Howdy, I’d like to set up a trigger that sends me a notification of the sensor.washingmachinepower going to 0, but only after sensor.washingmachinepower has gone over 500.
So, another way to put it is to trigger at 500, but then wait for 0 before completing the action (in this case, notifying me).
I’m about 2 weeks new to this, so sorry if this is a dumb question.
Thanks
Here are few advices:
Im sure there are better ways but here is how I solved it:
First I created a sensor:
- platform: template
sensors:
washing_maching_is_running:
friendly_name: Washing Machine Is Running
value_template: >-
{% if states('sensor.washing_machine_power_switch_power')|float > 3 %}
true
{% else %}
false
{% endif %}
And the automation to notify:
- id: notify_wash_cycle_completed
alias: Notify Wash Cycle Completed
trigger:
- entity_id: sensor.washing_maching_is_running
platform: state
to: 'false'
for:
minutes: 3
action:
service: script.set_washing_machine_alert
The waiting 3 mins solves the problem of getting false negatives when the power drops between cycles.
Here’s something simple that you can experiment with and enhance.
- alias: example 1
trigger:
- platform: numeric_state
entity_id: sensor.washingmachinepower
above: 500
for: "00:01:00"
action:
- wait_for_trigger:
- platform: state
entity_id: sensor.washingmachinepower
to: 0
for: "00:00:05"
- service: persistent_notification.create
data:
title: "{{ now().timestamp() | timestamp_local() }}"
message: "Washing is done."
It uses a Numeric State Trigger to trigger when power exceeds 500 and remains above 500 for a duration of at least a minute. You can adjust the duration to suit your needs. The point of using for: is to ensure it doesn’t trigger due to a spurious, momentary power spike.
After it triggers, it proceeds to execute action: where it waits for another trigger, a State Trigger, when the power drops to 0 and remains 0 for a duration of 5 seconds (adjust to suit your needs or even eliminate it if you feel it’s not needed).
Finally, it calls the persistent_notification service to post a message in the UI consisting of the current date and time and a brief description (change this to whatever service you prefer).
You can enhance wait_for_trigger with a wait_timeout to protect from waiting forever should, for some unexpected reason, the power never return to 0.
If you’re interested, I’m currently doing something a bit more sophisticated for my washing machine. Based on its power consumption characteristics over an entire washing cycle, I’m inferring what it’s doing.
I gathered data for five wash cycles and discovered that I could not determine the difference between power consumed during washing and rinsing because their respective power ranges overlapped (i.e. the same power consumption is reported for washing and rinsing).
Here’s a sample waveform of the stop/fill/wash/spin/drain phases followed by fill/wait phases (the trough) and then the rinse/spin/drain/stop phases.
The resulting Template Sensor can report:
- stop (no power consumed)
- fill (filling water for either washing or rinsing)
- run (agitation for either washing or rinsing phase)
- pulse (representing the power spike when the spin cycle begins after washing or rinsing)
- wait (short waiting period before the rinse cycle begins)
However it can’t differentiate between run being a wash or a rinse purely on power consumption (or fill or pulse).
The solution is an automation, triggered by changes to the Template Sensor, that steps through the discrete phases of a normal wash cycle:
- 'stop'
- 'wash fill'
- 'wash'
- 'wash spin'
- 'wash drain'
- 'rinse fill'
- 'rinse wait'
- 'rinse'
- 'rinse spin'
- 'rinse drain'
- 'unknown'
The phase are stored in an input_select and the automation steps through them based on the Template Sensor’s previous state and current state. In other words, if the Template Sensor changes from stop to fill, the automation is triggered and sets the input_select to wash fill. When it changes from fill to run, the input_select is set to wash. From run to pulse, sets it to wash spin and so on and so on.
This blog post by Phil Hawthorne inspired me to use an automation and input_select to report the washer’s current operating phase. I simply adapted it to use a Template Sensor because of the inability to distinguish between washing and rinsing phases directly from the current power consumption.
The associated Template Sensor and automation are posted below.
My washing machine is plugged on a TPLink HS110.
I’m using the consumption to detect start of wash cycle and end of it.
