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.

* DESCRIPTION
* This sketch provides an example of how to implement a humidity/temperature
* sensor using a DHT11/DHT-22.

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
