Android: Disabling Battery full alert

I keep hearing in my dreams a sort of "ding" sound made by my phone (running Android 4.1). It's trying to tell me to disconnect the charger from the wall socket (to be greener), but unfortunately it's doing this in the middle of the night, and it's annoying. There is no risk to damage your phone if you keep it plugged in beyond this point anyway.

Well, there seem to be apps that let you manage the notification sound (like Battery full notification), but they seem overkill for what I want.

Luckly, I found this thread in my searches: http://androidforums.com/samsung-galaxy-s2-international/331058-stopping-fully-charged-sound.html#post2819281

If you have a rooted phone, you can follow the instructions in the thread, or follow these steps in a terminal emulator on your phone:

su
cd /system/media/audio/ui
mount -o remount,rw /system
mv TW_Battery_caution.ogg TW_Battery_caution.ogg.bak
mount -o remount,ro /system
exit
exit
 It renames the notification sound, so that next time your phone wants to wake you up to unplug the charger, it will have no voice :P

Home Assistant + Android TV = fun

Here's a quick setup guide for controlling your Android TV from within Home Assistant. I've used it to control a genuine Android TV (Philips 7304) and an Odroid N2 running Android TV. For this to work you need ADB access. It can usually be enabled from within Developer Settings. The great part is - you don't need root access! The most important things are described in the androidtv component for Home Assistant: https://www.home-assistant.io/integrations/androidtv/ Make sure you go through the adb setup. My configuration is simple (inside configuration.yaml): media_player:   - platform: androidtv     name: TV Bedroom ATV     host: 192.168.1.61     device_class: androidtv Once Home Assistant restarts, your TV might require you to accept the connection (adb authentication). This happens only once (or until you reset your ATV to factory settings). Once running the integration will show you the current ATV state (on or off) and al...

SmokePing + InfluxDB export + docker + slaves + Grafana = fun

I've been working for a while on this project - with the purpose of getting SmokePing measurements from different hosts (slaves) into InfluxDB so that we can better graph them with Grafana. The slaves run multiple Smokeping instances inside Docker so that they have separate networking (measure through different uplinks, independently). This will not be a comprehensive configuration guide, but a quick "how to" to handle setup and basic troubleshooting. It assumes you already know how to set up and operate a regular Smokeping install with or without slaves and that you are fluent in Smokeping configuration syntax, know your way around Docker and aren't a stranger from InfluxDB and Grafana (sorry, there's a lot of information to take in). 1. Getting Smokeping with InfluxDB support - you can get it either from the official page (most changes have been merged) - https://github.com/oetiker/SmokePing (PR discussion here: https://github.com/oetiker/SmokePing/issues/...

Android: Adding scp/sftp support to dropbear and mounting with sshfs

I have recently received an android smartphone, and one of the first things I did with it was to root it :). This allows power-usres to get the most out of their hardware. The next thing on my list was to set up a SSH server and to be able to transfer files between my Linux system and my phone (by the way, I'm running Android 4.1 and it seems USB mass storage support has been removed. MTP/PTP modes have either horrible transfer speed or are poorly supported in Ubuntu). With the above in mind, the plan was to: Enable tethering on the phone Run a SSH server to support issuing remote commands and file transfer (FTP might have been an alternative, but I'm a SSH adept). Browsing the market I found  SSHDroid which does all that it advertised. Problem is - the free version conflicts with my add-blocking apps and requests that they are disabled to run. For me, this is a big nuisance, so I kept looking. I found Dropbear SSH Server 2 , which is completely free, but doesn'...