I use an input boolean to remember if a cycle is in progress. (called 'lavage") This lets me show the status of washing machine (for instance, if I ran a cycle, went away, my wife comes home and can see it’s in progress. Washer is in the basement)
Beginning of a cycle is consumption going over 30W. Could be more 500W for instance but I found this value enough to avoid any false positive.
End of a cycle is consumption going under 3W for 5mn. Pauses during cycle never drop so low for so long. Anyway, there’s a 1mn delay before you can open it…
You’ll have to check what your machine does. 0 isn’t a good value as there’s always a little bit power used (around 0.5W in standby, up to 5W when delayed start is active, around 2W when on)
2 automation, start and end :

- service: input_boolean.turn_off
entity_id: input_boolean.lavage
- wait_template: "{{ is_state('binary_sensor.somebody_home', 'on') }}"
- service: xiaomi_aqara.play_ringtone
data:
gw_mac: 7811dcb06b6b
ringtone_id: 12
ringtone_vol: 10
- delay: 00:30:00
- service: light.turn_off
data:
entity_id: light.gateway_light_7811dcb06b6b
Note that the “end” automation is a restart one, because it can last long (wait template until someone is home + 30mn) and it happens that another quick cycle is started at the end of the main (example : drying cycle )
This is another simple recipe that has all kinds of use cases.
I use a Tuya CE Smart Plug from Costco flashed with Tasmota/MQTT. After observing several different types of cycles (Normal, Bulky, Rinse etc) using History, I determined all I have to do is wait for the plug to go to trigger a current greater than the quiescent current + some (.75 Amps) and then wait for the current to go less that the quiescent current (.3 Amps) for at least 10 Minutes. The 10 minutes is less than any of the fill, wash, drain, spin actions. This will be different for each Washing Machine model.
I used the Tasmota command “TelePeriod 10” to send the power telemetry every 10 seconds. The magic in this recipe is the mode: restart which causes the automation to restart on each action.

Wouldn’t it be fairly simple to just add a esp behind the plastic and “read” the LEDs in the front panel?
We don’t have these luxury problems, our washing machine beeps so loud that the neighborhood knows it’s done, and it doesn’t stop beeping for like 30 minutes.
Could you share your automation? I’ve been collecting the power consumption profile of my washer and dryer and would like to map the numbers to your code if possible
Thanks
Here’s the Template Sensor that interprets the washer’s power consumption and reports an operating state. If it receives a power value that doesn’t correspond to a known range, it simply reports its previous state. For my washing machine, anything in the range of about 10-100 watts doesn’t correspond to a known operating state and is probably a spurious value. This Template Sensor only reports:
washer_state:
friendly_name: Washer State
value_template: >
{% set s = states('sensor.washer_state') %}
{% set p = states('sensor.washer_power') %}
{% if p == 'unavailable' %} unavailable
{% else %}
{% set p = p | int %}
{% if p == 0 %} stop
{% elif p < 3 %} wait
{% elif 3 <= p <= 9 %}
{{ 'fill' if s in ['stop', 'run'] else s }}
{% elif 100 < p < 520 %} run
{% elif p > 520 %} pulse
{% else %} {{s}}
{% endif %}
{% endif %}
The Template Sensor cannot tell the difference if “run” means the machine is washing or rinsing. The same for “fill”, it can’t tell if the machine is filling water for a wash or a rinse. That’s the automation’s job; it interprets the Template Sensor’s change of states into the machine’s true operating state (it sets an input_select):
- alias: Washer Operation
trigger:
- platform: state
entity_id: sensor.washer_state
action:
- service: input_select.select_option
data:
entity_id: input_select.washer_state
option: >
{% set s = states('input_select.washer_state') %}
{% set fr = trigger.from_state.state %}
{% set to = trigger.to_state.state %}
{% if fr == 'stop' and to == 'fill' %} wash fill
{% elif fr == 'fill' and to == 'run' %} wash
{% elif fr == 'stop' and to == 'run' %} wash
{% elif fr == 'run' and to == 'pulse' and s == 'wash' %} wash spin
{% elif fr == 'pulse' and to == 'run' and s == 'wash spin' %} wash drain
{% elif fr == 'run' and to == 'fill' %} rinse fill
{% elif fr in ['fill', 'run'] and to == 'wait' %} rinse wait
{% elif fr == 'wait' and to == 'run' %} rinse
{% elif fr == 'run' and to == 'pulse' and s == 'rinse' %} rinse spin
{% elif fr == 'pulse' and to == 'run' and s == 'rinse spin' %} rinse drain
{% elif fr in ['run', 'fill', 'wait', 'unknown'] and to == 'stop' %} stop
{% else %} unknown
{% endif %}
Thanks for this.
