Python Examples for API Calls now that Authorisation is sorted

[Pyromancer579]

With lots of help, I have managed to implement @timdorr 's work thanks to @skimike02 and @dvermagithub and it looks like the tokens now work for me.

But the code I had previously been using for API calls to control my Powerwall (switch its modes) when my conditions were met, doesn't seem to work, I've put the code below and the response I get:

256    async def Boost():
257        client = TeslaApiClient(TES_ID, TES_PW)
258        energy_sites = await client.list_energy_sites()
259        assert(len(energy_sites)==1)
260        N_MODE = await energy_sites[0].get_operating_mode()
261        if N_MODE==C_MODE:
262            await energy_sites[0].set_operating_mode('backup')
263            N_MODE = await energy_sites[0].get_operating_mode()
264        await client.close()

File "/home/pi/ZappiPowerwall/QuaterHourCheck.py", line 258, in Boost
energy_sites = await client.list_energy_sites()
File "/home/pi/.local/lib/python3.7/site-packages/tesla_api/init.py", line 106, in list_energy_sites
return [_class(self, products['energy_site_id']) for products in await self.get('products')]
File "/home/pi/.local/lib/python3.7/site-packages/tesla_api/init.py", line 79, in get
await self.authenticate()
File "/home/pi/.local/lib/python3.7/site-packages/tesla_api/init.py", line 67, in authenticate
expiry_time = timedelta(seconds=self.token['expires_in'])
KeyError: 'expires_in'

Can anyone point me in the direction of some example Python API calls for use with the new token system? so I can edit my code and make it work again.

@Pyromancer579 Here are the only two API calls I am currently making with the new token system:

def GetProducts(access_token):
    url="https://owner-api.teslamotors.com/api/1/products"
    headers = {"Authorization": "Bearer "+access_token}
    payload={}
    r = requests.get(url, data=json.dumps(payload), headers=headers)
    if r.status_code!=200:
        a="Error: http response "+str(r.status_code)+" "+r.reason
        return a
    else:
        a=json.loads(r.content.decode('utf-8'))
        response=a['response']
        return response
    
def GetSolarHistory(access_token,site_id,date):
    url=f"https://owner-api.teslamotors.com/api/1/energy_sites/{site_id}/calendar_history"
    headers = {"Authorization": "Bearer "+access_token}
    payload={}
    kind='power'
    period='day'
    end_date = date.replace(hour=7, minute=59, second=59)+datetime.timedelta(days=1)
    end_date=end_date.isoformat()
    params={'kind':kind,'period': period}
    params['end_date']=end_date+'Z'
    r = requests.get(url, data=json.dumps(payload), headers=headers, params=params)
    if r.status_code!=200:
        a="Error: http response "+str(r.status_code)+" "+r.reason
    else:
        a=json.loads(r.content.decode('utf-8'))
    return a['response']

All API calls work the same in the new system as the old system. You just have to pass a new access token. It looks like your old calls did something with the token expiration date. Maybe you were checking to see if the token needed refreshing each time? You could just delete those parts of the code. My implementation is to check once a day to refresh tokens, then when making API calls, just assume the tokens are good. Alternatively, you could try the access token, and only try to refresh if it doesn't work.

I would be curious what the structure of self.token in your code used to be, as it had a ['expires_in'] attribute previously. You will need to feed your API the same format now.

@skimike02 I tried using SetStatus as a basis for a new GetStatus with a .get replacing the .post, plus some other tweeks, but no luck, still getting 404 errors.

It would be really nice to be able to read the Status (Mode) of my Gateway (Energy Site) before changing it - Any thoughts?

If not, I'll have to brute force it using SetStatus and assume it has worked, rather than checking first and afterwards to see the status and then taking action accordingly.

[skimike02]

GetStatus worked for me. I have solar plus powerwall, if that makes a difference. Make sure you are using the battery id, not the site id. Short of that, not sure why it wouldn't work. Maybe you could look at what the request is. Run the following (make sure to strip out your access token and other sensitive data from the last print statement if you post the results here):

battery_id=GetBatteries(access_token)[0]
url=f"https://owner-api.teslamotors.com/api/1/powerwalls/{battery_id}"
headers = {"Authorization": "Bearer "+access_token}
payload=[]
r = requests.get(url, data=json.dumps(payload), headers=headers)
print(r)
print(r.content)
print(r.request.__dict__)

@skimike02 I too have solar PV and a Powerwall, but I only get the information about an 'Energy Site' (presumably my Gateway2) on the Products List - it only mentions a Powerwall under 'components', but it does show the Powerwall charge state as part of the the data associated with the 'Energy Site':

Product List = [{'energy_site_id': ???????, 'resource_type': 'battery', 'site_name': 'My Address', 'id': 'Kind Of My Name + Some Numbers', 'gateway_id': '1152100-03-E--TG????????????', 'asset_site_id': 'af80c37d-972c-4d6b-bca4-779609c368a5', 'energy_left': 8368.473684210529, 'total_pack_energy': 13699, 'percentage_charged': 61.088208513107, 'battery_type': 'ac_powerwall', 'backup_capable': True, 'battery_power': 590, 'sync_grid_alert_enabled': True, 'breaker_alert_enabled': False, 'components': {'battery': True, 'battery_type': 'ac_powerwall', 'solar': True, 'grid': True, 'load_meter': True, 'market_type': 'residential'}}]

I think it's just a quirk of the way my system was set up by the installer, that causes my Powerwall not to be listed separately on the Products List and this stops your GetStatus code working.

My 'brute force' implementation is now up and running, I'll test it for a few days and then publish it on here and elsewhere so others can benefit.

Thanks for your help, I would never have gotten my system working again without your much appreciated input.

[skimike02]

The product list above looks like mine. id:'Kind Of My Name + Some Numbers' is the battery_id needed for the code above. You could try putting that into the code above to see what response you get.

[Pyromancer579]

@skimike02 Your code does work, it was just my limited knowledge of Python and shoddy implementation that messed it up - My Bad!

Thanks to your code I can now read the status of my Powerwall.

My Brute Force system is working well, now to finesses it to minimise unneeded calls.

Thanks again for your assistance.
