I don't have a home controller. The sensor network and the gateway are enough for me if
I could place the humidity control and an html server on the gateway.
my sensors: arduino pro mini, rf24, and humidity sensor. unfortunately I can't find an entry point on how to extract the humidity values, for example, for processing.
Maybe someone can give me a tip? Best with an example.

Hello here is why it does not compile as you want, the library must be MySensors 1.5.4 I tested today the compilation. that's why include<MySensor.h> and not MySensors.h I wish you a good day with my cordial greetings

Hello all, First things first - this is a great device, kudos to everybody involved! I built a buggy nrf24Doctor - it wasn't measuring the current consumption at all ("xxx Err" message). Trying to fix it led me to refactor the - splitting it into smaller "components" and adapting the project structure to VSCode/platform-io (ArduinoIDE is not my cup of tea). If someone is interested, the code can be found at github. Regards, L.

@henkoegema said in TinyBME - ATTiny85 + NRF24l01 + BME280/I2C: @Wim-Oosterhof said in TinyBME - ATTiny85 + NRF24l01 + BME280/I2C: I was attracted to the idea of having a wireless hum/temp sensor and so I built this. I prototyped it on a breadboard, and I also soldered it on a PCB. I extended the antenna with a 8.3 cm wire. But I can't get it to work stable. Sometimes it works for many hours and sometimes only for one hour. And then it just hangs. A reset of the at85 sometimes helps, but most of the times I need to power it off and on again. I need it to work reliably for several weeks. Any suggestions ? Have you got any suggestions? Did you get it to work stable? Or have you abandoned the project?

@patrick-schaerer can I use same code file for measuring current only using sct-013-030 and at other end I'll use other sensor to read ac voltage and with the help of that I'll calculate power. I'm new on this. Just start learning and I'm using esp32 instead of Arduino. Please share your suggestion on this. It will really help me to learn .

Hi @nagelc , thanks for coming back to me - Apologies I didn't realise you'd replied nearer the time. Am I right in thinking, so long as I define the new patterns function later on in the sketch - I can include it in the switch of function updateLightPattern, and it will be added to the mapping? How do we know what definitive figures the 0 to 100 percentage map to in 0 to 15? Or is that basic arithmetic and each switch state will be called in each 'chunk'. I also only count 10 items in the switch state. Does that mean we can add 5 more? and if wanting more than 15 simply change our mapping size to have more? Appreciate the help. void updateLightPattern(){ // global: curPattern, updatePatternDelay, lastPatternUpdate unsigned long now = millis() ; if (now > lastPatternUpdate + updatePatternDelay){ // check if time for update switch (curPattern) { case pAlarm: // flash light patternAlarm(); break ; case pFire: // wild fire patternFire(); break ; case pFire2: // cosy fire patternFire2(); break ; case pCandle: // flame patternCandle(); break ; case pCircle: // flame patternCircle(); break ; case pRainbow: // rotating rainbow patternRainbow(); break ; case pSinelon: // rotating rainbow patternSinelon(); break ; case pSolid: // do nothing fall through case pOff: case pOn: default : // def break ; } lastPatternUpdate = now ; } }

@bach e01-ml01sp4 is just a wireless module produced by EBYTE based on NRF24 plus PA/LNA chip to improve the signal. If you take off the metal lid you will see Nordic's chips there. Operating voltage means power supply, VCC pin. Digital IO of NRF24 is 5V tolerate. But you do you. @bach said in nano & E01-ML01SP4 gateway: i can't explain it as i don't fully understand it, i followed this tutorial https://maker.pro/arduino/projects/how-to-use-ams1117 Well, someone have misunderstood something, I guess. Any explanation for a resistor between GND pin and ground is if it is adjustable version of this regulator. And even then it would be used with resistor divider, not just one resistor. @bach said in nano & E01-ML01SP4 gateway: and where would you put the 0.1uF ? on the output of ams1117 or in the input of nrf24 ? Next to the cap you are using for NRF24. All caps work together, but for ensuring the best performance you need to place capacitor as close to actual VCC pin of the chip as possible. In your case it's not possible, because you are using prefabricated module, but you get the idea. @OldSurferDude said in nano & E01-ML01SP4 gateway: I believe that what @monte is saying that there will probably be little future support for the nRF24 at MySensors. No. I am saying that current development of MySensors is basically stalled. And I am not sure if anyone is seriously interested in keeping this project updated. @OldSurferDude said in nano & E01-ML01SP4 gateway: @monte is saying to use both capacitors 4.7μF electrolytic and 0.1μF ceramic. No. The practice of using smaller capacitor in parallel with the bigger one is not limited to only electrolytic ones. Please read this answer: https://electronics.stackexchange.com/questions/298798/capacitor-placement In this particular case it won't make much difference if any. But it's a good rule to remember if you are planning on making more complex circuits in the future. I may be wrong about IRQ pin after all. It seems to be used with MY_RX_MESSAGE_BUFFER_FEATURE feature. But I see that some people report problems using it and it only works with AVR.
