Good Morning,
we need to create a project with many SHELLY relays, with specific time-base activity.
My question is related to the hardware specific, if some models have dedicated RTC clock inside,
capable to restore current date/time after a power loss, and (most important) without wifi
again available, for re-sinc the internal calendar clock.
...and then proceed with normal execute, of the internal schedule stored.
Kind Regards.
Luigi P.
