Option to specify Unit of Measure for var_PV and var_load
BJReplay opened this issue · comments
Describe the bug
Not strictly speaking a bug, but the template provides hints of things to provide to document the issue, so I'm using the bug report template.
I have existing data (approximately 16 months) for load and solar production in kW (and kWh).
I can (and have) set up template sensors to convert kW to W, but they only have data from the moment that I set them up an hour or so ago this afternoon while setting up EMHASS.
The issue is that if I want to (and I do want to) use the machine learning forecaster module, there is no way (that I can see) of training it on my historical data.
To Reproduce
Steps to reproduce the behavior
- Create a template sensor based off the native kW sensor that converts the reading (load or PV production) from kW to Watts as required by EMHASS
Expected behavior
- Ideally the history of the kW sensor would be available for EMHASS to use, but that's not the way HA works.
- If EMHASS allowed you to specify the Unit of Measure for var_PV and var_load where existing sensors were in kW, it would avoid this issue.
For example:
# Configuration file for EMHASS
retrieve_hass_conf:
freq: 30 # The time step to resample retrieved data from hass in minutes
days_to_retrieve: 365 # We will retrieve data from now and up to days_to_retrieve days
var_PV: 'sensor.blah_s_powerwall_solar_power' # Photovoltaic produced power sensor
var_PV_UoM: kW
var_load: 'sensor.blah_s_powerwall_load_power' # Household power consumption sensor (deferrable loads should be substracted)
var_load_UoM: kWScreenshots
Base Sensor in kW
