I would prefer to limit the devices each account has access to but at this point it isn't vital.

Next question, would you explain in simple terms how to commission the bridge to 2 matter controllers?

One final question, do the bridge nodes save stuff to global variables? (I have random globals - `e13811a023b7dca1-measuredValue` for example - which have suddenly appeared)
