Thanks for the replay. I’ll check if I can combine timming settings with some additional scenarios (less reliable) to cover my irrigation needs otherwise plants will die this summer 
Still big surprise this chip limit…such a capable device with this huge fail… for 4 channels with just 2 schedules gives you already 16 timing needs…
From eWelinks perspective, a way to avoid this I would implement a feature where you can setup some interchangeable timings. you set both, when one completes, it changes with the other one in the background… I understand it wouldn’t be 100% reliable but maybe give that option with some coloring alerts…
