Feature request (if it makes sense)
If NTP enabled & NTP configured & NTP updated_since_last_powerup If WiFi_just_went_down Store current date/timestamp to flash / permanent memory @ Power up, during flash reload: If date/timestamp NOT Null Load date/timestamp from flash
This way, WLED has a date/time stamp that is at least close even if NTP is unavailable (internet connection failed), but power is still available.
If it’s way off, people will understand. However, for a brief power outage followed by a prolonged internet outage, most time-based automation configured in WLED will still operate relatively close to the right time/date.
This might be a WLED 2.0 feature, but throwing it out there as people are gearing up for fall and winter outdoor light shows and automations, in case it is super easy to do and there is available flash storage for it.
Comments welcome by anyone, especially anyone with better ideas.
