactured after 1993. Using the companion app, you can easily program alerts to notify your phone if the door stays open past a specific timeframe.
• Where to buy: Check options on Best Buy or major hardware retailers.

To help me narrow down the best exact fit for you, let me know:

• Do you just want an alert/reminder , or do you want the ability to close the door remotely from your phone?
• Do you already use a smart home ecosystem like Apple HomeKit, Amazon Alexa, or Google Home?

If all you want is a push notification when the garage door is left open, you don't need a full security system. A smart garage door controller or dedicated garage door sensor is the easiest solution.
