Operational and debug MySensors network

carlierd 6 Mar 2016, 17:19 last edited by

Hello,

In order to continue node development I use two MySensors network. One operational and one for dev/debugging.
My networks are using RFM69 so the difference for both network is only on the variable RFM69_NETWORKID.

I am not sure (and don't want to test again) but each time my two gateways are switched one (on two computers) the operational network stopped working.

Is someone doing same thing ? Do you have issue ?

David.

@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)
No merge into master in the last 5 years, should we use development?

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...
Is it possible to extract child ID from a just sent message?

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.

Hey! If you're using ESP32 with LoRa (RFM95) and a Raspberry Pi gateway, here are some quick tips: Hardware: Heltec ESP32 + LoRa boards work great with MySensors. Power: ESP32 (~600mA) + LoRa (~120mA) can drain batteries fast—Arduino might be better. Software: Use Arduino IDE for ESP32 (try EnergyMeterPulseSensor), and set up an MQTT gateway on the RPi. Home Assistant works well for data visualization. Real-World Tips: MySensors + LoRa is great for farm/weather monitoring—checking similar projects can help.

When connecting an accelerometer to your PC, consider its communication protocol (I2C or SPI) and the appropriate interface device, like a microcontroller (e.g., Arduino). You may also need additional hardware for voltage adjustment or signal conditioning, depending on the sensor’s specifications.

@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);
