if you dont want to install anything to restart domoticz when it's crash. you can put crontab to check it with bash script like this

put this on your cront :

*/1 * * * * sudo /opt/Domoticz/scripts/online_check.sh 2>&1 >> /dev/null

and this is online_check.sh

#!/bin/bash
#Title check_domoticz_online.sh
# check domoticz
sudo service domoticz.sh status
# if not found - equals to 1, start it
if [ $? -eq 1 ]
then
sudo service domoticz.sh restart
else
echo "Domoticz running - do nothing"
fi

I see, I never check ethernet script for domoticz, maybe there's a bugs there. I'll check it anyway. but if you try serial gateway, it will run

@kunall which sketch did you use for relay with button? did you modify the sketch?

@kunall which light do you want to turn on/off? mysensors based? or zwave or anothers?
and anyway On Action/Off action it's only an additional query, for example when you turn on/off the light you want to open some url or script then you have to put your url/script there. but it's better for you to use LUA script for automation.

unfortunatelly I use mac, I'll try to install on my virtualbox. thanks for your suggestion

@kunall This might be useful for you:

http://www.mathertel.de/Arduino/OneButtonLibrary.aspx

any suggestion of using others IDE than Arduino Default IDE?

you should use eeprom to store button value, I think you can't use bounce for something like that as far I know. and better for you to use at least 2 button, one for control and another to reset value

@AWI I'am :apple: user, but only Mac. I use android phone :p

Is there any Indonesian here, living in indonesia or abroad?

@clgary solution from @hek, try development branch :p

Tested with development branch and compiled, anyway is there any changes in API between master and development? do I need to reupload skeech to my older running devices if I want to use development branch?

@ntruchsess how do I update my dummy switch value? my german language is not so good to understand everything on fhem. I've created fhem.cfg for my 4 buttons. and create 4 dummy switch for that. but when I press the real button, dummy switch doesn't change the state. but when I press dummy switch on web. the button status is changed.

below is my fhem.cfg

Dummy device status doesnt change when I press the button, how to set the dummy state on reading change? I don't know so much about fhem config file

you have to make an array also for debouncer

Great Post Tim :+1:

I would like to print that one for my pet ;)

I think node ID is given by controller on serial gateway.

is there any sample code for controlling RGB led here?

can you post the source? so everyone can contribute to make something more
