Hello everybody,
I have a few mobile battery powered Ardruinos to measure the temperature. These are powered by 3 AA batteries. But always one of the three batteries is deeply discharged (0V!). To avoid this in the future, I wanted to ask if someone knows a simple circuit that prevents this? If it is possible, this circuit should not require much power.
Hope I am here in the right area of the forum 
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?
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 !
@bgunnarb
You are right. I had to define a sensor id and now it works perfectly Thank you very much!
Oh. I am using the sketch in from above and only changed the radio module.
Hi
thanks for reply. I am using this sketch: https://github.com/mysensors/MySensors/blob/development/examples/GatewaySerial/GatewaySerial.ino
The only thing I changed is the radio type and I disabled the inclusion mode.
Hi
this program doesn’t work with my setup. For the Gateway I am using a Ardunio nano as a serial Gateway. Thus, I am using the GatewaySerial.ino. Even the Node is based on an Arduino nano with a DHT22 connected. The general communication between both seems to work. But I do not receive any sensor data. When testing the setup with another library for the dht sensor, it works fine (without sending to the gateway, only serial Monitor). Because I am new in the mysensors community there is perhaps a simple mistake which I don’t see… I hope you can help me finding my mistake.
Here is a short extract of the Debugging Information’s. As far as I see there are no data transferred.
