Story
This new project utilizes Shelly BLU Door/Window sensors to alert users when a door or window is left open. It is based on the BLE Door/Window Monitor project illustrated here.
How it worksThere are two FSMs (Finite State Machines) that monitor the status of two sensors, in this case, a front and a back door.
When the door is left open for more than 2 minutes, the user receives a notification via Pushbullet.
Shelly BLU Door/Window sensorThis sensor detects and reports the opening or closing of doors and windows, measures tilt angle, and monitors luminosity. It advertises this data in the BTHome format.
Configure the sensors as indicated on the previous project.
BTHomeBTHome is an open standard for broadcasting sensor data and button presses over Bluetooth LE.
BTHome is an energy efficient but flexible BLE format for devices to broadcast their sensor data and button presses. Devices can run over a year on a single battery. It allows data encryption and is supported by popular home automation platforms, like Home Assistant, out of the box.

Pushbullet
Create a Particle webhook with the following shape and form:
The channel tag is provided by Pushbullet and you can read more on this project.
Alerts alternativesPushbullet is just one of many alternatives. Particle Webhooks allow you to connect these alerts to almost any cloud service or server you can imagine.
Here are some options on the Particle console integrations:
If what you need is not in the list, you can use a Custom Webhook to add it. For recording times, you can send this information to services like Google Sheets, Ubidots, Blynk, AirTable, or Firebase, to name a few. This can be achieved by creating two webhooks.
