Looks great !

Have you measured what the minimum load is for the dimmer to function correctly ? I currently use X10 in wall modules but run in to trouble when switching to LED lights. The load is too small.

No i have not tested any minimum loads at the moment, this is one of the next steps

Hello, nice project!
does your system may work without neutral wire ?

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.

I see a lot of "!TSF" and "NACK" which seems to be radio communication problems. That's MySensors related and can be related to many things, from soldering problem to power / capacitor issues. In MY_DEBUG mode you should see your temp/hum printed on serial every ~15s so there is something wrong there, either wiring or a code issue. Ty with the example included with the library "i2c_SI7021.h", without any MySensors related stuff, to see if your sensor is detected. You should see temp/hum on the serial.

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; }

Added sketch, which also supports an additional mini PIR sensor. It's what I needed, you can comment to #define out. Also changed the regulator to a smaller one, which supplies up to 100 milli Amp, which is plenty enough. That way I can keep the circuit smaller on the PCB. Which allows me to create a smaller housing.

Hello. Any news from this project? Do you made the changes for the timer TLP?

@dzungpham0703 I replied in the nrf51822 thread. Yes I managed to make it work like the original with BLE stack. And using the wonderful Cypress Proc BLE solution including capsense and lots of goodies . Cypress really rocks! I love them. The current consumption was lowered to 200uA without being connected and 700uA connected. Those numbers include LEDs current consumption and other blocks like touch sensing. I'll get back with more updates when it's finished.
