Payload decoder
If you want to connect to your own server you have to decode the payload specific to each device. To
do this you need a payload decoder which can be downloaded from
Payload decoder . Extended
documentation of the protocol can be found at Payload description .. An exemplary payload produced
by YO Meter Pulse is presented below with division into each measurement marked together with
decoded values whose interpretation is described in the Payload description document.
Example of YO Meter Pulse payload with description:
