I run HA on Docker/Synology.
I want to take a snapshot from my doorbell and save that photo with a unique time stamp-file name.
I have it working with setting a helper with filename including date/time. Helper looks OK with value aka the file name ‘snapshot_20230728_13:49.jpg’
Then I save the picture with file name /config/www/{{ states(‘input_text.deurbeldt’) }} expecting a new file /www/snapshot_20230728_13:49.jpg.
But the file created shows up under the weird name SSRP32-0.JPG
