Public Service Announcement to all Ecodan owners:  don't forget to turn off Summer Time in the Initial Settings menu - the software isn't clever enough to self adjust, unfortunately...

@downfield I have never been aware of that one. Every day is a school day. Now, where to find that setting? 🤔

14 x 500w Monocrystalline solar panels.

2 ESS Smile G3 10.1 batteries.

It's the one before the Service Menu.

I only realised a few weeks ago that my system has been on Winter time most of the summer!

@downfield I found the setting and 'Summer Time' was turned OFF.

@downfield, wow that's crazy that it needs a manual change.

Having said that, we have a snazzy robovac at home, and if you change the time to BST and enable "daylight savings" it knocks our schedule out by eight hours. Something that is potentially quite simple, yet apparently isn't.
