Powercalc - Virtual power sensors

arganto · July 24, 2022, 6:47am

Can you explain, what you want to say with this?

First of all: Reload UI-pagen. Often the UI shows entities from brwoser cahce, which are not available anymore.
Secondly: If they are created from integration and still bound to integration, you will not be able to delete, even if you have renamed them.

I am trying to create a virtual sensor for my thermostat and am getting an error in the log. What does mean?

sensor:

platform: powercalc
entity_id: climate.kitchen_warm_floor
fixed:
power: 1600

Logger: custom_components.powercalc.sensors.power
Source: custom_components/powercalc/sensors/power.py:150
Integration: Powercalc (documentation, issues)
First occurred: 20:55:11 (2 occurrences)
Last logged: 20:55:11

climate.kitchen_warm_floor: Error setting up calculation strategy: This entity can only work with ‘states_power’ not ‘power’

bramski · July 24, 2022, 4:09pm

Only power is only allowed for devices which have a binary state (on/off).
A climate device can have different modes (can also be different per device).
So you’ll have to use states_power: like this. Also see the readme for other examples.

- platform: powercalc
  entity_id: climate.kitchen_warm_floor
  fixed:
    states_power:
      heat: 1600
      #other states which you want to handle

Thanks, it works!

mhanley05 · July 25, 2022, 2:03am

For the UI mode is it possible to use an existing power sensor?
ex:

state: 26.9
state_class: measurement
meter_type: 1
meter_type_name: ELECTRIC
unit_of_measurement: W
device_class: power
friendly_name: 'Living Room Light: Electric Consumption [W]'

I have tried the following in the template section of the UI:

"{{states('sensor.living_room_dimmer_switch_electric_consumption_w')}}"
{{states('sensor.living_room_dimmer_switch_electric_consumption_w')}}

It doesn’t seem to be tracking as a utility meter or reading the power sensor.

Watt is the unit of power whereas kilowatt-hour (kWh) is the unit of energy

This PR brings a config flow which allows you to configure sensors with the GUI.… I tried to focus on the most used options to not clutter the UI and keep things simple for users. When you need advanced options which are not exposed in the GUI yet you can still use the YAML way. I have no plans to remove YAML, this will stay and give power users the possibilities they want.

From today I have 4 errors when I do a config check:

I’m on HA version 2022.7.6.
Has anyone an idea?

bramski · July 25, 2022, 1:12pm

Which version of powercalc? When you have updated to v0.24.0 or v0.24.1, there is a know issue which is probably fixed on master branch already. Will release v0.24.2 later today.
The issue was reported here: https://github.com/bramstroker/homeassistant-powercalc/issues/902

bramski · July 25, 2022, 1:26pm

@mhanley05 I have tried to focus on most used options in the GUI to not clutter it too much.

When your goal is to create an energy meter (kWh) and/or utility_meter for this existing power sensor, I suggest you stick to the helpers HA supplies out of the box (Settings → Devices & Services → Helpers → Create helper). Use “Integration - Riemann sum integral” for the energy sensor, “Utility meter” for the utility meters.

BernieV · July 25, 2022, 1:30pm

I’m on v0.24.0. As I speak I can now upgrade to v0.24.1.
I wil try this, thx for the info.

bramski · July 25, 2022, 1:38pm

It’s not fixed in v0.24.1 yet, you’ll probably hit the same issue there. Looks for most users these releases are broken. You can try installing master branch with HACS. Click redownload and enable beta releases. That will allow you to choose master.
When you can confirm that this solves the issue I will release v0.24.2. I don’t want to make another broken release, so I want some confirmations from users first that it is really solved.

bramski · July 25, 2022, 1:53pm

@BernieV Just released v0.24.2 which should resolve the issues

BernieV · July 25, 2022, 2:05pm

Thx, problem solved with release v0.24.2!

DirkStorck · July 26, 2022, 7:00am

Hi,
i have updated to v0.24.2. Everything is working fine so fare except one thing. I have groups of plugs witch have energy- and power-sensors created but only the energy-sensor shows a value

here the energy-sensor

and here the power-sensor

on the energy-sensor screenshot I can see the entities on the screenshot of the power-sensor not.

That is not the case if I look at a power-sensor of my light group for example.

Here are entities in the attribute section.

Here is my config:

Hi,

I have two shelly plugs in my room. Is it normal that powercal uses the “total consumption” of that device? The problem is that than the energysensor of that group uses the readings from past days even those from last month

The month has just started I have already 13,55 kWh ?!?

here are the readings from one plug

here is my config of that room

This is expected behaviour. The grouped energy sensor just sums all the energy sensors together. When you have a “real” existing energy sensor which is part of the group and that already has an value (from the past) you need to have a look if you can reset is somehow. I am pretty sure the shelly plugs allow the kWh meter to be reset from the Shelly App. But I am not at home atm so cannot check.

DirkStorck · August 2, 2022, 10:03am

Thanks for the information. Will have a look into that

DirkStorck · August 2, 2022, 10:39am

Looks like there is sadly no way to reset only the power consumption… only a factory reset

Than I have to live with that
