Having issues where restarts are resetting last_changed time of numerous entities - so I figured I’d try to hack together a python script that I can execute in an automation upon HA startup to reset the last_changed time of a handful of entities.
After various searches and piecing a number of forum threads together, I’ve unfortunately reached at a stand-still. I’m running Hassio in Docker on a NUC. I’m an Ubuntu NOOB, so used this: https://www.juanmtech.com/set-up-hassio-in-docker-and-in-an-ubuntu-server/ to setup Hassio on the NUC.
I’ve created a /config/python_scripts directory and added :python_script to configuration.yaml
I’ve created a real_last_change.py script (code immediately below) and put it in /config/python_scripts/
import sys
import pymysql.cursors
from datetime import timezone
## entity_id = sys.argv[1]
entity_id = data.get('entity_id')
mysql_host = '127.0.0.1'
mysql_user = 'user'
mysql_pass = 'pass'
mysql_db = 'homeassi'
def utc_to_local(utc_dt):
return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)
db = pymysql.connect (host=mysql_host, user=mysql_user, passwd=mysql_pass, db=mysql_db)
cursor = db.cursor(pymysql.cursors.DictCursor)
sql = """SELECT state,last_changed FROM states WHERE entity_id = '%s'
ORDER BY created DESC LIMIT 100""" % (entity_id)
cursor.execute(sql)
result = cursor.fetchall()
db.close()
for idx, row in enumerate(result):
state_act = row['state']
date_act = row['last_changed']
if idx == 0:
state_last = state_act
date_last = date_act
if state_last != state_act:
real_last_changed = date_last
break
else:
state_last = state_act
date_last = date_act
print(utc_to_local(real_last_changed).strftime('%Y-%m-%d %H:%M:%S'))
I’m trying to execute in developer tools -> services as such:
![image]()
The intended result is to scan the DB and update the entity’s (switch.front_drive_gate) last_changed time to the ACTUAL (not reboot) last time changed.
I’m fairly certain the entity_id = data.get('entity_id') code will correctly used the passed data from the service call correctly, but I can’t, after much searching, figure out what credentials to use to access the DB. Without these, I’m unable to fully test the python script, so could be errors in there I haven’t reached yet.
Anyhow, thanks in advance for any time / help spent / given!
