The hacky, not-reccomended, may break in future solution would be this

Adding IKEA Tradfri Devices with ZHA on Home Assistant

Shortcut and On/Off switches

  1. Remove back cover with philips scredriver and instert provided battery
  2. 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
  3. Select "Add device via this device"
  4. Press the pair button 4 times on the back of the shortcut button
  5. Wait
  6. 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 Tradfri On/Off Zigbee Remote to a 3 way momentary rocker

WIP

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

A hacked Qualcomm SDK OpenWRT 150.05 /lib/wifi/hostapd.sh to get 802.11r working. A copy of my /etc/config/wireless as well

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

  2. Work out the python version you want to work with python --version or python3 --version or which python

  3. Once you have chosen the python version cd to the directory you want the env to be stored in

  4. run /path/to/my/python3 -m venv nameOfEnv of course this may just be python not python3
