Upgraded my home sensor network to 2.1.1...

I upgraded my home sensor network to MySensors 2.1.1 last week.

Prior to that I was having connectivity issues....I would lose nodes from the network fairly regularly.

I'm happy to say that 2.1.1 resolved all those issues and everything looks rock solid now. Haven't dropped a node since. Yay!

Would have been nice to know about the change in startup sequence for 2.1.1 (new before() method), but other than that, a very solid release.

Well done!

@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);

@CodeGarage What I want is a lion powered Sensor if possible. And that in a case I can stick to the door frame. As I cannot screw or drill into the doorframe. But I have no idea how much current that draws.

It looks like duplicate email notifications may be linked to system settings or preferences. Have you noticed if the issue happens after specific actions or changes? Investigating your notification settings might shed some light

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...
