Has anyone had a problem with the date and time changing on the Smart Controller between uses? I have set mine manually to Azores Time with no Daylight Saving as I live in Iceland and we are on GMT. However, the next time I switch on the Smart Controller the time and date have changed to something completely different and incorrect for where I am. I then have to reset the time and the date for the correct ones. If I leave it on auto time the same thing happens! Any suggestions please?
