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

Yes — you want a smart garage-door sensor/controller that can detect “open” and send a push notification after the door stays open.

Good options

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

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

• Wyze Garage Door Controller - $52.61 (The Home Depot)

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

• Meross MSG100 — A good retrofit option if you want phone alerts plus remote open/close. It also works with Apple Home, Alexa and Google Home.XCN News |+1

• YoLink Garage Door Sensor — Best if you only care about monitoring rather than controlling the door. It can send app push notifications, but requires a YoLink hub.

• Wyze Garage Door Controller — Adds monitoring, notifications and remote closing, with a camera option depending on the bundle.

• Chamberlain myQ Smart Garage Control — Particularly worth considering if your opener is Chamberlain/LiftMaster/Craftsman; it provides real-time activity notifications through myQ.

One important compatibility issue: newer Chamberlain/LiftMaster openers using Security+ 3.0 may not work with many third-party controllers. The learn-button color/model is important, so I'd check your opener before buying.Lights & Kits+1

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 narrow it down to the right sensor and find the current price.

To get push notifications on your phone when your garage door is left open, you need a smart garage door controller with an open-reminder/overtime alert feature.

Options range from dedicated standalone sensor monitors to full smart controllers that can also close the door remotely.

General Smart Ecosystem Sensors (Aqara, Ring, or SmartThings)If you already use an ecosystem like SmartThings, Home Assistant, or Apple Home, you can attach a simple zigbee/z-wave contact sensor (like an Aqara or Samsung multi-purpose sensor) to the top panel of the garage door and create a custom automation: "If door is open for more than 15 minutes, send push notification."gotailwind.com[2][3][4][5]

To help narrow down the best pick, let me know:

• Do you use a specific smart home ecosystem (Apple HomeKit, Amazon Alexa, Google Home, or Home Assistant)?
• Do you just want an alert , or would you also like the ability to remotely close the door from your phone?

If you mainly want a phone alert when the garage door has been left open, I’d look at these:

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

• YoLink Garage Door Sensor — specifically supports “left open” reminders, with push notifications, SMS, and email. It requires a YoLink hub.YoLink

• Chamberlain myQ Smart Garage Control — good if you also want to close the garage remotely. It includes a door sensor and sends phone notifications.The Gadgeteer

If you tell me your garage-door opener brand/model (e.g. Chamberlain, LiftMaster, Genie), I can narrow it down to a compatible option.

Here are the best options available for getting push notifications when your garage door is left open, ranging from budget smart controllers to dedicated standalone sensors.

Chamberlain myQ Smart Garage Control
This is the most popular add-on device if you already have a standard overhead garage door opener (manufactured after 1993). It uses a small wireless sensor attached to your garage door and a hub that connects to your home Wi-Fi. Through the myQ App , you can easily set up "Remind Me" alerts to push a notification to your phone if the door stays open for a specific duration (like 10, 20, or 30 minutes). You can check out the device details on the Chamberlain Smart Garage Control via Ring page.

YoLink Smart Garage Door Sensor
If you want a reliable standalone sensor that doesn't necessarily rely on controlling the door mechanism itself, YoLink is fantastic. It uses a long-range wireless protocol (LoRa) so it won't drop connection even through thick garage walls. It specifically features "door left-open reminders" and hooks right into your smartphone via their app, with integrations for Alexa, Google Assistant, and Home Assistant. You can view the hardware details on the YoLink Garage Door Sensor Store.

Tailwind iQ3 Smart Garage Controller
Tailwind is heavily praised in the smart home community specifically for its reliable automatic closing and "left open" alert capabilities. It uses a wired or Bluetooth sensor tracking system and features smart departure/arrival logic to alert you or automatically close the door if you drive away and leave it open.

To help narrow down the best fit, tell me:

• Do you want to remotely open/close the door from your phone, or just monitor it?
• Do you currently use a specific smart home ecosystem like Alexa, Google Home, Apple HomeKit, or Home Assistant?

Yes — what you want is usually sold as a smart garage door controller, which includes a door-position sensor and sends push alerts when the door stays open.

My top picks

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

• Tailwind iQ3 2.0 Smart Garage Door Controller - $89.99 (Go Tailwind)

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

• Best premium option: Tailwind iQ3 — particularly good if you have multiple doors or want sophisticated automatic close/vehicle features. It supports notifications after a configurable period of time.Tailwind Support

• If you ONLY need sensing/alerts: YoLink has a standalone garage-door sensor that can send push, email, and text alerts, but it requires a YoLink hub.

One important caveat: compatibility depends on your existing garage-door opener. In particular, newer Chamberlain/LiftMaster openers using Security+ 3.0 can have compatibility restrictions with third-party controllers.lightsandkits.com

If you tell me the brand and model number of your garage-door opener (or send me a photo of the motor unit), I can tell you exactly which sensor/controller I'd buy and find the best current price.

To get push notifications when your garage door is left open, you generally have two main approaches: an all-in-one smart garage controller/hub (which also lets you close the door from your phone) or a standalone wireless contact/tilt sensor paired with a smart home hub.

The top options on the market depend on how you want to set it up:

Standalone Smart Tilt Sensors (Aqara, Aeotec, or Ring)If you already use a smart home ecosystem like Apple HomeKit, SmartThings, Home Assistant, or Ring , you can buy a dedicated wireless tilt sensor (like the Aqara Vibration Sensor or a Z-Wave/Zigbee garage tilt sensor ) and place it on the top panel of the garage door. You can then program a routine in your platform of choice: "If garage door is open for more than 15 minutes, send a push notification to my phone."cunninghamdoor.com+1

To help narrow down the best fit, tell me:

• Do you already have a smart home ecosystem (like Apple HomeKit, Alexa, Google Home, or SmartThings)?
• Do you want the ability to remotely close the door from your phone, or do you just want monitoring and alerts?

Yes — what you want is a smart garage-door controller with a door-position sensor, rather than just a basic alarm sensor. It can send a push notification if the door remains open for a specified amount of time.
