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

To get push notifications on your phone when your garage door is left open, you generally have two routes: a dedicated smart garage controller with an included position sensor (which lets you both monitor and open/close the door from your phone) or a standalone wireless tilt/contact sensor tied into a smart home hub.

The top options for reliable open-door push notifications include:

One of the most popular standalone retrofit devices. It connects to your existing opener motor and uses a wired/wireless sensor to track if the door is open or closed. The Meross app sends direct push notifications if the door is left open for a specific duration or at a set time of night. It also integrates smoothly with Apple HomeKit, Amazon Alexa, and Google Assistant.

Renowned for ultra-reliable tracking and automated features. It comes with a heavy-duty door sensor and features automated night-closing or departure/arrival triggers that notify you or automatically shut the door if it's left open.

If you already run an Abode security system (or want a standalone ecosystem sensor), this battery-powered tilt sensor mounts directly to the top panel of the garage door. It communicates status changes directly to your phone via the Abode app, alerting you the moment the tilt changes (i.e., when the door opens or remains open).

If you'd like to narrow this down, let me know:

• Do you want the ability to open and close the door from your phone, or just monitor/get alerts?
• Do you use a specific smart home ecosystem (like Apple HomeKit, Google Home, Alexa, or SmartThings)?

If your main goal is “tell me on my phone if I accidentally leave the garage door open,” I’d get a smart garage-door controller with a door-position sensor, rather than a basic contact sensor. That gives you push notifications and usually lets you close the door remotely too.

My top picks

• Meross MSG100 Smart Garage Door Opener - $50.99 (Meross Official Store)

Best overall: Meross MSG100 — about $51 currently. It retrofits onto your existing opener, provides phone alerts/status, and doesn't require a monthly subscription. It also works with Apple Home, Alexa, Google Home and SmartThings.

• Chamberlain myQ Smart Garage Control - $29.98 (Walmart)

Simplest: Chamberlain myQ — about $30. It includes the garage-door sensor and sends real-time notifications through the myQ app. It's particularly worth considering if you have a Chamberlain/LiftMaster/Craftsman opener.

• YoLink Garage Door Kit - $45.99 (YoLink)

Best if Wi-Fi is weak in your garage: YoLink — the sensor uses YoLink's long-range radio and can send app push notifications, email, or text alerts. It requires a YoLink hub.

What I'd buy

Meross MSG100 if you want the best combination of price + notifications + no subscription + smart-home compatibility.

One important distinction: if you only want a notification and don't care about opening/closing the door from your phone, I can also find you a cheaper standalone garage-door tilt sensor.

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 narrow it down to the exact one that will work.

To get push notifications on your phone when your garage door is left open, you generally want a smart garage door controller/sensor kit . These systems attach to your existing garage door opener, use a sensor to detect if the door is open or closed, and push alerts straight to your phone via an app.

The top options on the market depend on your smart home ecosystem and preferences:

This is widely considered one of the best retrofit choices. It features a high-sensitivity sensor, works with Apple HomeKit, Amazon Alexa, and Google Assistant, and has no monthly subscription fees . Its app specifically allows for "overtime notifications" and "overnight notifications" to alert you if the door has been left open for a specific length of time.

A very popular wireless hub-and-sensor option that works with most major garage door brands manufactured after 1993. The myQ App lets you set up custom alerts (like a "Remind Me" delay notification if left open for X minutes). (Note: Integration with third-party automation platforms like Google Home or Alexa may require specific setup or separate bridging depending on current platform policies).

A great alternative that provides strong app control and free out-of-the-box alerts and voice integration with Alexa and Google Assistant. It uses a door-tracking sensor and sends immediate status push notifications if the door is left open.

Known for smart auto-open/close features based on your vehicle's GPS, it also excels at tracking door status and sending alerts if your garage is left open unexpectedly.

If you share your preferred smart home ecosystem (Apple HomeKit, Google Home, Alexa, or just a standalone app) and whether you want a free app with no subscription fees , I can help pinpoint the exact model that fits your setup.

Yes. What you want is a smart garage-door controller with a door-position sensor. It can send a push notification if the door stays open for a set amount of time, and many can also close it remotely.

My top picks

• Meross MSG100 Smart Garage Door Opener - $50.99 (Meross Official Store)

• Chamberlain myQ Smart Garage Control - $64.98 (The Home Depot)

• YoLink Smart LoRa Garage Door Sensor - $31.74 (The Home Depot)

• Meross MSG100 — my pick for most people. It adds a magnetic door sensor, phone alerts, and remote open/close control. It also supports Apple HomeKit, Alexa, Google Home, and SmartThings, with no monthly fee.

• Chamberlain myQ Smart Garage Control — simplest if you have a compatible Chamberlain/LiftMaster/Craftsman opener. The myQ app provides real-time alerts and remote control.

• YoLink sensor — best if you only want monitoring. It can send app push notifications, email, or text when the garage is opened and can remind you when it's been left open. It requires a YoLink hub.

One important compatibility issue: newer Chamberlain/LiftMaster openers with a white learn button (Security+ 3.0) aren't compatible with many third-party controllers such as Meross and Tailwind.

If you tell me the brand/model of your garage-door opener (or send me a photo of the motor unit/learn button), I can tell you exactly which sensor/controller to buy.

One important compatibility check: some newer Chamberlain/LiftMaster openers using Security+ 3.0 can restrict third-party controllers, so the exact opener model matters.

If you tell me the brand/model of your garage-door opener (or send me a photo of the opener label), I can check compatibility and find the best current price for one that will definitely work.

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.

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.

• 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.

What I'd buy
