TEDAPI - Local API for Powerwall

[jasonacox]

How to use the latest pypowerwall to connect to the Powerwall gateway TEDAPI interface:

First, you need to create a network route to get to that endpoint via your local network (or direct connect to the Gateway's WiFi access point):

# Change 192.168.0.100 to the lP address of the Powerwall gateway on your LAN

# Linux Ubuntu and RPi - Can add to /etc/rc.local for persistence 
sudo ip route add 192.168.91.1 via 192.168.0.100

# MacOS 
sudo route add -host 192.168.91.1 192.168.0.100 # Temporary 
networksetup -setadditionalroutes Wi-Fi 192.168.91.1 255.255.255.255 192.168.0.100 # Persistent

# Windows - Using persistence flag - Administrator Shell
route -p add 192.168.91.1 mask 255.255.255.255 192.168.0.100

Next, find the Gateway WiFi password that is typically located on the QR code on the gateway itself. Use that to connect with something like this:

Import pypowerwall

PW_HOST=“192.168.91.1"
PW_GW_PWD=“GATEWAY_PWD"

pw = pypowerwall.Powerwall(PW_HOST, gw_pwd=PW_GW_PWD)

print(f"mode: {pw.mode} - tedapi: {pw.tedapi_mode}")
pw.tedapi.get_din()
pw.power()

Checking in some details here:

My installation consists of one Gateway 3 and three Powerwall 3 units. The Tesla One account is connected to my primary PW3. I looked and I don't see any Wifi information or the like on the Gateway 3. The PW3 is hardwired and on the network as 192.168.90.2.

The Tesla One account shows the PW3 connected on cellular, Wifi, and Ethernet.

I cite all of this because the instructions here say to connect to the gateway, but I don't see that information. My primary PW3 appears to be handling that role, and I'm not sure if that's new, evolutionary, etc.

When I try to use the tedapi (option 4), connecting to the primary PW3 with the Wifi password as the gateway password gives me back an Access Denied.

I'm wondering if things have changed here and the comments have not yet caught up,

Running version 0.11.1.

HI @JohnJ9ml - I can't tell from your details, but are you connecting to 192.168.90.2 directly over your LAN? If so, that is the problem and you will get access denied because the TEDAPI requires you to be connected to the WiFi access point (not hardwired) at 192.168.91.1.

Since your PW3 is on your LAN, you can create a static route (via 192.168.90.2) to get to that endpoint using a script like this:

https://github.com/jasonacox/Powerwall-Dashboard/blob/main/add_route.sh

Once you have that, your host should be able to ping 192.168.91.1 and you can run the code above to access your system.

Also, there is a built in test:

python3 -m pypowerwall.tedapi

I apologize for not fully internalizing what was being said here.

Somehow, my system being hardwired just didn't seem to convince me I really needed to find the IP address of the Wifi connection - it almost seems a bit unfathomable that the tedapi endpoint is evidently not exposed on a hardwired connection?

I am now connected. One very small pickup from the readme for pypowerwall. For the Programming with pyPowerwall section, the tedapi example has a typo in the gateway password option:

pw = pypowerwall.Powerwall(host,password,email,timezone,gw_pw=gw_pw,auto_select=True)

Should be gw_pwd

It's right in the quick test code elsewhere, but wrong in the readme.

Thanks for the help and for getting me through one obtuse concept. It still seems a bit strange....

Thanks for the tip! I updated the README: 2c93ce9
