Question 1

Command Credits System and Usage

Accepted Answer

Command credits are Teslemetry's pay-per-use system for vehicle commands. Since Tesla charges Teslemetry for every command sent through the Fleet API, command credits allow Teslemetry to pass these costs directly to users based on their actual usage.

Understanding Command Credits

Command Credit Costs

| Action | Credit Cost | Notes | | ---- | | Standard vehicle command | 1 credit | Includes lock, unlock, climate, flash lights, etc. | | Vehicle data refresh | 2 credits | Forces a server-side data refresh | | Vehicle wake up | 20 credits | Most expensive due to Tesla's pricing |

Pricing: 2000 command credits = USD $2.50 ($0.00125 per credit)

Credits Do NOT Reset Monthly

Important: Command credits do not expire and do not reset with your subscription renewal. Once purchased, they remain in your account until used or until you delete your account.

Frequently Asked Questions

Why am I getting "Account has insufficient command credits" errors?

This error occurs when you attempt to run a command but your account does not have enough credits. This can happen because:

You have run out of credits - Check your balance at teslemetry.com/console
Auto top-up is disabled - Enable auto top-up to automatically purchase more credits when you run low
High automation usage - Frequent automations can consume credits quickly

Solution: Purchase additional command credits through the Teslemetry console

Question 4

Tesla Authentication and Reauthentication

Accepted Answer

This guide covers how authentication works between Teslemetry and Tesla, common authentication issues, and step-by-step instructions for resolving them.

How Authentication Works

Teslemetry uses Tesla's OAuth 2.0 authentication system. When you log in at teslemetry.com/login, you are redirected to auth.tesla.com where you enter your Tesla username, password, and two-factor authentication (if enabled). Teslemetry never sees or stores your Tesla password.

Key points about the authentication system:

OAuth 2.0: Teslemetry receives tokens from Tesla that grant access to your account based on the scopes (permissions) you approve
Automatic Token Refresh: Access tokens are refreshed automatically by Teslemetry's scheduled tasks every 8 hours
Token Revocation: Tokens are automatically deleted if they have been revoked by Tesla

Frequently Asked Questions

Why did I receive an authentication failure email from Teslemetry?

This notification is sent when Teslemetry can no longer successfully authenticate with Tesla on your behalf. The most common causes are:

Password Change: You changed your Tesla account password
Access Revoked: You revoked Teslemetry's access at auth.tesla.com
Tesla Backend Issues: Tesla occasionally has authentication problems that affect all third-party apps
Token Expiration: Your refresh token may have expired or become invalid

Question 5

Virtual Key Pairing and Installation Issues

Accepted Answer

The Teslemetry virtual key is a public key that enables secure communication between your Tesla vehicle and Teslemetry. It is required for Fleet Telemetry (real-time streaming data) and command signing (sending commands to newer vehicles).

How to Install the Virtual Key

Step-by-Step Instructions

Open the Tesla app on your smartphone
Select the specific vehicle you want to pair (the vehicle must be displayed on screen)
Open this link on your smartphone: https://tesla.com/_ak/teslemetry.com
Follow the instructions in the Tesla app

Important: If the Tesla app does not open immediately when you click the link, the process has not worked. You must have the Tesla app open with your vehicle selected before clicking the link.

Alternative Method

If another user with vehicle access needs to install the key, they can use: https://teslemetry.com/key

Frequently Asked Questions

Why does virtual key pairing keep timing out?

Answer: Virtual key pairing timeouts typically occur when the Tesla app is not properly prepared for the process. To resolve this:

Question 6

Powerwall Control and Limitations

Accepted Answer

This article covers common questions about controlling Tesla Powerwall systems through Teslemetry, including the Tesla Fleet API limitations, workarounds, and troubleshooting tips.

Overview

Teslemetry provides control over Tesla Powerwall systems through the Tesla Fleet API. However, there are important limitations to understand, as Tesla restricts certain capabilities.

Common Questions

Can I force my Powerwall to discharge the battery?

No, there is no direct API command to force discharge a Powerwall. This is a Tesla Fleet API limitation, not a Teslemetry limitation.

Only Virtual Power Plants (VPPs) have the ability to force discharge a Powerwall through their special API access.

Workaround - Tariff Price Manipulation: You can encourage discharge behavior by manipulating the Time of Use (ToU) tariff settings. When the export/sell price exceeds the import/buy price by a sufficient margin, the Powerwall will autonomously decide to export to the grid.

How do I force charge my Powerwall?

Set the backup reserve to 100%. This is the only reliable method to force the Powerwall to charge from any available source (grid or solar).

In Home Assistant, you can use the number.{powerwall_name}_backup_reserve entity and set it to 100.

What backup reserve percentages can I set?

The backup reserve can be set to:

0% to 80% - Any value in this range
100% - For force charging

Note: Values between 81% and 99% are not supported by
