agile-powerwall's Introduction

Agile Powerwall

Home Assistant Pyscript-based integration that uploads dynamic pricing to Tesla Powerwalls.

This is primarily designed to sync Octopus Agile prices to Tesla Powerwalls. It glues together two pieces of software

using

Pyscript.

Installation

Install Home Assistant Octopus Energy integration.
Install Pyscript integration.
Unzip the release zip into the Home Assistant directory /config.
Add Pyscript app configuration:

pyscript:
    apps:
        powerwall:
            email: <username/email>
            refresh_token: <refresh_token>
            tariff_name: Agile
            tariff_provider: Octopus
            import_mpan: <mpan>
            import_tariff_breaks: [0.10, 0.20, 0.30]
            import_tariff_pricing: ["average", "average", "maximum", "maximum"]
            plunge_pricing_tariff_breaks: [0.0, 0.10, 0.30]
            plunge_pricing_tariff_pricing: ["average", "maximum", "maximum", "maximum"]

Optionally, create an input_text helper called powerwall_tariff_update_status if you want to see status messages.

Configuration

email: E-mail address of your Tesla account.

refresh_token: One-off refresh token (see e.g. https://github.com/DoctorMcKay/chromium-tesla-token-generator)

tariff_name: name of the tariff.

tariff_provider: name of the tariff provider.

import_mpan: MPAN to use for import rates

export_mpan: MPAN to use for export rates if you have one

import_tariff_breaks: Powerwall currently only supports four pricing levels: Peak, Mid-Peak, Off-Peak and Super Off-Peak. Dynamic pricing therefore has to be mapped to these four levels. The import_tariff_breaks represent the thresholds for each level. So, by default, anything below £0.10 is mapped to Super Off-Peak, between £0.10 and £0.20 to Off-Peak, between £0.20 and £0.30 to Mid-peak, and above £0.30 to Peak. (You can use import_tariff_breaks: jenks to calculate optimal breaks, but this may not give optimal behaviour.)

plunge_pricing_tariff_breaks: similar to above, but applied if there are any plunge (negative) prices.

import_tariff_pricing: determines how to calculate the price of each import pricing level from the actual prices assigned to a level.

plunge_pricing_tariff_pricing: similar to above, but applied if there are any plunge (negative) prices.

export_tariff_pricing: determines how to calculate the price of each export pricing level from the actual prices assigned to a level.

import_standing_charge: sensor name or value.

export_standing_charge: sensor name or value.

schedule_type: one of:

week - current day rates are used for the week (default).

weekend - same as week, but when possible, current day rates are used for midweek/weekend and next day rates are used for weekend/midweek.

multiday - current day rates are used to span one part of the week, and next day rates are used to span the rest (not compatible with in-app editor).

maintain_history: keep previous schedules, don't calculate schedule afresh (default: false).

Computed thresholds

As well as numeric thresholds, the following computed thresholds are also supported:

lowest(num_hours): sets the threshold at the price to include the cheapest num_hours hours.

highest(num_hours): sets the threshold at the price to exclude the most expensive num_hours hours.

states(sensor_name): uses the value of the specified sensor as a threshold.

state_attr(sensor_name, attr_name): uses the value of the specified state attribute as a threshold.

e.g.:

            import_tariff_breaks: ["lowest(2)", 0.20, 0.30]

Pricing formulas

average: the average of all the prices. If the average is negative, it is set to zero.

nonNegativeAverage: the average of all the prices. If a price is negative, it is taken to be zero.

minimum: the minimum of all the prices. If the minimum is negative, it is set to zero.

maximum: the maximum of all the prices.

agile-powerwall's Issues

Octopus rates being downloaded - Powerwall utility rate plan not being updated

Expected Behaviour:

Half-hourly rates for import and exported are downloaded from the Octopus API(s)
Powerwall utility rate plan is updated with these, in-line with the pyscript powerwall app configuration
A DEBUG log entry of "Powerwall updated" should be visible in the logs upon completion

Actual Behaviour:

Half-hourly rates for import and exported are downloaded from the Octopus API(s)

Powerwall utility rates have not been updated in the Tesla app -
No errors in the logs, no successful message in the logs

I have regenerated the Tesla refresh token in case this was causing a failure and validated the other information in the app configuration.

Noting the comment from Issue 1:
"One thing that comes to mind is I had issues with the release version of teslapy. I had to place a copy of head under config/pyscript_packages. I also renamed the directory from teslapy to teslapy_latest and updated the imports to teslapy_latest to guarantee that version was being used."

Originally posted by @pulquero in #1 (comment)

I was not able to determine what this referred to, I'm not a developer and so if you can be more specific about what's required, I'm happy to give it a try.

I am running the latest files and have updated the config to include export MPAN.

Import Errors on first run

Firstly thank you for your efforts - the idea of this is amazing for an Octopus/Powerwall user.

Home Assistant - Fresh install with default integrations
HACS - Fresh install

Octopus Energy - Fresh install, 2 devices 41 entities all working correctly
PyScript - Fresh install

config/configuration.yaml:

# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
pyscript: !include pyscript/config.yaml

I added an include after trying the config in the config/configuration.yaml without success

Jenkspy fails "because it is not a valid package"

Hi Mark,

2024-01-30 18:59:01.577 DEBUG (SyncWorker_4) [custom_components.pyscript] Ignoring 'git+https://github.com/pulquero/jenkspy' because it is not a valid package

I tried a couple of basic things just to test (like specifying the branch) but no luck.

Exception in previous day rates - 500 Server error in API

Hi,
I experienced some quirkiness over the last few weeks and so I left HA off overnight and restarted this morning with debug on. I noted the errors below:

2024-03-19 04:50:21.217 ERROR (MainThread) [custom_components.pyscript.apps.powerwall.refresh_previous_day_rates] Exception in <apps.powerwall.refresh_previous_day_rates> line 76:
tariff_data=tariff_data
^
HTTPError: 500 Server Error: upstream internal error for url: https://owner-api.teslamotors.com/api/1/energy_sites/*************142/time_of_use_settings

It's worth saying that the utility rate plan for import appears to have updated correctly but that export has not (all show 0.00). It's logical that this might relate to the fact that HA was off overnight and therefore previous day rates is throwing an exception because it doesn't have any previous day rates but this is a complete guess on my part.

Config (unchanged since we got it all working):

allow_all_imports: true
apps:
  powerwall:
      email: "le******@******.com"
      refresh_token: "******"
      tariff_name: Tracker
      tariff_provider: Octopus
      import_mpan: "*************"
      export_mpan: "*************"
      tariff_breaks: [0.10, 0.20, 0.30]
#      tariff_breaks: jenks
      import_tariff_pricing: ["average", "average", "maximum", "maximum"]
      export_tariff_pricing: ["average", "average", "maximum", "maximum"]
      plunge_pricing_tariff_breaks: [0.0, 0.10, 0.30]

Thanks in advance

Export rate update fails with error

Export rates are downloaded and powerwall updated

Removing the export_mpan from the config allows the import process to run as normal.

Note:
From the looks of things, looks like import data is from 00:00 to 23:00 but export data is from 00:00 to 24:00. For now, remove the export_mpan to see if the rest works and i'll work on a fix for exports.
