HS100 - Can't get Sunset to work properly
I have been using my HS100 very sucessfully to control a lamp in my hall - originally coming on at 4pm and switching off at 11.30pm (using the schedule facility). It all worked perfectly.
However, I've recently changed things to make the start time be sunset, which is currently 4.20pm in the UK. Despite the time and location settings being correct and synced, the HS100 is determined to switch on at 6.10pm ie nearly 2 hours after sunset.
I've tried changing various settings including timezone and location but it remains stuck on about 6.10pm (moving by a minute or so each day as one would expect). Time zones are interesting - I'm currently using the one labelled GMT, although there appear to be several for the UK eg Europe/London, GB, GB-Eire, GMT+0, GMT-0, GMT0, and Greenwich. Are they all the same and is there one which changes automatically to BST in the summer - ie which is the best one to use?
Would appreciate any help anyone can give me on this.
PS Sorry, not sure where to find the firmware version
