I’ve seen a few people change the payload as seen below:
to a different word, such as temperature. I’ve also seen multiple payloads listed at once which means sending more than one packet of data. How is this done? I can’t find much about it.
That is a strange assumption. Why would multiple values require multiple packets? I can pack a number of values into one uplink packet.
Have you tried the documentation? If so and something is unclear, please be more specific with your question.
