Tariff Automation (Amber & GloBird)

This article covers frequently asked questions about syncing your electricity provider's prices to your Tesla Powerwall using Teslemetry's tariff automation feature. Two providers are supported: Amber Electric and GloBird Energy.


This feature is currently in beta, and is subject to change or removal.



Overview


What is tariff automation?


Teslemetry offers a feature that syncs your electricity provider's prices directly to your Tesla Powerwall. This allows your Powerwall to make intelligent decisions about when to charge from the grid, discharge to the grid, or use stored energy based on real-time market prices. Amber Electric and GloBird Energy are both supported.


Where can I find the tariff automation integration?


Tariff automation is accessed at https://teslemetry.com/console/utilities/tariff. From this page, you can:


  • Choose your provider (Amber Electric or GloBird Energy)
  • Enter your provider API key
  • Select which energy site(s) to sync (GloBird has its own site picker)
  • View a real-time price graph
  • Enable or disable the price sync feature


What does the integration actually do?


The integration syncs your provider's electricity prices to your Powerwall's tariff configuration every 5 minutes. This allows your Powerwall to make autonomous decisions in Time-Based Control mode.


Important: The price sync only works when your Powerwall is in Autonomous (Time-Based Control) mode.



Configuration


How do I configure tariff automation with my Powerwall?


  1. Get your provider API key: Log into your Amber Electric or GloBird Energy account and generate an API key
  2. Configure Teslemetry: Go to https://teslemetry.com/console/utilities/tariff, choose your provider, and enter the API key (for GloBird, also select your site in its site picker)
  3. Set your Powerwall to Autonomous mode: Open the Tesla app and select "Time-Based Control"
  4. Verify the sync: Check the real-time price graph on the Teslemetry console


How frequently do the prices sync?


Prices are synced to your Powerwall every 5 minutes.



Price Discrepancies


Why are the import/export prices in the Tesla app different from my provider's app?


While we have made efforts to get price updates from providers as soon as possible, it is expected that the Teslemetry updates will occur slower than the provider's own systems. You may notice small discrepancies in this instance. As of February 7 2026 the Amber sync uses the same AEMO based forecasts as the Amber app, rather than the CSIRO advanced predictions which were used originally.



Revoking the Integration


How do I revoke tariff automation and restore default Tesla app settings?


To disable the price sync:


  1. Go to https://teslemetry.com/console/utilities/tariff
  2. Set the mode to "Off"
  3. Once disabled, use the Tesla app to set your tariffs however you prefer



SmartShift and VPP Considerations


What happens if I am on SmartShift (Amber)?


When enrolled in SmartShift:


  • Amber can control your Powerwall for VPP events
  • Some settings may be hidden from the Tesla app
  • You can still change these settings via the Teslemetry API
  • SmartShift and Teslemetry tariff sync can coexist, but be aware of potential conflicts
