Payload description
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 Power 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 Power payload with description:
First frame
02:02:01:13:2e:00:11:02:03:4d:2e:00:11:03:03:4e:2e:00:11:04:03:0d:2e:00:11:05:03:54:2e:00:1
1:06:03:4a:2e:2a:11:01:02:ad:2e:2a*
Second frame
02:03:01:16:2e:00:11:03:02:a5:2e:00:11:04:02:70:2e:01:11:05:02:a9:2e:01:11:06:02:a1:2e:09:11
:01:00:01:2e:09:11:02:00:00:2e:09*
*The payload starts building from the 2nd channel of the device. Data for the first channel is taken
from the second measurement and at that point data from the second channel of the second
measurement is cut. Similar case is made in the next built payload.
