Overview

This is a list of api URLs and some random thoughts I've been able to pull together from the interwebs and other functions we've been able to reverse engineer from the local gateway. This is not the [ Tesla Owner API] which you can find here: (https://tesla-api.timdorr.com) with a Python library that works nicely to control a Powerwall 2 here: (https://github.com/mlowijs/tesla_api).

Libraries / apps using this API

The following projects are known to be using portions of this API, and may be useful for those looking to interact with Powerwall devices:

Getting Started

A note about HTTPS and SSL Certificates

In a recent update to the Powerwall firmware (v1.20+) non-SSL requests (http) are no longer supported and queries will return HTTP/1.1 301 Moved Permanently. Unfortunately the certificate presented by the Powerwall is not signed by a root certificate authority as they are self-signed. This results in web browsers and tools like curl not accept it without it either being included as a trusted certificate or a specific action by the user to override the error.

You have three ways around a certificate error:

1) In web browser this will manifest itself as an error that the certificate is not trusted. To bypass simply click "details" (IE/Edge) or "Advanced..." (Firefox) and select continue.

2) With curl the --insecure or -k option will ignore the SSL certificate. This is ok, but it doesn't authenticate the device you are connecting to.

3) A better way is to export the Powerwall public certificate and add it to the local machine's trusted certificate list or just use the certificate in your curl request.

I recommend option 3 above.

In addition to the issues of validating the certificate itself, the Powerwall gateway also apparently uses SNI when serving the TLS certificate, and will simply abort the connection if the wrong hostname is presented via SNI when establishing the TLS connection. It can therefore only be accessed using a few set hostnames (and if you put its IP address in your local DNS or hosts file with a different name, it will likely not work).

Hostnames which are known to work to access a Powerwall:

Note that none of these names have any domain component. That means you must access the Powerwall as, for example, https://powerwall/. Something like https://powerwall.mycooldomain.net/ will not work (even if mycooldomain.net is configured to have the necessary DNS entry).

If you want to access your Powerwall using a name other than one of the above, you will likely need to do some custom hacking with your client's HTTPS/TLS settings to provide one of these names via SNI instead of the actual hostname (note that not all clients support this).

Here's what worked for me:

Step 1: DNS

Enable DNS lookups, on your local network, for one of the hostnames listed above (for example, powerwall) pointing to the device's IP address.

You can add this to your local DNS server as an A Record or /etc/hosts file or other DNS name resolution service.

For /etc/hosts add an entry that looks like this if your Powerwall gateway's IP was 192.168.99.99:

192.168.99.99 powerwall

Step 2: Get the certificate openssl s_client -showcerts -connect powerwall:443 < /dev/null | sed --quiet '/BEGIN CERTIFICATE/,/END CERTIFICATE/p' > cacert.pem

This grabs the certificate from the powerwall using the DNS entry you setup in step 1.

Step 3: use the certificate in your curl statements e.g. curl --cacert cacert.pem https://powerwall/api/status

If you get this error: curl: (51) SSL: no alternative certificate subject name matches target host name then the name you chose (teg or powerwall or powerpack) doesn't match what's in the certificate file and you'll need to check the certificate and perhaps do some googling to figure out the solution.

For the rest of the documentation, I will assume you copied the certificate and are using method C with the Powerwall's public certificate. If you didn't, just leave out the certificate --cacert cacert.pem portion and add -k.

Powerwall 2 Web UI

The web UI provides an instantaneous a 250-500ms average(?) power flow diagram an access to the wizard. Hit your local gateway IP with a browser, i.e. _https://powerwall/

You should see something like this:

GatewayUI

Wizard You can hit the "Login" link on this page and go through the setup (be careful what you change in the wizard).

Use case: One user is making this request to check new firmware available, and run the upgrade, approximately 30 minutes before switching to discharging (self_consumption mode with 5% reserve). Assumption is - we better upgrade firmware while battery is in standby mode, rather then letting gateway upgrade itself later, because it will stop battery possibly during peak hours for an upgrade. He noticed his gateway has self-upgraded during peak hours, resulting around 15 minutes stop of battery, which was an unpleasant surprise and extra cost. So, his idea was to force a new firmware check (and upgrade) when battery is not used:

Login

POST /api/login/Basic

_View the OpenAPI spec for this endpoint here https://vloschiavo.github.io/powerwall2/openapi/#/default/post_login_Basic_

To login to the Tesla Powerwall API, you will need either to know your Gateway serial number or your custom password.

If you do not have a custom password, your password will be the last 5 digits of your Gateway serial number. If you don't know your Gateway serial number, you can get it from the Tesla app by clicking on settings, My Home Info and it will be listed under "Powerwall Gateway".

