Reboot Device?

[schuergs]

Hi all, it's annoying:

I have a curtain device which loses WIFI connection after a couple of days and does not re-connect to Wifi. As an additional complication, it's built into the wall behind the original physical switch.

Pinging all my devices regularly (every 15mins or so) partially works - the WiFi AP doesn't drop the connection then - but after a couple of days the (weak) connection on the device is gone for good.

Rebooting it via switching off & on the room's fuse works, but that's not how a reboot should work on a regular basis, as there are other devices and my WiFi AP on the same circuit.
Any other was to reboot the device?
I tried RENAME_GW to force it to re-connect, but I have no idea what the parameters should be like.

Greetings,
Stefan
