hello,
i know this might be weird but is it possible for openWRT to scheduel the hidden wifi for e.g .. i want my wifi to be hidden from 2:00 am to 5:00am.
thanks in advance.
Technically, yes'ish - but not as a turn-key solution (cron & uci).
It doesn't make that much sense though, as for your clients, both will be different networks requiring different configurations anyways, which would be easier solved with two vAP interfaces (per radio), one normal, one hidden - and you just switching on/ off the non-hidden one as needed (no harm done keeping the hidden one up throughput the day in parallel).
…but, hidden networks are a pain to deal with and actually less secure than non-hidden ones, so I would reconsider your hidden ESSID plans.

You'd probably need to do this with a cron job, as I think that the WiFi scheduler is really just an on/off control.
That said, why do you want to hide the SSID periodically?

Psherman, i really appreciate you so much for your hardwork in this forum helping everyone as possible <3
However .. the reason of hiding the ssid is kinda embarrassing to me lol. I can dm you the reason if its mandatory to tell.
Can you tell the threats i may face by hiding my ssid?
The reason is not mandatory... if you don't want to say why, that's fine. But know that, as already stated by @slh , hidden SSIDs actually reduce security.
The better approach would be to consider using 2 (normal/visible) SSIDs that trade off using wifi scheduler.
Hiding the network name doesn't conceal the network from detection or secure it against unauthorized access. And because of how devices search for and connect to Wi-Fi networks, using a hidden network might expose information that can be used to identify you and the hidden networks you use, such as your home network. When connected to a hidden network, your device might show a privacy warning because of this privacy risk.

It actually exposes your SSID anytime (and anywhere) you're not connected to WiFi. This is because the client must also include the SSID in periodic checks for the hidden SSID to be in range.
