Home Assistant, Notification with Images

[noticons]

I currently have this installed and working with Home Assistant to give me notifications by Signal and the Prism app on Android. It works very well and was easy to set up--so, I like that. However, I could find no way of getting images to get passed along with notifications.
(obvious scenario) For instance, if one wanted to use cameras to pass notifications, I would have Home Assistant take a snapshot, store it in a folder--which is simultaneously made accessible through an FTP server on the local network--and have that picture (whether from the folder or the FTP server) passed along with the notification.
I could find no way of doing this with Prism, though. Is this not currently possible?

Nice. Yeah I have a similar setup as you with HA where I have some cameras (eufy) that track movement and notify me if someone is around at bad times. It "should" be able to send images, but I haven't implemented the image display into Prism yet.
I use Prism server here with the Prism-android app which is a better UX than just Signal imo, but I'll look into displaying pictures. I'll need to investigate as it's obviously a much better UX to actually display the picture instead of just displaying its raw link.

I agree about the Signal implementation. I find that somewhat limited. I do like having Signal, however, as I keep all my server-based containers running on the local network and keep a constant VPN back onto the network. It all works great, but if I lose connection with the home-network, Signal can always pass messages, of course. I really like that feature. If it is possible to pass along pictures, that would be great.

android actions

Also, is it possible to include hot-links like tel:########## so if a camera notificaiton is related to something I'd want to make a call about (such as the police), I could just press the link and android would pull up the phone, etc?
Thank you!

The dialer linking functionality should already be implemented on the Signal client side. Signal messenger should already be scanning your messages to add links for phone numbers.

Yeah, it does. It does a good job with that. I was asking for sake of the prism android app, unless you can implement the same link-sensing functionality that Signal has, so that both would recognize phone numbers automatically. That would be awesome.

[lone-cloud]

oh for the android app... yeah, that's very doable to automatically detect phone numbers in notification content and to add custom actions for that. I'll add it in the next day or so.

I added image and tel/mailto action support to the latest Prism and Prism-android app releases.
Notifications without prior actions (eg. not Proton Mail notifications) will have their message scanned for phone and email patterns. If found, those will be added to the notification actions that will be displayed as Android actions via Prism-android app.

To send image notification from HA you'll need an action definition like:

notify:
  - platform: rest
    name: Prism
    resource: "http://<Your Prism server network IP>/Home Assistant"
    method: POST_JSON
    headers:
      Authorization: !secret prism_api_key
    data_template:
      title: "{{ title }}"
      message: "{{ message }}"
      image: "{{ data.image | default('') }}"

and add the data.image URL in the notification action itself like:

action: notify.prism
data:
  title: "Motion Detected"
  message: "Front door camera triggered"
  data:
    image: "https://example.com/snapshot.jpg"

Telegram and Signal channels will download and attach the image to the message on the Prism service side.
For the WebPush channel, the image will be passed through as a URL all the way to the client (ex. Prism-android app) and will be downloaded there.

For all of this to work, you'll need to run the latest Prism releases.
