I have a Node MCU board and I have a working sketch which subscribes to a channel, and published to a channel.
However I would like it to subscribe to 2 channels.
I can’t work out how to do that.
This is the code so far - only as an offering that I have it working.
If you want, look at the code and show me where to add the required code, or:
Show me some code which subscribes to 2 topics.
Thanks in advance.
