[Help] Tricky Node-Red automation that test if an old state was true for 5 mins

[sentur]

I can’t wrap my head around how to achieve this new automation in Node Red.

I wan’t to run a script when my phone disconnects from a paired Bluetooth speaker. I have the native HA Android app installed. I have the Bluetooth sensor and Bluetooth connection sensor exposed. The Connection Sensor exposes an attribute that show’s the currently paired device.

What I’m trying to achieve

• trigger: when Bluetooth speaker disconnects and stays disconnected for 10s
• conditions: speaker was connected to my phone for 5 mins or more (this is the bit I can’t work out how to achieve)
• action: run a script.

This is where I’m currently at:

I am currently running version beta-463-3a3577d-full on my phone for reference.

The bluetooth sensor for connected devices is currently a string and not an array so you have to do a string comparison, I think this is an oversight and it might change in the future.

You can follow this issue to see if they get changed to arrays.

Thank you for that. I wasn’t aware of the JSONata element.

@Kermit does it matter that the Wait Until attribute is set to afsada?

[Kermit]

No, the attribute field doesn’t matter when JSONata is selected but I found I a bug that required the field not to be empty even when using JSONata so that’s why there is random text in there.
