String based feed

Hi All,

so it seems the feed data is number based, my question or requirement would be to have a string feed where i can send messages and see them in the dashboard.
i am building a plant monitoring system, so i want to see messages, like “TIME: started watering plant 1”.

so is it possible to have a string based feed and visualization for ex : last 10 entries in the feed, or does this break current feed architecture ?

thanks, have a nice day.
