Switch & timer activation -beginners question

[RoelofS]

Hello,
with the help of my son I have installed Domoticz on my Windows PC. or rather on a Synology-NAS connected to my windows PC.
It communicates with a (Chinese) Xiaomi Gateway device, which sends & receives data from temperature sensors, door-sensors,
and (Philips Hue) lamps/dimmers. Most of the system works as intended....
My question relates to the timer function in the "switches" application in Domoticz.
I can switch the (Philips HUe) lamps on & off by hand (clicking on the lamp icon ); I can control the dimming function , I can set "ON" and "OFF' times in the "Timers" window of the respective Switch in Domoticz... but the lamps don't switch On or OFF at all at the times I set them to...which is evident when you look at the lamp, but also the log file indicates no timer induced action whatsoever, only the "hand" commands...
I did tick the "enable" box in the "timers" window, set "everyday", clicked "update" - what more can I do ?
I tried multiple options of the timer settings - Sunrise , On Time,
which hidden box am I missing?
thanks for your help,
RoelofS

Have you setup your location: Setup->Settings->Location?

[RoelofS]

I tried, but the system refuses to accept it, ie it ignores it. I can let the system "automaticallly" find my location/ longitude & latitude.
Going out of the "setting" mode, and then back into it, the location is already forgotten. I can't find the "confirm new location" button, if there is such thing.

Tried "Apply Settings" after change?

[RoelofS]

I just did... couldn't find that button; because it was hidden under a persistent "update now" window that I couldn't get rid of!! ( see my question
"Update endless loop" )
I was able to temporarily remove that box, and then saw the thusfar hidden button that I had a strong feeling must be somewhere....
I'm still trying to get the "update now" window removed; it keeps reappearing. My current D. version# is V3.8153
Clicking on "Update Now" doesn't work (entering loop...) nor does "update Domoticz" under the Setup pulldown menu..
At least I can watch this evening if my system knows the sunset time now, and activates my outdoor light appropriately.
Thanks anyway, you confirmed my suspicion that there must be an "apply" button...
