Calibration
-----------
What you need:
- Your ESPHome power measurement plug
- A calibrated power meter that can measure voltage, current, power and power factor
- A large resistive load like an electric heater or kettle, ideally over 1000W
Steps:
- Find the currently used calibration values for ``current_resistor`` and ``voltage_divider`` in your device's YAML configuration or upload a new firmware with some known calibration values to the ESP.
- Plug the ESP power measurement plug into the calibrated power meter.
- Plug the load into the ESP plug.
- Turn on the load and make sure the power factor (PF) displayed on the power meter is 1.0. If it's not, you need to pick a different load.
- Wait for the readings to settle on both the power meter and the ESP.
- Write down the voltage reading of the power meter and the ESP at the same time.
- Write down the power reading of the power meter and the ESP at the same time.
- Write down the current reading of the power meter and the ESP at the same time.
- Use the calculator below to calculate the new calibration values for the ESP. These values will help it accurately measure power, voltage and current in the future.
- Upload the new values to the ESP.

If you run the PM1006 (2.5µm) or PM1006K (1, 2.5, 10µm) independent from the original MCU you need to send a serial command in the first 5 seconds after power is applied to the sensor.

:image: pulse.svg
The pulse meter sensor allows you to count the number and frequency of pulses on any pin. It is intended to be a drop-in replacement
for :doc:`integration sensor </components/sensor/pulse_counter>`, but offering better resolution.
It measures the time between rising edges on a pin, for each pulse it outputs the frequency in pulses/min.
for the :doc:`pulse counter integration </components/sensor/pulse_counter>`.
Rather than counting pulses over a fixed time interval, the pulse meter sensor measures the time between pulses. The precise manner in which this is done depends on the ``internal_filter_mode`` option. This leads to a higher resolution, especially for low pulse rates, as the pulse counter sensor is limited by the number of pulses within a time interval.
Here's a comparison of the two sensors; both are set to an update interval of 10 seconds (using the ``update_interval`` and the ``throttle_average`` option respectively):

- **name** (**Required**, string): The name of the sensor.

time is detected, it’s discarded and no pulse is counted. Defaults to ``13us``. For S0 pulse meters that are used to meter power consumption 50-100 ms is a reasonable value.
- **internal_filter** (*Optional*, :ref:`config-time`): If a pulse shorter than this time is detected, it is discarded. Defaults to ``13us``.

One of ``EDGE`` and ``PULSE``. Defaults to ``EDGE``. In ``EDGE`` mode subsequent rising edges are compared and if they fall into an interval lesser than the internal filter value, the last one is discarded. In ``PULSE`` mode the rising edge is discarded if any further interrupts are detected before the internal_filter time has passed. In other words, a high pulse must be at least internal_filter long to be counted. This is useful if you are detecting long pulses that may bounces before and/or after the main pulse.

In other words, a high pulse must be at least ``internal_filter`` long to be counted. This is useful if you have a noisy input signal that may have bounces before and/or after the main pulse.
- **timeout** (*Optional*, :ref:`config-time`): If we don't see a pulse for this length of time, we assume 0 pulses/sec. Defaults to ``5 min``.
- **timeout** (*Optional*, :ref:`config-time`): If we don't see a pulse for this length of time, we assume *0 pulses/s*. Defaults to ``5 min``.

Converting units
----------------
The sensor defaults to units of “pulses/min”. You can change this by using :ref:`sensor-filters`.
For example, if you’re using the pulse meter with a photodiode to
count the light pulses on a power meter that outputs 1000 pulses per kWh,
you can use the following to output instantaneous usage in kW:

:description: Instructions for hacking your power meter at home to measure your power usage.

So an essential part of making your home smart is knowing how much power it uses over
the day. Tracking this can be difficult, often you need to install a completely new
power meter which can often cost a bunch of money. However, quite a few power meters
have a red LED on the front that blinks every time that one Wh has been used.

Tracking this can be difficult, often you need to install a completely new power meter which can often cost a bunch of money. However, quite a few power meters have a red LED on the front that blinks every time that one Wh has been used.
The simple idea therefore is: Why don't we just abuse that functionality to make the power-meter
IoT enabled? We just have to hook up a simple photoresistor in front of that aforementioned
LED and track the amount of pulses we receive. Then using ESPHome we can instantly have
the power meter show up in Home Assistant 🎉

Hooking it all up is quite easy: Just buy a suitable photoresistor (make sure the wave length
approximately matches the one from your power meter). Then connect it using a simple variable
resistor divider (see `this article <https://blog.udemy.com/arduino-ldr/>`__ for inspiration).

