    • Simple deep discharge protection for battery operated sensors?

      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 🙂

    • RE: 💬 Battery Powered Sensors

      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.

    • RE: node-red-contrib-mysensors release thread

      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!! 🙂

    • RE: How to connect RFM69 to Raspberry (Mqtt + Openhab2.0)

      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:

    • RE: How to connect RFM69 to Raspberry (Mqtt + Openhab2.0)

      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?
