Can each jeenode be programmed with a unique address?
Let’s suppose you have say, 50 jeenodes, each monitoring it’s own switch.
When a switch changes state, the jeenode sends it’s address and the new state.
Clearly, to know which switch changed, each jeenode needs a unique address.
You could use the first payload byte as a switch indicator. Jeenodes typically have id’s 1 to 30 in each of groups 1 to 255.
