Thank you @gohan! Retail solution is not the keyword here. What I am searching for is an authorized/lawful (safe) solution.
I decided to do my own node (mysensors) with a cheap relay module for the arduino. Once I achieve the desired functionality I will change to some more robust hardware. Following your suggestion this could be a z wave roller shutter (e.g. fibaro or qubino).
I am trying to do a very simple node with two relays for control of my venetian blinds.
When the node receives an ON signal from the controller a relay is going to turn on for x seconds (line 115 in the below sketch). The mysensors function wait() is used to control the time (line 117). If a new message is received from the controller before wait is finished (e.g. OFF), then wait() should stop and the remaining lines of code (lines 118 to 123) should not be executed. How is that achieved? Hope someone can help. Thanks.

Hi!
I would like to control some 230VAC equipment (for now roller shutters), based on inputs from my mysensors sensors (temperature and light). For controller I use domoticz.
I would like a safe, robust and preferably authorized/lawful solution (I'm in EU/Denmark).
I came across the following solutions:
https://aeotec.com/z-wave-plug-in-switch
https://sonoff.itead.cc/en/products/sonoff/sonoff-basic
https://dlidirect.com/products/iot-power-relay
I think the first one and maybe the second one will be authorized/lawful...? However, I have experience only with mysensors and neither z wave nor sonoff...
Anyone has some experience/thoughts/suggestions to share?
Thanks.
@gohan I recently had some problems with fota and the sensebender sketch you refer to. In this thread @tekka suggested me to enable smart sleep. I used
smartSleep(MEASURE_INTERVAL);
It seems that the smartSleep function has a "built in" MY_SMART_SLEEP_WAIT_DURATION_MS (which defaults to 500 ms). This makes the OTA_WAIT_PERIOD in the sensebender sketch redundant. I deleted it from the sketch.
FOTA now works successfully with my sensebender boards.
@tekka Thank you. However, it turned out that your advice was only part of the solution.
In order to solve the problem I had to also change the sensebender from 2.1.1 to development branch.
My rpi gateway uses development branch (due to reasons discussed here). Does the version mismatch between node and gateway explain why FOTA was not working?
I use the "official" sketch for the Sensebender Micro. However, with "MEASURE_INTERVAL = 6000" and "FORCE_TRANSMIT_INTERVAL = 1" in order to transmit every 6 seconds.
Gateway is rpi ethernet.
MYSController 1.0.0beta (build 3316), "Sensebender board = TRUE", "Battery-powered / sleeping = TRUE" gives the following message but nothing more happens.
If I replace sleep by wait in the sketch and set "Battery-powered / sleeping = FALSE" in MYSController then FOTA works flawlessly. But then node is not sleeping.
Anyone knows how to get it working with a sleeping node?
Using FOTA in myscontroller works only occasionally for me. Sometimes it works fine. But most often I get the following messages and nothing more happens.
The node is a sensebender micro. Gateway is rpi ethernet.
Has anyone experienced something similar? Anyone knows how to solve the problem?
EDIT: Problem solved. Reading this post I now understand that in order to get new fw into the node one has to update the sketch, refresh the repo in MysController and assign it the node.
@NeverDie Thank you!
To me it seems as if it is not an option to order an antenna from CDEbyte through aliexpress.
Can I use any 2.4 GHz SMA antenna? Anything to be particularly aware of? Any suggestions?
@Nca78 I am about to order a few of the suggested modules (PA/LNA module from CDEbyte) from aliexpress. My first deal ever on aliexpress. What about antenna? Will I have to order it separately?
A little hint in the tutorial would have saved me a lot of time too.
@Boots33 Thank you!
Those posts provide lots of useful information.
@gohan Thank you!
The node is a sensebender micro. I would like to use the built-in LED.
I never made a node with the 3 status LEDs. It might be worthwhile for me to look more into that.
I would like to turn on a LED if a node cannot find the gateway (e.g. if the distance is too large) when the node is powered up. How can that be done?
I understand that the send command returns a Boolean that tells whether a message reached the gateway. However, if the node cannot find the gateway on power up the sketch never proceeds beyond #include <MySensors.h>. Is it possible to derive some status from this command?
Do not know if it is of any help, but mine says: gcc version 4.9.2 (Raspbian 4.9.2-10)
@ricorico94 Yesterday I managed to make a working rpi gateway. I am on rpi3, use a socket adapter board for the radio and use domoticz. I posted all the details here: https://forum.mysensors.org/topic/7793/nrf24l01-problems-in-2-1-1-and-2-2-0-beta/24
With 2.1.1 I have the exact same problems.
However, everything seems to be fine with 2.2.0 Beta:
git clone https://github.com/mysensors/MySensors.git --branch development
cd MySensors
./configure --my-transport=nrf24 --my-gateway=ethernet --my-port=5003 --my-rf24-pa-level=RF24_PA_MAX
make
In domoticz:
The result:
pi@raspberrypi:~/MySensors $ sudo ./bin/mysgw -d
mysgw: Starting gateway...

mysgw: TSF:MSG:READ,2-2-0,s=2,c=1,t=1,pt=2,l=2,sg=0:58
After success with 2.2.0 Beta I tried to go back to 2.1.1. However, it still does not work.
I am on rpi3 and use a socket adapter board for the radio.
@skywatch Thank you! That solved my problem.
I followed the instructions carefully. However I get an error. Can someone help?
git clone https://github.com/mysensors/MySensors.git --branch master
cd MySensors
./configure --my-transport=nrf24 --my-gateway=ethernet
This results in a warning:
