DHT22 and DS18b20 on same node: DS shows up with Humidity now.

[torfinn]

Hi ! You can get a partly workaround using V_DUST_LEVEL or something instead of V_HUM.

This is a really annoying thing.
I finally decided to modify the Domoticz sources, and now
temperature shows up with humidity only if they have
consecutive ID, otherwise they are shown separated.

@zampedro I have exactly the same problem

Could you please tell me more of how you modified Domoticz source?

This bug is really annoying!

@miljume Domoticz developers consider this a feature... not a bug ;-)

I get a similar problem on my plant monitoring. The graph always says "Temperature" even though the sensors only report humidity. I need to explain it every time I show the graphs to anyone.

[zampedro]

I modified MySensorBase.cpp

void MySensorsBase::SendSensor2Domoticz
case V_TEMP:

at lines 595 and 603 (numbers from last git code) for Temperature

// SendTempHumBaroSensorFloat(cNode, pChild->batValue, Temp, Humidity, Baro, nforecast, (!pChild->childName.empty()) ? pChild->childName : "TempHumBaro");
if ( (pChildHum->childID+1)== pChild->childID)
SendTempHumBaroSensorFloat(cNode, pChild->batValue, Temp, Humidity, Baro, nforecast, (!pChild->childName.empty()) ? pChild->childName : "TempHumBaro");
else
SendTempSensor(cNode, pChild->batValue, Temp, (!pChild->childName.empty()) ? pChild->childName : "Temp");

// SendTempHumSensor(cNode, pChild->batValue, Temp, Humidity, (!pChild->childName.empty()) ? pChild->childName : "TempHum");
if ( (pChildHum->childID+1)== pChild->childID)
SendTempHumSensor(cNode, pChild->batValue, Temp, Humidity, (!pChild->childName.empty()) ? pChild->childName : "TempHum");
else
SendTempSensor(cNode, pChild->batValue, Temp, (!pChild->childName.empty()) ? pChild->childName : "Temp");

case V_HUM:

at lines 678 and 686 for Humidity

// SendTempHumBaroSensorFloat(cNode, pChildTemp->batValue, Temp, Humidity, Baro, nforecast, (!pChild->childName.empty()) ? pChild->childName : "TempHumBaro");
if ( (pChild->childID+1)== pChildTemp->childID)
SendTempHumBaroSensorFloat(cNode, pChildTemp->batValue, Temp, Humidity, Baro, nforecast, (!pChild->childName.empty()) ? pChild->childName : "TempHumBaro");
else
SendHumiditySensor(cNode, pChild->batValue, Humidity, (!pChild->childName.empty()) ? pChild->childName : "Hum");

// SendTempHumSensor(cNode, pChildTemp->batValue, Temp, Humidity, (!pChild->childName.empty()) ? pChild->childName : "TempHum");
if ( (pChild->childID+1)== pChildTemp->childID)
SendTempHumSensor(cNode, pChildTemp->batValue, Temp, Humidity, (!pChild->childName.empty()) ? pChild->childName : "TempHum");
else
SendHumiditySensor(cNode, pChild->batValue, Humidity, (!pChild->childName.empty()) ? pChild->childName : "Hum");

In this way hum+temp of DHT11 are shown together ( CHILD_ID_HUM +1 == CHILD_ID_TEMP ) and
temperatures from ds18b20 are alone in separate widgets.

#define CHILD_ID_HUM 9 // DHT11
#define CHILD_ID_TEMP 10 // DHT11
#define DS18B20_STARTID 15 // DS18B20

@zampedro Sounds perfect, is there any chance this change can be merged into the source of Domoticz?

Where can I find the MySensorsBase.cpp? I am running domoticz on windows and in the installation folder I can't find the file. I can see the file on GitHub but how do I install domoticz from GitHub?

[zampedro]

@palande.vaibhav You have to compile domoticz from source, highly recommended if
you run it on raspberry, orangepi etc...

[AWI]

@zampedro Please have a look at this thread. The "combination issue" is discussed and solved. There is no reason to compile Domoticz yourself when running on Raspberry. I discourage compiling yourself (unless you like the excercise). The precompiled image works out of the box.

[zampedro]

@AWI Thanks for the hint.
I thought this wasn't a "issue" but just a "really annoying thing".
However i run domoticz on a Orange PI PC with WiringOP support and i can't find precompiled images.
