Radio receiving signal

I have a relay and a motion sensor on the same node, and my sensors shows up in Domoticz as expected. Motion detection is also going through to the Domoticz, however I'm not able to receive incoming messages on the node to control the relay. It only works if I move the node closer to the controller.

So it seems like my radio is able to send messages, but are struggling when it comes to receiving. Can I do something on the sketch to improve that? My controller is using a NRF24L01+PA+LNA, while my sensor has a NRF24L01+

@andriej Hi, I had problem using the main branch mysensors/Raspberry, that because of the bit-field struct (header_s) in Sensor.h They will get packed in different order on the arduino compared to the RPi (at least with my compiler, gcc). In order to fix this I created the 1.4dev branch. It uses full bytes instead of the bit-fields, but you need (of cause) to compile both the sensors (arduino) and the gateway (RPi) using the 1.4dev branch. We need to fix this in the main branch later on (and use the same files as in mysensors/Arduino/libraries/MySensors)

@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);

It seems you can access the child ID from the sent message by looking at the destination property. If you have the message object, you can extract the ID directly from there.

Well, my network with two handfulls of nodes in three different locations is still live and kicking! I agree that there does not seem to be a lot happening in the community. I'm running 2.4.0- alpha since this gives support for MQTT over TLS. Just managed today to create one more MQTT GW after reading a lot about support for ESP8266. You know, these things you do once per year and have to learn new each time. MySensors is the cheapest way I have found to create small sensor nodes etc. But now slowly running out of my supply of hardware. Well, time will tell...

Old topic, I know. Did anything ever come of this? I'm also thinking it would be easy & cheap to get the espnow working as a transport layer. I found this: https://www.mysensors.org/apidocs-beta/classESPNOW.html But it goes above my head and abilities when it comes to code.
