Handle multiple sensors in sounds notification

---

I use raspbee contact sensors for monitoring multiple windows in my house. I want to have a Google Device warn me when I leave my house, aka open the front door. Basically this setup is current working with two windows and I have different rules for handling the different cases to get a different warning message:

Window 1    | Window 2    | Message
Open        | Open        | Window 1 and Window 2 are open
Open        | Closed      | Window 1 is open
Closed      | Opened      | Window 2 is open

Now with three sensors and potentially more in the future the manageability isn’t very good.Does anybody has a hint for me how I could solve this without creating many rules more? I’m thinking of setting a variable triggered by the sensor events and use this variable in the warning message.

Thanks for your hints and input.

I realized it with two rules. One for “ok” (everything closed) one for nok (something open).
If “everything closed” is triggered I send a text with the meaning “all is fine”.
If “something open” is triggered I read out the states of my doors and windows via the RestAPI create a text of the open elements and send it to the relevant GH speaker.

Here my API call script. I cleaned it up a little bit.

To announce the $text I am using a variableInputDevice and a rule which reacts on the change of it (I am using this for many different announcements, therefore I am going this way.

The rule looks like this:

When $tts-text-input gets updated then play text "$tts-text-input" vol $tts-lautstaerke on google-nest-hub-wohnzimmer

Hope it helps.

@ortin that looks very promising. Thanks for sharing.

Hello, I use a “Status Display” for the display of various states on windows and doors.
Very roughly described:
This is a picture frame from Ikea. The LEDs behind the white paper are WS2812. So programmable LEDs. The control over takes a Wemos D1 mini. On the Wemos runs tasmota as firmware and the communication from pimatic to the display runs via mqtt.
When the state of a window / door contact changes, then the color of the LED changes.
However without output of a sound. Although this is also possible with a sound module DFPlayer mini. This can also be realized with tasmota and controll over mqtt.

Thanks for your replies and the inspirations. I realized it now the following way:

1. I created a variable “$Anzahl-Offen” for counting the open windows . This variable is increased when a window sensor is opened and decreased when it’s closed.
2. When a certain window is opened I set a corresponding text variable with the name of the sensor like “Window in the bathroom”. The text variable is set to an empty string when the contact is closed.
3. When the front door is opened I check the number of open windows and if it’s greater than 0 I play a text message on the Google Home which includes the text variables from 2. If a window is closed, the corresponding variable is empty and therefore this produces no output. For usability I have two rules. One for one open window and another one, when more than one window is open.

When kontakt-haustur is opened and if "$Anzahl-Offen" equals "1" then play text "Achtung, offen ist: $wc-ofen-text, $bad-ofen-text, $terasse-ofen-text" vol $cc-volumen on CC-Diele

When kontakt-haustur is opened and if "$Anzahl-Offen" is greater than 1 play text "Achtung, offen sind: $wc-ofen-text, $bad-ofen-text, $terrasse-ofen-text" vol $cc-volumen on CC-Diele

For each new sensor I “just” need to add 2 rules which makes it manageable for me. Furthermore I don’t need an external script.
