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:

I run domoticz and use influxdb to collect sensor data on a rpi 3. After 2 - 3 months I see SD card corruption and have to restore the SD card from a backup image. This approach is starting to become annoying.
Did anyone find a good and stable way to run rpi 24/7 with influxdb (or other database) collecting sensor data?
@tbowmo Do you use the tmpfs for storage of influxdb data also? Did you add an external disk? If so what is your experience with that approach?
@Viciousman Thank you!
How do I create a Ethernet gateway?
Will I have to build this: https://www.mysensors.org/build/ethernet_gateway
or
Will I have to do some kind of configuration on the rpi and continue using my serial gateway?
Is it possible to do FOTA from my raspberry pi (serial gateway + domoticz)?
As it is now I move the gateway from the rpi to a windows pc running MYSController. It would be nice to avoid this step.
Arduino UNO can be perfectly well used. I use Arduino Uno for some of my mysensors. Connect VCC of the radio (NRF24L01+) to 3V3. Other pin numbers are the same.
@breimann
I use remot3.it to provide remote access to domoticz running on a rpi3. It is very simple to set up.
It works great with a web browser on a pc. I did not test it with the domoticz android app yet.
What @Redguy describes is very close to what I wish to accomplish with my HVAC system.
If I start out with modbuspoll and a moxa converter as suggested by @Redguy a few questions arise to me:

@Mark-Swift In the sensebender sketch I replaced
gw.send(msgTemp.set(temperature,1));
with
if(gw.send(msgTemp.set(temperature,1)))
{
digitalWrite(LED_PIN,LOW);
}
else
{
digitalWrite(LED_PIN,HIGH);
}
LED is OFF if meassages are successfully delivered. LED turns ON if meassage delivery fails and stays ON until a new meassage is successfully delivered.
Note that I use mysensors 1.5 as I did not yet update to mysensors 2.0. In 2.0 gw. is not needed
@carmelo42 Any size between 4.7µ any 47µ will be fine.
Thank you all for your comments!
We ended up discarding the acer and bought an asus gaming laptop at a similar price.
So far my son is very satisfied.
Hi,
My son has saved up some money for his first laptop. It will primarily be used for minecraft.
I consider to recommend him to buy one of these two, which are within his budget. However I cannot decide which (if any). Any suggestions?

@loralg I successfully use a nRF24L01+PA+LNA on the gateway and regular nRF24L01+ on the sensors.
There is a lot of information and hints available in the forum regarding the nRF24L01+PA+LNA . See e.g. here:
https://forum.mysensors.org/topic/3719/nrf24l01-vs-nrf24l01-pa-lna/2
In my case, however, the nRF24L01+PA+LNA works fine without any fix or special attention.
A big thanks to all of you! I learned a lot from your answers.
For now I think that hardware ack is sufficient. I can now place a sensor in different locations and tell from its LED wether or not messages are recieved by the gateway (I have no repeater nodes yet).
I did successfully build the Power Meter Pulse Sensor and use it with Domoticz.
Next, I would like to have a LED on the sensor indicate whether messages are successfully delivered (e.g one blink) or not (e.g. three blinks).
As far as I understand the ack should be set true while sending. E.g.
gw.send(kwhMsg.set(kwh, 4)),true)
However, I cannot figure out how to evaluate the result. I.e. if the destination node send ack back.
There is a lot of useful info here:
https://forum.mysensors.org/topic/2147/office-plant-monitoring
Look also at the three links in the first post.
Thanks @AWI! A level converter is exactely what is needed.
On the battery powered sensor build page it is suggested to power 5V sensors using a step up converter. I guess that most 5V sensors use 5V logic levels for their digital output. Furthermore, as far as I understand the ATmega328P digital inputs do not accept voltages higher than Vcc + 0.5V (see datasheet p. 299). Consider as an example a sensebender operating at low battery level, say 2V. Wouldn’t the sensebender be harmed by a 5V digital signal from an attached sensor?
I hope someone in here can help explain how to properly connect a 5V sensor to battery powered device.
The circuit diagram that I posted above did not show communication lines between the K-30 and the sensebender. These are included here:
However, I now realise that the K-30 and the sensebender cannot be connected this way because the sensebender (ATmega328P) digital inputs do not accept voltages higher than Vcc + 0.5V.
Does anyone have a suggestion how this problem can be solved?
@alexsh1 As you can see my experiments with powering the K-30 from batteries are not going that well...
I'm very interested in this too!
I have two Senseair K-30 CO2 sensor modules (http://www.co2meter.com/collections/co2-sensors/products/k-30-co2-sensor-module, http://www.senseair.com/products/oem-modules/k30), which use the non-dispersive infrared (NDIR) principle. The same principle is used in MH-Z14 as far as I understand.
The K-30 consumes quite some current and is not ideal for operation from batteries. However, my thougth is to connect it to batteries using a MOSFET, making it possible to switch on/off the sensor using an arduino output. Something like this:
In order to save battery the strategy is to:
The required warm-up time given in the datasheet is about 1 minute. However, a comparison of two K-30s - one powering up/down and the other powered on constantly - showed that a satisfactory measurement is obtained less than 10 seconds after powering up.
Any thougths on this issue will be very much appreciated.
Hello!
I decided to soon buy a couple of sensebender micros. However, until now I have only experience with arduino uno and nano. I understand a FTDI a progammer is needed to program the sensebender. Is the itead FTDI programmer found here https://www.itead.cc/foca.html a suitable choice?
