ESPHome flashed plug. Shuts off at 3am

I have flashed a few devices to ESPhome using tuya-convert. One is a Kogan Smart Plug, the other is an Arlec Powerboard.

I have tested them both with my Modem plugged in, so I can switch the modem on and off if the internet fails. At 3.03am most nights, the plugs reset themselves, losing power to the modem. The power comes back on, so it’s fine, but I get a lot of alerts from my Unifi kit about the internet going down.

Has anyone else experienced this? Is there a way to keep the device on constantly if it does some sort of self check?

Thanks

And are you going to show us your yaml config file?

And no they do not switch off once every 24 hours unless you tell them to.

This is the code from one of the kogan plugs.

They’re not technically switching off, just off and on very quickly causing the modem to lose power and come back on.

Unplug the modem from the smart plug and monitor the wifi overnight.

A possible scenario:

  • Wifi drops out for whatever reason (scheduled restart/reboot?).
  • Smart plug attempts wifi reconnection, fails, and reboots***
  • This causes the modem to loose power momentarily and restart, restoring wifi.

***

ESPHome reboots on purpose when something is not going right, e.g. wifi connetion cannot be made or api connetion is lost or mqtt connection is lost. So if you are facing this problem you’ll need to explicitely set the reboot_timeout option to 0s on the components being used.

I’ve done some testing. Seems to be the Wifi drops as you say, which reboots the switch. I’ve used the reboot_timeout option for now. Is there a way to make sure that socket comes back on after a reboot? Seems to not reboot to same state.

Looking into why the Unifi drops. I think it may be plex libraries updating, but need some more digging.

Yes use the switch option restore_mode:
