But, there are many events that occur with each button push. For example when I push what is probably "KEY_3" I see this: I already had an aftermarket timer switch, more sophisticated than the onboard timer, but still very closed. Nice! Running xinput query-state "AB Shutter 3" allows us to see which keyboard keys are activated when the buttons are pressed. This will convert the Volume Up to XF86Launch1 and Enter to XF86Launch2 - those are multimedia keycodes which shouldn't be assigned to anything by default. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

Regardless, I figure I could ignore the extra "keystrokes" and use the first one in each burst. But, I'd like to understand what's goin on. The script needs to be re-run every time the Bluetooth connection is re-established. Probably best to run it on reconnect as part of the Python code above. It's pretty easy to set keyboard shortcuts in the GUI- but how do we do it on the command line? Well, you can't. There's no way to tell a shell to run a program when a specific key has been pressed. And of course anything that applies to handling keyboards in general will apply to the remote as well. (Assuming it's a HID. But they usually are. Bluetooth headsets with buttons are a completely different story then.) The selfie remote shows up in Android as a Bluetooth keyboard, right? Or as a HID (Human Interface Device) in general.After a few minutes of idleness, the device goes to sleep. Pressing any button wakes it up and repairs the connection - but then another button press is required to send a key press. The pairing process only takes a couple of seconds, so it's not quite instant. Make it do something useful So, that remaps the inputs for that Bluetooth button. Ok, but how do we get XF86Launch1 to launch a program? I have this on now, but have tested previously replacing it with a standalone Pi, implementing a simple timing schedule. What we have here now is an AB Bluetooth remote shutter ( ASHUTB Bluetooth Remote Shutter). And we hope we can provide you as much information you need to know about this another cool gadget with our review. For those who are fond of taking their own photos with their own Android or iOS smartphones – also known as “ selfie”– then you’re going to love this one too. The AB Bluetooth remote shutter is one of the 2 popular wireless remote controllers which enables you to take your own picture, far from your own device. You may not know it yet but I see more and more people getting their own Bluetooth remote shutter and I only know 2 of these kinds so far – IPEGA Bluetooth remote shutter and the other one is this AB Bluetooth remote shutter. In most cases, you will notice people have this in family gatherings, reunions with friends, malls, streets, and some were using it for fun. They seem to enjoy taking their picture in a much farther view rather than extending your arm trying to ensure that all of you fits in that small frame. 🙂 I 100% agree with you, and a great safety warning. Glad that situation did not end as badly as it could have.

If your device is compatible, you might want to follow their recommended pairing steps listed on their owner's manual link. Just in case, the steps are here: Easy to set up, Easy to use The Pi, Arduino and relay are in a sensible electronics enclosure, with good cabling, glands and cable strain relief, for the control wire, 5VDC in and wired ethernet. There is no onboard wifi, and the mains power point is some distance from the Pi.

Goal

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. Caution: The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The off road satnav loaded with OS Maps which I use for navigation on my MTB sits in a waterproof case attached to my stem. The whole setup is great, I don't have to faff about with maps and it lets me spend the maximum amount of time riding as fast as I can. Plus it is much cheaper than a Garmin 800/ 810 and I can get far better real time stats during my ride. This device complies with Part 15 of the FCC Rules.
