I have set up 2 photons that send temperatures to Node-Red via MQTT.
One has the topic set to “temp/1” and the other “temp/2”
When I reset each node I see my connect string for both topics but then I only receive temperature readings form the last device I program.
ie. If I program temp/1 then temp 2 nodes, I only get temp/2 readings and visa versa.
I have connection as they each connect and send their own connect message to Node-Red
ie, I see temp/1 Connect and temp/2 connect ok.
