We are working full-time on this migration.
Vehicles on which the old API has stopped working will display an error on the Charge HQ home page. We should have a solution for these vehicles next week. Stay tuned for updates.
UPDATE 2023-11-21
We are making progress on integrating to the new API.
Tesla have advised that different plans with different rate limits will be made available, possibly announced by the end of 2023. When these plans are announced we will comment on how the rate limits will impact Charge HQ.
A small number of vehicles (around 0.5%) are now rejecting commands from Charge HQ via the unofficial API. These vehicles can not be used with Charge HQ currently. See this status event for details.

Current status:
ORIGINAL POST
Charge HQ like all other third party Tesla apps, has been using the unofficial Tesla API. This is the same API that was built to support the Tesla mobile app but was never designed for third party use.
In October 2023, Tesla announced they would be introducing an official third party API with a view to sunsetting use of the unofficial API at some point in future. This is an exciting development which indicates a long term commitment to working with third parties such as Charge HQ via API based services.
The new API offers significant improvements in security and may enable further feature development not currently possible. The new API also includes some changes to messaging rate limits - the details of this are yet to be determined.
Charge HQ is actively working on a transition. Updates will be posted on this guide, and via emailed product updates as we progress.
