Re: d-diot: dual MySensors gateway for Raspberry... And more!

Hi guys,

the d-diot board v.2.0 is ready.
Respect to the previous version it is mechanically compatible with the new Raspberry Pi 4, and of course backward compatible with the previous version of the Pi.

The position of some components has also been changed (led mostly) to facilitate the development and to improve the design of the 3d printable case.

In this moment the compatibility with the Pi 4 is only mechanical because, if I'm not wrong, MySensors is not yet available for the new version of the Pi.

There are some other problems (LIRC for example) related to the adoption of Raspbian buster, so it is too early for a complete migration to the new hardware

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

Wow @Nicklas-Starkel congrats, that sounds great! And thanks for the feedback. Would you mind sharing your setup? Regards, Edi

@Paul-Scarbro There are multitude of solution, but since we are in MySensors Land, let's do a MySensors solution. You'll quickly see that doing that adds a lot of overhead. We'll use an Arduino Nano or RF Nano if you're going to go whole hog. It can be run from 3.3V or 5V DC, not AC. The reed switch would be connected to an input of the Nano and one of the outputs would drive a relay. The relay would drive the chime. Your C++ program would be something like: #define inputButton 2; // connect reed switch here #define outputRelay 4; // connect relay to this pin see MySensors Relay example #define RELAY_ON 1 // GPIO value to write to turn on attached relay #define RELAY_OFF 0 // GPIO value to write to turn off attached relay void setup() { pinmode(inputButton,INPUT); pinmode(outputRelay,OUTPUT); // put your setup code here, to run once: } void loop() { // put your main code here, to run repeatedly: if (digitalRead(inputButton) == 0) { digitalWrite(outputRelay,RELAY_ON); wait(2000); // wait 2 seconds digitalWrite(outputRelay,RELAY_OFF); // now wait for door to close while(digitalRead(inputButton) == 0) ; //does nothing until reed switch opens } } There are some subtleties that I may have glossed over, but this is the gist. By looking at the MySensors Relay example, you'll see how to integrate this into a MySensors environment. That's where you'd want to get the RF Nano. I've made the assumption you're familiar with the Arduino IDE and you've looked into the MySensors environment.

Quick Range Check on the WIO-E5-LE. The LE version uses only the low power PA, +14dBm max. Using the default settings except for 915MHz #define MY_SX126x_FREQUENCY (SX126x_915MHZ) #define MY_SX126x_LORA_SF LORA_SF7 #define MY_SX126x_LORA_BW LORA_BW_125 #define MY_SX126x_LORA_CR LORA_CR_4_5 I get about 190 meter range, just walking around the neighborhood, line of site except for some trees and power lines. No tuning on the antenna. Just using a 77.9mm wire. Not as dramatic as some have achieved with LoRa radio's, but plenty good enough for my house and yard : )

@OldSurferDude yeah, 10 virgin nodes powered up at the same time is a bad idea I seem to remember reading somwewhere here warning aginst that. If yu have node ID trust issues with Mysensors you should move your address to different locaion as 0x00 is used by Mysensors... just sayin..;)

@fsgraz Did some testing Today and my RFM range is over 80 meters node to node, with no long range antenna. That will be my next test, just waiting for a shipment from China to arrive. I did how ever notice an extreme improvement when I connected the gateway through a USB hub and then started to dig through the forum. @AWI once wrote about using an external PSU to power the long range NRF PA/LAN. I'll try that this weekend as connecting it to they USB port of my PI extended the range to 20 meters Node to Node.
