@hexenmeister on top of explaining where can I get the nrf radio library file for eagle ?

I am building my own controller running on raspi with mysql as database so planning to integrate charts and graphs can give user a interactive view of the sensor data.

Thanks a lot for all the Information

I had this concerned from beginning. I will sound like a noon, but I am working on building a custom controller with loads of user configurable interface. For sake of my understanding is there any diagram or video or any resource regarding how to interface the ATSHA204A with arduino @Anticimex .
If there is something like that it will be of a great help. I am going to post a video soon of my work in progress app which controls the devices. I am also working on a scenario where someone can use the normal switches(existing ones) to operate the device and app will update accordingly. Still making way through the ACK part and the hops as I am using Ruby to do all the work

I am also trying something similar and I get fail in the serial monitor for all the relays I have connected. But after that everything works fine.

I don't want to take out the panels which are holding the switches, max I can do is replace the switch with a Two Way switch, I planned on using ACS712 to sense the current and process the data accordingly in arduino to send a message to my controller but adding a current sensor to each and every switch seems to be a cumbersome process, Is there anything better then the way I am thinking.

Note: Removing the current switches completely is out of question at least for me case

@jendrush said:

@mainali I've changed my two way switch to one way. So i can control my light with phisical button, and also by app.

Can you explain further what do you mean actually.

@ferpando I am talking about the normal switches that we have in most of our home switch

I am trying to control the switches in my house I am building my own controller to have all the flexibility that I desire. I am able to control the devices attached to the switches.

The problem is I want the control to be parallel, from app as well as the normal switch which are already present. I have replaced the switch with Two Way switch to achieve this, but I am not able to figure out the state of the physical switch. Is there a way I can know if someone activated a device from physical switch so that I can update the status of that device in my app. Someone can either switch ON/OFF the device using physical switch and corresponding state has to reflect on the app.

what are the ways in which I can achieve this feature

@Xander Thank you for making this clear.
