Bruce may chime in if he gets time, but I would expect that the answer is: it is the same (for all intensive purposes / within margins of error).
Each extra rule probably carries a teeny tiny overhead of its own, but I doubt it is meaningful. It is really the triggers and actions that take all the time.
That said, if I were always controlling the same bunch of devices, I would tend to make a group, and use the group in the rule.
I wouldn't worry about it with such a simple automation. What I would do is create the automation in the app called "Simple Automation Rules" as opposed to the app called "Rule Machine". But realize it really doesn't matter, especially for an automation based on sunrise and sunset (nobody knows the time of sunset/sunrise within milliseconds, unless they look it up, sitting around you would be lucky to be within a minute)
This is how simple it is in "Simple Automation Rules":
They are virtually identical. I'd just do what you say for A. I have moved most of my rules that do things like this to Basic Rule.
This is not what I would suggest at all. This would definitely add a layer of overhead that isn't needed. There is nothing wrong with controlling a bunch of devices directly from an app like Basic Rule.
I would say that depends on the amount of devices though? I often see people trying to turn ON or OFF a load of devices though RM and doing it direct. This seems to almost always fail (because they are not giving any delays), where as if you control a group this manages the delays automatically (it seems).
Why? Assuming these were Simple Automation Rules why move them to Basic Rules? I have a few Simple Automation Rules that I have setup that are working fine. Is there any reason to take the time to move them to Basic Rules?
Then @bravenel let me take the opportunity to say how well you've done on this app. I am impressed by the wide range of intuitive options for conditionals etc, and all linked with a nice flowing English syntax
Hi, I just wanted to check on this post and see if someone can help me I've set up a basic rule to turn a light on the wait for 1 minute to adjust the dimmer, my question is can I set the wait time for less than 1 minute. Thanks
No, this wouldn't happen. The only thing that would cause this Wait to be cancelled is the rule being triggered, and that only happens at sunset. Either A or B work fine, and would be equally reliable and efficient.
