Anyone has a handy script/automation/appdaemon to check if the sensor hasn’t updated it’s value for more than let’s say an hour?
I’m using this automation to check if the temperature and humidity of a DHT22 does not change for 2 hours.
# Sonoff16A notify if no state change for 2 hours
- alias: sonoff16a_state_notifier_on
#initial_state: True
trigger:
- platform: time
minutes: '/5'
seconds: 06
condition:
condition: and
conditions:
- condition: state
entity_id: input_boolean.sonoff16a_alarm
state: 'off'
- condition: template
value_template: >
{{ (as_timestamp(now())-as_timestamp(states.sensor.sonoff16a_temp.last_updated)) > 7200 }}
- condition: template
value_template: >
{{ (as_timestamp(now())-as_timestamp(states.sensor.sonoff16a_humi.last_updated)) > 7200 }}
action:
- service: homeassistant.turn_on
entity_id: input_boolean.sonoff16a_alarm
- service: persistent_notification.create
data:
title: "Sonoff16A"
message: "Sensor Timeout"

Thanks! But wonder if any wildcard can be used to check all of the sensors
Hi! Thanks to this community I have this app in AppDaemon:
File sensors_updates.py
import appdaemon.plugins.hass.hassapi as hass
import shelve
from datetime import datetime
#
# App to notify if a sensor/device_tracker is dead for check_interval seconds
# Source: https://community.home-assistant.io/t/app-to-monitor-sensors/22470/8
# Args:
#
#file: db file to save state and lastchanged to persist HA shutdown
#blacklist: list of sensors/device_trackers not to track.
#check_interval: time interval between check in seconds
# Release Notes
#
# Version 1.0:
# Initial Version
class SaveSensorState(hass.Hass):
def initialize(self):
start_time = datetime.now()
self.timeout_length = self.args["check_interval"]
self.device_db = shelve.open(self.args["file"])
self.listen_state(self.state_change, "sensor")
#self.listen_state(self.state_change, "device_tracker")
self.run_every(self.check_if_updated,start_time, self.timeout_length)
self.blacklist = self.args["blacklist"].split(",")
def state_change(self, entity, attribute, old, new, kwargs):
if not entity in self.blacklist:
#self.log("State change in {}: from {} to {}".format(entity, old, new))
now = datetime.now()
data = {'state': new, 'time': now}
self.device_db[entity] = data
#self.log("Sensor {} value changed to {} at {}".format(entity, new, now))
def check_if_updated(self, kwargs):
#self.log("Checking sensor health")
message = ""
state = self.get_state()
for entity in state:
if not entity in self.blacklist:
type, id = entity.split(".")
#if type == "sensor" or type == "device_tracker":
if type == "sensor":
if entity in self.device_db:
oldState = self.device_db[entity]['state']
oldTime = self.device_db[entity]['time']
#self.log("Old state for {} was {} and old time was {}".format(entity, oldState, oldTime))
if (self.device_db[entity]['state'] == state[entity]["state"]):
now = datetime.now()
elapsedTime = now - oldTime
if elapsedTime.seconds > self.timeout_length:
if message =="":
message = entity
else:
message = message + ', ' + entity
#self.log("Sensor {} is in {} state for 24 hours.".format(entity, oldState))
else:
now = datetime.now()
data = {'state': state[entity]["state"], 'time': now}
self.device_db[entity] = data
else:
self.log("Adding {}, setting value to current state ({})".format(entity, state[entity]["state"]))
now = datetime.now()
data = {'state': state[entity]["state"], 'time': now}
self.device_db[entity] = data
if message != "":
self.log("Sensor {} has not changed for too much time. Consider reseting.".format(message))
#self.notify("Sensors {} have not changed for 24 hours".format(message), name = "as_email", title = "Message from AppDaemon")
tgmmessage = "{} has not changed for too much time. Consider reseting.".format(message)
self.call_service("notify/telegram_dad",message = tgmmessage)
and the entry in apps.yaml
sensors_control:
module: sensors_updates
class: SaveSensorState
file: /home/tim/.homeassistant
check_interval: 21600
blacklist: sensor.dark_sky_summary,sensor.dark_sky_icon,sensor.dark_sky_precip_probability
Good luck!

Thanks that’s what i was looking for. Can you point me to the thread? Seems the code is for appdaemon 3 and i’m still on 2.4 (not ready to take the leap) so maybe be a 2.4 version is posted on the thread?
Anyway, How to adopt this to discord notification?
I have tried as the following but get an error
if message != "":
self.log("Sensor {} has not changed for too much time. Consider reseting.".format(message))
#self.notify("Sensors {} have not changed for 24 hours".format(message), name = "as_email", title = "Message from AppDaemon")
tgmmessage = "{} has not changed for too much time. Consider reseting.".format(message)
self.call_service("notify.ha_discord",message = tgmmessage,target = "my chat id")
The error is like
2018-05-20 18:40:20.487898 WARNING Unexpected error in worker for App sensors_control:

I would use the Services tab in the Developer’s tool to find out potential errors. For instance, I would try the equivalent to this telegram notification (sorry, I don’t run the discord component):
Hope this helps to narrow the issue.
