Can i use my site database as internet of things iot database?

While it may be able to handle it, it probably won’t work:

`Ensuring only web browsers can access your website

Sorry @moheiAldeen, I did not see your mention to premium hosting.

Of course the answer depends on the number of requests, how much work the server has to do per request, and what premium plan you choose.

Without more information, I cannot give you a definite answer.
