I meanwhile think that it is not due to my sensors

Hi Theyosh, I'm 100% sure it's not on my sensors or on my cables. It has to be a hack on the software. Otherwise I can not explain it anymore ... at some point the values (temp. and humidity) are gone.

Last picture indicates that the quick fix is to remove the settings.cfg file and restart. This means reconfiguring your setup. If that does not help, more investigation is needed.

I have no time to test it my self. But I do not have problems with 1wire sensors. I have two running for months now.

[vanessa2013]

Should I possibly redo the whole rasp?

[theyosh]

No. Only make a backup of settings.cfg and remove it from the PI. Then restart. You have to reconfigure the software again. I do not have an explanation why this is happening.

[vanessa2013]

Thanks for your tip but unfortunately he brings nothing for me, currently your interface may have some errors otherwise there is not ...

[theyosh]

Ah, I see.

I am sorry, but I did change the code to use only GPIO numbering. So for your DHT sensor use real GPIO port number which is 40. Enter 40 as new Address. That will also change the ID of the sensor. So after changing it to 40, go to system -> environment and chose the right sensor again and save the new environment setup.

I can a bit confusing right now. But I thought that it would be easier for the consumer to enter either only REAL GPIO port numbers or only BCM. But BCM is than limited, so I chose for REAL GPIO.

My software translate the GPIO portnumbers to right BCM numbers in code.

Hi, thanks now everything works fine. Two still ask, it is possible in the future by remote control (Nodemsu 8266) switch. And is it possible at some point to turn off the heating with door sensors when the door is open, so the heater turns off (as with the sprayer).

[theyosh]

Ok, nice that it is solved.

Regarding Nodemsu: Nope. I will not make support for external devices directly. There is now an option to add remote sensors through HTTP. So technical it is possible already to support Nodemsu. But you have to program yourself the webserver on the Nodemsu. And that way, the Nodemsu could produce JSON output which can be used with my software. But again, I will not give support on how to develop for a Nodemsu.

About turning off the heater when a door is opened, I suggest to open a new issue. And stick to only 1 problem per issue.

[vanessa2013]

Ok, all right, I still have a problem, my DS18B20 sensors always stay at 17 degrees, although it is warmer. It also does not help to empty Chache

Hi, the problem is not the sensor but where else, as soon as your interface queries the sensors, the sensors disappear under cd / sys / bus / w1 / devices / && ls and there is only w1 bus master present. Did you change something in the code? Only when I start Pi again, all sensors are back, until the interface interrogates again.

[vanessa2013]

Unfortunately, this problem is still after the update :-)

[theyosh]

Hmmmm, can you try the following:

go to /sys/bus/w1/devices

and enter a folder that starts with '28-'

there enter the following command:

cat w1_slave

What it the outcome of this? An example:

cat w1_slave
56 01 4b 46 7f ff 0c 10 7b : crc=7b YES
56 01 4b 46 7f ff 0c 10 7b t=21375

[vanessa2013]

Yes I can
