New to electronics and progamming.... hence excuse rather dumb nature of my query .. recently purchase the Devduino V2.2 OTA version and am trying to figure out if the device comes pre loaded with the arduino bootloader. ??

@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);

@HouseIOT Sorry to trouble you, i use a mysensors-wifi-gateway with protocol 2.1.1 , and my homeautomation is home-assistant. I can't use your dimmer in my system. After read the reference, there need to add V-percentage and V-status in the code, as a newbie , I can't do it myself. So I wondered，can you do me a favor? Thanks a lot.

@TON-RIJNAARD You need to select the board based on the bootloader you have flashed. Complile the code in Arduino and try burning the hex file using a programmer (USBasp, AVRISP, etc..) if are facing issues with Arduino.

Hi @talhatec , The remote controls work well. 4 months ago I installed a new battery and from time to time I press the button to check if they continue with battery, they sleep correctly. I remain pending to change the RF antenna for a better one and to improve some failures in the connectors of the battery that at the moment are very fragile (the pad has little copper). The casing can be purchased online https://www.ebay.com/itm/Bluetooth-4-0-GPS-Tracker-Locator-Smart-Alarm-Anti-lost-Device-Self-Portrait-SC/401394156488 For now the project is stopped, I want to test the Aqara sensors (I buy them this week), in any case the domotics is now my lowest priority.