In the request body, username can be set to "customer", the password is the last 5 characters of your Gateway serial number (or your custom password) and email, if included, can be left as an empty string.

Here is an example login using a serial number of T123456789. The password is: 56789.

Request: 

curl --cacert cacert.pem -s -i \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{"username":"customer","password":"56789"}' \
    https://powerwall/api/login/Basic

Response:

/api/operation

Change the Powerwall mode and Reserve Percentage

Note 1: Making changes to the Powerwalls via the Mobile application can take some time to go into effect. There's a rumor that states that the changes happen around 30 minutes past the hour. (Probably based on a cron job in Tesla's servers).

_Note 2: Setting a value is not sufficient to make the change. You must "save" or "commit" the configuration to have it go into effect. See the Config Completed section below._

Note 3: Once a value is changed and committed it is immediately in effect.

GET /api/operation

request: curl --header "Authorization: Bearer OgiGHjoNvwx17SRIaYFIOWPJSaKBYwmMGc5K4tTz57EziltPYsdtjU_DJ08tJqaWbWjTuI3fa_8QW32ED5zg1A==" https://192.168.xxx.xxx/api/operation

response: {"mode":"self_consumption","backup_reserve_percent":15}

POST /api/operation

The below request would set the battery mode to "Self-powered" and a "Reserve for Power Outages" to 20% (app value) using the token retrieved from the authentication example.

request: curl --header "Authorization: Bearer OgiGHjoNvwx17SRIaYFIOWPJSaKBYwmMGc5K4tTz57EziltPYsdtjU_DJ08tJqaWbWjTuI3fa_8QW32ED5zg1A==" -X POST -d '{"mode":"self_consumption","backup_reserve_percent":24.6}' https://192.168.xxx.xxx/api/operation

response: {"mode":"self_consumption","backup_reserve_percent":24.6}

Valid Modes:

  1. self_consumption
  2. backup
  3. autonomous (aka Time of Use (TOU) as reported by dlieu on the teslamotorsclub.com forums)
  4. scheduler aka Aggregation - This seems like it is not supported now.

The JavaScript constant in the code of mobile client for Android has the following options:

OperationModes = 
{SELF_CONSUMPTION: "self_consumption",
TIME_OF_USE: "autonomous",
BACKUP: "backup",
AGGREGATION: "scheduler"}

There also is an option to set the max PV Export power in kW. I'm not 100% sure what that does but I could guess (Time of use?). Mine is currently set to null (probably because time of use isn't enabled on my system yet (as of April 2018). You can omit this key/value pair from the POST.

{max_pv_export_power_kW: null, mode: "self_consumption", backup_reserve_percent: 24}

Note the difference in the app value (20%) versus the value we set via the local API (24%). You can use these formulas for the conversion:

From app value to API value: $$\frac{19}{20}x+5$$

From API value to app value: $$\frac{20}{19}x-\frac{100}{19}$$

POST /api/v2/islanding/mode

Sets whether the powerwall is on or off grid. Change the value in the POSTed data to change to off-grid (intentional_reconnect_failsafe) or on-grid (backup).

Switch to Off-grid mode

Request:

curl --header "Authorization: Bearer OgiGHjoNvwx17SRIaYFIOWPJSaKBYwmMGc5K4tTz57EziltPYsdtjU_DJ08tJqaWbWjTuI3fa_8QW32ED5zg1A==" -X POST -d '{"island_mode":"intentional_reconnect_failsafe"}' https://192.168.xxx.xxx/api/v2/islanding/mode

Response:

{
    "island_mode": "intentional_reconnect_failsafe"
}

Note that subsequent calls to /api/system_status/grid_status/ will return grid_status: "SystemIslandedActive" once the system is in off-grid mode.

Request:

curl --header "Authorization: Bearer OgiGHjoNvwx17SRIaYFIOWPJSaKBYwmMGc5K4tTz57EziltPYsdtjU_DJ08tJqaWbWjTuI3fa_8QW32ED5zg1A==" -X POST -d '{"island_mode":"backup"}' https://192.168.xxx.xxx/api/v2/islanding/mode

Response:

{

jasonacox - The binary file is a protobuf payload. It includes all devices including metrics for string data. Without the proto schema, the protoc tool can decode the raw file (some information will be missing without the schema):

protoc --decode_raw < vitals

The output represents the data in { ... } groupings with number prefixing and key values in hex, strings or 1/0 boolean. Thanks to @brianhealey we have a working tesla.proto file. This can be used to decode the protobuf payload (e.g. protoc --python_out=. tesla.proto).

A decoded output example /api/devices/vitals from pypowerwall (pw.vitals()) looks like this:
