there must only be ONE broker so that i can communicate values to/from your clients -

- in this case we will use the mosquitto broker you installed on 192.168.1.15
- All clients (node-red) publish (broadcast) to 192.168.1.15
- Anywhere you want to receive that message subscribe to the topic on 192.168.1.15

this way - the ONE SINGLE broker knows to push any published messages to the clients (other node-reds)
