I'm using a file to write and read logs comming from MQTT.
This is read in an HTML "ui-template".
That's great because when the file is too long, a scroll bar is added automatically.
Is there any way to scroll down with programming ?
When a write occus, I trigger the read so I will be able to trigger the auto scroll. The read give a msg.payload to the template.
Do you have any idea how to auto scroll ? Whithin the html template or outside ?
If not possible, I can add line to the top of my file instead of an append (at the bottom). But the only way I know to append at the top is to read the file and overwite it then, while adding the line before. I guess that's bad for performance and ssd wear...