- multiply: 6 # (60s / impulse constant) * (1000W / 1kW)
Adjust ``GPIO12`` to match your set up of course. The output from the pulse counter sensor is in
``pulses/min`` and we also know that 1000 pulses from the LED should equal 1kWh of power usage.
Thus, rearranging the expression yields a proportional factor of ``0.06`` from ``pulses/min`` to
``kW``.
And if a technician shows up and he looks confused about what the heck you have done to your
power meter, tell them about ESPHome 😉
Adjust ``GPIO12`` to match your set up of course. The output from the pulse counter sensor is in pulses/min and we also know that 10000 pulses from the LED should equal 1kWh of power usage. Thus, rearranging the expression yields a proportional factor of 6 from pulses/min to *W*.
.. note::
Photoresistors often have a bit of noise during their switching phases. So in certain situations,
a single power meter tick can result in many pulses being counted. This effect is especially big on
ESP8266s. If you're experiencing this, try enabling the ``internal_filter:`` filter option:
The ``pulse_meter`` sensor sends an update every time a pulse is detected. This can quickly lead to sub-second updates which can be a bit much for Home Assistant to handle. To avoid this, you can use the ``average_throttle`` filter to only send updates up to a desired interval:
.. code-block:: yaml
sensor:
- platform: pulse_counter
- platform: pulse_meter
# ...
internal_filter: 10us
filters:
- average_throttle: 10s
- filter_out: NaN
See :doc:`/components/sensor/total_daily_energy` for counting up the total daily energy usage
with these ``pulse_counter`` power meters.
.. note::
The ``pulse_meter`` sensor has an internal filter that is used to debounce the input signal. This filter is set to ``13us`` by default. To increase the safety margin, you can increase this value. For this you need to know the *minimum pulse width* that you can expect to see from your power meter within the expected load range.
The minimum pulse width threshold is determined by considering the upper limit of the *load* the meter is designed to handle, as well as the meter's *impulse constant* (x pulses / kWh). Here's the calculation involved:
- **Load Limit in Watts**: Establish the *upper load limit* that the meter is designed to measure. For example, if the limit is 16 kW (16,000 Watts), this becomes a reference point.
- **Pulse Rate Calculation**: Determine the pulse rate corresponding to this load limit. For this we need to know the impulse constant. In our example, the power meter has an impulse constant of 10000 pulses/kWh, resulting in 160000 pulses per hour at the maximum 16 kW load, i.e. 44.4 pulses/second.
- **Minimum Pulse Width Calculation**: Use the pulse rate to calculate the minimum pulse width threshold. In our example, with a maximum pulse rate of 44.4/sec, the minimum pulse width we expect to see is approximately 22.5 milliseconds. Choose a slightly smaller value than this to avoid missing pulses.

sensor:
- platform: pulse_meter
# ...
internal_filter: 20ms
If a technician shows up and he looks confused about what the heck you have done to your power meter, tell them about ESPHome 😉
Counting total generated energy
-------------------------------
When the total sensor is configured, ``pulse_meter`` also reports the total number of pulses measured. When used on a power meter, this can be used to measure the total transmitted energy in kWh.
.. code-block:: yaml
# Example configuration entry
sensor:
- platform: pulse_meter
# ...

name: "Electricity Total"
unit_of_measurement: "kWh"

- multiply: 0.0001 # (1/10000 pulses per kWh)
# - average_throttle: 10s
# - filter_out: NaN
(Re)Setting the total energy value
----------------------------------
Using this action, you are able to reset/set the total pulse count. This can be useful if you would like the ``total`` sensor to match what you see on your meter you are trying to match.
.. code-block:: yaml
api:
services:
- service: set_total
variables:
new_total: int
then:
- pulse_counter.set_total_pulses:
id: sensor_pulse_meter
value: !lambda 'return new_total * 1000;'
Tracking Total Daily Energy
---------------------------
Additionally you can also calculate the total daily energy generated, for which you can use the :doc:`Total Daily Energy </components/sensor/total_daily_energy>` using below configuration:
.. code-block:: yaml
sensor:
#(...)
- platform: total_daily_energy
name: 'Total Daily Energy'
id: sensor_total_daily_energy
power_id: sensor_energy_pulse_meter
unit_of_measurement: 'kWh'
state_class: total_increasing
device_class: energy
accuracy_decimals: 3
filters:
# Multiplication factor from W to kW is 0.001
- multiply: 0.001
time:
- platform: homeassistant
id: homeassistant_time
While you can in theory also do this with the home assistant `integration <https://www.home-assistant.io/integrations/integration/>`__ integration, the benefit of this is that it continues to integrate the power during times home assistant is unable to work with values, i.e. during updates, restarts and so on.
