Tuya Zigbee - no switch reactivation after power cut. Firmware or cloud issue?

Hi.
I have a Chinese Tuya- zigbee aftermarket switch.Plugged into a power strip. There are several devices and a home internet router hanging on the strip. Sometimes a reboot of both the router and the other goodies is required. (
The problem is that after remotely switching off the switch or even setting it for 10 sec to automatically switch back on, the switch-on function does not work. It kind of cuts the branch it is sitting on.But the zigbee gateway still has power, only that the net is not there for that moment. In that case, is the device firmware responsible for the re-enablement, or is it decided by the cloud? Maybe I'm doing something wrong?

The cloud. You cannot reboot the router remotely in this way.

Apparently so, but everywhere in the specifications it is written that zigbee can work without a net.Here I have a contradiction.
