Home Assistant

New try, June 2017

Pros: + It works

Negs: - Emulating Hue adds “all switches” and other virtual devices to amazon alexa, without me having configured such behaviour. - Emulating Hue does not support percentage for dimmers?

Installing hassbian got a lot easier. To install Z-Wave use the built in cmd hassbian-config

sudo hassbian-config install openzwave

Copy paste

sudo su -s /bin/bash homeassistant
nano /home/homeassistant/.homeassistant/configuration.yaml

I had to setup the broadlink with the offical app, but from there I could learn the codes with HA. I could not configure a static IP for it, which makes it an unreliable network participant.

Amazon Alexa

I am integrating the Alexa over an emulated hue, because this is one of the easier way. (Amazon should really offer something like this themself.)

Also there is an offline voice service called snips

Home Assistant requires a lot of IT knowledge and patience, but it gives you complete power over the devices and automation. If you are a developer you will love it.

You don’t really need much hardware, just a Raspberry Pi, and some sensor for onto the GPIO pins. I did buy the offical Pi NoIR v2 Camera. So I can, for example, take a picture if the motion sensor triggers, and send it over IFTTT to my phone.

I also got some Fibaro Motion sensors to track the temperature and check how often I go to the toilet each night. Just being able to measure things gives new insight. 😁

I did run into a few issues:

  • My Z-Wave USB stick was not supported, make sure yours is. z-wave-controllers
  • My Fibaro push button did not work with current open-zwave version.
  • My Fibaro Motion Sensor did not accept the negative temperature offset.
  • You have to wake up each z-wave sensor once for home assistant to recognize them fully

Getting Z-Wave to work is really hard, especially if the devices were just recently released.

For more there is a tutorial series on youtube. BRUH Automation

  • Split the configuration from the start. Tutorial
  • Disable the LEDs on any Z-Wave device (in the configuration UI), it is so annoying.

Z-Wave configuration UI

sudo systemctl stop home-assistant.service
cd /srv/homeassistant/src/open-zwave-control-panel/
sudo ./ozwcp -p 8888
sudo systemctl start home-assistant.service

Z-Wave USB stick uses /dev/ttyACM0, but don’t check the USB checkbox.

Working with Home Assistant

Change to homeassistant user sudo su -s /bin/bash homeassistant
Change to virtual enviroment source /srv/homeassistant/homeassistant_venv/bin/activate

Update HA: pip3 install --upgrade homeassistant
Check config: hass --script check_config
Restart: sudo systemctl restart home-assistant.service
