If a device in Homey can generate an image, such as a camera snapshot, you can use that image in a Flow and send it as a push notification to a user.
- Open an existing Flow or create a new one. 
- Add a Then card.
- Go to Push Notifications → Send image [Image] with message [Message] to [User]. 
- Select the image tag you want to use.
- Choose the user who should receive the notification.
- Optionally, add a message to include with the image.
- Test your Flow and save it.
