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.

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.

It seems the ACS712 current measurement module may not show expected changes due to setup issues, like incorrect wiring or misunderstanding of signal interpretation. Checking if you're measuring the right type of current (AC vs. DC) and ensuring your connections are correct can often resolve this.

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

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.

It seems like you're exploring the use of PJON with RS485. While RS485 is natively supported in MySensors, using PJON for collision handling can offer some interesting advantages, especially in environments where communication reliability is critical. PJON's collision management may be useful in bus systems like RS485, but it's worth considering whether the added complexity is necessary.

It seems that using an Ethernet PHY (like LAN8720) with the ESP32 in a MySensors setup requires a bit of extra configuration, including initializing the PHY using the ETH.h library and disabling the default Wi-Fi initialization. Interestingly, this setup allows for dual IP addresses, with one for the Ethernet connection and another for Wi-Fi, which can be useful in certain applications.
