Finally bottomed out the issues on this. Radios purchased from ebay were sub standard quality. Purchased some that had the proper IC and components on the board. Plugged in and worked straight away. Thank you for all your assistance.

Thanks very much for that pointer. You have been very helpful. All working now.

To the person that commented on the build instructions. Check your wiring. I now have it working on 2.1 library with no code changes.

I have built an Mqtt gateway as you suggested. from the arduino serial monitor I can see it working, as below.

I have mosquitto broker running on my pi 3. Node-red shows connected to the mqqt broker, yet no data is shown passing.

any ideas how best to fault find this issue

@gohan I am just thinking about the implications of moving to mqqt. This will break my home assistant setup. I also have over 30 sensors I would have to change the setup of.

If you see this as an example, "67;0;1;0;0;62.5↵" which is my data from a sensor showing in node-red debug. The 67 is the nodeId, the next 0 is the childSensor Id and the 62.5 is the temperature.

This the code I am using in a function of node-red to try and extract the temp value.
if (msg.payload.nodeId == 67 && msg.payload.childSensorId === 0) {
var msg;
msg.payload = msg.payload.value;
msg.topic = "Temperature";
return msg;
}

Can anyone spot any reason why this may not work ?

@gohan Ok, thanks for the advise. Strange that I can't use what I have, especially seeing as I can see the data coming from the sensors in node-red.

@gohan Hi, Can you give me some pointers on what I need to do to change to MQQT Gateway. I am not overly sure on the difference.

@gohan Ethernet gateway. As you can see above I have data. Just can't seem to extract the temp value for each sensor to make it usable for a gauge and graph

Hi
Yes I have. They just seem to to reformat the whole data. I just want to extract the temp value from each sensor to display in a gauge and a graph.

Hi All

I am having a go with Node-red. I have several temp sensors which I know are working as they are on home assistant. I know I am getting the values into Node-red using the debug.

This is an example of the info coming in.

So I want to separate the information so that I can show a gauge and graph and use in a thermostat. so nodeId 67 childSensorId 0 is a sensor I want the value for, and also nodeId 67 childSensorId 5. I have tried with this script in a function, but it does not output anything.

if (msg.payload.nodeId == 67 && msg.payload.childSensorId === 0) {
var msg;
msg.payload = msg.payload.value;
msg.topic = "Temperature";
return msg;
}

Could someone point me in the right direction to what i am doing wrong.

Instead of showing values it showed nan.

The node was connecting to the gateway, but no sensor values were available to send.

On the example sketch the sensor showed values without issue.

Thanks for the rely. Yes sorry for the sketchy info.

When using the mysensors sketch and looking at the serial info, no values from the sensor were being reported. At first I thought it maybe the sensors being faulty. So I thought I would just test the sensors on their own to make sure it was not hardware. When using the example sketch the sensors outputs temp and humidity, but not on the mysensors sketch.

Thanks for your help, Laurie
