We are planning to add support for using sunset/sunrise times (with +/- offsets) in a program from the next firmware release. The current firmware can already obtain and display sunset/sunrise times (and it’s made available so we can collect feedback on it and check if there are any major issues). Support to use them in a program will be added next.
Could you post a link to your mechanical relay with 24VAC coil? The question of 24VAC relay often comes up and I am curious which one you’ve got. Thanks.
