Custom Integration : Tuya Smart Doorbell

Good morning every body,

I have buy a new Tuya doorbell, and i try to integrate missing properties.
Simple property is easy to implement but i’m block to one specific.

Tuya doorbel send link to the latest snapshot when user click on the doorbel.
The link is base64 encoded on amazon cloud. This link is valid only 1 minute. On tuya code, i try to save the image on local via the service call “downloader” but they freeze my application. Do you know another way to save a image on homeassistant framework?

Thanks in advance
