[MSR] Feature request: For Each action on arrays/groups

[toggledbits]

@sebby I'm adding set to power_switch as we speak. Will be in the next build.

To set from a stored variable, use a substitution in the variable value: ${{ expression-or-variable-name }}

I did this exact same thing within Reactor and it became more trouble than it was worth and ultimately removed that rule. A very quick recap of the way I had it was:

Conditions (now triggers):
-- AC is ON
(AND)
-- Motion sensor tripped
Activity (now Reaction):
IF TRUE:
-- GetLoadState of device (entity) and set that to a non-defined variable.
-- Turn the fan on to XX%.
IF FALSE:
-- Turn fan to {variable}%

Now how it became more trouble than it was worth probably could have been solved my adding an additional condition/trigger. If I walked into a room and then back out, but the AC was on, the fan would turn on. No sense in having the fan on if nobody was in the room. Thinking back, I would add that Motion has been detected and needs to remain detected/tripped for 120 seconds. (Assuming that your motion sensors reset in less than 120 seconds)

Thanks guys, my problem seems to be even more basic than all of that. what i cannot figure out is the "service" variable to use for the specific actions. I hope this image works, have tried everything i can think of to make it readable to all.

The x_vera_device.set_variable action is the same as luup.variable_set() on Vera -- it sets the value of a state variable on the device. The service would be a Vera service ID. This is not what you want for turning a switch on or off. You cannot, in MSR or on Vera/Luup, turn a switch on or off by setting a state variable. You have to use an on/off action.

I just uploaded the new build to latest (21218). This has a power_switch.set action that takes a boolean, as you are trying to do here. Update to the new latest build, then in your screen shot above, where you have x_vera_device.set_variable, you will select power_switch.set. It will give you a single parameter in which you can specify a boolean value (e.g. true or false), or use a variable substitution as I posted earlier.

wow, thank you so much for that, as always greatly appreciated.

Hi Rigpapa, I updated the build, the variable is a drop-down with only the true/false option and not a variable that can be substituted. do i need to do something else to make it a string entry?

@sebby said... (see above screenshot)

Based on your screenshot, it kinda looks like you can't (yet) override the two preset drop-down choices in that menu, in order to insert your own ${{ }} expression? (I'm not using 'Latest' so haven't tested myself.)

Whoops! Forgot about that (booleans use a fixed list rather than the generic multi-value path/datalist control)... fix coming...

[sebby]

no rush, i was able to work around it by inserting the status of the fans as a number:

{
"Livingroom Fan" : getEntity("vera>Livingroom Fan").attributes.power_switch.state == false ? 0 : 1, 
"Loft Fan" : getEntity("vera>Loft Fan").attributes.power_switch.state == false ? 0 : 1, 
"Office Fan" : getEntity("vera>Office Fan").attributes.power_switch.state == false ? 0 : 1
}

then used the SetTarget entity action to turn them on or off.

OK. Build 21219 is up, allows expression substitution in boolean.

A couple of other things...

• ...attributes.power_switch.state == false ? 0 : 1 can be more succinctly written as attributes.power_switch.state ? 1 : 0
• The performAction() expression function will perform an action from an expression. If you have an object stored in a variable old_status that contains data like this: [ { id: "vera>Livingroom Fan", status: true }, { id: "vera>Loft Fan", status: false }, { id: "vera>Office Fan", status: true } ], then you can set those statuses in one expression: each d in old_status: performAction( d.id, "power_switch.set", d.status )

This is exactly what i was looking for! thank you!!!!!! i was looking at the docs and completely glossed over that section...
