Damm I am trying to get this working with a Arduino pro mini ,,but no luck wanted to use it in the car ..
How do you wire the NRF24L01+ ???
N-Channel Mosfet s ??? model number please any help much appreciated
I have tried mosfets >>>irf510n
Hello, i'm making some progress; received the components this week.
Unfortunately it doesn't work... yet
For now i have SanityCheck failure in to logs.
I'm afraid my soldering of all these little components is not good. I tested with a multimeter the 4 pins and i have continuity on one of them but maybe not the others so i guess i will have to try remelting all these small regulators ???
I am non technical but I have 8 wirsbo stats in my house. One of them is faulty and the unit is now obsolete. Is it possible to purchase one of these pcbs and use it to replace the one in the faulty stat ?
Thanks
Richard
I have published all the documentation in a Github repository. If someone wants to make PCBs, I recommend that you wait a little longer until you receive my PCBs and try them.

@ZenBlizzard in case you are measuring the output with a multimeter, you will get an averaged level, since AC current waveform should be sinusoidal and overlapped with the Vcc/2->2.56V in your case.
To measure the current you need a decently high sampling and some math.
#define SENSITIVITY 66 // mV/A
const float readings = 5;
const float alpha = 2.0 / (2 * readings + 1);
for (ifor = 0; ifor < 250; ifor++)
{
// Voltage
voltageSampleRead = analogRead(V) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/
voltageSampleSum = voltageSampleSum + sq(voltageSampleRead); /* accumulate total analog values for each sample readings*/
voltageSampleOffsetSum = voltageSampleOffsetSum + voltageSampleRead;
// Current
currentSampleRead = analogRead(I) * vccRead / 1023 - vccRead / 2; /* read the sample value including offset value*/
currentSampleSum = currentSampleSum + currentSampleRead * currentSampleRead; /* accumulate total analog values for each sample readings*/
currentSampleOffsetSum = currentSampleOffsetSum + currentSampleRead;
wait(1);
}
voltageMean = voltageSampleSum / ifor; /* calculate average value of all sample readings taken*/
voltageOffset = voltageSampleOffsetSum / ifor;
reading = (sqrt(voltageMean) - voltageOffset) * 230.0 / 1.0; // read voltage / reported voltage.
voltage = round_to_dp(alpha * reading + (1 - alpha) * voltage,1);
Serial.println(voltage);
if (voltage < 25) voltage = 0;
currentMean = currentSampleSum / ifor; /* calculate average value of all sample readings taken*/
currentOffset = currentSampleOffsetSum / ifor;
reading = (sqrt(currentMean) - currentOffset) / SENSITIVITY * 1000 - currentZeroOffset; // subtract no load current.
if (reading < 0) reading = 0;
current = round_to_dp( alpha * reading + (1 - alpha) * current,2);
