Evok does not display data from sensor the DS18B20 but in Mervis or raspbery it do

[KaniaGandzowski]

I have got UniPI and raspberry PI 3.

I want read temp from evok api

root@unipi:/sys/bus/w1/devices# wget -qO- http://10.2.11.149:8088/rest/sensor/1
{"interval": 1, "value": null, "circuit": "1", "address": "280416C20BF3FF", "time": 0, "typ": "DS18B20", "lost": false, "dev": "temp"}root@unipi:/sys/bus/w1/devices#

value is empty (null) but in

root@unipi:/sys/bus/w1/devices/28-0416c20bf3ff# cat name
28-0416c20bf3ff

root@unipi:/sys/bus/w1/devices/28-0416c20bf3ff# cat w1_slave
c7 01 4b 46 7f ff 0c 10 fe : crc=fe YES
c7 01 4b 46 7f ff 0c 10 fe t=28437

And can read from Mervis

@KaniaGandzowski Does the sensor shows up in the web interface of evok or in the output when evok is run on hand? It might NOT work if you have all three softwares on one system running at the same time..

[KaniaGandzowski]

no

does Mervis has an api? or how connect with zabbix

[tomas_hora]

@KaniaGandzowski The easies API for Mervis is TCP Modbus. What about my comment: It might NOT work if you have all three softwares on one system running at the same time..
