Magic, cheers angus! That does appear to be working.
I’ll see if i can get a nice dashboard knocked up for it now and some automations from Bruce.

Im just trying to work out the best automation from Bruce that i need.
I just want the PW to charge from 23:45 and switch back Time based consumption at 5am?
I cant appear to find a simple solution? - My automations dont appear to be working either (which is just seting the battery reserve to 90% at 23:45 and back to 10% at 5:30 (if i set it via the dev menu, this works)
Hi Rob,
Im sure there is a million ways to skin this cat 
Bruce’s automations are quite complex and using lots of other sensors and binary_sensors.
A simple way to do what you want would be to create a toggle helper switch, I called mine “pw2_tou” to allow me to manually put the PW in to manual charge over ride.
Then create this automation in the UI:
alias: Powerwall: Turn ON TOU and 90% Back-up mode
description: ""
trigger:
- platform: state
entity_id:
- input_boolean.pw2_tou
from: "off"
to: "on"
- platform: time
at: "23:45:00"
condition: []
action:
- service: tesla_gateway.set_operation
data:
real_mode: autonomous
backup_reserve_percent: 90
- service: input_boolean.turn_on
data: {}
target:
entity_id: input_boolean.pw2_tou
mode: single
And this second automation to turn it off and back in to back_up mode:
alias: Powerwall: Turn OFF TOU and switch to Back-up 10% Reserve
description: ""
trigger:
- platform: state
entity_id:
- input_boolean.pw2_tou
from: "on"
to: "off"
- platform: time
at: "05:30:00"
condition: []
action:
- service: tesla_gateway.set_operation
data:
real_mode: backup
backup_reserve_percent: 10
- service: input_boolean.turn_off
data: {}
target:
entity_id: input_boolean.pw2_tou
mode: single

Really helpful thanks mate - the bit i was missing was the mode to change it back to Time based control - didnt reallise it was “autonomous” i tried all sorts haha
Congratulations everyone! yours is working and mine is not (yet). I’ve just trawled through 290 posts and am struggling to get a definitive set of “instructions”. Given that we now appear to have a working solution, might someone be good enough to share a complete set up? I’d really appreciate it and I am sure there are others like me!
OK I will try to make it as easy as I can remember:
- Install or you must already have installed the built-in Terminal editor available from the Integrations page. /config/integrations. Setting up terminal can be a challenge and you will need to search for how to do that if you are struggling with the public/private key set-up.
1a) install teslapy following these instructions:
- Follow these instruction to install teslpy in to your HA machine using the Terminal commands listed below (after the “filename.py” example below). Create this filename.py file that you will run in the terminal to create the cache.json file (dont forget to enter your Tesla account email on the second line):
filename.py:
import teslapy
tesla = teslapy.Tesla('<insert email address here>')
if not tesla.authorized:
print('Use browser to login. Page Not Found will be shown at success.')
print('Open this URL: ' + tesla.authorization_url())
tesla.fetch_token(authorization_response=input('Enter URL after authentication: '))
vehicles = tesla.vehicle_list()
print(vehicles[0])
tesla.close()
Continue with the Terminal window to now execute the filename.py using these instructions: create the cache.json file that requires the token from the Tesla Token app. Add support for Tesla Powerwall - #271 by robjones

Install “tesla_gateway” from the HACs store restart HA.

Install tesla_gateway in the integrations of HA, Restart HA.

using the Editor function navigate the the “custom_components/tesla_gateway” folder and replace these files with the below from Robjones init.py, manifest.json, services.yaml OR you can simply open each file and replace its contents with the below:

Ensure that the cace.json file that you created in step 2 above is present in the /config root directory of HA. As good measure copy it to the /config/custom_components_tesla_gateway" folder. I think it only needs to be in the /config ROOT folder to work unless you added the redirection line in to the init.py file above.
-
Restart HA. Check in the Integrations and you will probably see that the error for “tesla_gateway” failed to start.
-
Go to the Developers section in HA. then to Services and type in the search “set” scroll down and you should have two entries there for “tesla_gateway” being like below (if they are there then you have done it and running the commands from services should yield in the PW2 App changing states of TBC and Self-Consumption.

I do feel your pain, this method is overly complex, error prone and doesn’t give much feedback if it is actually working, but is currently necessary as this integration hasn’t been completely setup for authentication, hence the workaround.
I do however have some good news, there is a completely rewritten HA integration that provides fully integrated control and monitoring of powerwall and other Tesla energy products which is about to be released for development testing, so please stay on this chat and I’ll ensure details are released when it is ready.

Following - let me know if i can help do any of the testing - more than happy to help out and fully test it - looking forward to seeing this.

Will need a lot of testing with different configurations so your offer of assistance will be important.

thanks for your response Mark, that is indeed good news and I look forward to seeing it evolve. I too will be more than happy to be a beta tester as appropriate!

Happy to be a tester to, as getting nowhere fast at present with controlling the Powerwall 2
Did you follow the guide that I posted above?
I did, but its failing in Teslapy with a web service call, but the detail is obscured at the moment as to what is actually happening. Just double checking everything and trying to setup remote debugging.
You are only following this post and not any earlier, right? Looking at the file you posted it is an earlier version and not the one that I posted in my guide…
Yes that is one I followed; I did struggle a bit with step 2 as the instructions for installing Teslapy are missing in the step, but I found the Github repository and followed those instructions. So the homeassitant container does has Teslapy 2.6.0 installed. What file did you think was wrong?

Updated with that step…
wow, I just found this thread!
I’ve been doing this all by hand, and it’s great to be able to add this to home assistant! I wonder if someone might make this into a HACS module someday?
I posted this one, but it wasn’t the same as the one you quoted above:
import teslapy
tesla = teslapy.Tesla('<insert email address here>')
if not tesla.authorized:
print('Use browser to login. Page Not Found will be shown at success.')
print('Open this URL: ' + tesla.authorization_url())
tesla.fetch_token(authorization_response=input('Enter URL after authentication: '))
vehicles = tesla.vehicle_list()
print(vehicles[0])
tesla.close()
The Tesla Custom Integration is now available for testing and provides control and monitoring over Tesla vehicles as well as energy products including powerwall, allowing changing operating mode, backup reserve. This is a breaking change if you already have the integration installed.
This rewrite greatly simplifies authentication using the standard HA config flow, so you no longer need shell commands and copying json files around!
You can install by including as a custom repository in
You need to install the dev version:
Happy to take comments here, but please raise any issues in GitHub.
