Tesla Fleet Needs device_class type Energy

[eddy-r]

The problem

When configuring the Energy tab, adding a Grid Consumption sensor does not list any sensor from the Tesla Fleet sensors. Following the help link (https://www.home-assistant.io/docs/energy/faq/#troubleshooting-missing-entities) explains that power is measured in Watts and energy in kiloWatt-hour.

Tesla Fleet provides sensors for grid_power, load_power, solar_power, and battery_power with a unit of measure of kW and a device_class of power.

In order to use the information from these sensors in the Energy tab, the device_class needs to be energy. The state_class must be total or total_increasing. The unit_of_measure should be kWh.

These sensors cannot currently be used in the Energy tab as they are.

Hey there @bre77, mind taking a look at this issue as it has been labeled with an integration (tesla_fleet) you are listed as a code owner for? Thanks!

@eddy-r the information provided by Tesla is power, not energy. Changing the device_class will make it show up in the energy dashboard, but the information will be incorrect.

You need to create an integration helper to estimate the energy value from the power. https://www.home-assistant.io/integrations/integration/#energy

[eddy-r]

@Bre77 exactly right, the information provided by Tesla is power, but a full integration for Home Assistant should provide the data points for useful features within Home Assistant. If this have been posted under feature request, please feel free to move it.

I have it working and showing data in the Energy tab, but it took some delving into the inner workings of the system. For instance, Tesla Fleet provides power as a single number, with a positive number meaning flow of power away from the given source (whether it's the grid, battery, or panels), and a negative value being power flowing towards the source of the reading. Taking this and producing a straight-forward integration helper that also shows positive and negative kWh is not what the Energy tab expects. First, I had to split the data from the grid and battery power into positive-only values.

For example, grid_power in the positive value became grid_import_kw. grid_power in the negative became a positive value for grid_export_kw. grid_import_kw and grid_export_kw then have to be used in the integration template to create grid_input_kwh and grid_export_kwh.

To extract the positive value from grid_power I wound up using {{ [ states('sensor.my_home_grid_power')|float(0), 0.0 ] | max }}, which because I am not fluent in the language used, I had to adapt from a search result. The method to convert a negative value into a positive value I wound up using was {{ [ ( -1 * states('sensor.my_home_grid_power')|float(0)), 0.0 ] | max }}.

Rinse and repeat for the battery, and create an integration helper for the solar panels, and it was done, but only after trial and error. After setting the Device section to the Tesla Fleet device name ("My Home" by default), all of these show up as entities and sensors for the device.

Isn't it possible to set this up programmatically so that users don't each have to go hunting for how to do those steps?

It sure is, but as far as I am aware Home Assistant has rules against me doing it in the integration itself. I've asked the question on Discord because if I am allowed to then I defintely will for Tessie, Teslemetry, and Tesla Fleet.

update: there was a communication issue with gateway seems to be functioning but the kwh data sensor isn't reporting any data even though the fleet sensor shows it

i thought i had this setup properly last night but because it was night i assumed thats why solar value was 0. i'm getting the energy from grid sensor just fine but still no solar readout, so it seems its properly portioned just not getting solar info? (complete newb to HA, just installed green box yesterday)

sensor:

• platform: integration source: sensor.energy_site_solar_power # <-- the actual name of your sensor name: tesla_solar_panels_kWh unit_prefix: k unit_time: h round: 2

• platform: integration source: sensor.energy_site_grid_power # <-- the actual name of your sensor name: APS_usage_kWh unit_prefix: k unit_time: h round: 2

Hey - so total novice first time user of HA which I primarily purchased for energy tracking to start with. I have the Tesla Fleet connected and obviously ran into the same problem as I was trying to setup the energy dashboard. I really tried my best to understand what was done in this thread but honestly getting nowhere. Would it be too much to ask for steps to create these sensors so I could use them in the energy dashboard? Thanks.

No that's a really good idea, I'll add a section to the documentation.

[jeegnesh-patel]

That would be so awesome and maybe stop me returning my HA green box

So for the silly, does that mean I will find it at the bottom of https://www.home-assistant.io/integrations/tesla_fleet once you add it? (Please write for the stupid)
