Home Assistant Blueprints Updater

this script has been moved to its own github repo and can now be found on https://github.com/koter84/HomeAssistant_Blueprints_Update/

blueprints_update.sh

#!/bin/bash

self_file="$0"
self_source_url="https://raw.githubusercontent.com/koter84/HomeAssistant_Blueprints_Update/main/blueprints_update.sh"

# print info function
function _blueprint_update_info
{
	echo "$@"
}

# create a temp file for downloading
_tempfile=$(mktemp -t blueprints_update.XXXXXX)

# start message
_blueprint_update_info "> ${self_file}"

# update
wget -q -O "${_tempfile}" "${self_source_url}"
wget_result=$?
if [ "${wget_result}" != "0" ]
then
	_blueprint_update_info "! something went wrong while downloading, exiting..."
	_blueprint_update_info
	exit
fi
self_diff=$(diff "${self_file}" "${_tempfile}")
if [ "${self_diff}" == "" ]
then
	_blueprint_update_info "-> self up-2-date"
else
	cp "${_tempfile}" "${self_file}"
	chmod +x "${self_file}"
	_blueprint_update_info "-! self updated!"
	exit

_blueprint_update_info

I'd like to be able to update also from shell, so could you please change the cd line in something like:

cd /config/blueprints || cd $(dirname "$0")/../config/blueprints || exit 1

There are various bugs in the handling of blueprints with no source_url set:

• custom- uri's are not preserved:
  • ideally if the updated script has no source_url set it should be re-added (without custom- prefix, that breaks HA).
• The value is added to the file using a wrong syntax (leading to HA not to load it, breaking automations)
  • It should not use source_url:, but source_url: ''.

This is the error when the invalid source_url value is found:

2022-11-23 02:40:10.661 ERROR (MainThread) [homeassistant.config] Invalid config for [automation]: Invalid blueprint: invalid url for dictionary value @ data['blueprint']['source_url']. Got None (See ?, line ?).

The above exception was the direct cause of the following exception:

So the value should be set to the files which have no 

Thanks for this @koter84 .I did some initial troubleshooting with you on this and it looks great here.

I've noticed that blueprint filenames that have spaces or non alpha characters get confused and comes back with non-matching filename. I think this worked at one time, it is not now from this gist version anyway.

Another thing that seemed confused was if I add custom- to a source url, it finds it, updates it, but the url is not in the file when it comes back. Instead we get - source_url: and a blank which fails syntax in HA. I'm pretty sure that was fine early on as well.

I'm thinking perhaps an in-between version is posted here.

Also if there is a way the shell can return a flag if there are updates needed or not would be great. I'm not really wanting to have it just update when I'm not there when it tuns in a timer. I would prefer it runs on the timer, returns some data that we can grab in HA to do a persistent_notification that updates need to be checked. (Webhook with some json message(s), perhaps?)

An enhancement request would be another switch that takes a filename so a single file could be checked or updated as opposed to all.

i have made a full github repository for this script, which you can find on https://github.com/koter84/HomeAssistant_Blueprints_Update/

i'm currently fixing some errors and adding a couple of features, once i commit that to the new repository i'll update this script to auto-update to that repository.
