Hardware

I found the problem: https://github.com/LowPowerLab/SPIFlash/issues/16 The sketch I used to verify the SPI Flash was missing a SPI.begin() in setup().

@Takero Good idea, I will implement it ! Thanks !

Would there be much call for the current sensing capabilities on this board? Do people actually care for per module current sensing or would you just rather monitor your main electric board for overall usage?

I don't know what kind of html fritzing produces. But you can normally copy html tables into excel/openoffice and export a csv/xls from there.

can you post some code? interrupts work fine with my sonoff: attachInterrupt(PIN_PIR_SENSOR, ISR_PIRPinHasChanged, CHANGE); void ISR_PIRPinHasChanged(){ int currentPinStatus = digitalRead(PIN_PIR_SENSOR); if(currentPinStatus == LOW){ Serial.println("ISR fired, pin LOW"); } else{ Serial.println("ISR fired, pin HIGH"); ToggleRelay(); } } ISR fired, pin LOW ISR fired, pin HIGH toggling relay to OFF switching off sending status to controller ISR fired, pin LOW ISR fired, pin HIGH toggling relay to ON switching on sending status to controller ISR fired, pin LOW ISR fired, pin HIGH toggling relay to OFF switching off

@Igor-Antolić if you want to help the original author of the question, posting an answer on the linked stackexchange thread will probably be more efficient. The original author is not likely to look in a different forum, almost 5 years later.

@sbpurohit I assume it comes with everything (else it would defeat the point of the kit), but I would suggest you to email PCBway to have direct confirmation with them.

Ok thanks for your answer

Answering my own question: looks as though 1.02mm diameter should work fine.

@DavidZH - I really hate our electrical system here, but that is coming from an electronics guy, not a electrician. I like the idea of low voltage in the switches, however its AC. I would prefer to see DC, but the voltage drops might be something that they're attempting to avoid by sending AC instead. Yes, i agree about those damn rings and we also don't have the room here in the UK like you mentioned about the NL.

@boozz said in How to test/monitor packet loss for each radio node?: https://forum.mysensors.org/topic/3984/nrf24l01-connection-quality-meter Thanks, Ronald. I will definitely be putting together one of these very shortly. Looks handy for testing coverage and new radios. In addition to this approach, has anyone come up with a technique for monitoring all the nodes on an ongoing basis and flagging problems in real time? I greatly appreciate the value of the shared contributions on this forum! Thanks, Tim

Consider using the ethernet gateway if you keep having trouble with the serial one

No problem, I am running the nrf24 mqtt gateway on the rpi and it is working with no problem with domoticz. I choose the mqtt client gateway because I wanted to tinker around MQTT, but you could go for the ethernet gateway that is easier to manage.

Ok, thanks.

@AWI So I will Keep my batterys above 2.7 Volts ..:-) So in Summary... Hope its now correct Shorting the 3V3 Connections (right site of the Picture) plus from Battery to VBAT minus to any GND Any many many thanks for your Patience !!!!

@Lee-Groom - over time the community have found out that its best to power the radio directly from the batteries and not through the booster due to what @AWI said. Thats how i build my PCB. The nrf24l01+ can handle down to 1.9V so you have atleast a span of 1.9 - 3.3v to work with if you are using 2xAA. I would suggest powering your radio directle from battery and the rest throught the booster. Filter the booster with 0,1uF cheramic cap on the output (I dont know why, but learning by doing i have found this to work the best for me). Also be aware of that out of 10 china boosters i get atleast 2 that is so bad they generate so much noice its hard to get a good circiut.

@shabba As far as I can see (from search on mouser) there is no spi flashes available, which is capable at operating at 5V.. The closest is AT25XV021 / AT25XV041, which have an absolute maximum VCC of 4.4V http://www.mouser.dk/Semiconductors/Memory/Flash-Memory/_/N-488w1?P=1z0y176Z1yzmm0hZ1yzmm18
