Now that the lights almost complete. I thought I'd have a little play with the scheduling on the sonoff and see what happened.
6pm ch1 strips on
6.04pm ch3 cobs on
6.05 ch1 and 3 off.
Almost jizzed a little watching it lol. Sonoff th10a is definitely going on the 4th relay and down to the heater. Because I'll be able to utilise that to make a scene for the sonoff to switch cobs off if temps exceed 26c (for example) and just leave strips running. You can also set different schedules via a calendar so photoperiod augmentation has just become a majorly easy task. Don't even have to stand up.
Cheers @Albannach bro I know you been watching closely i'm glad I didn't disappoint
