Charge HQ

Tesla hasn't even announced API pricing yet. The developers are jumping the gun a bit.

I hope there is a free ‘hobby’ tier, which maybe limits API calls to 10 per day or something. Enough to let single users script what they need, but completely inadequate for anyone wanting to develop a public App for monetisation purposes - in which case it is totally right that they pay for API access.

That would be nice.

Not so far, you have to have a business license and a website for them to confirm you are serious

If all you want is charge on solar like features you can roll your own with BLE (bluetooth), with Raspberry Pi Zero/Laptop or similar with features from the 'tesla control' app provided in the SDK from Tesla. No fleet API communications are necessary, or internet connection even at all.

Just run evcc which is exactly what I have done.

Run what?

Run what?

evcc - Solar Charging ☀️🚘 - Connects Your EV Charger With Your PV System

evcc ermöglicht es, Elektrofahrzeuge mit möglichst viel selbsterzeugtem Solarstrom zu laden.

evcc.io

It's an open source EV solar charge system you can run locally on your own device.

Seems like BLE is not quite plug and play yet with evcc.io.

Implement Tesla BLE support · evcc-io evcc · Discussion #14252

Since Tesla introduced severe limits for their cloud API calls, it's not really usable for solar charging anymore. The same API can however be used over BLE (Bluetooth Low Energy). I have tried it ...

Maybe @Borgy can advise what they have done here. The old API still works under some conditions, I don't think you can register a new key/token but old ones continue to be able to be refreshed.

I had Teslamate running anyway and have an ocpp charger so was simple to switch from chargehq to the evcc. The pace of development of this project I’m not surprised. 2 killer features for me are Amber price forecasts and charge planner.

Now I only need something to deal
with demand tariffs but may be possible with the site circuit limits and manipulating the site metering data during the demand period.

Not if you have a legacy S or X.
