Taking into account you want to control a 16amp motor with the shelly, would't it be better to attach a contactor to the shelly itself to avoid the shellly relay wearing out after many turn-ons ?
PS: I'm trying to help but, bare with me, I'm newbie to this shelly world

Nordlicht_2023, thank you for your detailed answer.

So even a short power loss will unsync the schedule I need. Mehhh..
> Perhaps you can configure Wifi 2 with a mobile hotspot (smartphone etc.). So the shelly can connect the hotspot if its in range and it can get the time from time to time.
I need to convince someone to set their phone in hotspot mode when in the area and always use the same phone/credentials.
This might do the trick, but not reliable due to our human nature...Too bad there is not a simple and reliable solution for my little offline project. I've even been thinking about setting a NTP server on a RaspberryPi with a RealTimeClock module attached. But, the more I think about it the more overkill I see this solution to fix such a simple problem.

Hi, newbie here.
I need to have some appliances ON on non-holiday weekdays during work hours. And, I see the Shelly Plus Plug as a good candidate for the project. The main issue is that the project is for an offline environment and no local NTP server is available. However, there's no issue in configuring the Plug while being online.
Is it possible to run the scheduling cron script properly if the Shelly will be offline most of the time?
Does the plug keep clock time when it has no current? (like a desktop computer does)Any idea on how much the internal clock will drift over time if being offline?
Thank you!
P.S.: I found this other thread but it didn't quite answer the question and since it's old (2021) the forum recommendation was to start a new one.
