Hi Guys. Liking this controller 
I would like to know how to add in a timer that works like the following:
I have a bunch of Valves (On/Off)
Would like the rule to do the below:
Master Valve - On
Valve01 - On (Run for 10min); then
Valve01 - Off; then
Valve02 - On (Run for 10min); then
Valve02 - Off; then
Valve03 - On (Run for 10min); then
Valve03 - Off; then
Master Valve - Off
Any pointers would be a great help.
