Hello together,

I'm just trying to get the voltage measurement to work. But there is something wrong. I built everything as shown above and uploaded the program to the Arduino pro mini. The only thing I changed is the sensing Pin A0 -> A3
In debug mode I see the following (the supply voltage is constant 3.3V):

Battery Voltage: 3.12 V
Battery percent: 92 %

Battery Voltage: 2.40 V
Battery percent: 71 %

Battery Voltage: 2.32 V
Battery percent: 69 %

Battery Voltage: 2.31 V
Battery percent: 68 %

Battery Voltage: 2.29 V
Battery percent: 68 %

Battery Voltage: 2.30 V
Battery percent: 68 %

Battery Voltage: 2.33 V
Battery percent: 69 %

What could be the reason? That doesn't make sense to me.

hey @tbowmo

I found my mistake in /home/openhabian/.npm/_logs
I had to use sudo ....

But I have another Question. Do I need an Arduino in-between or can I connect the modul directly to the Raspberry pi like it is done here.

Thank you very much for your help!!

Hey @rozpruwacz

there is no binding for mysensor in openhab 2.3 available at the moment (my 3. post). Or am I wrong?

Sorry can you please give me a smal step by step introduction? Where do i have to install what?

Thanks. But the installation does not work. Firstly, I installed Node-Red and then the npm. Afterwards I tried to install node-red-contrib-mysensors.

Hi,
great work. I tried to install it, without success. First I installed node-red und npm. As operation system I use openHABian v1.4.1.

This is the output:

npm install node-red-contrib-mysensors

Hey,
I am a little bit helpless. I installed Openhab 2.3 and there is no Binding for mySensors. After some research I found out, that this Binding is still in progress.

There is still another possibility by using the W5100 MQTT gateway. Do I have to use a ESP or Arduino for this? I connected the RFM69 modul directly to the raspberry pi to avoid this aditional step. How can I use the MQTT Gateway?

@mfalkvidd Okay thanks!

Hello everyone,
I want to build up a sensor network basing on mySensor. The good thing at the beginning: I am able to send sensor data from one to another Arduino and can read the Data via Serial port. So far so good

Now I want to integrate the sensors to openhab2 by using mqtt. I have a simple (maybe silly) question about this. How do I have to connect my RFM 69 modul to my Raspberry pi? Do I need an Arduino in-between or can I connect the modul directly to the Raspberry pi like it is done here (wiring Mqtt rfm69)?

Tanks for Helping !
