@Nca78 FWIW, I used 1.55mm holes. There may be no perfect diameter since we don't even know for sure yet which lens will turn out best.

@toyman said in NModule DC Fan / PWM shield: Can the FET withstand continious 2A load? I have one meter long 5050 strip FDD8447L is rated for 15A continuous load. You don't want to try that because it's possible only with a big pad and 2oz copper PCB, but 2A will not be a problem on this board, there's plenty of margin https://isojed.nl/blog/wp-content/uploads/2013/06/FDD8447L.pdf

What are the parameters of this radio, I could not get it to work. Suspicions that he had no speed 250.

@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);

@ricardot said in pimatic-mysensors controller plugin: @Dheeraj, Do you plan to continue to develop this plugin? I will very pleased to see a mysensors button. Thank you! I second this. And also see if we can lose the dependency on serialport 2.0.6 so that we can use Node.js > 4.9.1

Very useful topic for me, thanks. Even though it's been a long time, the information was useful to me. And especially the information on the link you sent.

@GLAB No worries, was in a similar situation.. My perspective was on what the Node could be made to provide, not what could be done within Domoticz to address the requirement - eg Had heard of Dummy counters but had no experience nor understood their purpose, nor had ever used scripts. I had been sending a logical ON/OFF as well as a cumulative total from the Node and hit the same hair-pulling scenario as yourself. Now only the ON/OFF is sent and the short script makes the transposition within Domoticz to a dummy meter (I think kWhr) using the internal clock in Domoticz. Have fun

@yoshi824 Most of us have been where you are now! I suggest that you try to see the patterns in the code that you have working and try to make the SHT30 work from what you learn. If it does not work as you want then post here the full code you have and what it is/isn't doing and you should get some help.
