Hello,
I have a Reolink Wifi Doorbell, works fine but the **rich notification** has a cloud platform fee.
So I decided to look for a solution and found one, but it has a flaw.
1. Internet decided to cache the image, that means when doorbell makes a snapshot and overwrite the previous one, it shows the previous picture, that means if Friend A ringed at 10AM and Friend B rings at 11AM I still get the image of Friend A. π
2. Someone mentioned that I could use ?i= in the external link, but sadly I have no idea how to put a random number there.
3. The other and would be the best way to fix it, to make it use a timestamp like this: "YYYY.MM.DD - mm:ss", and as easy it seems I couldn't find a way how. Tried many ways and failed even more.
Can someone help my current flow to use timestamp on **snapshot** and the **external link** at the same time?

So this is really a hard thing to do π
In some ways it makes me happy that I'm not THAT dumb and it is not a 30 sec fix π

Could also be that there are not too many having the same setup & combo like you; using HA, having a Reolink Doorbell and need to control it via NR

Try
```auto
msg.payload = {
data: {
"message":"Someone is ringing !",
"data":
{
"image": "https://inter.net/local/doorbell.jpg?i=" + Math.random().toString().slice(2),
"channel":"Front Doorbell",
"priority":"high",
"ttl": 0,
"actions":
[{
"action": "URI",
"title": "Open Camera",
"uri": "app://com.mcu.reolink"
}]
}
}
}
return msg;
```
That should add a random number eg `https://inter.net/local/doorbell.jpg?i=8445158252631018`
Or for a unix timestamp in milliseconds you could use `new Date().getTime()`
Can not help with HA as not a user, sorry.

Well it is not depending on the hardware, Doing snapshot sending rich notification should work with all the devices, even with a security camera. π
The image caching is also independent from device.
I'm not using NVR, just a doorbell + Wifi router + HomeAssistant π

Thank you E1cid, found another way to save the snapshots, and with YOUR solution the rich notification works flawlessly! π
Thanks for the trip (and the proper syntax)!

Can you share the solution?

It is a simple automation in Home Assistant.
Gave up the NodeRed solution, because it seemed impossible to do.
Put this in configuration.yaml
```auto
input_text:
doorbell_timestamp:
name: Doorbell Timestamp
```
And this to the automation.yaml
```auto
- id: doorbell_snapshot
alias: Doorbell Snapshot
trigger:
- platform: state
entity_id: binary_sensor.doorbell_visitor
to: 'on'
action:
- service: input_text.set_value
entity_id: input_text.doorbell_timestamp
data:
value: '{{ now().strftime("%Y%m%d_%H%M%S") }}'
- service: camera.snapshot
entity_id: camera.doorbell_main
data:
filename: /config/www/Snapshots/Doorbell_{{ states.input_text.doorbell_timestamp.state }}.jpg
```
