    HI there, I use NodeRed to control home automation. I have a set of rules that look at how much excess solar I am generating (generation less consumption) and then turn on a number of smart switches around the house.

What I am after, is someone who can update the configuration so that when excess solar increases, switch A is turned on first, it waits, it then evaluates if there is enough power to turn on switch B, etc The reverse to apply when excess power drops, turn off switch C, wait, evaluate if sw...
