Is it possible to drive a tinyTX wit a BEM280 sensor with I2C wiring? Has anybody already tried it?

Nathan's work inspired me for many years, so I am going to release an updated version of TinyTX4 over this year:

Hi Nathan Chantrell,
First of all thank you for sharing your experience
I made reference to TinyTX_nRF24L01_DS18B20.ino, and want to try to replicate the same situation
But I encountered at compile time error
I have tried to install the following library is still the same
DallasTemperature
mirf85
Narcoleptic
OneWire
RF24
SPI85
maybe I have missed what place?
Could you please help me? Thank you

digitalWrite(ONE_WIRE_GND, LOW); // set GND pin low <-------Verify error messages stay in this line

Set the reed pin from falling to rising
Set pin as input.
Connect the reed to vcc instead of ground and put a 1M resistor between pin and ground.
In your case I see a 100uA consumption on close state. In my case the consumption is dropping around 4uA.

Hi Nathan,

I'm still new with github and not sure how to pull to your repo - but I have found a minor error in your/my code (TinyTX_LDR_Meter.ino), which produces an error if less than 1000 (in this case) millis since last blink.

...
    } else if (interval > 1000) { // 1+ sec passed
        // Blinks are 1000 per kWh, or 1 Wh each
        // One hour has 3.6M milliseconds
        watts = nBlinks * 1 * 3.6E6 / interval;

        last = time;
        nBlinks = 0;
    }

  tinytx.power = watts; // Get realtime power

  tinytx.supplyV = readVcc(); // Get supply voltage

  rfwrite(); // Send data via RF    

    }

}

Needs to be changed to:

...
    } else if (interval > 1000) { // 1+ sec passed
        // Blinks are 1000 per kWh, or 1 Wh each
        // One hour has 3.6M milliseconds
        watts = nBlinks * 1 * 3.6E6 / interval;

        last = time;
        nBlinks = 0;

  tinytx.power = watts; // Get realtime power

  tinytx.supplyV = readVcc(); // Get supply voltage

  rfwrite(); // Send data via RF    

      }

    }

}

Kind regards,
Troels

Hello there!

I have downloaded all requirements from TinyTX tutorial page and I can write bootloader with no problems.
When I try to write dht22.ino I get an error:

'Sleepy' has not been declared.

I've tried to copy the includes (DHT22.h and JeeLib.h) in the sketch folder but the error remains the same.

What am I doing wrong?
