Hi, I have multiple devices that can connect via MQTT into my node-red application. Every device has a unique ID (let's name it devID). I need to keep a bunch of state information for every device separately, and the states are the same for all devices. State examples: IDLE, TXING_DATA, RXING_DATA,…

By the looks of your code you are storing each value separately. By not store 1 object with all values? I could store one object to hold all devices' states, something like: globalObj = { dev1: {state: 'IDLE'}, dev2: {state: 'TXING_DATA'}, dev3: {state: "RXING_DATA'}, // ... }; /…

[image] RGNagel: I meant something like this: Given a variable ( devID ), I would like to get a global object based on that variable. [image] You can with JSONata (or a function node or the subroutine nodes)... [1Ck0hX9qBi] [{"id":"400bd21a.2b524c","type":"inject","z":"64ce1d00.d049e4","na…

This is awesome! Thank you, Steve. I know nothing about JSONata expressions
