You can't. OTA is a server-client operation, using HTTP. One server, one, and only one, client. Anything else, you'd have to write yourself. You could setup a mechanism for each client to periodically check with the server to see if an update is available, and, if so, fetch it. But, again, you'd have to design that mechanism. And, if you wanted it to be fully automated, you'd also have to modify both the OTA client and server code.

So, I cant just find my devices in my local network and update each one of them?

Of course you can, manually, one-by-one. You cannot do them all in a single update.
