Aqara Smart Wall Switch H1 (with Neutral, Single Rocker)

I wanted to see if I could tap of 5v from an aqara zigbee rocker to power a neabry Amazon Fire HD8 smart home display.

The device

The teardown

The device is in two parts:

Shortcut and On/Off switches

Remove back cover with philips scredriver and instert provided battery
In home assistant select a ZHA always-on zigbee device - such as a powered light or signal repeater in the same room the shortcut button will end up in
Select "Add device via this device"
Press the pair button 4 times on the back of the shortcut button
Wait
If using an On/Off switch and you want to bind it to a bulb for non-controller dependant control (i.e will work if home assistant is down)

How to wire a 3 position momentary switch to a Tradfri on off switch

The problem

My better half is keen on having Chrome light switches in our house. Unfortunately I am keen to control our smart lighting with Tradfri switches. My original plan was to buy blanking plates and then simply stick the Tradfri On/Off remotes to them. Unfortunately the white plastic on the wife's chrome blanking plates look terrible.

The Idea

How to get 802.11r (Fast Transition) working on Qualcomms fork of OpenWRT 15.05. In this case on a Gl-inet router

Unfortunately just setting the 4 lines as detailed in this reddit post almost works, however hostapd fails to start due to the auto generated r0kh strings having incorrect formatting. The sypmtom was that the network would appear as open and devices would fail to connect.

As far as I can tell at the time of writing, this r0khs are unecessary with WPA2-PSK forms of authentication if ft_psk_generate_local=1 is enabled in hostapd. So I commented out lines 688 - 690 of /lib/wifi/hostapd.sh

How to create a new env for a jupyter workspce

Ensure that the requirement for working with envs are installed sudo apt install python3-venv
Work out the python version you want to work with python --version or python3 --version or which python
Once you have chosen the python version cd to the directory you want the env to be stored in
run /path/to/my/python3 -m venv nameOfEnv of course this may just be python not python3

in my case /usr/bin/python3

Install the packages for compiling $ sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev wget

Set the python version you want $ version=3.8.5

Download $ wget https://www.python.org/ftp/python/$version/Python-$version.tgz ~/
