Pimatic don't connect to arduino nano clone

---

Yes so it means that your nano clone should work (mine works).
I assume you already try to reboot and restart pimatic 2 or 3 times?

Check that https://github.com/pimatic/pimatic/issues/222#issuecomment-57917641
maybe it can help

info [pimatic-homeduino]: Connected to homeduino device.

I don’t explain it.
I don’t know why arduino is connected right now. I restart the rpi and pimatic many times without a possible message and after a restart again just now it works.

I’m speechless

At the moment there are few troubles around homeduino https://github.com/pimatic/pimatic/issues/521#

It works great. But i have a short question. Before i change from pilight to homeduino the 433mhz receiver and transmitter directly connected to rpi. So i’m writing a c program to read the receiver and transmit data from 4 custom sensors (arduino nano with a dht22)

i want to transmit the data from the sensors to the homeduino now. Can i use HomeduinoRFGenericSensor for my Problem?

my current sketch on the sensor arduino

#include <RCSwitch.h>
#include "DHT.h"

RCSwitch mySwitch = RCSwitch();

#define DHTPIN 7
#define DHTTYPE DHT22 //DHT11, DHT21, DHT22
DHT dht(DHTPIN, DHTTYPE);

int sensor_id = 32;
float temp_offset = 0;

void setup() {
  pinMode(2, OUTPUT);  // Either way, we'll use pin 7 to drive the data pin of the transmitter.

  Serial.begin(9600);

  // Transmitter is connected to Arduino Pin #10
  mySwitch.enableTransmit(2);
  dht.begin();
}

void loop() {
  float h = dht.readHumidity();     //Luftfeuchte auslesen
  float t = dht.readTemperature();  //Temperatur auslesen
  
  if (isnan(h) || isnan(t)) {
    //Serial.println("Failed to read from DHT sensor!");
    return;
  }

  // 31 1/0   300  50
  // id +/- temp hum
  unsigned long i = sensor_id * 100000;
  if (t > 0.0) i += 10000;
  i += (int)(t+0.5) * 100;
  i += (int)(h+.5);
  //Serial.print("send ");
  Serial.println(i);
  mySwitch.send(i, 24);
  delay(60000);
  //delay(10000);
}

In theory yes, it’s the purpose of the generic sensor
you can get the client (ie sensor side) here : https://github.com/Yves911/generic_433_sender
you will have to adapt that for your specific need.
On the pimatic side you will just have to declare the new device

  ]
},

I am now using this for 2 sensors since 5 months, it works perfect!

https://github.com/Oitzu/generic-rfbox/tree/development/libraries/PimaticProbe
Written a class for this purpose.
Look at the examples how to use it.

it works perfectly last 5 days until i’m updating pimatic and pimatic-homeduino plugin today. If i’m connecting to console i’m see all

ready

but my pimatic show only this and i can’t switch my devices on/off after the last update today.

17:48:46.896 [pimatic-homeduino] info: Connected to homeduino device.
debug [pimatic-homeduino]: data: "ready"

is this a problem of the current version?

having no problems here after the update to homeduino 0.8.40.
all parameters working in normal range
