Sunrise / Sunset feature not working

I have two Shelly Dimmer's in operation. They both are using firmware 20201007-085347/v1.8.5.

They are connected to the same WIFI network.

I have both set to use the weekly scheduler, controlled by sunrise & sunset.

One dimmer works, it turns on & off at sunset.

The other dimmer does not turn on or off at all.

I have manually set the time zone on both are set to use time.google.com as their SNTP source. Both have the current time set.

What else can I verify as to why the timer does not work on one unit?

Zitat

I always do all settings in the webUI (browser with device IP) and not in the Shelly App (iOS). Try rebooting the device and setting the schedule from webUI, if you haven’t done so already.

I have deleted the old schedule and redone it via the web interface. Will wait to see what happens tonight.

Thought I would post an update here.

I removed the existing schedule and redid it using the web interface directly on the dimmer.

No change.

I did a factory reset and then redid the schedule via the webpage and now the sunrise/sunset scheduler is working.
