Anyone Tried SEEED LORA-E5 Module?

I'm wondering if anyone has experience with the SEEED LORA-E5 Module, or the STM32WLE5JC.

It is an interesting looking module:

https://www.seeedstudio.com/LoRa-E5-Wireless-Module-Tape-Reel-p-5302.html

It has STM32WLE5JC, ARM Cortex-M4 and SX126x embedded and is aimed at IOT. Arduino has a Generic STM32WLE5JC board type. Seems like this combo might not be too difficult to slot into MySensors using the RFM95 libraries.

It would be nice to have a sub-gHZ radio and processor in the same module,

@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)

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.

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.

@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);

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.
