ok, Thanks at all!
You helped me find the mistake!
it was actually because the node could not receive commands because there was a "sleep()" hidden somewhere in each sketch. after I searched all sketches thoroughly and replaced them with "wait()", everything runs without problems:/** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0: Henrik EKblad * Version 1.1 - 2016-07-20: Converted to MySensors v2.0 and added various improvements - Torben Woltjen (mozzbozz) * * DESCRIPTION * This sketch provides an example of how to implement a humidity/temperature * sensor using a DHT11/DHT-22. * * For more information, please visit: * http://www.mysensors.org/build/humidity * */ // Enable debug prints #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_NRF24 //#define MY_RADIO_RFM69 //#define MY_RS485 #include <SPI.h> #include <MySensors.h> #include <DHT.h> // Set this to the pin you connected the DHT's data pin to #define DHT_DATA_PIN 3 // Set this offset if the sensor has a permanent small offset to the real temperatures #define SENSOR_TEMP_OFFSET 0 // Sleep time between sensor updates (in milliseconds) // Must be >1000ms for DHT22 and >2000ms for DHT11 static const uint64_t UPDATE_INTERVAL = 60000; // Force sending an update of the temperature after n sensor reads, so a controller showing the // timestamp of the last update doesn't show something like 3 hours in the unlikely case, that // the value didn't change since; // i.e. the sensor would force sending an update every UPDATE_INTERVAL*FORCE_UPDATE_N_READS [ms] static const uint8_t FORCE_UPDATE_N_READS = 10; #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 float lastTemp; float lastHum; uint8_t nNoUpdatesTemp; uint8_t nNoUpdatesHum; bool metric = true; MyMessage msgHum(CHILD_ID_HUM, V_HUM); MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP); DHT dht; void presentation() { // Send the sketch version information to the gateway sendSketchInfo("TemperatureAndHumidity", "1.1"); // Register all sensors to gw (they will be created as child devices) present(CHILD_ID_HUM, S_HUM); present(CHILD_ID_TEMP, S_TEMP); metric = getControllerConfig().isMetric; } void setup() { dht.setup(DHT_DATA_PIN); // set data pin of DHT sensor if (UPDATE_INTERVAL <= dht.getMinimumSamplingPeriod()) { Serial.println("Warning: UPDATE_INTERVAL is smaller than supported by the sensor!"); } // Sleep for the time of the minimum sampling period to give the sensor time to power up // (otherwise, timeout errors might occure for the first reading) wait(dht.getMinimumSamplingPeriod()); } void loop() { // Force reading sensor, so it works also after sleep() dht.readSensor(true); // Get temperature from DHT library float temperature = dht.getTemperature(); if (isnan(temperature)) { Serial.println("Failed reading temperature from DHT!"); } else if (temperature != lastTemp || nNoUpdatesTemp == FORCE_UPDATE_N_READS) { // Only send temperature if it changed since the last measurement or if we didn't send an update for n times lastTemp = temperature; if (!metric) { temperature = dht.toFahrenheit(temperature); } // Reset no updates counter nNoUpdatesTemp = 0; temperature += SENSOR_TEMP_OFFSET; send(msgTemp.set(temperature, 1)); #ifdef MY_DEBUG Serial.print("T: "); Serial.println(temperature); #endif } else { // Increase no update counter if the temperature stayed the same nNoUpdatesTemp++; } // Get humidity from DHT library float humidity = dht.getHumidity(); if (isnan(humidity)) { Serial.println("Failed reading humidity from DHT"); } else if (humidity != lastHum || nNoUpdatesHum == FORCE_UPDATE_N_READS) { // Only send humidity if it changed since the last measurement or if we didn't send an update for n times lastHum = humidity; // Reset no updates counter nNoUpdatesHum = 0; send(msgHum.set(humidity, 1)); #ifdef MY_DEBUG Serial.print("H: "); Serial.println(humidity); #endif } else { // Increase no update counter if the humidity stayed the same nNoUpdatesHum++; } // Sleep for a while to save energy //sleep(UPDATE_INTERVAL); wait(UPDATE_INTERVAL); } void receive(){ }However, I would suggest that the functions "wait()" and "smartsleep()" be mentioned in relation to the MySBootloader in a separate point under "https://www.mysensors.org/about/fota". Maybe under a chapter:
- Enabling FOTA in your sketch
1.1 DualOptiboot only
--> text as before
1.2 MySBootloader
--> ... use smartsleep() and wait() instead of sleep()...

if sensebender gateway is connected via usb, only one instance may access the gateway at a time, therefore "OpenHab" must be terminated first

do not use "sleep()" in the sketches. only "smartsleep()" or "wait()".
use the current dev-branch from "https://github.com/mysensors/MySensorsBootloaderRF24
@rafael156 oh crap ... I put in that lowFuse as FF .. ( I read you had it for 8 MHz INTERNAL .. but nooo you wrote external ... ooops ... is there any way to force write it back without connecting an 8 MHz oscillator to the chip .. I only got 16 MHz oscillators .. or am I screwed for that chip until I go and get one?
