    • RE: Power usage with a Pro Mini as sensor node(Humidity & Temperature!)

      @Magiske this is approximation. I'm using 2AA alkaline batteries. Full alkaline battery is 1,6Vx2 = 3.2V. When battery is discharged voltage at beginning drops very quickly, between 1.5V and 1V is almost linear (when discharged with low current) and then drops very quickly. At 0.8V per cell battery is practically empty.
      In my case 3V and more is 100% and 2V is 0%. I've measure those 2% in linear range. So I will get more than calculated value 2300 days.

      I'm using wasted alkaline batteries from electric toys. Batteries are not branded. Capacity of new AA battery is between 2200 mAh and 2900 mAh. It depends on brand and discharge current. Self discharge rate of alkaline batteries is low.

      Outside I'm using 50W photocell and Pb accumulator. It works in the winter (min -15C couple of days). This is also power supply for balcony irrigation system.

      Total winner in low power consumption is my water leak sensor. Power consumption is so low, that after I put wasted battery in sensor from LCD temperature display voltage actually raise after couple of days.
      Battery status:
      1.dec 8%,
      8,jan 18%.

      @m26872 here is my complete description for MySensors door/window sensor. For other sensors I will add descriptions in the future...

    • RE: MySensors power consumption

      @tbowmo I know for this Atmel limitation. But DHT22 sensor is open collector output and pull up resistor is connected to battery. It can happened that after battery voltage drops the sensor will stop working because of threshold value for 1 as you said. But as I said this was just experimental solution I will use HTU21T sensor.

      @funky81 Thx. You can burn fuses with other Arduino - that's how I do it. Just google ArduinoISP.

    • RE: EasyIoT serial interface

      @diamantmatch you are right. Maybe somehow I can change current driver to work with serial interface. But Raspberry costs only 30$ and consumes couple of W - ideal HW for server. And you do not even need additional gateway.
      Right now I will focus on developing other new functions...

      @aur did you check EasyIoT server installation. Just connect NRF24L01 directly to RPI and then download RPI image and put it to SD card. In latest beta you have also support for RPI2.

      @hawk_2050 Battery status is supported. You do not need to configure anything. Just send battery status and it will show in user interface.

    • RE: My 2AA battery sensor

      @daenny yes, I'm using DO pin and MOSFET connected to step up regulator. But this is complicated solution. I'ts better to use different temperature sensor which can operate down to 1.8V. Right now I'm testing custom board with NRF24L and HTU21D (it's not cheap, but it can work down to 1,8V). Results are pretty good. Temperature and humidity sensor can operate more than 5 years on 2 AA batteries. For example door window sensor and water leak sensor can work more than 10 years on 2 AA batteries. It's seems that for those sensors AA batteries are overkill.

    • RE: EasyIoT serial interface

      @diamantmatch EasyIoT server can work on Raspberry Pi and Windows platform, but on Win platform it does not support MySensors protocol. The reason is that on Raspberry Pi is NRF24l01 directly connected to GPIO ports. It means it depends on Raspberry Pi HW. Misleading text in controller description on MySensors site will be fixed in new update.
      By the way - direct NRF24L01 connection to GPIO works great, so why use gateway?
