Why not build ffmpeg?

~/termux-packages $ ./build-package.sh ffmpeg -s
./build-package.sh: line 60: jq: command not found
ERROR: No package ffmpeg found in any of the enabled repositories. Are you trying to set up a custom repository?

You need to install jq:

pkg i jq

Or, here’s a compiled package of ffmpeg 5.1.2-7 for aarch64 that I have just built for Termux

Obviously, this is a binary provided by an internet stranger (me), so scan and use at your own risk

Use dpkg -i ffmpeg_5.1.2-7_aarch64.deb to install.

My aiodiscover/network.py was giving
FileNotFoundError: [Errno 2] No such file or directory: '/etc/resolv.conf'

If you are rooted (and don’t want to use termux-chroot), you can solve this error as follows: (thanks to askubuntu.com/a/175742)

Run
mount -v | grep "^/" | awk '{print "\nPartition identifier: " $1 "\n Mountpoint: " $3}'
and look for the mountpoint / (on my device it’s the first printed). You need the partition identifier for this mountpoint. In my case it was /dev/block/platform/soc/624000.ufshc/by-name/system

Then you can run:

sudo mount -o remount,rw THE_PARTITION_IDENTIFIER /
sudo cp /data/data/com.termux/files/usr/etc/resolv.conf /etc/resolv.conf
sudo mount --bind /data/data/com.termux/files/usr/etc/resolv.conf /etc/resolv.conf

Now resolv.conf exists in the /etc folder.

Thanks, it’s work on HA 2023.5.1!

Susesfully installed 2023.5.4 on Android 7 Huawey tablet using main, jambalaya posts and
pip install git+https://github.com/gilcu2/aiodiscover.git for /etc/resolv.conf problem when no root

Like that ```
aiohttp-3.8.1 step doesn’t needed any more because homeassistant install remove it and install 3.8.4

Has any of you mitgated this?

[homeassistant] Error doing job: Exception in callback BaseSelectorEventLoop._accept_connection(<aiohttp.web_...

In my case, it spits out upto 700 such events per second… Must be somekind of a loop.

It happens when internet connection is changed to other interface - f.e. WiFi to Ethernet in my case (I have a USB hub with ethernet port hooked up).

After disconnecting ethernet and restarting HASS, it worked fine for hours.
The moment I plugged in the Ethernet cable, the loop started.

Android - aiohttp exception loop after dis/connecting network/interface.

### The problem ### I advise you to stop using HASS Core on your Android unti…l fix is made or test out a version/setup without the bug. It also might be Android version dependent, but I doubt it. Otherwise you risk bricking your device, maybe even fire hazard... --- **The moment I lose network connection, this error loop starts and logs at a rate of at least ~700/s.** ```2023-06-25 01:29:04.829 ERROR (MainThread) [homeassistant] Error doing job: Exception in callback BaseSelectorEventLoop._accept_connection(<aiohttp.web_... 0x7f95e1fa30>, <socket.socke....0.8', 40000)>, None, <Server socke...8', 40000)>,)>, 128, None) Traceback (most recent call last): File "/data/data/com.termux/files/usr/lib/python3.10/asyncio/events.py", line 80, in _run self._context.run(self._callback, *self._args) File "/data/data/com.termux/files/usr/lib/python3.10/asyncio/selector_events.py", line 159, in _accept_connection conn, addr = sock.accept() File "/data/data/com.termux/files/usr/lib/python3.10/socket.py", line 293, in accept fd, addr = self._accept() OSError: [Errno 22] Invalid argument ``` **Effects:** **1. Overheating and maybe even fire hazard.** 2. Eventual full battery discharge even with quick charger plugged in. 3. Crashing. 4. Lagging. 5. Waste of storage space. 6. Device bricking due to overheating and memory storage wear. Was mentioned in: https://github.com/home-assistant/core/issues/73993 **How to reproduce:** - Switch/disconnect main network device (WiFi/USB tether/Ethernet) or network (SSID) - Even after reconnecting to network, the loop persists. **Reproducibility:** Seems like it's Android specific. ✅ Android - HASS Core - unsupervised Details: Termux rootless install,on Galaxy S8 various Android versions, currently 11 Same result on Honor 10 - Android 10 ❌ HASS OS - HASS Supervised - VBOX machine (official supervised HASS OS image used) ❌ Linux Ubuntu - HASS Core - unsupervised - Ubuntu container On vbox/docker I disconnected network cable/adapter or switched adapters. In both cases I had the same Core 2023.5.3 version installed and my Android config imported with all the devices truly communicating with HASS. **Conclusions**: **1. We need to cover the case of network interface disconnection.** Eventhough Android is not officially supported, it's worth putting HASS on it. It's great use of an otherwise dust-gathering old/screen-cracked Android device. It actually works great even without root! If any of you has some spare time and maybe experience in aiohttp, please provide a fix. I'll also try and prepare one myself later. **Side note:** Never have I ever touched an Android so hot, I could get burns and also got worried about the weird smell. This bug is the best io/cpu/thermal/charging Android stress test I've come across :D With this bug, you can drain battery incredibely fast and it's impossible to maintain charge using QC chargers. It will just die, start vibrating and crying about "wet usb port" from all this HASS hell 😵‍💫 ### What version of Home Assistant Core has the issue? core-2023.5.3 ### What was the last working version of Home Assistant Core? I'm pretty sure it didn't occur in some of the previous versions, but not sure which one. ### What type of installation are you running? Home Assistant Core ### Integration causing the issue happens on clean hass core ### Link to integration documentation on our website _No response_ ### Diagnostics information _No response_ ### Example YAML snippet _No response_ ### Anything in the logs that might be useful for us? _No response_ ### Additional information _No response_

Has anyone tried the chrootted HASS?
My device is rooted and maybe just switching to the chrooted install will solve most issues?

Hello, thanks for this guide! I’ve managed to apparently succesfully install this on two separate android devices, different phones, on different android versions, but with both, once I actually run home assistant, I seem to be forever stuck in ‘home assistant is starting, please wait…’, even though I left one such device running overnight, seeing if that would magically help. There doesn’t seem to be any errors showing up in termux either, to try and point me in any direction.

Did anyone encounter this too? Any idea what I could try?

Thanks!

you can install htop and navigate with arrows (right and down)
it’s enough to see what HA is trying to install

LJK · February 20, 2024, 11:04am

This is great!

It’s been over a year since you posted this, how’s life been using it over that time?

This widens the available off the shelf hardware enormously and tablets have internal batteries so will cope with power cuts up to a point. Many Zigbee sensors will run on the internal battery for a few hours too. As well as run of the mill tablets, there are loads of low cost wall mounted and table top Android tablets for smart home use out there.

Cool, I also have a plan to get running home assistant on galaxy tab s7 which is mostly at home. Pity that there is not a simple way to do it as even most mid range phones are more powerful than raspberry.

Hi @Ramblingman thank you very much for this complete guide.
I would like to know which version of homeassistant is the one you installed in this guide, since when initializing home assistant I am having several errors and I think it may be due to incompatibilities when using a newer version, so I would like to try with the version that you used. Thank you so much
PS: sorry for the English, use Google Translate
