Include a variable in Change Node global variable name

Third party integrations Node-RED

Not sure if that makes sense, but essentially I’d like to know if it’s possible to use “variable variable names” within nodes.

I’d like to set global.light.config.{{payload}} to some value.

This is so I don’t have to have one change node per light name, I’d have to then keep maintaining the flow when/if new lights are added/removed/renamed/etc.

If you can set the whole config at the same time, just can do it that way using JSONata

Alternatively you can use bracket notation instead of dot notation:

The bracket notation works perfectly, thanks!
