Working like a charm :-)
root@orangepizero:/etc/rpimonitor# cat /sys/bus/w1/devices/28-020b92459bc7/w1_slave 6a 01 55 05 7f 7e 81 66 1d : crc=1d YES 6a 01 55 05 7f 7e 81 66 1d t=22625I've lastest available version of RPi-Monitor on my Orange Pi Zero:
Version: 2.12-r0 by Xavier Berger
I tested both values:
t.(d+)$
and
t=(d+)$
Those values are used in conf file, in my case custo.conf witch is mentioned in main config file /etc/rpimonitor/data.conf
Of course, after each change I restart service with command:
service rpimonitor restart======

I found that this two sections are only important for drawing temperature stats:
dynamic.18.name=045 dynamic.18.source=/sys/bus/w1/devices/28-020b92459bc7/w1_slave dynamic.18.regexp=t.(d+)$ dynamic.18.postprocess=sprintf("%.2f", $1/1000) dynamic.18.rrd=GAUGE web.statistics.1.content.18.name=045 web.statistics.1.content.18.graph.1=045 web.statistics.1.content.18.ds_graph_options.045.label=045 (°C)What I'm not sure is regular expression, can someone tell me how to extract only temperature value from this command?

Armbianmonitor:
Dear Armbian friends,
I have question about add DS18B20 temp sensor at RPi-Monitor (web based interface).
Can somebody paste working config of this sensor?
On internet I found many tutorials but with DHT sensors.
On this page (Xavier is an author of RPi-Monitor I think) is described DS18B20 but in status "Working in progress".
I tried this but without luck.

Cheers,
Lucas

I'm back :-)
Well, it's working! Almost..
When I checking temperature not evey response is proper, some anwers are with "crc=c9 NO".
I have checked wiring and connections on board few times, changed resistor and cables.
Do you have any idea?

EDIT:
Okay, I got it
echo 408000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
Default was 120000
root@orangepizero:~# more /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 120000
I found answer in this topic:
-
New sensor (DS18B20) is in delivery, I expect tomorrow I should get it.
Cheers!
-
Thank you for taking your time on tests
My cpufreg now looks like
root@orangepizero:~# more /etc/default/cpufrequtils # WARNING: this file will be replaced on board support package (linux-root-...) upgrade ENABLE=true MIN_SPEED=480000 #MIN_SPEED=240000 MAX_SPEED=1200000 #GOVERNOR=ondemand GOVERNOR=interactiveBut nothing is discovered.
I hope that new sensor will come soon!
Stay tuned ;-)

A moment ago I have ordered DS18B20.
Hope it will do the job.
When you mention about this model I found that this guy also used it.
https://www.norwegiancreations.com/2017/06/do-it-yourself-snmp-temperature-monitoring-system/
When DS18B20 arrive I will write if it helps.
Cheers!

I have three samples of DHT11, one of them is equipped with diode but it seems that this model isn't compatible.
I will order DS18B20.
Can someone confirm which temperature sensor is working on Orange Pi Zero (with H2+)?
-
Checked.
On 20k scale is 4.68 so it looks like 4k7.
I also tried another sample of resistor to be sure that this is not the case. No changes.
-
Thank you for answer.
I have switched between kernels (installed bionic image):
4.14.70
4.14.84
4.18.8
Nothing changed. Seems that it's dead end - it's not a kernel issue.
Any other ideas?

Armbianmonitor:
Dear Armbian Friends,
My temperature sensor is not detected by board.
Can somebody give me some advice what should I chceck / change / test now?
Cheers!
Lucas
I tried:
- another sample of DHT11
- changed cables to different ones
- changed
- both tested sensors were connected with 4.7k resistor between positive and data cable
- tried different system versions like bionic, stretch and now jessie
- tried to load modules via /etc/modules-load.d/modules.conf

OPi Zero - add DS18B20 temp sensor at RPi-Monitor
in Orange Pi Zero
Posted
Thank You Frank,
I will check it at friday. At the moment I don't have access to my Orange Pi.
And of couse I will write down my results.
Cheers!

It works!
I only commented out humidity parameters - rest is as You suggested.
Thank You once again for help FRANK333 :-)
One additional question:
I messed up a little bit with setting correct time on my Orange Pi Zero. I changed it and now it's correct, but not on stats graph.
On browser tab with Statistics there is still incorrect time displayed.
=================
--------Edited--------
=================
SOLVED!
To solve issue with incorrect hours on stats page graph I found rrd file in /var/lib/rpimonitor/stat directory.
Simply remove and restart RPi Monitor did the trick.
Cheers!
