home-assistant-on-openwrt's Introduction

Script to install Home Assistant on OpenWRT

Home Assistant is an open source home automation platform. It is able to track and control thousands of smart devices and offer a platform for automating control. Details on https://github.com/home-assistant/home-assistant.
Home Assistant supports only Windows, Linux, Mac and Raspberry offically. While this project is to install the Home Assistant on OpenWRT OS. So that you can run a Home Assistant on a router without having to run a 24-hours PC or Raspberry.

Note that OpenWRT is not an officially supported platform by Home Assistant and so not all integrations (e.g. Zigbee binaries) will work in this system.

Hardware Requirements

A complete installation of Home Assistant will take nearly 350 MB Flash and 130 MB RAM. More components require more storage.
Recommend device is GL-S1300. It has a 8 GB emmc, 512 MB RAM and a Quad-core CPU. It is enough for running Home Assistant and its routing function is also completely unaffected.

Software Requirements

Firmware version 3.023 for GL-S1300 or above.

Install using our scripts

We recommend strongly that using our gl-homeassistant.ipk to install the Home Assistant. It provides an one-click installation script and has add Home Assistant into the system boot program.

You can install "gl-homeassistant" easily through the web. Just search "gl-homeassistant" in the "plug-ins" and click "install". Or you can manually install it in the SSH terminal typing this:

opkg update
opkg install gl-homeassistant

After finished installing gl-homeassistant. You can using command in the SSH terminal to start the installation of Home Assistant.

hass-install

Wait for the installation finished. Usually it takes 20~30 minutes.

Install Manually

If you didn't install gl-homeassistant. There is no command named "hass-install". You have to clone this project and excute it manually.

Clone this project

Open the OpenWRT interface through SSH. Using putty or xshell or some other tools.
And then get into the root path and clone this project.

cd /root/
git clone https://github.com/gl-inet/home-assistant-on-openwrt.git

Note that maybe you'd install the git, use command like this:

opkg install git git-http

Start installation

Get into the project folder and start the installation. Make sure your device has connected to the Internet.

cd home-assistant-on-openwrt
./install.sh

It will take 20~30 minutes. After finished, it will print "HomeAssistant installation finished. Use command "hass -c /data/.homeassistant" to start the HA."

Start Home Assistant for The First Time

After installation finished, use command hass -c /data/.homeassistant to start.

Note that firstly start will download and install some Python modules. Make sure the network is connected while first starting. It will take about 20 minutes. If it stuck or print some error messages, don't worry, interupt it and retry hass -c /data/.homeassistant usually works.

It has fully started when print messages like:

Starting Home Assistant
Timer:starting

Enjoy Home Assistant on The Router

Connect to the S1300 through LAN ports or Wifi using your PC or phone. Visit the address 192.168.8.1:8123 , that's the web page for Home Assistant.

Now you can link your smart devices together with Home Assistant.

Missing cURL as dependency

Download and install pip...... try 5. ./install.sh: line 98: curl: not found ERROR! Install pip failed, exit.

Installed cURL and now it's fine.

External Zigbee

Installed on GL-1300 but is not recognising Zigbee usb. Has anyone managed to use an external Zigbee USB?

General HASS error: can't find make

This is so specific, I'm unsure where to submit it. HASS is erroring out installing several python packages due to make not being found. Especially, the zwave modules, but below shows the PyNaCl module.

How do I get make properly installed on the GL-S1300? Or do I need to build these on a different system and bring them into the GL-S1300? I'm trying to get a full HASS system up with a HUSBZB-1.

please help with libopenssl and cryptography=3.2

Hi guys,

Environment:

Platform: OpenWRT running LEDE OpenWrt 19.07.7
homeassistant: 2021.1.5 (latest support Python3.7)
pip3 list
Package Version

cryptography 3.2.1

homeassistant 2021.1.5

opkg files libopenssl
Package libopenssl1.1 (1.1.1j-1) is installed on root and has the following files:
/usr/lib/libcrypto.so.1.1
/usr/lib/libssl.so.1.1

Issue:

I was able to loaded the require packages and started HA on OpenWrt. However, a lot of components (HomeKit, cloud, mobile_app, apple_tv) can't run with the following error

ImportError: Error relocating /usr/lib/python3.7/site-packages/cryptography/hazmat/bindings/_openssl.abi3.so: SSL_library_init: symbol not found

I did my research and found it seems SSL_library_init no longer get supported under libssl.1.1. However it seem after install cryptography (2.8,3.0,3.2), this symbol keep being called by cryptography.

There might be a modification needed at ssl.h to ensure it's not call SSL_library_init but OpenSSL_init_SSL instead as in the following ssl.h from other openssl package

if OPENSSL_API_COMPAT < 0x10100000L

define SSL_library_init() OPENSSL_init_ssl(0, NULL)

endif

Could someone please help recompile ssl.h file that is suitable for this implementation? I tried copy this ssl.h from the net but no luck during reinstall cryptography.

Thanks a bunch.

Install python module: PyNaCl

Add Zigbee Support

I want to help contribute to the project and add Zigbee support, But first because I’ve never worked with openwrt. What language is the code in?

gl-inet device

the plugin is not availible on a glinet device atx1800 is there a way to add the repository or source ?

Add a note about OpenWRT not being an officially supported platform

Please add a note to the README that OpenWRT is not an officially supported platform and so not all integrations will work out of the box.
