Weekly Schedulle for Shelly PlugS if Offline

  • Hello,

    The Weekly Schedule page of the Shelly PlugS says that for this feature the Shelly PlugS must be online to sync the time.

    It is logical that in order to setup the feature the connection is required.

    Now what if for a reason the house router goes down, will the programmed Schedule still be executed by the PlugS locally?

    In other words, where the schedule is executed?

    Is the weekly Schedule ran locally on the PlugS which would continue turn itself on/off while waiting for the network to be back?

    Or are the on/off commands sent from the cloud to the PlugS?

    I understand that if he PlugS run the schedule locally and it is not online the time can drift.

    Many thank for sharing your experience.

  • In other words, where the schedule is executed?

    the weekly schedule is a device-internal feature and will be executed, even if your router is temporary down..

    Time is synced on every boot/reboot. As long as the Shelly doesn't reboot schedules will work as expected.

    Note: it's also possible to use a local timeserver (a computer or router with NTP server feature istalled). Then you don't need a internet connection at all..

  • Thank you Seven of Nine , Indeed !

    Shelly official support gave me the below answer that I found surprising. I could not imagine they run a central scheduler server for all devices and send out commands to turn them on/off. Not only for the "Weekly Schedule", but also for the Timer evens! I think they confuse the need to access a time sever from time to time and run the scheduler.

    Zitat

    Support: Let's say you have scheduled your device to turn ON in 1 hour with the weekly schedule. If your network is down 5 minutes before that, the schedule will not be executed as it's based on the internet and time as you said.

    Me: Is there a way to have a schedule for PlugS that can be effective even if the device is offline?

    Support: Unfortunately, this is how the weekly schedule works on all devices. It cannot be executed without a network
