No data from sensors¿

Hello!

the response returns information about sensor settings - name, parameter, calculation table and etc.
To get last sensor values you can execute request unit/calc_last_message , or to get counters value set up flag Counters to in request search item

and how do I know each sensor ID? do I must check it with the client s front end...or is there any call that will return me the

Senso XX is 1
Senxor XX2 is 2
...
Sensor XXN is n

? maybe?

thanksay

Good day,

in request  unit/calc_last_message  if not specified 'sensors' parameter or empty - return values of all sensors
But this request can return only number values, not text , like in your case value for Conductor.
To get all possible types values it's through request events/check_updates  with "detalization":3. Before it needs to load required units to session - https://sdk.wialon.com/wiki/en/sidebar/ … date_units

the other way just get info from last message as raw parameters - search item with flag Last message and position

Hello!

I/O parameters are raw data, so they can be get only from messages params
as for Engine state - ignition sensor which created for unit - it's possible via request  events/check_updates the same as described above

as request events/check_updates can return time when sensor is get value (0 or 1) you can calculate duration on your side
for  example

ignition: {2: {from: {t: 1578665386, y: 53.9058570862, x: 27.4567871094},…}}
2: {from: {t: 1578665386, y: 53.9058570862, x: 27.4567871094},…}
f: 2
from: {t: 1578665386, y: 53.9058570862, x: 27.4567871094}
hours: 5638064
m: 1578995183
state: 0
switches: 43
to: {t: 1578665873, y: 53.9058532715, x: 27.4573307037}
type: 1
value: 0

start to calculate from last sensor time - to: {t: 1578665873} , in next response  get the same state  - calculate duration, ....etc  then in some response get new value state:1, so process calculation to Off sensor has broken, start to calculate On duration and etc.
