Ladder logic in HS4

[metkhoo]

retiredjeff The logic of an if/then/else is
IF (Condition)
THEN (condition is true)
Do things because the condition is true
ELSE (condition is false)
Do things because the conditon is false
ENDIF

In HomeSeer, the condition is actually an EVENT/TRIGGER.
This makes it rather difficult to get an ELSE (event didn't fire/trigger didn't happen)

Another former Stargate user here and IF-THEN-ELSE programming is one of those things you sorta have to live with to understand and appreciate. Once you learn to use it, it becomes super valuable. I definitely miss it here in HS World. Unfortunately Stargate as a stand-alone died due to a lack of innovation, and while HS2 had a plug-in to harness its excellent I/O capabilities, that was killed off in HS3. So please throw us a bone and give us IF-THEN-ELSE.

Have you all been following this thread where changes to the Events are being discussed. Currently ELSE is not in the proposed round 1 changes (stated it may be in a future update), but additional sub-conditions are and would allow for an Else type scenario by just doing the opposite IF. It would not work under the initial trigger (wouldn't actually make sense to for many devices such as an On/Off unit as one of the two would always trigger), but would be under the Conditional sections:

When Device1 is changed to On

Then

If Device2 = On

Set Device3...

If Device2 = Off

Set Device4...

This post in the thread shows a requested END statement to stop processing as well as the current suggested changes (Everything but the Yellow portion).

Not sure what point you are making metkhoo . The way it works would be,
If time is after 10am
and if time is before 11am
then turn light on
else turn light off

So if the the event engine is checking for conditions every 100 Milliseconds for example; between 11am and 10am the next day, it turns the light off (396000 times).

I should also mention if something else turned the light on, it would be turned off again!

Instead of viewing HomeSeer in a traditional programming manner using "IF-THEN" logic, I find it useful to think of HomeSeer logic like this:

WHEN an EVENT is triggered
AND various CONDITIONS are met
THEN peform ACTIONS
