[SOLVED] Bind switch to other switches state

Setup, Configuration and Use Beginners
1

Dear All,

I would like to bind somehow a switch to a logical combination of other switches. So I would like to indicate if “Anyone at home” or “Everyone at home”.

For example let me say I have two switches in my items file:
Switch MeHome “Me” {channel…}
Switch WifeHome “Wife” {channel…}

An I would like to have two switches like:
Switch AnyoneHome “House is not empty” {channel=MeHome OR WifeHome }
Switch EveryoneHome “Everyone is at home” {channel=MeHome AND WifeHome }

The question is if I can do it with some logical binding similar to tha above pseudo syntax or I only can do it with rules and state changes for example?

If the rule is the only option I think I can implement it. But if I could do some kind of binding to a logical combination of other items please let me know how to do it.

Thank you in advance!

You can use a rule that checks who’s home then update your proxy item.

Example:

rule "Presents"
when
    Item MeHome received update  or
    Item WifeHome received update 
then
    if(MeHome.state == ON && WifeHome.state == ON){
        EveryoneHome.sendCommand(ON)
        }
    else(MeHome.state == ON || WifeHome.state ==ON){
        AnyoneHome.sendCommand(ON)
        }
end

Or your can use two group items. One with Or and one with AND.
See the group items docs for how to do that.
No need for rules

Thats exactly what I wanted, thanks!
I already read the doc some time ago but this group state was not clear for me… until now…

Thanks!
