The interface will be one designed for switching mains from a Pi/Arduino, with proper separation of the high and low voltage sections, even though it doesn't need to be, for a few pounds extra it gave me a much more robust switch. The relay fails open, so the boiler turns off if it dies. To be specific about the scope of my own tinkering, my combi boiler has a dedicated timer control interface, which is accessible to end users. It is of the 'zero volts' type, meaning that you are operating a simple switch, closing a circuit that starts and ends at the main control board, which I DO NOT MESS WITH. You can, however, use xkbcomp to remap the buttons on a specific device ( thanks to Stephen Wing for that tip).

I bought a remote shutter (ab shutter 3) which is a remote control (bluetooth based) for the camera which has two buttons: one for android and for iOS (iphone). Hello, do you know a way to avoid the button going to sleep? I would like to put them in my children bags so that the RPi detects them when they enter the house. But as the button is sleeping, cannot work... How does it connect according to hcitool con yet not be registered as an input device (and register any inputs)?As there are many drivers having the same name, we suggest you to try the Driver Tool, otherwise you can try one by on the list of available driver below. With the battery panel slipped off and the cell removed, it's fairly easy to open the case. Fingernails are sufficient - no screws or glue! I prefer to use the BlueZ D-Bus API directly which is documented at: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/device-api.txt

Is there anything more I could/should think about, in terms of potential risks and mitigations? Reply This is the result of my own risk assessment and mitigation thoughts, and doesn't constitute a recipe for anyone seeking to do the same thing - may be worth considering the above, but research the risks yourself. On Android, you'll need to use a "Button Remapper" app. There's https://play.google.com/store/apps/details?id=flar2.homebutton - I haven't tried it but it claims to do what you want. Reply The technician in the building knew he could not run away fast enough to escape the blast, so he stayed and manually killed the gas. Cheap BlueTooth Buttons and Linux – Terence Eden’s Blog Terence Eden’s Blog ⚙ Theme: Cheap BlueTooth Buttons and LinuxI plan 4 vital safety features, even given that I am using a purpose built timer control interface: I think that this problem is equivalent to remapping the 'volume up' button in the built-in camera app to make video recordings instead of taking pictures. Aha! Thanks for that. Using this Python script I can grab the events directly. Only problem is that the keypresses (Vol+ & enter) are still sent through to the underlying system - and I need to find which /dev/input/event I need. Onwards! Reply Open your camera application on your phone just as you always do when you are about to take a picture. Pressing the selfie-button instantly sends the command to my computer! Well... until the button goes to sleep. The device is powered by a CR2032 battery which, despite the power efficiencies of Bluetooth, isn't magical.
