Gen3 Wall Connector API?

[btenison]

I noticed that the Gen 3 wall connector responds to most URLs (example http://<ip address>/status) with a 404, but noticed that if I try something like this:
http://<ip address>/api/1/status
I get no response. I'm wondering if there is an API underneath this thing that can be polled. Just wondering if anyone had worked on this at all?

Ah ha!
/api/1/vitals

Gotta dig some more!

 

[PCRover]

Keep us updated!

 

[btenison]

Two more:
http://<IP address>/api/1/wifi_status
http://<IP address>/api/1/lifetime

it's a start...

Awesome find @btenison!

Definitely subscribed

http://<IP address>/api/1/version

 

[btenison]

Nice one @sorbl! Didn’t find that one. I’ve been trying to document:
http://<IP address>/tedapi/v1

but I think they may have locked that down to only the config/setup WI-FI ssid/network.

Thanks for this! Hoping there's some way to control (start/stop or even the amperage) the charging via an API. That would be awesome to maintain a charging level to only charge what solar is generating instead of pulling back off the batteries or grid!

 

[cgul]

Awesome. Confirmed all of those. Also looking at the code in the tedapi to see if I can discover anything.

What's the difference between a gen 2 and gen 3 connector? Used gen 2 on TMC for $300.

http://<IP address>/api/1/lifetime

this is neat to see. Total energy_wh and number of cycles.

Hi everyone,

All these are very interesting news. Found also this:
Tesla Wall Connector Gen 3 RESTful
which is somewhat the same

Could it be possible to make a Git with all these data so we can have a clear informations source and eventually contribute?
Or some other kind of repositiry with all the available data ?

Thanks

I wonder why Tesla hasn't added the Wall Connector the app yet. This information is awesome and really helpful in understanding how much it's costing to charge at home.

What are you using to create these graphics?

I'm using InfluxDB Cloud to present and store this data. The data is gathered using Telegraf and shipped to my cloud account. The volume of data is relatively small so it should be all free. Once you have a InfluxDB cloud account I have a template that can be add which creates the Telegraf configuration, dashboards, buckets, variables. You should only need to run Telegraf within your network with the right environment variables set.

Here is a Gist to the InfluxDB template

The Vitals API is reporting current & voltage A, B, and C. Does anyone know what these refer to? I am assuming these are for three-phase power, but I have 240V North American split-phase, but I see values in A, B, & C for both Voltage & Current. And then there's CurrentN.

{"contactor_closed":true,"vehicle_connected":true,"session_s":19173,"grid_v":240.0,"grid_hz":59.870,"vehicle_current_a":4.0,"currentA_a":1.2,"currentB_a":1.3,"currentC_a":1.3,"currentN_a":1.2,"voltageA_v":244.4,"voltageB_v":244.3,"voltageC_v":120.1,"relay_coil_v":6.1,"pcba_temp_c":14.1,"handle_temp_c":12.1,"mcu_temp_c":18.6,"uptime_s":1372560,"input_thermopile_uv":-172,"prox_v":1.5,"pilot_high_v":0.1,"pilot_low_v":0.1,"session_energy_wh":0.000,"config_status":5,"evse_state":11,"current_alerts":[]}

Does anyone know what these mean?

I use Teslamate, which is open source. I should reach out to the developer(s) and see if they can add me to the project in GitHub. It would be great to add the wall charger. I already have some awesome status collected for Amperelicious (my Model 3); it would be fun to include the wall charger in that as well. I like your dashboard. At first I thought you had done it in Grafana, which is what Teslamate uses.

I would like to dig into these more as well. I use Home Assistant and it queries/updates every few seconds. I thought it was interesting that the Voltage C readout was 120V, yet had as high of amperage (32A) as voltage A, which was at 240V. Voltage B was also 240V, but much lower amperage.

Tesla doesn't do a very good job documenting their APIs. I've been exploring their API for communicating with cars, and most of what's out there comes with warnings that the API was found via reverse engineering and was not publicized by Tesla.

Ha ha ha, no they don't do a good job on that, they are also bad at making fish sandwiches.

 

[duunoit]

They are probably pretty good at documenting their APIs... they don't do a very good job at sharing/publishing them.
