   curl http://192.168.119.236:8088/rest/all [{"circuit": "1_01", "debounce": 50, "counter": 0, "value": 0, "dev": "input", "counter_mode": "disabled"}, {"circuit": "1_02", "debounce": 50, "counter": 0, "value": 0, "dev": "input", "counter_mode": "disabled"}, {"circuit": "1_03", "debounce": 50, "counter": 0, "value": 0, "dev": "input", "counter_mode": "disabled"}, {"circuit": "1_04", "debounce": 50, "counter": 0, "value": 0, "dev": "input", "counter_mode": "disabled"}, {"value": 0, "pending": false, "circuit": "1_01", "dev": "relay"}, {"value": 0, "pending": false, "circuit": "1_02", "dev": "relay"}, {"value": 0, "pending": false, "circuit": "1_03", "dev": "relay"}, {"value": 0, "pending": false, "circuit": "1_04", "dev": "relay"}, {"value": 0.028138793129200895, "circuit": "1_01", "dev": "ai"}, {"value": 0.01768108541555532, "circuit": "1_02", "dev": "ai"}, {"value": 0.006, "circuit": "1_01", "dev": "ao"}, {"interval": 15, "value": 23.95, "circuit": "2", "address": "282B63C1070000C3", "time": 1513704665.414423, "typ": "DS18B20", "lost": false, "dev": "temp"}]

   
   

2. The DS18B20 is our One-Wire sensor. It has the address 282B63C1070000C3. In the same line, we can see the interval being set to 15.
3. Now we change the configuration of the UniPi itself. Open up the evok-neuron.conf file.

   
   

   Code Block
   sudo nano /etc/evok-neuron.conf

   
   

4. Now add the following to the file (all the way at the bottom).

   Code Block
   [1WDEVICE_2] bus = 1 address = 282B63C1070000C3 type = DS18B20 interval = 1

   
   

5. Make sure to change the address accordingly.

6. Now just restart the required service. 

   Code Block
   sudo service evok restart

   
   

7. Now the One-Wire sensor should read about every 2-3 seconds. Due to limitations, it does not read every second.
