My current roller roller Shutter switch are two pushed buttons up and down. No stop button. When release the push button up or down, the shutter will stop. WIll it be compatible with this board or will i have to change the buttons ?

This is great, thanks! One suggestion: add a switch mode regulator that can handle 12 or 24 volt DC input. This will allow small sensor devices to hang off a typical bus network having extra pairs for the central power supply.

Thanks for your fast reply. That sounds easy. And you think that the communication between sensor nodes and Gateway are still possible via wired RS485? I tried to find an example on this site for sending Information from Gateway to sensor nodes. (via SendMessage ?) For example I like to Switch on/off an light that is connected to an relay board at my sensor node. Communcation Flow: OpenHab2 --> MQTT --> Gateway --> RS485 --> Sensor Node --> Relay Board Currently I have an working RS485 Connection between my Arduino Uno's with the use from SoftwareSerial library. During my testings I realized, that the message that I triy to send "Hello" will be sent to the other arduino char by char. Is that true? Because I tried to raise up an pin on HIGH with "if(msg == "Hello")..." But it doesn't worked. Will the sendMsg method from the MySensor library handle this out of the box? Regards, Simon

@kimot in theory you might be right, but in practice... it just works. The propability of collisions is extremely low and this is, as far as I know, the only problem you can worry about. After all, it was not my idea to use MySensors with RS485: https://www.mysensors.org/build/rs485

@kimot No, it is an obvious mistake, I am very sorry. Maybe it is becouse the code in master branch is very old, the newest is not yet on github, but the developement branch is quite new. I am going to fix this soon.

I found this old thread and since I have a Vallox machine it's interesting. RS485 is new to me but MySensors isn't. Can I have a node like this described by Heinz parallel with the "mickey mouse"-display? Using the display's connector? Or is it one or the other? I'd feel better having both (manual display&buttons and connection to MySensors=>Domoticz, in my case).
