I have a Digoo DG-R8S for testing - Every 60 seconds the example sketches output the same reading 5 times - is that expected?

dgomes commented 5 years ago

yes it is expected. Since these devices RF is quite unreliable, they retransmit the same message several times, and is up to you to figure out what to do. I have used different software algorithms in the past:

Only take the value if all the retransmissions are equal
Take the value of the most popular transmission (the one with more occurrences)
Take the value of the one which makes more sense (em compared with previous values and physical limits)
