Update markdown text over internet

Hello All,

Is there a way to update the markdown text over internet using API?

I want send some text from my VPS Website to my HA to tell me that the “every 3hours” mail backup is done and every night backup of the website is down.

Or if possible using mqtt? but read some difficult setups to do this.

I think i found the solution :slight_smile:

curl -X POST -H "Authorization: Bearer ABCDEFGH" \
       -H "Content-Type: application/json" \
       -d '{"state": "25", "attributes": {"unit_of_measurement": "°C"}}' \
