Completely misses my point. I understand the in/outs of these devices.  I'm not talking about a power outage.

It's a pain to have to create an off/on schedule to just remotely power cycle a device (i.e. a router or WIFI) connected to the smart switch.  Then have to go back and disable or remove the scheduled action.

There is an On/Off button in the app.  It would be fairly easy to add the combined Off then delayed (i.e. 5 or 10 seconds) back On command set in a button.

In the IT Support realm I work in we use various different "web switches" to remotely control the power of devices such as routers, servers, and other appliances.  The web switches all have a "reboot" (Off then back On) feature.

This is one of the devices we use.   networktechinc. com/download/d-control-power-reboot.html

If these smart switches had this added capability we would only need to use the Kasa devices.

Thanks for listening and responding.

I came here today to request the same function. Power Cycle / Reboot with perhaps a time parameter that could be user defined e.g. 30 seconds to turn the switch back on. When I am away from home sometimes the router needs to be rebooted as I cannot access certain devices in the home. I do not know why this happens, but a power cycle of the router often resolves this issue. I also run a PiHole and it sometimes needs a reboot, and even my Verison fiber optic terminal can use a kick. For the router and the Verizon box, if I turned them off, I'd be locked out and would have to manually turn them back on. Would be great to be able to do this via HomeKit if possible or via the TP Link App outside the local network.
