<code bash>nano /etc/default/snmpd</code>

protoze nevim proc je zle od zacatku nastavene vymenime posledni radek za
<code bash>SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I extend -smux,mteTrigger,mteTriggerConf -p /run/snmpd.pid'</code>

stahneme z gitu

<WRAP center round important 80%>
1W can only work on pin MOSI; if this pin is already used, you are doomed. NB: on opi0, there are two MOSI, so with a bit of work, it should be possible to use the NAND MOSI for 1W. https://forum.armbian.com/topic/1395-orange-pi-pc-1-wire/?page=2

====== teplota a vlhkost z DHT11 ======
<WRAP center round important 80%>Protoze jsou cidla nespolehliva, umiraji, nespoleham se na ne, navod funguje, ale je zbytecny.</WRAP>
pouzivam pin 14 dle [[https://github.com/Vitalik-Samets/DHT11-Python-library-Orange-PI|DHT11_Python]]
<code bash>mkdir /usr/local/bin/DHT11
cd /usr/local/bin/DHT11
wget https://github.com/szazo/DHT11_Python/archive/master.zip
unzip master.zip
rm master.zip</code>

  * instalace pyA20.gpio knihovny

<code bash>apt-get install python-dev
wget https://github.com/duxingkei33/orangepi_PC_gpio_pyH3/archive/master.zip</code>

  * rozbalit a instalovat

<code bash>python setup.py install</code> 

/usr/local/bin mam DHT11 slozku a soubory humid a temp, ktere volam zabixem

<file python humid.py>
from pyA20.gpio import gpio
from pyA20.gpio import port

#import RPi.GPIO as GPIO
import dht11
import time
import datetime

# initialize GPIO
#gpio.setwarnings(False)
#gpio.setmode(GPIO.BCM)
PIN2 = port.PA14
gpio.init()
#gpio.cleanup()

# read data using pin 14
instance = dht11.DHT11(pin=PIN2)

while True:
    result = instance.read()
    if result.is_valid():
#        print("%d" % result.temperature)
        print("%d" % result.humidity)
        break
#    time.sleep(100)
</file>

pro mqtt ze skriptu "tomqtt" 
FIXME

<file bash tomqtt.sh>
#! /bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
TEMP="$(temp)"
HUMID="$(humid)"
mosquitto_pub -q 0 --retain -h 10.133.1.41 -t temp/kuch -m $TEMP
mosquitto_pub -q 0 --retain -h 10.133.1.41 -t humid/kuch -m $HUMI
</file>

a do cronu co 10min
