If this dir does not exist, Python install/compilation must have failed in the first place. As a common failure reason I recognised that it requires quite much space in /tmp. 1 GB worked reliable, which is default on DietPi with 50% of 2 GB RAM+swap.
However e.g. on my testing VMs I have disabled swapfile and 1 GB RAM enabled by default, which then leads to 512 MB /tmp and in ~50% of the cases this made Python build fail with "no space left on device".

Would be good to add this as a check, so if /tmp is below 1 GB, ask to change this on-the-fly and if RAM+swap is below 2 GB then, ask to increase swapfile so that 2 GB is reached.

And we should also error handle all pyenv and pip3 commands, to prompt with failure if anything fails instead of going on and running into harder to debug follow-up issues.

Hello Experts, I am using Raspberry pi-2 & not much linux knowledge, please give me the workable simple guidelines how i can run Home Assistant on my Raspberry Pi-2. if there is any big issue in your side & you need time please give me approximate time line when it will be fixed on it. i do not want to use any other operating system as dietpi is working perfectly since more then two years on my setup. i have not use home Assistant before so that thing is also learning curve for me. so i want make solid dietpi foundation for it. please give me simple guideline to install Home Assistant on Raspberry PI-2

I too am having problems with 6.27. I honestly have no idea what I am doing but somehow get things working but this time around it is not working. The rest of the stuff running are fine.
I only went tontry HA due to Dollarama selling Incipio devices for cheap and I have no Apple products. I was hoping to get a friend with an iPhone over to get the devices connected to the wifi and go from there.

Fore getting a status readout of HA shows it is running but what seems odd to me is that the time to create for the webui is 0.0 seconds and that seems fast for a pi b3+ even if it is running of a 60gb 2.5inch HD.

What I am thinking I may have done is trying commands people posted without backing up first and without underatanding them. I know for a fact that I tried commands without going into the python enviroment.
OP have you tried a fresh install? That is my next goto step when I can get a time slot when the household is not going to use the pihole for a bit and I am homw from work+awake.

I just fixed two bugs and ran a test install which works fine now.

Code: Select all

dietpi-update -1 # When you are already on v6.27 to update to current dev code, else: https://github.com/MichaIng/DietPi/blob/dev/BRANCH_SYSTEM.md
dietpi-software reinstall 157
htop # Wait until CPU usage of HA process goes down
systemctl restart home-assistant # Required currently since first start fails to pull some Python module, no idea why...
htop # Wait until CPU usage of HA process goes down
Access to http://<local_IP>:8123 now works fine.

This ended up working for me. I had to run dietpi-software uninstall 157 and then clean up some things and then run through your steps a few times but it ended up working.

Thank you for taking the time and effort to get this working.

I can confirm it works!

What is the best way to update HA, since the update script with this line doesn't work anymore:

su --shell /bin/bash --command "cd /srv/homeassistant; export PATH=\"/home/homeassistant/.pyenv/bin:\$PATH\"; eval \"\$(pyenv init -)\"; eval \"\$(pyenv virtualenv-init -)\"; pip3 install --upgrade --default-timeout=100 homeassistant" homeassistant

it reports:
bash: line 0: cd: /srv/homeassistant: No such file or directory
pyenv: no such command `virtualenv-init'
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple

There is a bug on Home Assistant side currently, see: https://github.com/MichaIng/DietPi/issu ... -550532477

You can test our workaround and some other enhancements:

Code: Select all

dietpi-backup # Please update/create a backup first
G_CONFIG_INJECT 'DEV_GITBRANCH=' 'DEV_GITBRANCH=dev' /DietPi/dietpi.txt
dietpi-update 1
dietpi-software reinstall 157
If everything works well, you might want to leave it but have the next stable DietPi release installed over the development version:

Code: Select all

G_CONFIG_INJECT 'DEV_GITBRANCH=' 'DEV_GITBRANCH=master' /DietPi/dietpi.txt
If something does not work as expected, please report, so I'll assist quickly, or you might want to restore the backup:

Code: Select all

dietpi-backup -1
What can happen if we decided to go back from dev to master dev_gitbranch after successful HA/system python upgrade (and instalation of TasmoAdmin). Will dietpi-update 1 erase the work done under dev session (TasmoAdmin etc.)?

What is the best way to update HA within this new environment?
dietpi-software reinstall 157 or some other command?

using this script is ok? please test&reply

Code: Select all

#!/bin/bash
echo "Stopping Home Assistant..."
systemctl stop home-assistant

echo "Updating Home Assistant"
su --shell /bin/bash --command "cd /home/homeassistant; source /home/homeassistant/pyenv-activate.sh; pip3 install --upgrade --default-timeout=100 homeassistant" homeassistant

echo "Starting Home Assistant..."
systemctl restart home-assistant

echo "Home Assistant is ready!"

Exactly that should do it. I'll add a script like this with release which in case calls sudo to source the env activation and does the update. HA has no web based updater, has it?
