Total Energy calculation is triggered using virtual switch. Total Energy calculation testing is easy when rule is triggered using virtual switch.
The purpose of sleep 3s is simply to spread the rule’s actions over a longer period of time. The aim is that the performance of the routine has as little impact as possible on the rest of the hub’s operations.
Rules API rule in AWA Rules section
Rules API rules can be added using AWA
Add only actions to rule (to yellow marked area) when you are using AWA Add a Rule