My washer has a baseline of 5W even when it is doing nothing. I haven’t sat there watching the cycles but should do it to adjust the states if necessary. My power profile is 15, 210, 240, 15, 150, 9, 165 and finally 275 (probably the max extract spin cycle) before going back to 5. MQTT messages are sent every 5 minutes and it may be worth changing it to a faster rate temporarily to establish a baseline.
My adjusted thresholds look like this
Is the thought to use the input selector to send notifications?
Thanks
The input_selector is used to indicate the washer’s current operating phase:
- 'stop'
- 'wash fill'
- 'wash'
- 'wash spin'
- 'wash drain'
- 'rinse fill'
- 'rinse wait'
- 'rinse'
- 'rinse spin'
- 'rinse drain'
- 'unknown'
- 'soak'
When the machine is washing it uses between 320 and 420 watts (depends on whether it was set to hand-wash, regular, or heavy-duty). When it’s spinning/draining it’s between 335 and 525. Similarly, when rinsing it’s between 310 and 380. All of these power ranges overlap so if it’s currently reporting 350 watts, is it washing, spinning, or rinsing? You can’t tell the difference, all you can say is it’s in a “run” phase.
The automation’s job is to interpret the Template Sensor’s changes of state into the actual operating phases and set the input_select accordingly. For example, when the Template Sensor changes from ‘stop’ to ‘fill’ that’s the initial filling of water for the wash phase so the input_select is set to ‘wash fill’. A change from ‘fill’ to ‘run’ means ‘wash’ phase has started. From ‘run’ to ‘pulse’ means ‘wash spin’ and so on and so on.
For notifications, I have an automation that checks when the input_select changes from ‘rinse drain’ to ‘stop’. That’s the last phase of the cleaning process.
I’ve also added detection for a ‘soak’ phase. Sometimes I set the machine to pre-wash, where it does a very short wash and then leaves the clothes soaking in the wash water. It remains in ‘soak’ phase until you set the machine to a normal wash. The problem is sometimes I forget and it soaks for an hour (or much longer). Now I’ve set an announcement to report when the machine is in ‘soak’ for more than 20 minutes.
Thanks for the elaborate explanation.
I might start with reliably reporting when the washer is done and then get into more elaborate analysis. Which means watching the sequence of cycles and matching them to the input selector sequence rather than just the final drop from 275 to 5 watts.
i used this code to get the state.

Thank you for laying this out, just have a couple of questions.
I was able to translate all state option but these.
- Kreukbeveiliging (wrinkle/crease)
- Klaar (clear)
- Uit
Looked them up on the translate platform but not sure how they apply to laundry.
Also how are the states determined to start with.
Thank you
carltonb
i hope i dit the translation oké
options:
- Standby = Standby (power plug turn on but washing machine off)
- Voorwas = Prewash
- Spoelen = Rinse
- Wassen = Washing
- Centrifugeren = Spin
- Kreukbeveiliging = wrinkle protection
- Klaar = Done
- Uit = Off (power plug turn off)
That is perfect, thank you.

Can above and below be in single quotes ?
I would leave a number without it, I guess it’s a string then.
This code generated by Home Assistant GUI. I have added automation from GUI and copied code from automation.yaml file. So syntax is correct.
OK… Are you sure it’s not triggered ? Or that it is but never pass the wait_for_trigger next ?
Do you see it running ? Are there traces ?
What should it do. I understand that :
it should run when power is above 1 (W ?)
then it wait 30s max until consumption drops bellow .3 (W again ?)
But does this actually happen ? Ain’t that too short so it doesn’t ever continue ?
