Very easy for the electrician to install.
When setting up schedules through the app, they’re out by 1 hour, so a heads up for anyone there.
Had the first trip off due to over temperature today, checked the front of the device soon after as I was home and didn’t feel too warm to me, but being an electrical engineer my idea of too hot is vastly different to others. Was able to turn one of the loads back on stright away so no big concern there. I did have 2x 16A loads running for over 2 hours consecutively to get to this point.
