Send an array of ADC data

Vasilis Vlachoudis last edited by

In my home automation (with mysensors + home assistant) I am monitoring the 3 phases of the house with CT current sensors and the emonlib, which works nicely.
I wanted from time to time to send a full waveform with mysensors, but I could not find out how to send an array of readings instead of a single entry. Is it possible to do it with mysensors?

I want to experiment making an AI to identify from the waveform the device that is consuming the power.

@Knightan I believe that your problem may be related to this block of code. See my thoughts as comments.... if (message.type == V_STATUS) { //This is true for all messages received // Change relay state state_1 = message.getBool(); //This sets state for state_1 to the received value. digitalWrite(LED_PIN_Channel_1, state_1?RELAY_1_ON:RELAY_1_OFF); // Store state in eeprom saveState(CHILD_ID_5, state_1); // Write some debug info Serial.print("Incoming change for sensor: STATE 1"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } if (message.type == V_STATUS) { // Change relay state state_2 = message.getBool(); //This sets state for state_2 to the received value. digitalWrite(LED_PIN_Channel_2, state_2?RELAY_2_ON:RELAY_2_OFF); // Store state in eeprom saveState(CHILD_ID_6, state_2); // Write some debug info Serial.print("Incoming change for sensor: STATE 2"); Serial.print(message.sensor); Serial.print(", New status: "); Serial.println(message.getBool()); } It seems to me that state_1 = message.getBool(); AND state_2 = message.getBool(). So they both get set to the incoming value. I think you need to not set both to the same value and instead differentiate them to unique values. I could be wrong as I have not had chance to do anything related to mysensors for a long time now - I also don't use Domoticz. Have a look at the code on this page, it might help you a lot.... https://www.mysensors.org/build/relay
Does MySensors require Arduino Timer 2?

I have success! (oops, that's suppose to be Timer1) I only sample for 1/60 of a second. What I did was to back up all the timer registered I used and then resorted them after I was done sampling. (As opposed to initializing the registers in setup and then starting the timer when needed.) Now I have a Nano sampling the data and sending it to a MySensors Gateway on an RPi3B+ which then sends it to an MQTT broker runing on an old laptop. Also running on the laptop is Home Assistant running inside of VirtualBox. If MySensors does use Timer1, it appears that restoring the registers allows it to be shared. //------------------------------------------------------ISR ISR(TIMER1_OVF_vect){ // interrupt service routine for overflow TCNT1 = TimerPreloadValue; // must be first line! starts the timer counting again digitalWrite(TRIGGER_START_SAMPLE_PIN,HIGH); samplesVolts[--sample]=analogRead(VOLTS_IN_PIN); // decrement before capturing samplesCurrent[sample]=analogRead(CURRENT_IN_PIN); digitalWrite(TRIGGER_START_SAMPLE_PIN,LOW); if (!sample){ // count down to zero digitalWrite(TRIGGER_START_SAMPLE_PERIOD_PIN,LOW); // indicate that sampling is complete samplingEnd = micros(); TCCR1B &= 248; // turns off timer } } //------------------------------------------------------sampleOneCycle void sampleOneCycle(){ // back up timer registers uint8_t TCNT1_b = TCNT1; uint8_t TCCR1B_b = TCCR1B; uint8_t TCCR1A_b = TCCR1A; uint8_t TIMSK1_b = TIMSK1; // configure timer which starts the sampling noInterrupts(); // disable all interrupts TCCR1A = 0; TCCR1B = 0; TCNT1 = TimerPreloadValue; // preload timer //TCCR1B |= (1 << CS10)|(1 << CS12); // 1024 prescaler TCCR1B &= 248; // turns off timer? TIMSK1 |= (1 << TOIE1); // enable timer overflow interrupt ISR // demark sampling sample = NUMBER_OF_SAMPLES; // count down to zero digitalWrite(TRIGGER_START_SAMPLE_PERIOD_PIN,HIGH); samplingStart = micros(); TCNT1 = 65535; // first trigger right away! TCCR1B |= 1; // turns on timer interrupts(); // enable all interrupts // wait for sampling to be complete while(digitalRead(TRIGGER_START_SAMPLE_PERIOD_PIN)){}; samplingEnd = micros(); // restore timer registers TCNT1 = TCNT1_b; TCCR1B = TCCR1B_b; TCCR1A = TCCR1A_b; TIMSK1 = TIMSK1_b; }

@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
