Thanks for that, yes I noticed your thread somewhere and I was delighted to see gizmocuz working on your issue. Unfortunately the changes made broke my workaround hack. It just means I need to look for a more conventional solution that does not include modifying cpp files.
What I will do is re-code my mysensor nodes to use other variables such as V_WATTS etc rather than V_VAR1, VAR2 etc.
OK, yes you are right looks like S_CUSTOM values are not supported.
So for those of you who are brave enough to make your own Custom MySensors nodes read on...
I wish there was an easy way to add your own custom sensor, as I need to make many of them.
pH Electrical Conductivity(EC), Tank Water Volume (Liters), UVa and UVb in mW/cm2 ioniziing radiation in uSv to name a few of my sensor devices.
But right now I need to get my kWh import/export transmitter recognized by Domoticz.
So I guess I will just have to find a work around as Domoticz looks quite good stacked up against other free controllers.
Here is what I have done so far...
I have discovered you can hack the hardware/MySensorsBase.cpp file. This is a really crude hack but I admit I am no C expert. Maybe someone can point out a better way of doing this.
I am running Debian Lime on and Olimex A10.
You will need the Source files, so if running on a RasberryPi you cannot use the compiled binaries, you will need to download the source code from github.
Compile your domoticz and get it running first. If you do not want to run Domoticz as root then make sure you don't compile as root as you'll have to start all over again, downloading from github. A trap I fell into.
Also you need to uninstall the boost libraries and get the latest one. Doing the sudo apt-get update and then sudo apt-get upgrade doesn't seem to get the correct boost libraries.
Google how to remove current boost and how to install latest ver.
On with the task... Here are the values I am sending in my sketch:
imported energy (CHILD_ID_0, V_VAR1);
real power (CHILD_ID_0, V_VAR2);
apparent power (CHILD_ID_0, V_VAR3);
voltage (CHILD_ID_0, V_VAR4);
current (CHILD_ID_0, V_VAR5);
freq (CHILD_ID_1, V_VAR1);
peak power CHILD_ID_1, V_VAR2);
pf (CHILD_ID_1, V_VAR3);
exported energy (CHILD_ID_1, V_VAR4);
By trial and error I found there are 4 places you need to edit inside MySensorsBase.cpp
Find the line starting case S_CUSTOM:
and modify as below
case S_CUSTOM:
vType = V_VAR5;
bDoAdd = true;
break;
Find line starting : case V_CURRENT:
Then add the V_VAR1 through V_VAR5 variables that you are using
case V_CURRENT:
if (pChild->GetValue(vType, floatValue))
SendCurrentSensor(cNode, pChild->batValue, floatValue, 0, 0, (!pChild->childName.empty()) ? pChild->childName : "Current");
break;
case V_VAR1:
if (pChild->GetValue(vType, floatValue))
{
if (pChild->childID == 0)
SendKwhMeter(pChild->nodeID, 10, pChild->batValue, 0, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Imported Energy");
else
SendCustomSensor(11, 11, pChild->batValue, floatValue, ("Hz") ? pChild->childName : "Line Frequency", "Hz");
}
break;
case V_VAR2:
if (pChild->GetValue(vType, floatValue))
{
if (pChild->childID == 0)
SendWattMeter(cNode, 20, pChild->batValue, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Real Power");
else
SendWattMeter(cNode, 21, pChild->batValue, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Peak VA");
}
break;
case V_VAR3:
if (pChild->GetValue(vType, floatValue))
{
if (pChild->childID == 0)
SendWattMeter(cNode, 30, pChild->batValue, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Apparent Power");
else
SendCustomSensor(31, 31, pChild->batValue, floatValue, ("pf") ? pChild->childName : "Power Factor", " ");
}
break;
case V_VAR4:
if (pChild->GetValue(vType, floatValue))
{
if (pChild->childID == 0)
SendVoltageSensor(cNode, 40, pChild->batValue, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Supply Voltage");
else
SendKwhMeter(pChild->nodeID, 41, pChild->batValue, 0, floatValue, (!pChild->childName.empty()) ? pChild->childName : "Exported Energy");
}
break;
case V_VAR5:
if (pChild->GetValue(vType, floatValue))
SendCurrentSensor(cNode, pChild->batValue, floatValue, 0, 0, (!pChild->childName.empty()) ? pChild->childName : "Current");
break;
Next find the section: starting: case V_VAR1: //Custom value
Change as below:
case V_VAR1: //Custom value
case V_VAR2:
case V_VAR3:
case V_VAR4:
case V_VAR5:
pChild->SetValue(vType, (float)atof(payload.c_str()));
bHaveValue = true;
break;
Find this section: case V_VAR1:
And change as below
case V_VAR1:
case V_VAR2:
case V_VAR3:
case V_VAR4:
case V_VAR5:
//send back a previous stored custom variable
tmpstr = "";
GetVar(node_id, child_sensor_id, sub_type, tmpstr);
SendNodeCommand(node_id, child_sensor_id, message_type, sub_type, tmpstr);
break;
After making changes to the file you must run "make" again to compile domoticz binary.
It is a lot faster to "make" subsequent times.
cmake -DCMAKE_BUILD_TYPE=Release -modified .
makeMore reading on the Forums seems to point to a need to edit MySensorsBase.cpp
Not looking forward to that!
But if there is documentation how to customize MySensorsBase.cpp file I will have a go!
Here are the relevant parts of my custom Sketch:
It is an Import/Export Utility meter.

I have a node with S_CUSTOM V_VAR1, V_VAR2 which is not appearing in Domoticz.
Domoticz Version is 3.4944
I am compiling Serial Gateway on Development train
Sensor Node is on Development train (my sketch needs a lot of RAM).
Nodes and Children show up but not the values.
I just compiled the Gateway in the 1.4.2 Mysensors bundle. I compiled a LUX node and a Pressure node, but still no luck, I always get the nodes showing up as Node 254 and overwriting each other.
So seems my issue may not related to the Gateway Version.
Not concerned with bugs in the UV Sketch as I will make my own sketches once I get the controller to recognize the nodes.
My plan is to adapt some code to make tank level sensors and an analog (not pulse based) kWh meter. Also planning to control some pumps, so those will be outputs.
So should I use Arduino 1.4.2 for compiling code for Gateway and all the nodes, yes?
Aha! I thought it might have been a gateway issue. Yes of course I am running ver 1.5 so I will try v1.4.2 and report back how it goes!
In the meantime here are my configs.
I have loaded the UV node information into Fhem but it still will not recognize the node.

I will try. I did Google searches but mostly answers are in German.
I still can't work this out. If i turn on inclusion-mode on the serial gateway I always get NODE ID 254 assigned. And if I add a second node it shares the same node id and I end up with attributes for many sensor type all in the same node. It lways gets named MYSENSOR_254. Pulling my hair out for 5 days now... can anyone help?
I have an 8MHz 3.3V Pro Mini Arduino with a NRF24l01 connected to a Olimex A10 (Debian Lime). I have set the Serial gateway to run at 57600 and also created a gateway in Fhem.
/dev/ttyUSB0@57600 with auotocreate set to 1 and requestAck set to 1.
I ran all the Fhem updates.
I have a simple Battery Monitor Node with no Sensor IDs just the battery level. But I cannot see the battery level in the log.
I only get this message:
2016.02.11 10:51:53 3: MYSENSORS: ignoring internal-msg from unknown radioId 254, childId 255 for I_BATTERY_LEVEL
Isn't Fhem supposed to Auto Add Nodes? What am I doing wrong?
