I have a Dragino Water Pressure meter and the depth values didn’t seem to be updating. So I was trying to work out which numbers in the raw payload data represented the mA readings of the meter. It turns out the data is encrypted. So you cannot manually extract the payload data you need to have it decrypted by your gateway.
See these:
ASCII payload HEX payload mA reading
DMYAACArAAAA 44 4D 59 41 41 43 41 72 41 41 41 41 8.23
DMYAAB0RAAAA 44 4D 59 41 41 42 30 52 41 41 41 41 7.44
DMYAABnOAAAA 44 4D 59 41 41 42 6E 4F 41 41 41 41 6.06
DMYAABYvAAAA 44 4D 59 41 41 42 59 76 41 41 41 41 5.67
DMYAABKWAAAA 44 4D 59 41 41 42 4B 57 41 41 41 41 4.75
The mA readings have no obvious correlation to the payloads as the payloads are encrypted.
