I'm new to node red and have an issue with multiple devices.
I've managed to send data from my esp via mqtt to node-red. this data is processed and stored in influxDB. so far so good, everything worked.
the next step was to multiply the devices sending messages. when I start my second esp (same code), the MQTT messages are arriving at node red, but the messages from the previous device are no longer arriving. When I reset the first device the messages from the first device are here, but the messages from the second device no more.
It seemed to me that only one device can send on one topic. So I created a new topic for the second device but the results were the same: only messages from one device were arriving at node red.
Thanks in advance
I'm using node red v206
